摘 要:2005年夏季对海河流域9条主要河流的营养盐及入海有机污染物调查显示,首要污染物是石油类的有3条河流,1条为CODMn,其余5条河流的首要污染物均为营养盐。采用综合营养状态指数法评价,徒骇河处于中营养状态;滦河、马颊河、大清河处于富营养状态,海河、蓟运河、潮白新河、独流减河、子牙新河5条河流处于重度富营养状态。有机污染物的调查显示,海河流域9条河流采样点的TOC的平均值为20.57 mg/L,CODMn的平均值为6.70 mg/L。海河流域河流2005年夏季主要污染物入海总量为52 174 t,其中CODMn和NH+4-N的入海量起主导作用,约占总量的77.1%。Through an investigation of the nutrients and organic pollutants entering the sea via nine rivers in the Haihe river basin in the summer of 2005,we found that there were three rivers in which the key pollutants were petroleum,in one river the key pollutant was CODMn and the remaining fiver rivers whose were rich in nutrients.The rivers were evaluated by the comprehensive trophic state index with the following results: the Tuhaihe river was meso-eutrophic,the Luanhe、Majiahe and Daqinghe rivers were eutrophic,particularly the Haihe、Jiyunhe、Chaobaixinhe、Duliujianhe and Ziyaxinhe rivers were extremely-eutrophic.According to a survey of organic pollutants,the average TOC value for the nine rivers was 20.57 mg/L,and the average CODMn was 6.70 mg/L.The pollutant fluxes entering the sea via the rivers in the Haihe river basin were 52174 t in the summer of 2005,of which CODMn and NH4+-N,which approximately accounted for 77.1% of the total played a leading role.
