2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 9-141066 discloses an immersion type membrane separation device used in a device for treating organic wastewater such as human waste. This device is used by immersing it in the waste water of the treatment tank, and when the waste water passes through the filtration membrane by the action of the 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 relatively good water quality, it can be effectively used as water for flush toilets and the like.

In the above apparatus, since solid substances may adhere to the filtration membrane and reduce the filtration efficiency of the membrane, air bubbles generated from the diffuser tube may be brought into contact with the filtration membrane or the treatment tank may be treated. The surface of the filtration membrane is washed by contacting the rising water flow of the membrane with the filtration membrane. However, if the number of bubbles is increased or the rate of rising water flow is increased in order to enhance the washing effect, the amount of water that can be filtered per unit time decreases, and in that sense the filtration rate may decrease.

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 cultivation and activation of soil bacteria in the wastewater W proceeds. As a result, the wastewater W consumes solid substances such as activated sludge and becomes finer, and the viscosity of the wastewater W decreases. The drainage W is used as the pellet storage container 2
When it comes out of 0, it is filtered by the filtration membrane 26a under the suction action of the pump 27, and is separated into water and solid substances having relatively low BOD and SS values. The water is returned to the outside of the water tank 2 by the pump 27, for example, returned to a step prior to the water tank 2 in the wastewater treatment system and reused (see FIG. 2).

In the waste water treatment apparatus 1, the waste water W in the water storage tank 2 is filtered in the purification unit 3 while being actively acted by soil bacteria. The wastewater W is quickly filtered because the amount of solid substances is less and the viscosity is lower than that in the case of being filtered without such an action, and the filtered water is B
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, and even if it adheres to the surface of the filtration membrane 26a, the rising water flow flowing inside the purification unit 3 and the bubbles ejected from the second air diffusing pipe 25 cause the filtration membrane 26a to escape from the filtration membrane 26a. Easily leave. Therefore, in this processing apparatus 1, it is not necessary to increase the speed of the rising water flow or increase the number of bubbles to be jetted in order to wash the surface of the filtration membrane 26a.

2 and 3 show a wastewater treatment process in which the treatment apparatus 1 is used and a conventional process to be compared with this process. The process of FIG. 2 is performed by adjusting tank 55 and reaction tank 56.
The reaction tank 56 includes a processing device 1 and a drainage pump P.
2 and are included. The water taken out by the pump 27 of the apparatus 1 is supplied to the adjustment tank 55 as reused water, and is also sent out of the process as treated water to be used as water for flush toilets, water for floor cleaning, etc. Become. In addition, drainage pump P 2
The sludge in the reaction tank 56 is sent to the previous step as return sludge. The process of the conventional example shown in FIG.
, The reaction tank 56, the separation tank 57, and the culture tank 58, and the wastewater W moves along the arrow. In the separation tank 57,
The wastewater W is separated into treated water and solid substances through the filtration membrane, and the treated water goes out of the process. In the culture tank 58, the waste water W comes into contact with the pellets under aerobic conditions, and cultivation and activation of soil bacteria proceed. 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 conventionally required, and the roles of these tanks 57, 58 are reacted. 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 was 0%, the area of the processing facility is reduced by 20 to 30% in the process of FIG. 2 adopting the present invention.
