辽河流域总面积２２８９６０ｋｍ２，由于该地区工业集中，人口稠密，大量工业废水及生活污水的排入，使河水受到严重污染。据实测，该流域控制段基本为Ⅴ—超Ⅴ类水质（地面水环境质量标准）。主要超标污染物是高锰酸盐指数、五日生化需氧量、挥发酚。防治对策是：①必须制定有针对性可操作的规划；②必须摸清流域水污染现状，即流域内污染源废污水、污染物排放的时空分布规律；③把水利工程项目与环保工程项目相结合；④把污染治理作为各级行政一把手的重要业绩进行严格考核等。
The Liaohe River Basin has a total area of 228960km2. Due to the concentration of industries and heavy population in the area, a large amount of industrial wastewater and domestic sewage are discharged into the country, causing serious pollution to the water. According to the actual measurement, the control section of the basin basically is Ⅴ-super-Ⅴ water quality (surface water environmental quality standard). The main pollutants exceeded permanganate index, five days of biochemical oxygen demand, volatile phenol. Prevention and control measures are: ① must be targeted and operational planning; ② must find out the status quo of water pollution in the basin, that is, the spatial and temporal distribution of waste water and pollutant emissions in the basin; ③ The combination of water conservancy projects and environmental projects ; ④ The pollution control as the top leaders at all levels of the important performance of strict examination.
