摘要
本研究调查了松花江从松花湖至九站段沿岸排污情况,根据调查的93个排污口分布情况及江段特点,在该江段设置了14个监测断面,同时对各监测断面氨氮、总磷、CODMn、BOD5及溶解氧等水质因子进行枯水期、平水期、丰水期的水质监测,运用模糊评价法对监测结果进行评价。结果表明:松花江吉林市段存在一定程度的有机污染,局部断面未达到功能区标准。
The research team investigated the drain contamination on the coast of Songhua River from Songhua Lake to Jiuzhan Station.Then 14 monitoring sections were set according to the distribution of the 93 drainage outlets and the characteristics of the Songhua River in Jilin City.Meanwhile,each section had been monitored in the Dry season,Wet season and General water season on the water quality factor of NH3-N,TP,CODMn,BOD5 and DO,etc.Afterwards fuzzy evaluation method was applied to evaluate the monitoring results.The evaluation results indicated that there exist certain degrees of organic pollution as well as some monitoring sections of which the water quality was not up to the standard of the function area.
