The present invention relates to a washing method and a washing device for flocked fabric, in which a cylindrical body surface is formed to have liquid permeability, a flocked fabric is attached on the cylindrical body surface to form a sieve, and suspended solids are removed. The liquid contained in the cloth is filtered through the flocked cloth, and the liquid is collected through a liquid pipe that also serves as a rotating shaft.When the flocked cloth becomes clogged with suspended matter and pressure loss increases, Water is passed through the flocked fabric in the opposite direction to backwash the flocked fabric, and air is supplied from the liquid pipe from the inside to the outside of the flocked fabric. This method is characterized by removing attached suspended substances. Conventionally, a method and apparatus for recovering clogging of a flocked cloth caused by passing suspended matter in a liquid through a flocked cloth attached to a liquid-permeable cylindrical body surface is disclosed in Japanese Patent Application Laid-Open No. 119168/1983. Either the natural water pressure of the liquid inside the cylinder can be used to peel off the suspended solids attached to the flocked cloth and backwash it, or a suction pump can be installed outside the cylinder to suck up the liquid inside the cylinder and suspend it. There are methods and apparatus for exfoliating materials. Generally, regardless of whether the suspended solids are inorganic or organic, even if they form relatively large flocs and are caught on the surface of the flocked cloth, they can be backwashed and treated using conventional methods. There is no deterioration in the quality of the liquid or decrease in throughput, and it performs extremely well even during long-term operation. However, if the suspended matter in the liquid is fine like a colloid or sticky, the suspended matter will settle at the base of the base fabric of the flocked cloth, making it difficult to use the conventional method. In the backwashing method, suspended solids cannot be removed from the base fabric of the flocked fabric, and the amount of suspended solids deposited increases over time, causing clogging of the flocked fabric and eventually making it impossible to clean. The present invention improves the deficiencies of conventional methods and devices for washing flocked fabrics by easily removing suspended matter that adheres to the flocked fabric and is difficult to remove with a small amount of liquid (backwashing liquid). The purpose of this method is to prevent clogging of the flocked cloth, and furthermore, to increase the processing efficiency by increasing the amount of processing liquid. Another object of the present invention is to concentrate and recover or remove suspended solids. Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the body surface of a cylinder 1 is formed to have liquid permeability, and an endless flocked fabric 8 is provided on the body surface of the cylinder. The over-tube 2 is attached, and the over-tube 2 is rotatably installed in the processing tank 3 via a hollow rotating shaft 4. In order to provide liquid permeability to the body surface of the cylinder 1, the body surface may be shaped like a grid 10 as shown in FIG.
As shown in the figure, it may be configured in a porous form 10',
Any other material may be used as long as the liquid can pass through and hold the flocked fabric 8. The rotating shaft 4 is attached to a bearing 16 of the processing tank 3, and one end is connected to a rotating gear 12 driven by a motor 13, and the other end is connected to a liquid pipe 14. A large number of liquid collection/distribution holes 5 are provided in this portion, and an aeration pipe 7 having a large number of air holes 9 coaxially connected to the air supply pipe 6 is provided within the rotary shaft 4. A stock solution pipe 15 is connected to the upper part of the processing tank 3, and a concentrated suspended solids extraction pipe 11 is connected to the lower part. Next, to explain the operation of the present invention, a stock solution containing suspended solids, particularly fine and sticky suspended solids, is flowed into the processing tank 3 from the stock solution pipe 15, and the motor 13 is driven to drive the drive gear (not shown). When the rotary gear 12 is rotated by the rotation gear 12, the overtube 2 rotates integrally with the rotary shaft 4 (1 to 10 rpm). The raw solution that has flowed into the treatment tank 3 passes through the flocked fabric 8 of the rotating overtube 2 from the outside to the inside, whereby suspended matter is captured by the flocked fabric 8, and the liquid is collected in the overtube 2. Then, the liquid flows out from the liquid collection and distribution hole 5 of the rotating shaft 4 into the liquid pipe 14. The flocked fabric 8 is a blanket-like woven fabric in which synthetic fibers of 1 to 30 deniers and pile length of 20 to 100 mm are flocked at 500 to 2000 g per 1 m 3 of base fabric. As shown in Figure 2A, the flocked long fibers overlap three-dimensionally, making the surface denser and increasing the thickness of the fabric, resulting in a thick layer. This is different from conventional micro strainers. Additionally, if the flocked cloth 8 becomes clogged with suspended matter, as shown in Figure 2B,
A backwashing liquid (liquid) that flows in the opposite direction to the direction in which the overlapping fibers were released releases the suspended matter that has accumulated on the cloth. That is, by supplying liquid as a backwash liquid from the liquid pipe 14 while rotating the over-tube 2, allowing it to flow into the over-tube 2 from the liquid collection and distribution hole 5 through the rotating shaft 4, and allowing the liquid to pass through the flocked cloth 8. During backwashing with this liquid, air is supplied to the air supply pipe 6 at the same time, and air is press-fitted (0.5 to 5 kg/cm 2,10 to 100Nm 3 /H/m 2 ), the suspended solids attached to the flocked cloth 8 can be easily peeled off in a short time by the mixed liquid and air, which is difficult to remove conventionally. It is possible to completely peel off fine suspended substances such as colloidal particles that have a sticky substance. Moreover, compared to the conventional case where only liquid is used, in the case of the present invention, due to the synergistic effect of the liquid and air, the amount of liquid used as backwash liquid is significantly reduced (half of the conventional amount).
(below) also has the advantage of saving money. In order to further enhance the synergistic effect of the liquid and air, as shown in FIG. An air diffuser 7 which is provided in a tubular shape rising from the shaft 4 and has an air hole 9 at its tip is provided at a position as close to the flocked cloth 8 as possible to uniformly supply air to a predetermined area of the rotating flocked cloth 8,
It is possible to peel and remove suspended solids and wash the flocked cloth 8 in a shorter time and with a smaller amount of backwashing liquid (liquid), especially very fine and highly adhesive suspended solids. Effective for peeling off. The suspended solids peeled off from the flocked cloth 8 settle to the bottom of the treatment tank 3, and are discharged or collected in a concentrated state through the concentrated suspended solid removal pipe 11. Examples of the present invention will be described below. Example 1 Cylindrical body with grid-like structure (diameter 1000 mm)
A 3-denier acrylic fiber with a pile length of 50 mm, a flocking density of 1500 g/m 3 , and an excess area of 0.75 m 2 was attached as a flocked cloth to form a overtube, and this overtube was placed in the treatment tank. Two sets of treatment tanks were prepared in which the tubes were rotatably loaded. Then, 350 m 3 of raw wastewater with a suspended solids concentration (average) of 100 ppm discharged from the papermaking process of a paper mill was flowed into each of the above treatment tanks at a flow rate of 14.5 m 3 /H, and at the same time the rotation speed of the tube was increased to 4 rpm. The method of the present invention is applied to one of the tubes when each of the planted beds becomes clogged with suspended solids. That is, as shown in Figure 1, pressurized air is supplied as backwash water (water) from the air hole of the air diffuser through the water collection and distribution hole of the rotating shaft under the conditions shown in Table 1, and the backwashing of the flocked cloth is carried out. Washing treatment was performed to remove suspended substances. In addition, in the other tube, as a conventional method, only backwash water was supplied under the conditions shown in Table 1 to backwash the flocked fabric and remove the suspended solids, but the removal was not successful. It was insufficient. As is clear from the above, the method of the present invention was able to reduce the amount of backwash water to 1/2 and shorten the backwash time by 30% compared to the conventional method. In addition, when the above-mentioned raw water was again passed through the backwashed flocked fabric for overtreatment, the results shown in Table 2 were obtained. In other words, the method of the present invention reduces the amount of treated water (
The amount of superfluous water increased by 35m3 , and the SS of the treated water was also reduced by several steps. Furthermore, the amount of concentrated suspended solids in the backwash wastewater (including the raw water in the treatment tank) was doubled. could be recovered at a concentration of
