However, because the positions of the auxiliary flow pushing equipment and the aeration equipment are relatively fixed, the adjustment scope is limited, and the maintenance amount of the equipment is greatly increased because a large amount of flow pushing equipment is added.
The micropore aerator is fixed at the bottom of the tank, if the concentration of the influent pollutants is low or the aeration is intermittently (limitedly) for controlling the sludge concentration, the air supply is stopped, the activated sludge is deposited at the bottom of the tank and covers the aerator, the micropore blockage can be caused after a long time, the aeration resistance is increased, and even the aeration efficiency is seriously reduced, so that the aerator is frequently replaced.
At present, a submersible water impeller is often arranged at the front end of an area where aerators are distributed, so that the problem of sludge deposition on the bottom of a pool and the surface of a microporous aerator can be solved, but if the distance between the impeller and the microporous aerator is too close, the aerator is often loosened or even damaged due to too large thrust of the impeller, and the problem of blockage of the microporous aerator caused by sludge deposition cannot be thoroughly solved after the distance is too far. On the other hand, the aerobic area for arranging the microporous aerator is larger, and the more submersible water impeller is arranged, so that the investment and the operation cost are increased, the number of equipment is too much, and the maintenance and the management are inconvenient.
