浊漳河流域主要污染物与污染评价

The Main Pollutants and Polluted Evaluation in Zhuozhang River Basin.

通过对浊漳河流域2004年21个监测断面的枯水期(5月)、丰水期(8月)和平水期(10月)地表水体采样分析, 确定其中主要污染物依次为NH3-N、COD、BOD5、CODMn和挥发酚。整个流域河段污染程度依次为浊漳南源>浊漳干流>浊漳西源>浊漳北源。污染源主要来自于河段上游点源污染。

Through the analysis about water samples from 21 monitoring sections in low-period （May）, high-flow period （August） and mean- flow period （October） in Zhuozhang river basin in 2004, the main pollutants are NH3-N, COD, BOD5, CODMn and volatile hydrozybenzene. The polluted degree in Zhuozhang river basin is： the south source 〉 the master stream 〉 the west source 〉 the north source. The pollutants are mainly from point pollution source of upper stream of Zhuozhang river.
