Abstract

Abstract

In view of the current hot spots of rural domestic sewage treatment, the effect of applying autonomous breathing ecological filter technology to treat rural domestic sewage under pilot scale test conditions was studied. The results showed that the technology had a good removal effect on COD, TN, NH₃-N, TP and SS, and their average removal rates were (79.22±4.28)%, (66.13±6.58)%, (84.25±4.87)%,(94.23±0.67)% and (89.07±1.35)%, respectively. The main indicators could stably reach the class A standard of Discharge Standard of Pollutants for Urban Sewage Treatment Plants (GB 18918-2002). The process design of layered packing, autonomous breathing system and intermittent operation mode were coupled with each other, and eventualy improve the treatment effect of the system.
