城镇黑臭河道评价与整治研究

Study on the evaluation and regulation of black and odorous rivers

为了对黑臭河道进行整治,以黑臭河道的形成原因以及黑臭机理为理论基础,以江苏省大丰区某城镇河道为研究对象,运用单项污染指数模型与综合水质标识指数法等评价方法,对该城镇黑臭河道进行评价,通过感官评判与定量指标相结合以及与评价计算结果的综合分析,确定了该城镇黑臭河道段数与长度,并以此为依据制定了相应的整治措施,最终形成一套黑臭河道评判与整治的方案,以期为类似情况的城镇河道提供借鉴。

In order to rectify the black-odor river course,the formation reason and mechanism of the black-odor river course was taken as the theoretical basis.A town river course in Dafeng District of Jiangsu Province was taken as the research object,the single pollution index model and comprehensive water quality identification index method were used to evaluate the black-odor river course in this town,and combined sensory evaluation with quantitative index and evaluation results,the number and mileage of the black and odorous rivers in the town were determined,and the corresponding regulation measures were formulated based on the comprehensive analysis.Finally,a set of schemes for the evaluation and regulation of the black and odorous rivers were formed,with a view to providing reference for similar urban rivers.
