合理规划的城市污水处理厂上游汇水区应是城市水污染控制的基本功能分区单元。本论文正是选取这一区域单元作为研究对象，从系统分析城市污水处理开始,对工业废水的厂内预处理规划 污染源治理与城市污水处理厂处理的优化组合、污水处理收费及污水处理企业化等问题进行重点研究，提出了一整套解决城市污水处理厂上游工业废水集中处理这一问题的技术经济方案。在研究过程中充分应用了系统分析边际费用分析、多目标规划及总量削减优化分配技术等方法和思想。并选取天津纪庄子污水处理厂上游汇水区为实例,研究并证实这一套技术经济方案的可行性 这些研究对工业废水的处理方案的评价和选取，城市污水处理厂的正确设计和优化,城市排水管理,污水处理企业化提供了科学的依据和方法。

Reasonable Upper Reaches of Municipal Wastewater Treatmeat Plant (URMWTP) should be a basic functional unit of controlling municipal water pollution. This paper selects this unit as a reseach object. It starts from analysing characteristics of municipal wastewater treatment system, studies pretreat planning in factories A Optimum Combination between pollution souces control and treatment of municipal wastewater treatment ^ wastewater treatment charge and wastewater— treatment—enterprization etc. It put forward a whole series of technological— economical scheme to solve municipal industry wastewater pollution’s problem inURMWTP. During this reseach system analysis method, marginal cost analysis method multiobject planning method and total emission control of pollutant dischage are fully applied. Finally, this paper selects Tianjin municipal Jizhangzi wastewater treatment plant as a case and demonstrates that this technological —economical scheme is feasible. It is important in theory study and practice of solving industrial wastewater pollution problem.
