| titleOfInvention | Sewage purification and reuse treatment method and system device |
| abstract | The invention relates to the technical field of sewage advanced treatment, in particular to a sewage purification and recycling treatment method and a system device. The system device comprises a sewage purification and reuse treatment device, an ecological treatment tank and a treated tail water storage and reuse tank, wherein the sewage purification and reuse treatment device is fixed by a support frame, one end of the sewage purification and reuse treatment device is provided with a hollow cover, and the other end of the sewage purification and reuse treatment device is inserted into the ecological treatment tank; a cavity is arranged in the hollow cover and is communicated with one end of a return pipe, the other end of the return pipe is inserted into a treated tail water storage and reuse pool, and a pump is arranged on the return pipe; the inside of the supporting frame is sequentially provided with a pre-filtering unit, a fault seepage reoxygenation unit and an ecological ditch from top to bottom, and the ecological ditch is arranged in the treatment pool. According to the invention, through the alternate action of the air fault reoxygenation area and the bacterium-algae ball filling seepage denitrification area among the filter materials, the dissolved oxygen in water is increased, and the water is further purified by the ecological ditch, so that a new bacterium-algae symbiotic high-oxygen multi-way denitrification technology is created, and further the deep treatment and the cyclic utilization of aquaculture sewage or domestic and industrial and agricultural sewage are realized. |
