伊洛河水污染现状成因分析及防治对策

Analysis of Water Pollution Causes and Prevention and Control Measures in Yiluo River

对伊洛河干流水质及排污口开展实地调查取样,并进行监测评价,结果表明:洛河水质沿程逐渐变差,上游水质较好,中下游洛阳、偃师等城市河段水质明显恶化;伊河水质整体较好,但洛阳和栾川两个局部城镇河段水质较差;污染原因主要是排污企业超标排放,生活污水未得到有效集中处理。据此,对伊洛河流域提出水污染防治对策:确立水功能区限制纳污红线,严格控制伊洛河入河污染物总量;加强工业污染源管理和控制,重点关注金属加工、电力和化工企业等污染主导行业;完善收水管网,提高生活污水处理及回用率;保证河道内留有一定的自净水量,保障河流纳污能力。

By field surveying and sampling from the main stream and sewage outlets of Yiluo River,the paper draws conclusions that the water qual-ity along the Luohe River gets bad gradually,water quality of the upstream is better,but that of the middle and lower reaches is deteriorative where big cities such as Luoyang and Yanshi are located;water quality of Yihe River overall is good,except two local urban reaches mainly in Luoyang and Luanchuan;the pollution of Yiluo River is mainly ascribed to excessive emissions of most polluting enterprises,and sewage is not processed ef-fectively. Therefore,water pollution prevention and control measures for Yiluo River are put forward as follows：establish the pollution control red line of water function zones,and strictly control the total pollutants discharged into the Yiluo River;strengthen the management and control of in-dustrial pollution sources,especially the leading industry such as metal-processing,electricity and chemical;improve the sewage collection pipe network,so that more sewage can be treated and recycled;ensure the water quantity of self-purification in the river and guarantee the river pollutant carrying capacity.
