摘　　要：《“十四五”城镇污水处理及资源化利用发展规划》对污水处理的布局提出明确要求,但乡镇和社区生活污水处理站因生活污水进水水质指标的变化导致传统处理工艺运行效果欠佳。针对某乡镇生活污水低COD、低C/N比的特点和TN达标难的现状,采取更换鼓风机、优化构建物功能、改造沉淀,进行了工艺改造,经过35d的调试,结果表明,在进水COD为73.6~112.5 mg·L^(-1)、C/N比2~3的情况下,改造后的工艺具有污染物去除能力强、无需投加碳源、运行费用低等优势,出水主要指标优于《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。The"14th Five Year Plan for the Development of Urban Sewage Treatment and Resource Utilization"has put forward clear requirements for the layout of sewage treatment,but the traditional treatment process is not effective due to changes in the water quality indicators of domestic sewage inflow in towns and communities.In view of the characteristics of low COD and low C/N ratio of domestic sewage in a township and the current situation of difficult TN standard,the process of the original sewage treatment station was reformed on the basis of field test research.After 35d debugging and stable operation,the relevant indexes of water inlet and outlet in each process section were tested and analyzed.The results show that under the condition of influent COD of 73.6~112.5 mg·L^(-1)and C/N ratio of 2~3,the modified process has the advantages of strong pollutant removal ability,no need to add carbon source and low operating cost,and the main index of effluent is superior to the first-class A standard of Pollutant Discharge Standard for Urban Sewage Treatment Plants(GB18918-2002).
