【Abstract】 Catalytic iron internal electrolysis coupled biological phosphorus removal can effectively solve the problems of low efficiency of biological phosphorus removal, large dosage of chemical phosphorus removal and difficult process control. It has a broad application prospect. This paper introduces the mechanism of phosphorus removal by catalytic iron internal electrolysis coupled with biological method, emphatically analyzes the influence of three coupling modes of catalytic iron internal electrolysis and biological method on phosphorus removal effect, and points out that the biological preprocessing has a strong ability to resist impact load and can simultaneously realize phosphorus removal, reduce biological toxicity and improve the biodegradability of wastewater. In the biological built-in process, the catalytic iron internal electrolysis filler as the biological carrier greatly improves the number and activity of microorganisms, highlights the electrochemical high-efficiency phosphorus removal, and strengthens the biological nitrogen and phosphorus removal capacity. The biological post processing can effectively slow down the fouling on the surface of packing but it is rarely concerned because of its effluent chromaticity. It is concluded that new materials for catalytic iron internal electrolysis and their coupling process with biological method are still the main research direction in the future.更多还原
