Abstract

The invention provides an anaerobic ex-situ electro-release iron membrane bioreactor sewage advanced treatment and resource recovery system and a method thereof. The system comprises an electrolytic anaerobic biological reaction unit and a membrane separation unit, wherein a water inlet and a water outlet are formed in the electrolytic anaerobic biological reaction unit; wherein a water inlet of the electrolytic anaerobic biological reaction unit is connected with a sewage draining exit, a water outlet of the electrolytic anaerobic biological reaction unit is connected with the water inlet ofthe membrane separation unit, the membrane separation unit is provided with a clean water outlet and a sludge outlet, and the sludge outlet is connected with the water inlet of the electrolytic anaerobic biological reaction unit; the electrolytic anaerobic biological reaction unit is also provided with a sludge discharge port; the electrolytic anaerobic biological reaction unit is used for carrying out electrochemical degradation and anaerobic biological degradation on the wastewater; the membrane separation unit is used for carrying out aerobic biodegradation on the wastewater, dissolving phosphate and carrying out flocculent precipitation on colloidal particles and suspended particles causing membrane pollution; the method has the advantages of convenience and flexibility in operation, high treatment efficiency, good effluent quality, small occupied area, low energy consumption, high energy recovery rate and the like.

Description

technical field [0001] The invention relates to the technical field of advanced sewage treatment and membrane pollution control of membrane bioreactor (MBR), and also includes resource recovery and utilization technology, and more specifically relates to an anaerobic heterotopic electrolysis iron film bioreaction for low-concentration organic wastewater A system and method for advanced treatment and resource recovery of device sewage. Background technique [0002] With the improvement of living standards, everyone attaches great importance to water treatment. Anaerobic membrane bioreactors have been widely concerned because of their advantages such as low energy consumption, small footprint, high energy recovery rate, and good effluent quality. However, membrane fouling is An important reason that restricts the further development of this technology and is difficult to put into use in large quantities is that a large amount of energy and chemicals are consumed in the process...
