苏州河水的黑臭现象研究

通过对苏州河上海段３００ｋｍ＾２水域范围的实际观测试验，研究了苏州河出现黑臭现象的规律。讨论了河流中的有机污染物（ＣＯＤ、ＢＯＤ、ＮＨ３－Ｎ），溶解氧和水温对河水黑臭的影响定量关系，并应用多因子系数，建立了水质黑臭指数关系式，经过实测进行了验证，结果表明，应用所建立的黑臭指数关系式对苏州河沿程水质进行评价，其正确率可达９７％。

Study of the Phenomena of Water Blackening and Stink on Suzhou Creek

Phenomena of blackening and stink in urban river water were studied through analysis of the water in Suzhou Creek, Shanghai. Environmental factors: COD, NH_3-N, DO and water temperature were proposed as odorous thresholds, then blackening and stink indexes were established with the parameters of multifactor. The accuracy was 97% with the established index model, through verifying a series of observed data of the river in Shanghai.
