苍溪县工业园水环境评价及污染防治对策

Water Environment Evaluation and Pollution Control in Industrial Park of Cangxi County

水环境评价和预测是水资源规划管理的重要内容之一,对促进水资源可持续利用具有重要现实意义。以苍溪县工业园地表水环境监测数据为基础,应用单项标准污染指数法对跌马桥沟地表水环境的影响进行评价,并采用完全混合模型和一维稳态水质模型相结合的方法对排污口下游的地表水进行预测;最后对结果进行了初步分析,并提出了相应的污染防治对策,以期为制定水环境宏观决策及区域经济发展规划提供必要的科学依据。

As the important part of water resource planning and management, water environment evaluation and forecast are of vital realistic significance to promote sustainable utilization of water resources. Using the data derived from the surface water environment monitoring of industrial park in Cangxi County, surface wa- ter environment evaluation of Diemagou River is made by applying the method of single standard pollution in- dex. Then, the method combining complete mixing model with one-dimensional water quality model is applied to carry on surface water environment prediction in the downstream of sewage outfall of Diemaqiao Riv- er. The result of evaluation and prediction is analyzed preliminarily. At last, corresponding countermeasures for prevention and control of water pollution are presented to provide an essential scientific basis for making macro-policies of water environment and a regional economic development plan.
