Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 9-141066 discloses a submerged membrane separation apparatus used in an apparatus for treating organic wastewater such as night soil. This apparatus is used by being immersed in wastewater from a treatment tank, and when the wastewater passes through a filtration membrane by the action of a suction pump, it is separated into permeated water and solid substances such as activated sludge. Since the permeated water has a low BOD value and is relatively good in water quality, it can be effectively used as water for flush toilets.

る。In the above-described apparatus, since solid substances may adhere to the filtration membrane and reduce the filtration efficiency of the membrane, bubbles generated from the air diffuser may be brought into contact with the filtration membrane, or the treatment tank may be damaged. The surface of the filtration membrane is washed by, for example, bringing the rising water stream into contact with the filtration membrane. However, if the number of air bubbles is increased or the speed of the rising water flow is increased to enhance the washing effect, the amount of water that can be filtered per unit time decreases, and in that sense, the filtering speed may decrease.

And a filter 21 including a filtration chamber 26 located above the storage container 20 and a second air diffuser 25 located below the storage container 20. The storage container 20, the filtration chamber 26, and the second air diffusion pipe 25 are surrounded by a peripheral wall 23 located on these side surfaces. The storage container 20 includes a top wall 20a and a bottom wall 20b.
And a plurality of water-permeable holes 18 communicating with the inside and outside of the container 20 are formed in the top wall 20a and the bottom wall 20b, and the side wall 21c is fixed to the peripheral wall 23 via the support shaft 30. ing.

In addition, this pellet 2
At the same time, the second, consisting only of inorganic substances without humic substances
In some cases, particles such as pellets and pumice may be put into the storage container 20.

7 and a water supply pipe 28 extending to the outside of the water storage tank 2. The filtration chamber 26 has, for example, a rectangular cross section in the horizontal direction, and is formed around the filtration membrane 26a. The pump 27 suction-filters the wastewater W in the purification unit 3 into the filtration chamber 26 and sends it out of the water storage tank 2.

1a, and a water hole 31b below. Due to the ejection of the air from the second air diffuser 25, an upward flow of the drainage W is generated inside the peripheral wall 23, and a downward flow is generated outside the peripheral wall 23. The drainage W flows into the inside of the peripheral wall 23 from the water passage hole 31b, flows out of the peripheral wall 23 from the opening 31a, and circulates inside and outside the purification unit 3.

工程へ戻されて再利用される（図２参照）。In the process of circulating the wastewater W, the wastewater W passes through the pellet storage container 20 and comes into contact with the pellets 22 under aerobic conditions, and the cultivation and activation of the soil bacteria in the wastewater W proceeds. As a result, in the wastewater W, solid substances such as activated sludge are consumed and become finer, and the viscosity of the wastewater W decreases. The waste water W is stored in the pellet storage container 2
After leaving 0, the water is filtered by the filtration membrane 26a under the suction action of the pump 27, and separated into water and solid substances having relatively low values of BOD and SS. The water is returned to the outside of the water storage tank 2 by the pump 27, for example, returned to a step before the water storage tank 2 in the wastewater treatment system and reused (see FIG. 2).

多くしたりする必要がない。In the wastewater treatment apparatus 1, the wastewater W in the water tank 2 is filtered in the purification unit 3 while receiving the active action of soil bacteria. The wastewater W is quickly filtered because the solid matter is reduced and the viscosity is reduced as compared with the case where the wastewater W is filtered without receiving such an action.
Excellent water quality with low OD and SS values. For example, both values can be 5 ppm or less. The solid substance is fine and does not easily clog the filtration membrane 26a. Even if the solid substance adheres to the surface of the filtration membrane 26a, the solid substance is removed from the filtration membrane 26a by the rising water flow flowing inside the purification unit 3 and the bubbles ejected from the second diffuser 25. Easily detached. Therefore, in the processing apparatus 1, there is no need to increase the speed of the rising water flow or increase the number of bubbles to be jetted out in order to wash the surface of the filtration membrane 26a.

In the reaction tank 56, the processing apparatus 1 and the drain pump P
2 is included. The water taken out by the pump 27 of the apparatus 1 is supplied to the outside of the process as treated water in addition to being supplied to the regulating tank 55 as reused water, and is used as water for flush toilets and water for floor cleaning. Become. In addition, drainage pump P 2
Thereby, the sludge in the reaction tank 56 is sent to the previous step as returned sludge. The process of the conventional example shown in FIG.
, A reaction tank 56, a separation tank 57, and a culture tank 58, and the drainage W moves along the arrow. In the separation tank 57,
The wastewater W is separated into treated water and solid matter through the filtration membrane, and the treated water goes out of the process. In the culture tank 58, the wastewater W comes into contact with the pellet under aerobic conditions, and the cultivation and activation of soil bacteria proceeds. As is clear from the comparison between FIGS. 2 and 3, the use of the processing apparatus 1 eliminates the need for the separation tank 57 and the culture tank 58 which were required in the past. The tank 56 is responsible. In a wastewater treatment facility using such a conventional treatment process, the area occupied by the separation tank 57 and the culture tank 58 is about 20 to 3
Since it is 0%, the area of the processing facility is reduced by 20 to 30% in the case of the process of FIG. 2 employing the present invention.
