【摘要】 为了探索汾江河流水体黑臭与水质化学特征的关系 ,初步测定了汾江河水质中 p H值、氧化 -还原电位( V)、溶解氧 ( DO)、化学耗氧量 ( COD)、总氮、氨氮、硫化物 ( S2 -)、气相硫化氢 ( H2 S)、生化需氧量 ( BOD5)、嗅阈值、有机酸、有机碱等与水质黑臭有关的项目 ,分析了 DO与河水发生恶臭的组合关系 ,提出恶臭指数为客观衡量恶臭程度和状况提供了一个定量依据。更多还原

【Abstract】 Fenjiang River is a typical heavily organically polluted river in Foshan city .In order to get a clear understanding of the chemical characteristic of blackening and oder in Fenjiang River, some water quality indexes which relate to blackening and oder, such as NH 3,En,H 2S,Organic acid and Oder threshold were monitored and determined. The relation between DO and oder is analysed and the oder index PI is put forward.All the research can furnish a quantitative assessment foundation to measure the oder level of natural water in heavily organieally polluted river.更多还原
