With economic development at home,municipal wastewater and industrial wastewater emissions are increasing,due to the current wastewater treatment plants use biological treatment,the secondary effluent still contains part of the organic matter that is difficult to be biodegradable.If direct discharge without treatment,it will be a threat to the human body and the ecological environment.Secondary effluent organic matter(EfOM)is the remaining organic matter of wastewater after secondary biochemical treatment,mainly derived from natural organic matter,soluble microbial products and synthetic organic compounds.In this paper,the main components of EfOM are introduced,quantified and characterized.And then the performance and advantages and disadvantages of various deep treatment processes(i.e.,coagulation,advanced oxidation,adsorption,membrane separation)in removing EfOM are reviewed,and the removal effect is compared with a single process by the combined process,which can provide a theoretical basis for the effective removal of EfOM.
