Water Pollution Control And Management Of Mulan River, Putian City

Mulan River is the largest river in Putian area, and it is the main water source for the residents. However it warns us for the water quality, eg. the water in Nanbei Yang, one of its banches, is worse than Class IV, and even Class V. This kind of water has not any usage functions, as it can endanger the residents. The main reason for the poor water quality is that water pollution control and management of Mulan River are not rational and effective, especially when it acts without scientific and technical support.In this study one-dimensional water quality model for Mulan River is developed to find more effective way of water pollution control. Further more, with the use of GIS, GPS, GE and VC++, the visualization and accurate result of this study can be achieved. We wish this study would promote water environmental research and management of Mulan River, and form one of the basic studies to realize the real-time, dynamic and visualization water environmental management in Putian City.This paper, the first chapter outlines the progress of water quality modeling research in China and overseas. In the following chapter, water quality model for Mulan River is constructed according to Quantitative Analysis method, where the scope of Pe (Peclet Number) is used to determine three-dimensional pollutant situation. In this practical one-dimensional multi-point source model, the parameters are suitably determined according to the modeling sensitive test. At the neat to last, VC++ technology enables this model and it results visualization. Above all, through this process, perhaps the result of this study can prvide scientific basis to water pollution control and management of Mulan River.Finally, some recommendations and prospects are given, such as establishing several systems for Mulan River, for example the real-time dynamic tracking system, the warning system and water quality management supporting system, etc.
