Abstract

The invention discloses a sewage treatment, regeneration and reuse system and a method for treating sewage by using the system. The system comprises a pretreatment water collecting tank, an anoxic tank, an anaerobic tank, an aerobic membrane tank and a disinfection tank, wherein partition plates extending upwards from the bottoms are arranged in the anoxic tank and the anaerobic tank, an MBR membrane assembly is arranged in the aerobic membrane tank, the pretreatment water collecting tank is connected with the water inlet of the anoxic tank through a pump, the aerobic membrane tank is connected with the disinfection tank through a membrane suction pump, a gas stripping reflux pipe is arranged at the bottom of the aerobic membrane tank, the aerobic membrane tank is connected to the water inlet of the anoxic tank through the gas stripping reflux pipe, the sewage treatment, regeneration and reuse system further comprises an air supply device, and the air supply device is connected with the MBR membrane assembly and the gas stripping reflux pipe through pipelines. The system is high in sewage treatment efficiency, low in energy consumption, simple and convenient to operate and stable in effect.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage treatment regeneration and reuse system and a sewage treatment method using the system. Background technique [0002] Urban sewage contains a large amount of organic matter, nitrate, sludge, floating matter and other impurities. The generation and discharge of a large amount of sewage not only seriously pollutes the natural environment, brings health risks, but also wastes precious water resources. Urban sewage recycling can not only effectively reduce the pressure of sewage discharge on the ecological environment, but also an effective way to alleviate the shortage of regional water resources. [0003] In the prior art, for the treatment of urban sewage, it is necessary to successively set up pretreatment sump, anaerobic pool, anoxic pool, aerobic pool, secondary sedimentation pool, filter pool, disinfection pool, etc. Disadvantages such as large area, high ...
