摘要
在红河干流不同污染流域,设立5个环境监测断面,同时选定人烟稀少、无工业、自然条件良好的李仙江加禾断面为对照。利用1999～2002年对水质影响大的DO、COD、BOD5、NH 3-N、NO3-N、NO 2-N、Cu、Pb、Cd、T-P、石油类及SS 12项污染物,均在枯、丰、平3个不同水期采样监测,将监测结果做数理统计分析,研究污染物的迁移、转化规律,并得出:出境断面NH 3-N平均含量高达0.18～0.86m gL/,T-P高达0.045～0.315m g/L,SS高达69～3412m gL/,从而提出小流域治理、退耕还林、城市水网改造及控制含磷洗涤剂使用的建议。
In different pollution area of Honghe River mainstream, we set up 5 environmental monitoring sections, and meanwhile select Jiahe section of Lixianjiang River as comparison, which has good natural condition, less population, and no industry. By using the monitoring data of DO, COD, BOD5, NH3-N, NO3-N, NO2-N, Cu, Pb, Cd, T-P, oil and SS in dry, rich and normal seasons of different water periods from 1999 to 2002, totally 12 pollutants with large effect on water quality, through statistic analysis, we study the moving and transform regulations of pollutants. The average content of NHa-N at exit boundary section highly reaches 0.18-0.86 mg/L, T-P reaches 0.045-0.315 mg/L and SS 69-3 412 mg/L. Therefore the suggestions of small drainage area treatment, backing land to forest, city water network rebuilding and controlling the using of washing reagent which contains phosphorus are put forward.
