摘　　要：选取上海市中心城区白龙港片区为研究对象,通过收集该片区末端污水处理厂2021年实际运行数据,系统分析了该片区各污染物的水质特征、概率分布和相关关系,以及不同特征天各污染物的水质特征和营养比例之间的关系。结果表明,该片区2021年实际进水水质低于设计值,建议进一步对白龙港片区开展管网提质增效,逐步提高片区污水厂进水浓度;该片区旱天进水各污染物浓度均值高于雨天,雨季6月—9月进水浓度基本低于其他月份;各指标周末和非周末进水浓度整体偏差较小,各指标节假日进水浓度均低于非节假日进水浓度。通过对该年度的数据进行统计分析,研究结果对指导片区污水处理厂精细化运行和工艺优化调度具有积极意义。Bailonggang district in the central districts of Shanghai as the research object was selected in this paper,by collecting the actual operation data of the end wastewater treatment plant(WWTP)in this area in 2021,the water quality characteristics,probability distribution and correlation of each pollutant in this area were systematically analyzed,as well as the relationship between the water quality characteristics and nutrient ratio of each pollutant in different characteristic days.The results showed that the actual influent water quality of this area in 2021 was lower than the design value.It was suggested to further improve the quality and efficiency of the pipe network in Bailonggang area,and gradually improve the influent concentration of the WWTP in this area.The influent concentration of each pollutant in dry days was higher than that in rainy days,and the influent concentration from June to September in rainy season was basically lower than that in other months.The overall deviation of influent concentration of each index on weekends and non-weekends was small,and the influent concentration of each index on holidays was lower than that on non-holidays.Through the statistical analysis of the annual data,the results can be used to guide the fine operation and process optimization of the regional WWTP.
