Abstract

The invention relates to a sewage treatment and water quality early warning method of a microbial fuel cell coupling membrane bioreactor. When a specific sewage treatment and water quality early warning device is used, anaerobic sludge is inoculated to an anode chamber, aerobic sludge is inoculated to a cathode chamber, sludge concentration is 4000-12000mg / L, the hydraulic retention time of the anode chamber is 5-10 hours, the volume load of the anode chamber is 0.05-1kg COD (chemical oxygen demand) / (m<3>*d), the device continuously runs for a period of time, microorganisms in the anode chamber and the cathode chamber are stably generated on surfaces of electrodes, and then sewage is led into the device and treated. The sewage treatment and water quality early warning method can effectively solve the problems of low electricity generation and serious MBR (membrane bioreactor) membrane pollution of the device, and makes full use of electric energy generated by the device.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a method for sewage treatment and water quality early warning of a microbial fuel cell coupled membrane bioreactor. Background technique [0002] Microbial fuel cell (MFC) is a new technology that converts chemical energy into electrical energy with microorganisms as catalysts. Due to its mild operating conditions and no need for energy input, it has attracted extensive attention from academia and industry, and has been gradually applied in the field of sewage treatment to realize the resource utilization of wastewater. The basic principle of MFC is: microorganisms on the surface of the anode use organic matter in sewage (such as glucose, polysaccharides and acetic acid, etc.) to produce carbon dioxide, protons and electrons; electrons are transferred to the anode indirectly or directly to the cathode through an external circuit; protons migrate through the solution Pass through ...
