Research on Rural Domestic Wastewater Treatment under Improved AAO Process
Rural domestic sewage treatment is a key technical challenge for achieving rural revitalization and water environment protection.By improving the AAO process,the efficiency and stability of rural sewage treatment can be enhanced,especially in the removal of key pollutant indicators such as COD,ammonia nitrogen,and total phosphorus.Design an AAO process improvement plan and evaluate the treatment effect on a laboratory scale.The results showed that the improved AAO process can stably control the COD concentration below 30 mg/L,and reduce the concentrations of ammonia nitrogen and total phosphorus to below 5 mg/L and 1 mg/L,respectively,which are better than the current rural sewage treatment standards.This result validates the effectiveness of improving the AAO process in enhancing sewage treatment performance,providing strong technical support for rural water environment management.
