摘要
依据污染分担率大小,划分地表水污染类型,并冠以主名称、副名称。通过实例调查,确定污染分担率界线,提出以15%≤K<40%的指标作为副名称,以40%≤K<70%的指标作为主名称。定名时,副名称在前,主名称在后,组成"兼有‘××’污染的‘××’污染型的"的形式。能比较直观地反映地表水的主要污染特征。应用起来简单易行,可操作性强,容易为大众理解和接受,避免了数字评价的枯燥无味,有一定的现实意义。
This paper discusses the method for classifying surface water pollution and giving it a main title as well as a subtitle according to pollution share rate. The limits of pollution share rate are determined on the basis of example investigation and it is suggested to use the quota of 15% ≤ K ≤40% as the subtitle and that of 40%≤ K ≤ 70% as the main title, which can give an im- mediate indication of the main features of surface water pollution. Being simple to implement and easy to understand, this method has practical significance.
