Abstract

The invention belongs to the technical field of sewage treatment, and particularly discloses a multi-stage water body remediation system which comprises a contact oxidation tank, a stirring tank, a sedimentation tank, a sludge concentration tank and a sludge dewatering tank, wherein an aeration device is arranged at the bottom of the contact oxidation tank and connected with a nano aerator through a pipeline, a sewage outlet is formed in the bottom of the sedimentation tank, the sewage outlet is sequentially communicated with a sludge thickening tank and a sludge dewatering tank through a sewage discharging pipeline, a sludge dewatering machine is arranged in the dewatering tank, a mud cake conveying belt is arranged on the outflow side of the dewatering tank, a dynamic filtering system is arranged on the supernate outflow side of the sedimentation tank, and a static filtering system is arranged on the outflow side of the dynamic filtering system. According to the invention, all the systems cooperate with each other, the purposes of dephosphorization, denitrification and COD reduction of sewage can be achieved, and sludge discharged from the sedimentation tank can be made into mud cakes or fertilizers after being concentrated and dehydrated, so that waste utilization is achieved.

Description

technical field [0001] The application belongs to the technical field of sewage treatment, and in particular relates to a multi-stage water restoration system. Background technique [0002] With the extensive development of agricultural production activities, the sources of rural domestic sewage are becoming more and more extensive, mainly including domestic drainage of rural residents, drainage of rural folk tourism, drainage of rural livestock and poultry breeding, drainage of rural aquaculture and drainage of hotels and restaurants around rural areas, etc. , The components of pollutants in these discharged sewage are complex and diverse, mainly including total nitrogen, total phosphorus, COD, BOD and other pollutants. [0003] In the prior art, the treatment of sewage only stays in the stage of physical precipitation and flocculant removal of impurities, and cannot really play the role of sewage purification. [0004] Therefore, providing a new sewage purification syst...
