摘要
通过踏查法对常德市河流、池塘、水库和地下水进行随机抽样调查,采用样方法对常德市水体的透明度、p H值、电导、浊度、溶解氧、总磷、总氮、化学耗氧量、五日生化需氧量等水质进行取样检测,对造成水体污染的主要因素进行了分析,并在此基础上提出了水体污染防治对策建议。调查结果表明:全市34%的河流水体受到污染,83%的池塘水体受到污染,5%的水库受到污染,地下水没有发现异常。造成常德市水体污染的主要因素包括工业污染、养殖污染、农业生产品污染、生活污水污染、医用废弃品污染以及尾矿污染。污染水体水质检测结果表明:水体p H值升高、水体透明度减小,浊度增加,电导增加,总氮、总磷含量较高,水中溶解氧含量降低,化学耗氧量、生化需氧量升高。
The pollution situation of water resource were be investigated in Changde City.The rivers,ponds,reservoirs and groundwater were randomly sampled by survey method,and the main water quality parameters of SD,pH value,Conductivity,Turbidity,DO,T-P,T-N,COD and BOD were studied by sample method.The main factors causing water pollution were analyzed,and the countermeasures of water pollution control were put forward.The results show that there was34%of the rivers and83%of the ponds and5%of reservoirs were polluted,and there was no pollution of the groundwater in Changde City.The main factors that cause the water pollution in Changde City were industrial pollution,aquaculture pollution,rural pollution from non-point,rural sewage pollution,medical waste pollution,contaminated by abandoned tailings.The testing results of quality in polluted water show that the pH was elevated and the SD was decreased and the Conductivity was elevated and the Turbidity was elevated,and the T-P and T-N was higher and the DO was decreased and the COD and BOD was increased.
