| titleOfInvention | sewage disposal apparatus for nature frendly contact-rotation |
| abstract | The present invention relates to a nature-friendly contact circulation sewage treatment apparatus using a fixed bed microbial contact filter, gravel, aggregate, sand, and plants, and to a fixed bed microbial contact filter and an aeration of a contact oxidation tank. By maximizing the dissolved oxygen by the device, the BOD of the sewage is purified to about 20 ~ 30ppm, and the treated water is distributed evenly through the multi-distribution perforated pipes to the plant filter tank to the part of the multiple tanks separated by the separating partition walls. By selectively supplying, each tank has a difference in the degree of anaerobic and aerobic conditions, and a difference in the degree of anaerobic and aerobic conditions at the top and bottom of a single tank is generated. Under conditions, the absorption of plants and the decomposition and oxidation by soil microorganisms occur, It absorbs and purifies phosphorus, and induces denitrification to occur under anoxic conditions in the middle aggregate layer underneath, so that anaerobic conditions can be induced in the gravel layer underneath, and recycles sludge that can accumulate inside. By recirculating to the contact oxidation tank by using to increase the resilience of the plant filter layer, it can be continuously processed without interruption of operation, thereby reducing the management and maintenance costs. |
