摘　　要：在国家“绿色发展、乡村振兴”的农村发展号召下,为了解决农村污水处理和循环利用,我们设计了基于AO处理工艺的简约型村域污水处理系统。该系统具有占地少、建造和运行成本低、处理效果好的特点。通过中国农业大学曲周实验站的实际案例,该系统运行一年后,总磷、氨氮去除率分别达到了50%和93%。污水COD含量由约700 mg/L降低到16 mg/L,去除率98%,达到我国农田灌溉水的标准(GB5084-2005),处理后水可以直接用于农田灌溉用水。曲周实验站的实际应用案例还表明,鱼类完全可以在处理后的污水中长期存活,证明了本系统的处理效果。本系统值得在我国农村推广应用。Under the country’s rural development call of “green development, rural revitalization”, in order to solve the problem of rural sewage treatment and recycling, we designed a simple village sewage treatment system based on AO treatment process. The system has the characteristics of small area, low construction and operation cost and good processing effect. Through the actual case of Quzhou Experimental Station of China Agricultural University, the removal rate of total phosphorus and ammonia nitrogen reached 50% and 93% respectively after one year of operation of the system. The COD content of wastewater is reduced from about 700 mg/L to 16 mg/L, and the removal rate is 98%, reaching the standard of farmland irrigation water (GB5084-2005). The treated water can be directly used for farmland irrigation water. The practical application case of Quzhou experimental station also shows that fish can survive in the treated sewage for a long time, which proves the treatment effect of this system. This system is worth popularizing and applying in countryside of our country.
