ADVANCED TREATMENT DEVICE FOR FOUL WATER OF MIDDLE.SMALL SIZE VILLAGE BY USING A MEDIA

摘要

The present invention has been written, the conventional sewage treatment apparatus according to. A small town sewage high processing apparatus of using a medium can be an organic material processing of a certain concentration, but nitrogen (TN) and a lot of (TP) removal in a well designed operating costs there is a problem that it takes.; The purpose of this invention is water tank 110, a flow rate-adjusting tank 120, an aeration tank 130, the sedimentation tank 140, a filtration tank 150, the flow rate-adjusting tank when configuring the processing device of the O / wastewater to package and discharge tank (160) 120 between the forming media 172 is stacked microbial growth tank 170 within one side, and the flow rate-adjusting tank 120 and an aeration tank (130) and install the anaerobic tank 180 and the anoxic tank 190, the aeration tank 130 was laminated to media 132 into, also between the aeration tank 130 and settling tank 140, and install the circulation water tank 200 for re-supplying the treated part in the anoxic tank 190, the filtration tank 150, as a to be filled with a medium (152) for microorganism incubation and conveying the reverse wash of the filtration tank 150 to the aeration tank 130, the present invention is to give to change the water flow diagram by stacking a large amount of media in a microbial growth tank and the aeration tank and a filtration tank influx quantity can be stably cultured microbial growth and changes in water quality changes Since the entire system excellent in nitrogen and phosphorus removal efficiencies will have highly processable on low cost.
