Special integrated sewage treatment system for plateau and alpine regions and sewage treatment method adopting special integrated sewage treatment system

Abstract

The invention discloses a special integrated sewage treatment system for plateau and alpine regions. The special integrated sewage treatment system comprises a biochemical bin, a precipitation bin and a clear water bin which are communicated sequentially, wherein a heating coil and an aerator are arranged in the biochemical bin, the heating coil is sequentially connected with a hot water circulating pump and a thermal insulation water tank, the aerator is connected with fans, the fans, the hot water circulating pump and the thermal insulation water tank are all located in a thermal insulation fan room, and a solar heat collecting device is arranged on the thermal insulation fan room. A method for sewage treatment by using the special integrated sewage treatment system for plateau and alpine regions comprises steps as follows: S1, sewage enters the biochemical bin from a water inlet of the biochemical bin and is heated; S2, the heated sewage is precipitated in the precipitation bin, and clear water is obtained; S3, the clear water flows into the clear water bin and then is discharged. The special integrated sewage treatment system for plateau and alpine regions can operate at the low temperature in winter in the plateau and alpine regions. By means of the method for sewage treatment by using the special integrated sewage treatment system for plateau and alpine regions, the sewage treatment capability is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of water pollution control, and in particular relates to a special integrated sewage treatment system for plateau alpine, and also relates to a sewage treatment method using the special integrated sewage treatment system for plateau alpine. Background technique [0002] The existing domestic sewage treatment often adopts the general form of integrated sewage treatment equipment, that is, the standard model WSZ series sewage treatment equipment recommended by the water supply and drainage manual, which uses the biological contact oxidation method to decompose and remove the pollutants in the sewage, and then discharge it into clean water The warehouse is then discharged. Due to the low winter temperature in the alpine region of the Northwest Plateau, it is difficult for the small integrated underground sewage treatment equipment to ensure the normal temperature of the biochemical reaction due to the drop in w...
