摘要
为研究经济发展对当地水体环境质量的影响,本文对上栗县栗水河水体环境质量进行了为期五年的长期监测.单因子分析结果表明,栗水河佛岭断面水质以Ⅱ类为主,邓家洲断面水质以Ⅲ类为主,各断面水质基本达到水环境功能区划的要求.综合污染指数法表明,2011-2015年,佛岭断面各年份综合污染指数均低于邓家洲断面,但两断面综合污染指数总体均呈现上升趋势.通过对各污染指标的污染指数(Pi j)和污染分担率(Ki)进行排名可知,佛岭断面和邓家洲断面的主要污染指标均为总氮、化学需氧量(COD)、高锰酸盐指数和五日生化需氧量(BOD5)等有机污染因子.通过对栗水河水质进行监测评价,分析影响水质的原因,提出污染防治对策,可为栗水河的治理提供有效依据.
In order to investigate the effect of economic development on the water quality of local river,in this paper,the water quality of Lishui River was monitored for five years. The single factor evaluation method showed that the water quality of Foling monitoring section was mainlyⅡ,the water quality of Dengjiazhou was mainly Ⅲ,both sections of Lishui River could meet the requirements of water function zoning. The comprehensive pollution index method showed that the indexes of Foling monitoring section were lower than those of Dengjiazhou monitoring section in each year from 2011 to 2015,but the comprehensive pollution index of both sections showed an upward trend. The ranking of pollution index(Pi j） and pollution share rate(Ki） of each pollutant showed that the main pollutant targets of both sections were mainly organic pollutants,such as total nitrogen,chemical oxygen demand(COD）,permanganate index and five days＇ biochemical oxygen(BOD5）. According to the result of water quality monitoring and evaluation of Lishui River,the pollution controlling measures were proposed,which could provide effective basis for river management of Lishui River.
