摘要
以2006—2008年的南四湖4条入湖河流水质监测数据为基础,以溶解氧、高锰酸盐指数、5日生化需氧量和氨氮作为监测项目,采用综合水质标识指数评价法对南四湖入湖河流进行水质评价。结果表明,除泗河监测断面水质为Ⅲ类水体外,其他都属于Ⅳ、Ⅴ类水体,污染较为严重。本研究可为南四湖主要入湖河流的污染治理提供一定的科学依据。
Based on water quality monitoring data of four inflow rivers of the Nansihu Lake in 2006,2007 and 2008,the water qualities were evaluated employed to the method of comprehensive water quality identification index,with the indices of dissolved oxygen,CODMn,biochemical oxygen demand and ammonia nitrogen.The results show that the rivers have been in the state of serious pollution,in which the monitoring section of Si River was in Grade Ⅲ of water quality standard,and others were in Grade Ⅳ and Ⅴ.The evaluation results have offered interesting scientific basis for environmental controlling to the inflow rivers of the Nansihu Lake.
