连云港大浦污水处理厂进水数据统计和分析

Data Statistics and Analysis of Water Inflow in Lianyungang Dapu Sewage Plant

城市污水处理厂设计规模与进出水标准是决定污水处理厂的工艺类型、构筑物规模、工程投资和运行效果的重要因素.现在已建成的大部分城市污水处理厂往往因为进水负荷动态变化较大,使设计水量或水质普遍与实际运行情况有较大的差异,降低了投资效益的同时,也严重影响了运行效率.因此,对污水处理厂进水水质的历史数据进行整理,并据此得到有价值的统计和分析结果,对控制工程建设投资、降低运行和管理费用具有重要意义.对连云港大浦污水处理厂的进水特性进行分析,基于分析结果所确定的水质现状,可为该厂高效运行提供参考依据,也为新的污水厂设计提供信息.

The design scale and water inflow and outflow standard of urban sewage plants are the important factors to decide their technological types,structure scale,project investment,and operating effects.In most urban sewage plants,because of the big dynamic changes in influent load,there is considerable difference between the designed water yield or quality and the practical operating situations,which has decreased investment returns and influenced greatly the operating efficiency at the same time.Therefore,it's significant to organize the historical data of the water inflow quality,and gain valuable statistics and analysis,for the control of project construction investment and the decrease of running and managing expenses.In this paper,the water inflow characteristics in Lianyungang Dapu Sewage Plant was analysed,and based on the current water quality from this analysis,it can provide a reference for its efficient operating,and it also may offer effective information for the design of new sewage plants.
