摘要
图们江地区５条河流１８个断面水环境质量研究表明，本区地表水污染比较严重，大部分河流断面水质在Ⅳ、Ⅴ级水平，只有珲春河水质优于Ⅲ级。除布尔哈通河水质继续呈下降趋势外，其它河流污染水平基本得到了控制。河流污染物比较固定，主要是ＳＳ、ＣＯＤ、ＢＯＤ、ＡＲ－ＯＨ、Ｎ－ＮＨａ。主要污染行业是化纤业、造纸业和矿业。在区域开发的激励模式下，工业总产值增长率＞２５％时，其污染物负荷将超出水环境的承受能力，在制定本区开发战略时必须制定相应的环境保护对策。使经济、社会、环境得到协调发展。
After the survey of pollution source, a study on surface water quality assessment and forcast is given by means of grey system method, fuzzy mathematic method and multivariated analysis method. Based on it, aquatic cnviromment qulity feature, treatment measures and enviromental sterategy are proposed. Quality of aquatic environment on 18 sections of 5 rivers in Tumen River area was studied. The results showed that the pollution of surface water was serious. Water quality of most rivers is between III and IV standard except Hunchun River deteriorated gradually, pollution level of other rivers has been controlled. Main pollutants (including SS, COD, BOD, AR-OH, N-NH 3) resulted from discharge of chemical fiber industry, pulp and paper industry and mines. If the growth rate of industrial value is higher than 25 percent under the encouraging model of regional exploitation, the pollution load will overtake the bearing force of aquatic environment. Thus, some of protection program against pollution must be worked out in order to achieve harmonious development of economy, society and environment.
