摘要
通过对国内外河流黑臭研究方法的比较研究,对江苏省金川河、北塘河、清安河以及西盐大浦河的水质和黑臭状况监测与调查,确定了适用于江苏省的城市河流黑臭判别模型响应的指标标准。影响江苏省城市河流水质,造成水质黑臭的主要污染因子为溶解氧(DO)、氨氮(NH3-N)、高锰酸盐指数(CODMn)、五日生化需氧量(BOD5)和总磷(TP)。研究提出的综合水质标识指数法可用于江苏省城市河道黑臭情况的识别,有机物综合污染指数可用于城市河流黑臭程度的识别。江苏省城市河流黑臭评价指标标准为:综合水质标识指数≥6.5,水体发生黑臭。
Through comparative study about research method of malodorous and black rivers, after the monitoring and investigation of water quality and state of malodorous and black of Jinchuan River, Beitang River, Qingan River and Xiyandapu River in Jiangsu, the determination model and indicators were built. The main effect factors to malodorous and black rivers are DO, ammonia, CODMn, BOD5 and TP. The Method of Comprehensive Water Quality Identification Index can be used to identify whether river is malodorous and black or not. And the Organic Comprehensive Pollution Index can be used to identify whether state of malodorous and black of rivers in Jiangsu. The standard is that when CWQII（Comprehensive Water Quality Identification Index） ≥6.5,waterbody is malodorous and black.
