集中式饮用水源水质污染富营养化控制方法研究

Centralized Drinking Water Source Water Pollution Eutrophication Control Method

提出集中式饮用水源水质污染富营养化控制方法,选用浑浊度、叶绿素a、化学需氧量、总氮和总磷作为水质污染富营养化评价指标,并构建水质污染富营养化评价指标的隶属度函数,结合主观因素和粗糙集简约计算评价指标对应的权重,实现集中式饮用水源水质污染富营养化程度的评价。根据评价结果通过面源控制措施、建设集中式水源的污水处理系统、水体保持工作、疏浚水源底泥、水源良性生态平衡以及相关措施实现集中式饮用水源水质污染富营养化的控制。

When the current method is used to control the eutrophication of water pollution,the eutrophication degree of water source water pollution cannot be accurately evaluated,and the control effect obtained is poor.A centralized drinking water source water pollution eutrophication control method was proposed.Turbidity,chlorophyll a,chemical oxygen demand,total nitrogen and total phosphorus were selected as indicators for water quality pollution eutrophication,and water quality pollution eutrophication evaluation indicators were constructed.The membership function,combined with the subjective factors and the rough set to calculate the weight corresponding to the evaluation index,to achieve the evaluation of the eutrophication degree of centralized drinking water source water pollution.According to the evaluation results,through the non-point source control measures,the construction of centralized water source sewage treatment system,water body maintenance work,dredged water source sediment,water source benign ecological balance and related measures to achieve centralized drinking water source water pollution eutrophication control.
