改进AAO工艺下的农村生活污水处理研究

Research on Rural Domestic Wastewater Treatment under Improved AAO Process

农村生活污水处理是实现乡村振兴和水环境保护的关键技术难题。通过改进AAO工艺,可以提高农村污水处理的效率和稳定性,特别是关键污染物指标COD、氨氮和总磷的去除率。设计AAO工艺改进方案,并对实验室规模的处理效果进行评估。结果显示,改进后的AAO工艺能够将COD质量浓度稳定控制在30 mg/L以下,氨氮和总磷的质量浓度分别降至5 mg/L和1 mg/L以下,均优于现行农村污水处理标准。这一结果验证了改进AAO工艺在提升污水处理性能方面的有效性,为农村水环境管理提供了有力的技术支撑。

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.
