A Simulated Experimental Research on Treating Rural Domestic Sewage through a Stabilization Pond Process

In accordance with emission characteristics and treatment situation of rural domestic sewage, this experiment studied the effect of domestic sewage treatment in rural areas through the design of a stabilization pond miniature-testing device. In the stable test operation phase, the average removal rates of COD, TP, and NH₃-N were respectively 92.53%, 97.57%, and 95.10% in an aerobic pond reactor. The average removal rates of COD, TP, and NH3-N were respectively 92.56%, 95.90%, and 95.90% in a facultative pond reactor. Sludge activity was stable. The effluent quality met the primary standard of sewage discharge requirements (GB8978-1996). A stabilization pond process had the characteristics of low investment, good treatment effect, simple operation and low maintenance cost.
