大汶河流域水污染现状及防治措施

大汶河流域的中上游有7项污染物质量浓度超标,下游有3项超标。地下水色度超出饮用水水质标准0 6倍,浑浊度超标0 8倍。由于大规模开采,深层承压水受到地表水和浅层地下水的补给,水质也有污染。因此,对流域污染提出防治措施:从源头控制污染,推行清洁生产;增建污水处理厂及配套管网;发展生态农业、加快治理面源污染;建设湿地保护区等。

Present situation of water pollution in Dawenhe River Basin and measures for pollution prevention and remediation

The concentration of 7 kinds of pollutants in the mid-upper reaches and 3 kinds of pollutants in the lower reaches of the Dawenhe River Basin exceeds the standard of water quality. Chroma and turbidity in the groundwater are 1.6 times and 1.8 times respectively of those listed in the drinking water quality standard. The over-exploited deep confined water, which is replenished by surface water and phreatic water, is also polluted. For pollution prevention and remediation, countermeasures are proposed as follows, pollution source control, clean production, construction of more sewage treatment plants and related pipe structures, ecological agriculture enhancement and non-point pollution control, protection region construction in turbid areas.
