Abstract

The invention provides a sewage integral treatment device. The sewage integral treatment device comprises a coarse filtering tank, a heavy metal removal tank, an air floatation tank, an anaerobic tank, an anoxic tank, an aerobic tank, a precipitation tank, a fiber turntable filtering tank, a sludge reflux tank and a quartz sand filtering tank which are sequentially connected, wherein the precipitation tank is connected with the sludge reflux tank, the sludge reflux tank is respectively connected with the anaerobic tank and the sludge storage tank through pipelines, and the sludge storage tank is connected with a sludge dewatering chamber; an aeration device is arranged in the aerobic tank, the precipitation tank is connected with a dosing room, the air floatation tank comprises a PH (potential of hydrogen) conditioning tank, a PAC (powdery activated carbon) mixing tank, a PAM (polyacrylamide) mixing tank and an aeration reaction tank, and the precipitation tank comprises a tank body and a middle cylinder body. The sewage integral treatment device has the advantages that the problems of difficulty in removal of heavy metal and overstandard of effluent water suspension in the original technology are solved, and the drainage standard can be reached.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an integrated sewage treatment device. Background technique [0002] Currently with an A 2 The O-based domestic sewage treatment process mainly removes organic matter, nitrogen, phosphorus and other pollutants in water. However, once the sewage contains heavy metals and the pH is less than 5, directly use A 2 The O process will cause a devastating blow to the sludge, thereby destroying the biodegradation system and failing to meet the discharge standards. In addition, when the existing process is adopted, the suspended solids in the effluent sometimes exceed the standard. Therefore, for the raw water quality in this case, if A 2 If the O system is operating normally and the effluent reaches the standard, the raw water must be pre-treated and post-treated. Contents of the invention [0003] In view of this, the present invention aims to propose an integrated sewage...
