项目摘要

The Water quality and quantity whish is used in urban activities was examined. The water used at home was analyzed in terms of expansion and development of water use appliance. The quantity and quality of water which required for domestic and urban use were studied. On the basis of the balance of water quality and quantity between demand and discharge, water reuse potetial was examined.Rain water is also one of the sources of waste water. The runoff water at the beginning of rainfall is contaminated because it flush out the settled waste on the surface of road and roof. The water quality of rain water was studied. The use of the storage facility of storm water in order to reduce contaminated rain water runoff was considered. The operation methodology of storm water storage system for the control of flood and contaminated rain water discharge was discussed.The methodology of waste water treatment system planning in a small area was studied. There are two types of system ; one is sewerage system and the other is on-site treatment system. The cost of those systems was investigated in terms of population and area.The multi purpose dams were constructed for the control of flood and draft. The group of dams in a watershed is a complicated system and its operation is very important and difficult. Method to solve dam operation problem was studied.

对城市生活用水的水质和水量进行了检测。从用水器具的扩大和发展两个方面对家庭用水进行了分析。研究了生活用水和城市用水的水量和水质。在水量和水质平衡的基础上，分析了雨水回用的潜力，指出雨水也是污水的来源之一。降雨初期的径流水，由于冲刷路面和屋顶上的沉降垃圾，造成污染。对雨水水质进行了研究。考虑使用雨水储存设施，以减少受污染的雨水径流。探讨了用于控制洪水和污染雨水排放的雨水调蓄系统的运行方法，研究了小区域污水处理系统的规划方法。有两种类型的系统;一种是污水系统，另一种是现场处理系统。这些系统的成本从人口和面积两个方面进行了调查。多用途大坝的建设是为了控制洪水和吃水。流域坝群是一个复杂的系统，其调度是流域管理的重点和难点。研究了大坝调度问题的求解方法。
