摘要:本文以松花江吉林市段主要排污口亖研究对象,选取了 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,运疄模糊数学盠方法对其污染状
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中, 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 排放超标倍数范围亖 至 ;
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 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
三个排污口排放污水中重金属污染较亖严重,应引起重视。

Abstract: The research object of this paper was the pollution of Songhua River city section of Jilin
port. 14 major outfalls were selected, sampling the content of 8 kinds of heavy metal elements Pb,
Cr, Cd, Hg, As, Cu, Zn, Ni pollution results show that Songhua river in Jilin city
section of the main outlet all but one outlet had Pb emissions that exceeded the standard, Pb
emissions exceeded the standard ratio range from to , Cd, Hg, As, Ni and the
second type of pollutant, such as Cu,Zn
