Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a modular sewage treatment and reclamation method and device. The device is in an integrated box structure and comprises a box body, wherein the box body is sequentially provided with a pre-precipitation chamber, a pre-dephosphorization coagulative precipitation chamber, a denitrification biological chamber, a combined nitration reaction chamber and a disinfection chamber from left to right; and the side of the box body is provided with a sludge treatment chamber. The device can perform sewage treatment and effluent water reclamation to achieve the sewage discharge indexes. The sludge generated by sewage treatment is concentrated, dehydrated and transported outside. The method and device are mainly used for integrated treatment of minitype sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a method and device for modular sewage treatment and reuse. Background technique [0002] Since urban sewage treatment has been fully promoted from key cities to prefectures, county-level cities, county towns and towns, the sewage treatment system has changed from large-scale centralized to small and medium-sized decentralized, forming a "large-scale main, small and medium-sized complementary" This is in line with my country's national conditions and development situation. This provides a new opportunity for the application and development of modular integrated sewage treatment devices. At present, the small and medium-sized sewage treatment devices on the market directly adopt the reduced version of the traditional activated sludge process. The treatment process includes: regulating tank → grit chamber → aerobic tank → secondary sedimentation tank → water outlet, etc., ...
