Abstract

The invention relates to an electrochemical performance enhanced bacteria-algae membrane aeration bio-membrane reactor system and an application thereof. The system comprises an anode chamber, a cathode chamber and a separation membrane, and also comprises a membrane aeration assembly arranged in the cathode chamber, a biological cathode electrode and a biological electrode arranged in the anode chamber. The external air supply device which is connected with the membrane aeration assembly is provided with a circulating pipeline, wherein the input end of the circulating pump is connected with the top end of the reactor, and the output end of the circulating pump is connected into a water inlet pipeline for connecting the water inlet pump and the reactor; moreover, the biological anode electrode is electrically connected with the biological cathode electrode through an external circuit, and the system is used for treating ammonia-nitrogen-containing wastewater. Compared with the prior art, the system is simple in structure, adopts bubble-free aeration, is high in gas utilization rate, is low in energy consumption in the operation process, is stable in operation, has pollutant treatment and power generation functions, can recover microalgae biological energy, and has a wide application prospect in the fields of sewage treatment and recycling.

Description

technical field [0001] The invention relates to the technical fields of environmental protection, water treatment technology and equipment, in particular to a bacteria and algae membrane aerated biofilm reactor system with enhanced electrochemical performance and its application. Background technique [0002] Ammonia nitrogen wastewater has a wide range of sources, mainly in many industrial wastewater, and the discharge volume is large, such as chemical fertilizers, coking, petrochemical, pharmaceutical, food, landfills, etc. all produce a large amount of high-concentration ammonia nitrogen wastewater. Among them, the recycling wastewater of circuit boards contains high concentration of ammonia nitrogen. Ammonia nitrogen in the water body will lead to eutrophication of the water body and accelerate the proliferation of aquatic plants such as seaweed and algae, so that the ecological balance of the water body is out of balance. At the same time, water polluted by ammonia nit...
