存在安全隐患的水源不宜作为城市备用水源地——以德阳市城市备用水源射水河为例

Unsafe Water Sources Should Not Be Used As an Alternate Water Source of City——Sheshui river of DengYang as Alternate Water Source as an Example

通过对四川省德阳市射水河流域的现场勘测和水质监测,发现射水河流域水质主要受到畜禽养殖废水、城镇生活及农村污水和垃圾、工业废水及农村面源的污染。射水河流域支流多、人口密度大、保护难度大以及对污染源的有效治理难度大,因此存在的安全隐患太多。射水河流域在未解决上述安全隐患的前提下,不宜作为饮用水源地。

Through field survey and water quality monitoring on Sheshui river of Deyang, we found that water quality of Sheshui river is mainly influenced by livestock, poultry breeding wastewater, urban life, rural sewage, garbage, industrial waste water and rural non-point source pollution. There are many tributaries in Sheshui river, population density, difficult to protect, difficult to effective governance of the pollution, so there are too many safety problems. Before solving the safety hidden trouble, Sheshui river should not be as drinking water source of Deyang city.
