摘　　要：污水排放特征是评价污染负荷的依据,也是进行污水治理规划、设计建设和运行维护的基础,农村污水量的确定是污水处理设施设计、运行维护的难点之一。本研究调研了长三角地区某县306座污水处理设施2022年全年进水水量数据,探究了不同处理规模进水量的变化规律,重点讨论了春节假期、雨季等时期水量变化规律。研究结果表明,随着城镇化水平快速提高以及农村居民生活方式的改变,春节期间水量变化呈现出3类特征,水量设计应根据不同类型村庄特征进行。同时,应重视户排水系统的雨污分流,厨房、院落洗漱、厕所、洗浴污水应收尽收,减少汛期屋面及院落雨水进入收集系统。The discharge characteristics of rural sewage are the basis for evaluating pollution loads and sewage treatment planning,design,construction and maintenance.The determination of rural sewage volume is one of the difficulties in the process.The changing trends of inflow volume during spring festival holiday and rainy season were analyzed based on the 2022 annual data of 306 rural sewage treatment facilities of the Yangtze River Delta region.The research results showed that with the rapid improvement of urbanization level and the change of rural residents'lifestyle,the change of water quantity during the spring festival presented three characteristics,and the sewage quantity design should be based on the characteristics of different types of villages.At the same time,attention should be paid to the diversion of rainwater and sewage of household drainage system so as to reduce rainwater into the collection system in flood season roof and courtyard,while kitchen,courtyard washing,toilet and bathing sewage should be collected.
