辽宁太子河水污染问题的成因与对策

对辽宁太子河主要河段连续 10年 (1991～ 2 0 0 0年 )枯、丰水期河道水质变化情况进行对比分析 ,结果表明太子河流域水质呈下降趋势 ,主要超标污染物为CODMn,BOD5,NH3 N ,挥发酚等 ,导致流域水环境质量恶化的原因是流域内工业废水和生活污水的大量排放。指出要防治太子河水污染 ,必须进一步完善水资源管理体制 ,制定水资源保护规划并建立水资源核算和评价指标体系 ,建设城市污水处理系统 ,实施清洁生产 ,建立水资源实时监控优化配置系统。

Causes of Water Pollution of Taizihe River in Liaoning Province and Countermeasures

A comparative analysis is performed of 10 years' (1991～2000) variation of the channel water quality of the main sections of the Taizihe River during high water periods and drought periods. The results show that the water quality of the river basin has declined, that the main pollutants are COD Mn , BOD 5, NH 3 N, volatile phenol, and so on, and that large amounts of industrial wastewater and domestic sewage discharged into the river causes the deterioration of water environment in the river basin. Finally, some countermeasures are proposed for prevention of water pollution, such as improvement of the water resources management system, planning for water resources protection, development of a checking and estimation index system for water resources, development of urban wastewater treatment systems, and development of a real time monitoring and optimal allocation system for water resources.
