摘要

嘉陵江一级支流西充河为四川省严重污染河流。经监测分析

2009年西充河水质被评为劣5类

主要污染物包括氨氮、化学需氧量、总氮、总磷、粪大肠菌群等。以西充河南充市段为研究对象

运用盲数理论测算

对比了西充河雷打石和拉拉渡2个断面2003—2009年的水质监测资料。2个断面的水环境容量值CODCr为637.01kg/d

—N为0.76kg/d。2断面间的化学需氧量、氨氮超过水环境容量值(W

COD

=874.59kg/d

—N

=116.34kg/d)分别是允许水环境容量的1.37和153倍。为了达到国家3级水质标准

西充河的治理已经刻不容缓。

Abstract

Xichong River in Sichuan Province

a tributary of Jialing River

has been polluted seriously.In 2009

water quality of Xichong River was assessed to be the bad fifth grade through monitoring and analysis.The main contaminants in the river are ammonia nitrogen

chemical oxygen demand

total nitrogen

total phosphorus

and fecal coliform.By taking the Nanchong segment of Xichong River as the research object

the data from water quality monitoring at Leidashi and Laladu observation sites from 2003 to 2009 are analyzed based on blind number theory.As for the water environment capacity at the two sites

CODCr is found to be 637.01 kg/d and NH3—N

0.76 kg/d.Chemical oxygen demand(WCODCr) and ammonia nitrogen(WNH3—N) exceeding the standards at the two sites are 874.59 and 116.34 kg/d

being 1.37 times and 153 times of the allowed value

respectively.In order to reach the third grade of national water quality standards

it is urgent to control the pollution of Xichong River.
