It cannot be treated to release it, and it lacks denitrification ability, so it has no choice but to rely on anaerobic treatment. This invention aims to perform aerobic and aerobic treatment in one biological reaction tank and also to clarify the treated water.

A partition wall 2 is installed vertically in the center of the biological reaction tank 1 designated as a, with the upper edge slightly below the upper limit water level and the lower edge higher than the conical cavity 1a, with both sides reaching the tank walls. Accordingly, the tank is divided into tanks 3 and 4 in which the vicinity of the water surface and the bottom are connected to each other. At the bottoms of both tanks 3 and 4, aeration devices 5 and 6 such as diffuser pipes are installed approximately in the center of the tanks, and the air pipes 7 and 8 of each device 5 and 6 are automatically Air supply valves 9 and 10 that can be opened and closed automatically are installed, and these air supply valves 9 and 10 are electrically connected to a control panel 11 so that each can be opened and closed by a timer, and automatic operation is also possible using the control 11.

ことができる。 On the other hand, in this embodiment, expanded polystyrene particles are used as the contact material 21, and the mesh frame 22 is placed near the full water level.
is spread horizontally to prevent the contact material 21 particles from floating and swelling. Thus, first biological reaction tank 1
Sewage gradually flows into the tank until the aeration pipes 5 and 6 are hidden, and then the tank 3 on the left side in the figure
Perform aeration only. In this case, the contact material 21 tends to be pushed upward by the bubbles floating up from the aeration tube 5, but the left tank 3 is in an aerobic state and the microorganisms attached to the contact material 21 are in an aerobic state. Organic matter is decomposed and ammonia in wastewater is oxidized to nitric acid. This aeration time varies depending on the concentration and properties of the wastewater.
The cycle may be ~23 hours or shorter, 1 to 12 hours. Then, by the aeration operation, the wastewater automatically climbs over the upper edge of the compartment wall 2 and enters the tank 4 on the right side, which is not aerated, but here it becomes anaerobic and flows down from directly above the compartment wall 2 due to the action of denitrifying bacteria. When some of the sewage flows in, it is used as a carbon source to decompose nitric acid into nitrogen gas and carbon dioxide and release it into the atmosphere.
The wastewater is also subjected to anaerobic digestion. At this time, the alkalinity regenerated in the anaerobic section is circulated back to the aerobic section, which helps prevent the PH value from decreasing in the aerobic section, allowing nitrogen nitrification and denitrification to be carried out rationally. .
Then, by opening the treated water valve at an appropriate time, the treated water in the right-hand image tank 4 will quietly fall between the particles of the contact material 21, and the suspended matter will be captured by the particles of the contact material as if passing through. , clear treated water can be taken out.
しかる後、接触材２１の粒子中に浮遊物が充満
してきたと思われる時期に、左右両画槽３，４を
同時に５〜15分間位一斉に曝気すれば、上昇する
気泡と共に動く水流によつて、粒子相互が摩擦

するようにする。したがつて静置期間と汚泥排出
期間はブロワ運転は停止となり、次には逆に第２
図に示すように右側の画槽４を曝気して同様にし
て汚水処理操作を行なう。 After that, when the particles of the contact material 21 are thought to be filled with floating matter, if both the left and right tanks 3 and 4 are aerated for about 5 to 15 minutes at the same time, the water flow that moves with the rising air bubbles will The particles rub against each other and the attached sludge falls off, producing a backwashing effect for the pond.The operation of the blower 12 is therefore stopped and the sludge is allowed to stand still for 30 minutes to 2 hours. When the sludge suspended in the liquid settles to the bottom of the conical cavity 1a, excess sludge is discharged. Therefore, the blower operation is stopped during the standing period and sludge discharge period, and then the second blower is turned on.
As shown in the figure, the right tank 4 is aerated and the sewage treatment operation is performed in the same manner.
以上が処理操作の態様であるが、各管路の弁の
開閉は汚水の水質がきまればタイマより自動制御
できるものである。 The above is the mode of treatment operation, and the opening and closing of the valves of each pipeline can be automatically controlled by a timer once the quality of the waste water is determined.

部分には同一符号を付し説明を省略した。Example 2 In the case of this example shown in Figures 3 to 5, the reaction tank etc. are the same as in Example 1, but the contact material 21 is not made into granules, but instead is made of an inclined plate device with protruding ray fins or a honeycomb. The fixed precipitation separator 21a is used as a fixed contact material. Therefore, in this example, the solid-liquid separation operation using the contact material is not an overeffect, but is due to a precipitation effect. For other processing operations and effects, see Example 1.
This is the same as in Example 1, and in the figure, the same or equivalent parts as in Example 1 are denoted by the same reference numerals, and their explanations are omitted.

A plurality of biological reaction tanks 1, 1, . . . are arranged in series, and only the solid-liquid separation tank 22 is provided separately. In this case, the movement of liquid between reactors in series is due to the difference in water level. In this example as well, the same or equivalent parts as in Example 1 are denoted by the same reference numerals, and the explanation thereof is omitted.
