摘要
通过对浊漳河流域1996～2000年21个监测断面的枯水期 (5月 )、丰水期 (8月 )和平水期 (10月 )地表水采样分析 ,研究了其中主要污染物CODcr、BOD5、NO3-N、NO2-N和挥发酚的季节动态变化特征。结果表明 :污染物浓度随季节变化特征较为复杂 ,但总体表现了枯水期>平水期>丰水期的总体特征 。
The season change characteristics of main pollutants(COD cr ,BOD 5 ,NO 3 -N,NO 2 -N and volatile hydroxybenzene)in the surface water of Zhuozhang river basin,were studied by water sample analysis of21monitoring sections in low_flowperiod(May),high_flowperiod(August)and mean_flowperiod(October)from1996to2000.The results showed that seasonal change of pollutant concentration was relatively complex.But in all,these change charˉacteristics were low_flow period>mean_flow period>high_flow period and were related mainly to the difference source pollutants of difference sections.
