This plate body. The fiber filter material (5, 6) that has just been made is a rectangular parallelepiped or cube having an appearance specific gravity of 0.7 to 0.92, a thickness of 3 to 30 mm, a width of 5 to 30 faces, and a length of 5 to 30 mm. The fiber filter material (5, 6) is cut by sandwiching the adhesive foamable resin plate (6a) with the plate-like body, and the appearance specific gravity is adjusted to 0.92 or less. As an ideal form, agitating blades are arranged at a plurality of places on the shaft (1 0) of the agitator (9). The stirring blades (1 1 a, 1 1 b) provided near the two side walls are inclined approximately 45 degrees with respect to the axis, and the other stirring blades (1 1 c) are arranged parallel to the axis. One end of the shaft (10) is a side wall penetrating the filter tank (1), and is connected to the driving machine 30. -6- (3) 1225801 As an ideal form, at least one of the above-mentioned air diffusers (8) is arranged at a position of 15 to 75 degrees below the horizontal axis of the filter tank (1) as an ideal form. In a form, when agitating the filter layer (7) with a mixer (9) and a diffuser pipe (8), the amount of air used for the diffuser is 10 to 20 Nm3 / m2 · Hr. As an ideal form, when the agitator (9) is stopped and the filter material layer (7) is agitated by a diffuser pipe (8), the amount of air used for diffuser is 15 to 25 Nni3 / m2 · Hr. As an ideal form, the filter includes a bottom portion stretched to the lower part of the filter tank (1), an end portion connected to the raw water supply pipe (3 4), and a drain outlet (3 5) at the opening. A cylindrical screen (32) at the other end. The aforementioned filter includes a screen conveyor (3 3) built in the screen (32). As an ideal form, a plurality of raw water supply pipes (3 4) and a plurality of drain outlets (3 5) are arranged at the lower part of the screen (3 2). A filter device according to a second feature of the present invention is a filter tank including a fluid and a filter material capable of floating on the fluid. The filter device includes a supply device for supplying bubbles from a position below the filter tank and away from the horizontal axis in a horizontal direction, and moving the fluid and the filter medium in a rotation direction centered on the horizontal axis. In a preferred form, the filter medium includes a group of fibers having different diameters.

The fiber filter material is a plate material cut out to make a filter material; or a low specific gravity foamable resin plate is sandwiched and bonded by the plate shape and cut. Therefore, in combination with the characteristics of the original solution or the treatment method, the specific gravity of the filter medium is optimally formed, and the compression resistance will not be reduced even if it is used for a long time, and the reduction of the processing capacity can be prevented. Therefore, it is possible to perform stable continuous operation for a long time. In order to wash and regenerate the floating fiber filter material having a specific gravity of 1.0 or less, when a diffuser pipe and a mechanical stirrer are used, the swirling flow formed by the stirrer and the spout from the diffuser pipe are used.

In addition, since one side wall of the filter tank provided with the shaft of the agitator is extended to the other side wall, a plurality of stirring blades are arranged. The number of stirring blades can be efficiently rotated, and the filter medium can also be small. Power is done. In addition, since the fiber filter material has a large porosity, the porosity of the filter material layer is also large, and the pressure loss is small to perform high-speed filtration, so that stable treated water can be obtained. Agitating blades are provided at a plurality of positions on the shaft of the agitator, and the agitating blades provided on both ends of the shaft are inclined approximately 45 degrees with respect to the shaft center, and other agitating blades are disposed parallel to the shaft center. Therefore, there will be no filter material stagnation during stirring. When stirring the filter material, the filter material can take the swirling flow generated by mechanical stirring and air stirring through the concrete to swirl efficiently, and can be fully washed. Regenerates and shortens washing time. When processing raw water mixed with stones or large solids, the stones or large solids are separated by the sieve of a filter tank and discharged to the outside by a screen conveyor.
【實施方式】 本發明之過濾機是如上所述之結構，生水是從由流入 口分歧成複數支的供給管，由過濾槽的底部供給至過濾室 內。在過濾室內，於供給管的上方與生水的流入方向呈平 行地張設有整流板。生水是沿著此整流板被均等地供給至 過濾室內。在使以浮上性的纖維濾材來形成的濾材層上升 之間，含於生水中的固型成分是受到濾材層所捕捉。已經 分離的處理水是由開口於張設在過濾槽上部的集水板全面 之多數個小孔均等地流入至集水室。聚集至此集水室的處 -9- 1225801 (6) 理水是由過濾槽頂部排出至外部。如此，當持續進行過濾 操作時，若在濾材層產生堵塞，或過濾速度降低的話，須 要再生•洗淨濾材。爲了洗淨•再生濾材，首先停止生水 流入，打開排出閥，排出過濾是內的生水。此時，集水室 內的處理水通過集水板而與生水置換。在處理水通過集水 板，過濾室內的水位到達集水板的下面附近的時間點，關 閉洩水閥，停止生水排出。 然後，藉由驅動設在過濾槽內的攪拌機，並且由散 氣管噴出空氣，來在過濾室內產生迴旋流。構成濾材層的 濾材是藉由一邊搭乘此旋迴流迴旋，一邊反復進行濾材彼 此或濾材與氣泡之衝突，來剝離附著於濾材的表面或內部 之固形物。因在促進前述攪拌機所產生之旋迴流的位置配 設散氣管，所以至上部爲止可有效率地迴旋，能在短時間 由濾材剝離固形物。再者，根據濾材的污染狀態，能不使

及空氣的供給。然後，再次供給生水，殘存於集水室內的 洗淨排水與處理水置換爲止持續進行供給。若在置換的時 間點關閉排水閥，打開處理水閥，開始過濾操作的話，則 -10· (7) 1225801 可取出淸澈的處理水。以下，根據圖面，詳細說明使用本 發明之纖維濾材的過濾裝置的實施形態。 第1圖是本發明的第1實施形態之過濾裝置的正面圖 ，第2圖是第1圖的左側面圖。第3圖是沿著第1圖的 III-III線切斷的縱斷面圖。參照上述第丨至3圖詳細敘述 本發明的過濾裝置的結構。圓筒狀的過濾槽1是朝橫方向 設置，且具有密閉構造。在此過濾槽丨內的上部全面，呈 水平地張設有集水板2。集水板2是以例如具有穿孔金屬 等的多數小孔之構件來構成的。過濾槽1是受到集水板2 所區隔。在過濾槽1中，較集水板2更上部是集水室3， 較集水板2更下部是過濾室4。生水是由並列地設置於過 濾槽1的生水連通管1 8流入口 1 9所流入，通過介設於生 水連通管1 8的流入閥1 1。該生水是通過連接於生水連通 管1 8的複數個供給管20，由過濾槽1的底部流入至過濾 槽1內。流入到過濾槽1的原液是受到張設於供給管2 0 的開口部的上方附近之整流板21所導引，被均等地供給 至過濾室4內。整流板2 1是較供給管20的開口部的寬稍 大。整流板21是與生水的流入方向平行地由過濾槽1的 槽壁張設至另一方的槽壁。在整流板2 1，使用具有穿孔 金屬等的多數小孔之構件。在過濾室4內塡充有浮上性的 纖維濾材5、6，形成預定厚度的濾材層7。濾材層7的厚 度是與過濾槽1的直徑成比例，變厚。 生水中的固形物是藉由上述濾材層7來捕捉。生水通 過集水板2流入至集水室3。在集水室3的頂部連結有複 -11 - (8) 1225801 數個集水管3 1。集水管3 1的另一端是連結集合於處理 連通管22。流入到集水室3的處理水是通過介設於處 水連通管22的處理水閥13，由處理水取出口 23取出 外部。再者，處理水連通管22是在處理水閥1 3的正前 分歧，介裝排水閥1 4而連接於L字形的排水管2 4，而 其終端部作爲排水口 2 5。然後，排水管2 4在排水口 之正前方與介裝有洩水閥16的洩水管26連接。洩水 26的另一端是開口於過濾槽1的底部。又在過濾室4 ’散氣管8及攪拌機9配設於過濾槽1的橫長方向。散 管8是由過濾槽1的一方之側壁至另一方的側壁，沿 水平軸延設，又配設於過濾室4下方的周壁附近。攪拌 9是配設於對於垂直軸，與散氣管8相反側的周壁附近 也就是當進行攪拌時，不會與濾材層7的下面干涉之位 。在處理水連通管22的頂部，設有用來將過濾槽1內 空氣放出至大氣的空氣除去閥2 7。在過濾槽1設置檢 用的人孔28。在過濾室4設置檢視窗29。 其次，根據第4A至4C圖，詳細說明攪拌機。嵌

材5、6聚集於過濾槽1的中央部。攪拌葉1 1 c是因在軸 1 〇的周圍使迴旋的流動產生，所以動作成將纖維濾材5、 6朝上下方向，也就是以過濾槽1的水平軸爲中心迴旋。 其次，根據第5 A圖的流程圖、第5 B及6圖的時間 圖，說明關於本發明的過濾工序。在過濾處理過程，打開 流入閥1 2與處理水閥1 3。生水由生水泵浦（未圖示）所 輸送，通過流入閥12，流入至過濾槽1的過濾室4。流入 到過濾室4的生水由濾材層7的下面上升，在通過濾材層 7之間捕捉生水中的固形物。生水變成淸澈水，通過集水 板2儲存至集水室3，由集水室3的上部通過處理水閥1 3 取出至外部。若持續過濾工序，濾材層7受到捕捉到的固 形物引起堵塞，使得過濾槽1內的壓力上升，過濾速度逐 漸降低。若形成如此的狀態的話’則須要洗淨·再生濾材 層7。爲了檢測濾材層7的堵塞，壓力開關等（未圖示） 檢測過濾槽1內的壓力。若壓力開關檢測到爲設定壓力以 上的話，則停止過濾工序，進行濾材層7的攪拌•洗淨過 程。 其次，說明關於濾材層7的攪拌•洗淨過程。停止生 水泵浦（未圖示），關閉流入閥1 2與處理水閥1 3，結束 過濾工序。接著，在攪拌工序之前進行攪拌準備工序。首 -13- (10) 1225801 先，打開洩水閥1 6，使儲存於集水室3內的處理水逆流 至過濾室4 ’由洩水閥1 6排出殘留於過濾室4內的生水 。然後’再過濾室4內的液面變得較集水板2更低的時間 點，關閉洩水閥1 6。接著，移行至濾材層7的攪拌工序 。首先，使攪拌機9驅動，並且打開空氣供給閥1 5，由 散氣管8供給空氣。使用於散氣之空氣量是例如〗〇〜 20Nm3/m2 · Hr。攪拌機9是朝如第5圖所示的箭號p方 向旋轉。藉此，在過濾室4的下部，在箭號Q方向發生 迴旋流。箭號Q的迴旋流是藉由散氣管8所供給的空氣 增加速度而上升，在過濾室4的上部形成箭號R方向的迴 旋流。藉由此箭號Q及箭號R的迴旋流，構成濾材層7 的纖維濾材5、6搭乘此迴旋流，一邊朝上下迴旋，一邊 使纖維濾材5、6彼此反復衝突，或纖維濾材5、6與來自 於散氣管8的空氣之氣泡衝突。藉此，剝離了附著於纖維 德材5、6的表面或內部之固形物。由散氣管8所供給的 空氣是由配設於處理水連通管22的頂部之空氣除去閥27 釋放到大氣中。然後，停止攪拌機9，關閉空氣供給閥1 5 使攪拌工序結束。接著，進行纖維濾材5、6的洗淨。再 者，前述散氣管8是在第5A、5B圖，以過濾槽1的水平 軸〇爲中心，在由水平線HL朝下方1 5〜75度的位置配 設複數支（在第3圖爲2支）。散氣管8是因應纖維濾材 5、6的污染度或運轉狀況，適宜選擇使用1支或複數支 〇 首先，打開洩水閥1 6排出過濾室4的污水，在排水 -14- 1225801 (11) 結束後，關閉洩水閥1 6。然後，打開排水閥1 4與洗淨水 閥1 7，將洗淨水供給至過濾槽1內。當過濾槽丨大致形 成滿水時，驅動攪拌機9，打開空氣供給閥1 5，供給空氣 。藉由以迴旋流將纖維濾材5、6 —邊攪拌一邊洗淨，來 除去殘留於纖維濾材5、6之細微粒子。洗淨排水是由集 水室3通過排水閥14，排出至外部。當纖維濾材5、6的 洗淨•再生結束後，停止攪拌機9，關閉空氣供給閥i 5 與洗淨水閥1 7。打開流入閥1 2、由生水泵浦（未圖示） 將生水供給至過濾室4內，將殘存於集水室3內的洗淨排 水與處理水置換（捨水工序）。然後，關閉排水閥1 4， 打開處理水閥1 3的話，結束捨水工序，完成纖維濾材5 、6的洗淨·再生。然後接著，再開始過濾工序。再者， 洗淨排水中的固形物污濁度低的情況時、或固形物的比重 小的情況時，也會有已經分離的固形物再次附著到纖維濾 材5、6之虞。因此，也會有在攪拌結束後，不實施排水 工序，緊接著進行洗淨工序的情況。 再者，在攪拌工序，亦可停止攪拌機9，藉由來自於 散氣管8的氣泡，來攪拌濾材層7。在此情況時，使用於 散氣之空氣量是15〜25Nm3/m2· Hr。 參照第5 B圖，說明散氣管的安裝位置與攪拌效果的 關係。在此說明，以對於水平軸〇圖上右的水平線HL爲 基準，逆時針周圔作爲正的角度。第1，在過濾槽1內， 於對於水平線HL，-15 °至+1 80 °的範圍A將散氣管定位 。在此情況時，僅散氣管8的上部與攪拌機9周邊的濾材 -15- 1225801 (12) 流動，濾材層7全體並未流動。 第2，在對於水平線HL，+180 °〜+240 °之範圍B將 散氣管8定位。在此情況時，散氣管8的上部與攪拌機9 周邊的濾材流動’但濾材層7全體並未流動。

by a plurality of supply pipes branched from an inflow port. In the filter chamber, a rectifying plate is provided in parallel with the inflow direction of the raw water above the supply pipe. Raw water is uniformly supplied into the filter chamber along this rectifying plate. While the filter medium layer formed by the floating fiber filter medium is raised, the solid component contained in the raw water is captured by the filter medium layer. The separated treated water flows into the water collecting chamber uniformly through a plurality of small holes in the entire surface of the water collecting plate opened in the upper part of the filtering tank. Where it collects in this water collection chamber -9- 1225801 (6) The water is discharged from the top of the filter tank to the outside. In this way, when the filtration operation is continued, if the filter material layer becomes clogged or the filtration speed is reduced, the filter material needs to be regenerated and washed. To clean and regenerate the filter medium, first stop the flow of raw water, open the drain valve, and drain the raw water in the filter. At this time, the treated water in the water collecting chamber is replaced with the raw water by the water collecting plate. When the treated water passes through the water collecting plate and the water level in the filter chamber reaches near the lower surface of the water collecting plate, the drain valve is closed to stop the discharge of raw water. Then, a stirrer provided in the filter tank is driven, and air is ejected from a diffuser pipe to generate a swirling flow in the filter chamber. The filter medium constituting the filter medium layer peels off the solid matter attached to the surface or the inside of the filter medium by repeatedly repeating the filter mediums or the conflict between the filter medium and the air bubbles while riding the swirling flow. Since the air diffuser is provided at a position that promotes the swirling flow generated by the agitator, it can be efficiently swiveled up to the upper part, and the solid can be peeled from the filter material in a short time. Furthermore, depending on the contaminated state of the filter medium, it is possible to regenerate the filter medium using only air from the air diffuser without using a stirrer. Then, the supply of the agitator and air was stopped, and the drain valve was opened to discharge the sewage in the filter chamber. When the discharge is completed, the drain valve is closed, the washing water is supplied from the raw water inlet, and the drain valve is opened. After a predetermined time has elapsed, the agitator is driven to eject air from the diffuser pipe to generate a swirling flow to clean the solids remaining in the filter medium. The washing drainage is discharged to the outside through the drainage valve. As described above, when the cleaning and regeneration of the filter medium is completed, the supply of the agitator and air is stopped. Then, the raw water is supplied again, and the washing and drainage remaining in the water collecting chamber are continuously replaced with the treated water. If the drain valve is closed at the time of replacement, the treated water valve is opened, and the filtering operation is started, then -10 · (7) 1225801 can take out the clear treated water. Hereinafter, embodiments of a filtering device using the fiber filtering medium of the present invention will be described in detail with reference to the drawings. Fig. 1 is a front view of a filtering device according to a first embodiment of the present invention, and Fig. 2 is a left side view of Fig. 1. Fig. 3 is a longitudinal sectional view taken along line III-III of Fig. 1. The structure of the filtering device of the present invention will be described in detail with reference to the above-mentioned FIGS. The cylindrical filter tank 1 is provided in a horizontal direction and has a closed structure. The upper part in the filtering tank 丨 is full, and the water collecting plate 2 is horizontally stretched. The water collecting plate 2 is constituted by a member having many small holes such as perforated metal. The filter tank 1 is partitioned by the water collecting plate 2. In the filter tank 1, a water collecting chamber 3 is located above the water collecting plate 2 and a filtering room 4 is located below the water collecting plate 2. The raw water flows in through the inflow port 19 of the raw water communication pipe 18 provided in the filter tank 1, and passes through the inflow valve 11 interposed in the raw water communication pipe 18. The raw water flows into the filter tank 1 from the bottom of the filter tank 1 through a plurality of supply pipes 20 connected to the raw water communication pipe 18. The raw liquid flowing into the filter tank 1 is guided by a rectifying plate 21 stretched near the upper portion of the opening of the supply pipe 20 and is uniformly supplied into the filter chamber 4. The fairing plate 21 is slightly larger than the width of the opening of the supply pipe 20. The rectifying plate 21 is stretched from the tank wall of the filter tank 1 to the other tank wall in parallel with the inflow direction of the raw water. For the rectifying plate 21, a member having many small holes such as perforated metal is used. The filter chamber 4 is filled with floating fiber filter materials 5, 6 to form a filter material layer 7 of a predetermined thickness. The thickness of the filter medium layer 7 is thicker in proportion to the diameter of the filter tank 1. The solid matter in the raw water is captured by the filter medium layer 7 described above. The raw water flows into the water collecting chamber 3 through the water collecting plate 2. A plurality of water collecting pipes 31 are connected to the top of the water collecting chamber 3-(8) 1225801. The other end of the water collecting pipe 31 is connected to the processing communication pipe 22. The treated water flowing into the water collection chamber 3 is taken out through the treated water outlet 23 through the treated water valve 13 interposed in the water communication pipe 22. In addition, the treated water communication pipe 22 is branched in front of the treated water valve 13 and is connected to the L-shaped drainage pipe 2 4 through the drainage valve 14 and the terminal portion thereof serves as the drainage port 25. Then, the drain pipe 24 is connected to the drain pipe 26 in which the drain valve 16 is interposed in front of the drain port. The other end of the drain 26 is opened at the bottom of the filter tank 1. In the filter chamber 4 ', the air diffusing pipe 8 and the agitator 9 are arranged in the lengthwise direction of the filter tank 1. The diffuser pipe 8 extends from one side wall to the other side wall of the filter tank 1 along the horizontal axis, and is arranged near the peripheral wall below the filter chamber 4. The agitation 9 is arranged near the peripheral wall on the side opposite to the diffuser tube 8 for the vertical axis, that is, the agitation 9 does not interfere with the lower surface of the filter material layer 7 when agitation is performed. An air removal valve 27 is provided on the top of the treated water communication pipe 22 to release the air in the filter tank 1 to the atmosphere. The filter tank 1 is provided with a manhole 28 for inspection. An inspection window 29 is provided in the filter chamber 4. Next, the mixer is explained in detail based on FIGS. 4A to 4C. The shaft 10 of the drive machine 30 embedded in the mixer 9 is extended from one wall of the filter tank 1 to the vicinity of the other side wall. At both ends of the shaft 10, stirring blades Π a and 1 lb inclined at a 45-degree angle to the shaft center are provided. Both parts of the shaft 10 are supported by bearings 10a at positions adjacent to the stirring blades 1a and 1b. The bearing 10 A is supported by a supporting member 10b fixed to the wall of the filter tank 1. Further, a plurality of stirring blades 1 1 c are arranged flatly on the shaft center between the bearings 10 a. Furthermore, in FIG. 4, the agitating water treatment described above aerates the inside of the 25 tube, and the end of the installation side has a bearing -12- (9) 1225801 1 1 a is the shaft for the shaft 10 Heart, inclined 45 degrees downward. The stirring blade 1 lb is tilted 45 degrees to the axis. The stirring blades 1 la and 1 lb generate flows toward the center of the shaft 10, respectively. In addition, the bearings 10a and 10b operate to collect the fiber filter materials 5 and 6 near the side wall at the center of the filter tank 1 when the mixer 9 is driven. The stirring blade 1 1 c generates a swirling flow around the shaft 10, so the fiber blades 5 and 6 are moved in an up-and-down direction, that is, the horizontal axis of the filter tank 1 is rotated. Next, the filtration process according to the present invention will be described with reference to the flowchart in Fig. 5A and the timing charts in Figs. 5B and 6. During the filtering process, the inflow valve 12 and the treated water valve 1 3 are opened. The raw water is transported by a raw water pump (not shown), passes through an inflow valve 12, and flows into the filter chamber 4 of the filter tank 1. The raw water flowing into the filter chamber 4 rises from below the filter medium layer 7 and captures solids in the raw water between the passing filter medium layers 7. The raw water becomes clear water, is stored in the water collecting chamber 3 through the water collecting plate 2, and is taken out from the upper part of the water collecting chamber 3 through the treatment water valve 1 3 to the outside. If the filtering process is continued, the filter material layer 7 is clogged by the captured solids, causing the pressure in the filter tank 1 to rise, and the filtering speed to gradually decrease. In such a state, it is necessary to clean and regenerate the filter medium layer 7. In order to detect clogging of the filter medium layer 7, a pressure switch or the like (not shown) detects the pressure in the filter tank 1. If the pressure switch detects that the pressure is equal to or higher than the set pressure, the filtering process is stopped and the filter material layer 7 is stirred and washed. Next, the process of stirring and cleaning the filter material layer 7 will be described. Stop the raw water pump (not shown), close the inflow valve 12 and the treated water valve 1 3, and end the filtration process. Next, a stirring preparation step is performed before the stirring step. First -13- (10) 1225801 First, open the drain valve 16 so that the treated water stored in the water collection chamber 3 flows back to the filter chamber 4 '. The drain valve 16 discharges the raw water remaining in the filter chamber 4. . Then, at a point in time when the liquid level in the 're-filtration chamber 4 becomes lower than that of the water collecting plate 2, the drain valve 16 is closed. Next, the process proceeds to the stirring step of the filter medium layer 7. First, the agitator 9 is driven, the air supply valve 15 is opened, and air is supplied from the diffuser pipe 8. The amount of air used for diffusing air is, for example, 〖〇 ~ 20Nm3 / m2 · Hr. The mixer 9 is rotated in the direction of arrow p as shown in FIG. 5. As a result, a swirling flow occurs in the lower part of the filter chamber 4 in the direction of the arrow Q. The swirling flow of the arrow Q rises with the increasing speed of the air supplied from the air diffusing pipe 8, and a swirling flow of the arrow R direction is formed on the upper part of the filter chamber 4. By the swirling flow of the arrow Q and the arrow R, the fiber filter materials 5 and 6 constituting the filter material layer 7 ride on this swirling flow, and while rotating up and down, the fiber filter materials 5 and 6 repeatedly conflict with each other, or the fiber filter materials 5, 6 collides with air bubbles from the air diffusing tube 8. Thereby, the solid matter adhering to the surface or the inside of the fiber material 5, 6 is peeled off. The air supplied from the air diffusing pipe 8 is released into the atmosphere by an air removing valve 27 provided on the top of the treated water communication pipe 22. Then, the agitator 9 is stopped and the air supply valve 15 is closed to complete the agitating process. Next, the fiber filters 5 and 6 are washed. In addition, in the FIGS. 5A and 5B, the diffuser pipe 8 is centered on the horizontal axis 0 of the filter tank 1, and a plurality of branches are arranged at positions 15 to 75 degrees downward from the horizontal line HL (2 in FIG. 3). support). The air diffusing pipe 8 is suitable for use according to the pollution degree or operating condition of the fiber filter materials 5 and 6. It is suitable to use one or a plurality of them. First, open the drain valve 16 to drain the sewage from the filter chamber 4, and drain the water at -14-1225801. When finished, close the drain valve 16. Then, the drain valve 14 and the wash water valve 17 are opened, and the wash water is supplied into the filter tank 1. When the filter tank 丨 is substantially filled with water, the mixer 9 is driven to open the air supply valve 15 to supply air. The fine fiber particles 5 and 6 remaining in the fiber filter materials 5 and 6 were removed by washing the fiber filter materials 5 and 6 with a swirling flow while stirring. The washing and draining water is discharged from the water collecting chamber 3 through the drain valve 14 to the outside. After the fiber filter media 5 and 6 are cleaned and regenerated, the agitator 9 is stopped, and the air supply valve i 5 and the wash water valve 17 are closed. Open the inflow valve 1 2. Feed the raw water into the filter chamber 4 by the raw water pump (not shown), and replace the washing and draining water remaining in the water collecting chamber 3 with the treated water (water-retaining process). Then, when the drain valve 14 is closed and the treated water valve 13 is opened, the water-retaining process is completed, and the fiber filters 5 and 6 are washed and regenerated. Then, the filtration process was resumed. In addition, when the turbidity of the solid matter in the washing and draining water is low, or when the specific gravity of the solid matter is small, the separated solid matter may adhere to the fiber filters 5 and 6 again. Therefore, there may be a case where the drainage step is not performed after the completion of the stirring, and the washing step is performed immediately thereafter. In the stirring step, the stirrer 9 may be stopped, and the filter medium layer 7 may be stirred by the air bubbles from the air diffusing pipe 8. In this case, the amount of air used for diffusion is 15 to 25 Nm3 / m2 · Hr. The relationship between the installation position of the air diffuser and the stirring effect will be described with reference to Fig. 5B. Here, it is assumed that the horizontal angle HL on the right of the graph on the horizontal axis 0 is used as a reference, and the counterclockwise rotation is used as a positive angle. First, in the filter tank 1, the air diffuser is positioned in a range A of -15 ° to +1 80 ° for the horizontal line HL. In this case, only the upper part of the air diffusing pipe 8 and the filter material -15-1225801 (12) around the mixer 9 flow, and the entire filter material layer 7 does not flow. Second, the diffuser 8 is positioned in a range B from + 180 ° to + 240 ° for the horizontal line HL. In this case, the upper part of the diffuser pipe 8 and the filter material around the mixer 9 flow ', but the entire filter material layer 7 does not flow. Thirdly, the diffuser 8 is positioned in the range C from + 240 ° to +2 8 5 ° for the horizontal line HL. In this case, the filter medium around the mixer 9 and the lower portion of the filter medium flows, but the filter medium near the water collection chamber 3 on the upper side of the filter layer 7 does not flow. Therefore, the entire filter material layer did not flow. Number 4, at +285 for the horizontal line HL. ~ + 3 4 5. , Or -15. Position D in a range of ~ -75 °. In this case, the filter medium layer 7 flows as a whole and rotates inside the filter tank. From the above results, it can be seen that it is good to arrange the diffuser in the range D. Figures 7 and 8 are perspective views of the floating fiber filters 5 and 6 used in the present invention. This fiber filter is a non-woven fiber filter made of three types of synthetic resin fibers with different fiber diameters. The first fiber yarn 5a is a heat-fusible composite fiber coated with polyethylene on a polypropylene core material, and has a fineness of 18 to 65 denier. The material of the second fiber filament 5b is polypropylene fiber, and its fineness is 3 to 10 denier. The third fiber filament 5c is a heat-fusible composite fiber coated with polyethylene on a polypropylene core material, and has a fiber g of 1.5 to 6 denier. The web with the fibers 5a, 5b, and 5c blended by acupuncture is shaped into a cloth, and the fleece on both sides of the web is heat-treated without being flat and smooth to form a plate-like body, and the board is cut Shape. The fiber material 5 is a rectangular parallelepiped or cube having an appearance specific gravity of 0.7 to 0.92, a thickness of 2 to 30 mm, a width of 5 to 30, (16) 1225801, a leg i, and a length of 5 to 30 thin. Since the fiber filter material 5 is composed only of polypropylene fibers, its specific gravity is approximately 0.92. When the specific gravity is adjusted to less than or equal to 0.92 ', as shown in FIG. 8, as in the fiber filter material 6, the foamable resin sheet 6 a is sandwiched in the above-mentioned plate state and then bonded and cut. For the foamable resin sheet 6a ', expanded polystyrene having a smaller specific gravity than that of the fiber filter material 6 is used. Thereby, the specific gravity can be arbitrarily adjusted from 0.7 to 0.9 2. Further, the specific gravity of the foamable resin plate 6a can be made smaller, and the specific gravity of the fiber filter material 6 can also be made 0 · 7 or less. As described above, the most suitable fiber filter materials 5, 6 can be selected in accordance with the raw water state or the filtration operation direction '. Fig. 9 is a filter device according to a second embodiment of the present invention. Used to treat raw water containing inclusions such as stones or cloth or sludge residues. In this case, if these inclusions or sludge residues are mixed into the filter tank 1, there is a possibility that the filter material layer 7 may be blocked early, or the mixer 9 may be damaged. In the case of filtering the raw water in this way, a pre-processing device such as a dust remover is provided at the front stage of the filtering device, and these inclusions or sludge residues are removed by the pre-processing device, followed by filtering. Fig. 9 shows a filter unit incorporating the above-mentioned dust remover. Sewage mixed with inclusions or sludge residues flows into the filter tank 1 through the raw water supply pipe 34. Then, a large-sized solid matter such as inclusions, sludge residues, etc. is removed by the cylindrical screen 32 2 stretched on the lower bottom of the filter tank 1. The raw water that has passed through the aforementioned screen 32 2 flows into the filtering chamber 4. This raw water is solid-liquid separated by the filter material layer 7, and the treated water is discharged from the top of the filter tank 1 to the outside. The inclusions or sludge residues captured by the aforementioned screen 3 2 are transferred to the drain outlet 3 5 through a screen 17- (14) 1225801 inside the screen 3 2, The drain outlet 35 is thereby discharged to the outside. The screen conveyor 3 3 is constituted by a screen shaft 3 3 a with a screen blade 3 3 b and a driver 36. By rotating the screen shaft 3 3 a ′ with the driver 36, the captured inclusions, sludge residues, and the like are continuously transferred from left to right in FIG. 9. In Fig. 10, a plurality of raw water supply pipes 3 4 and a plurality of drain outlets 35 are provided in the screen 32. When raw water containing a large amount of inclusions or sludge residues is mixed, the inclusions or sludge residues are concentrated in one place. Thereby, when the raw water flows into the filter chamber 4, it is possible to prevent the formation of impedance, and the raw water can be uniformly supplied to the filter chamber 4 on the screen 32. In Fig. 10, raw water supply pipes 34 are provided in three places, and drain outlets 35 are provided in two places. The screen blades 3 3 b are divided into four equal parts and are wound on a screen shaft 33 a. The screen blade 33b (the first one) at the left end of Fig. 10 can be moved to the right. Adjacent screen blades 33b (second) can be moved in the left direction. The third screen blade 33b can be moved in the same direction as the first, and the fourth screen blade 33b can be moved in the same direction as the second. Inclusions, sludge residues, etc. flowing in from the raw water supply pipe 34 at the left end are transferred to the first (left) drain outlet 35. Inflows, sludge residues, and the like flowing in from the central raw water supply pipe 34 are divided and transferred to the left and right drainage outlets 35. Inclusions, sludge residues, etc. flowing in from the raw water supply pipe 34 at the right end are transferred to the second (right) drain outlet 35, and discharged to the outside. With the above-mentioned structure, since large solids such as inclusions and sludge residues do not flow into the filtering chamber 4, it is possible to prevent early clogging of the filter material layer 7 and prevent the mixer 9 from being damaged. -18- (15) 1225801 In figures 1 1 A to 1 1 D, perforated metals 50a to 50d used in the water collecting plate 2 and the screen 32 of the above embodiment will be described. In FIG. 11A, the perforated metal 50a is a stainless steel sheet 51a and a circular hole 52a arranged in parallel to the sheet 51a. The diameter of the hole 52a is 1 to 3 mm, and is set smaller than the diameter (three legs) of the fiber of the filter medium.
