Abstract

The invention discloses an integrated built-in anaerobic membrane bioreactor including a reaction tank body and a PLC system. A homogenizing stirring blade, a circular heater, a hollow fiber membrane assembly, a liquid level controller and a temperature sensor are disposed in the reaction tank body. A water inlet pipeline, which has a water feeding peristaltic pump, and a bottom sewage draining outlet are arranged below the reaction tank body. The reaction tank body is also provided with a water outlet pipe having a water outlet peristaltic pump. The temperature sensor, the hollow fiber membrane assembly and the liquid level controller are all connected to the PLC system. The built-in anaerobic membrane bioreactor can prevent loss of excess sludge effectively and enrich microorganisms, is not liable to cause membrane contamination, can effectively recycle energy gas, has high safety, is easy to control, and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of urban domestic sewage treatment, in particular to an integrated built-in anaerobic membrane bioreactor. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] At present, the treatment method of domestic sewage in my country is mainly based on traditional aerobic biological treatment, which consumes a large amount of energy and produces residual sludge that is difficult to solve. Sludge will also cause serious secondary pollution to the environment. With the development of the concept of domestic sewage treatment as a resource, people began to re-evaluate reasonable urban domestic sewage treatment methods in order to build a reasonable and feasible urban domestic sewage treatment energy technology. Although the use of anaerobic biological technology to treat urban domestic sewage can o...
