Abstract:
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 m3/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/A2O, biological contact oxidation and AO/A2O+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.
