摘 要: 以松花江吉林市段主要排污口为研究对象,选取14个主要排污口,采样测定Pb,Cr,Cd,Hg,As,Cu,Zn,Ni 8种重金属元素含量,运用模糊数学方法对其污染状况进行评价分析。结果表明:松花江吉林市段主要排污口废水第一类污染物中,Pb属于超标排放,14个排污口中有13个Pb排放超标,Pb排放超标倍数范围为1.325~3.163;其他第一类重金属Cr,Cd,Hg,As,Ni及第二类Cu,Zn均达到安全排放;8种重金属不会对松花江水体产生较大污染。松花江吉林市段下游江北工业区排污口3号、4号中Hg的排放含量比其他排污口Hg排放含量高很多,5号As和Cd的含量比其他排污口高很多。上述3个排污口排放污水中重金属污染较为严重,应引起重视。
关 键 词: 环境质量监测与评价;松花江;吉林市;排污口;重金属污染;模糊评价法

Abstract: In this paper, 14 major outlets in Jilin city section of Songhua river were selected as the main subjects to survey and evaluate heavy metal pollution by sampling the contents of eight kinds of heavy metal pollutants including Pb, Cr, Cd, Hg, As, Ni as the first type pollutant and Cu, Zn as the second type pollutant. Fuzzy evaluation method was used for appraising heavy metal pollution. The results showed that thirteen out of fourteen outlets in Jilin city section of Songhua river had Pb emission content exceeded the pollutant emission standard over 1.325 to 3.163 times while Cr, Cd, Hg, As, Ni, Cu and Zn emission contents had all met their pollutant emission standards. Thus, these eight kinds of heavy metal emissions had minor influence on polluting the water body of Songhua river. As for emissions in the downstream of Songhua river Jilin city section, the content of Hg from outlets No. 3 and No. 4 located in Jiangbei industrial zone was much higher than that of the rest sampling outlets. Meanwhile, the contents of As and Cd from No. 5 sampling site were much higher than that of the other outlets. Heavy metals pollution of the mentioned 3 outlets was more serious and should be brought to attention.
