摘　　要：长江流域村镇污水治理是长江大保护的重要方面。收集了湖南和江西两省2017年—2021年处理规模<500 m^(3)/d的村镇污水处理工程的项目资料,从收集方式、处理技术和运维管理等三个方面,分析了两省村镇污水处理模式的应用现状。结果表明,两省村镇污水主要为单村和联村相对集中收集方式;处理设施应用中生物工艺占比最高(46.5%),其次是生物+生态组合工艺(35.16%),生态工艺应用比例最低(18.34%),其中一体化设施主要采用AO/A^(2)O、生物接触氧化和AO/A^(2)O+MBR等生物处理技术;处理设施的运维管理主要有农户、政府事业单位和第三方公司运维三种方式。研究结果可为长江中游湖南和江西两省村镇污水处理模式选择提供参考。Village and town sewage treatment in the Yangtze River basin is an important aspect of the great protection of the Yangtze River.We collected the project information of village and town sewage treatment in Hunan Province and Jiangxi Province with treatment scale<500 m^(3)/d from 2017 to 2021.The current situation of the application of village and town sewage treatment mode in the two provinces is analyzed from three aspects:collection method,treatment technology and operation and maintenance management.The collection mode of village and town sewage treatment in the two provinces is mainly single‑village and co‑village relatively centralized collection.Among the treatment facilities,the application of biological technology accounted for the highest proportion(46.5%),followed by the biological+ecological combination process(35.16%),and the application of ecological technology accounted for the lowest proportion(18.34%).The integrated facilities mainly adopt biological treatment technologies such as AO/A^(2)O,biological contact oxidation and AO/A^(2)O+MBR.The operation and maintenance management of treatment facilities mainly includes three modes:farmers,government institutions and third‑party companies.The research results can provide a reference for the selection of village and town sewage treatment modes in Hunan Province and Jiangxi Province in the middle reaches of the Yangtze River.
