设计进水水质水量是城镇污水处理厂工艺流程选择、工程设计最为基础、最为重要的数据，其计算不当会给城镇污水处理厂的建设和运行管理带来不良影响。调查了贵州省已建98座城镇污水处理厂2012年运行情况，结果表明：基于规划面积、人口和工业发展的预测及其生活污水量、工业废水量和公建、商业设施污水量所占比例计算的设计进水污水量和污染物浓度往往偏差较大，设计进水水量和水质普遍较实际进水偏高，设计进水BOD／COD、BOD5／TN与实际情况脱节，并给已建城镇污水处理厂的运行管理带来了一些困难。

The data of water quality and quantity of municipal sewage treatment plants play an important role in engineering design.It will do harm to the operation and management of plants if the calculation is improper. Survey in 2012 shows that based on planning area,population,industrial development,and the proportion of domestic sewage,industrial wastewater and sewage flow of public buildings and commercial facilities,the calcu-lation of water quantity design and pollutant concentration often has large deviation.The design quantity and in-fluent quality are higher than the actual ones.Design of influent BOD/COD and BOD5/TN is divorced from the actual situation.They are the difficulties to the plants which have been built.
