由于江西地区工农业的迅速发展和人民生活水平的提高,水质恶化现象严重,污染态势急需遏制.对江西地区典型村镇河流蒋巷河周边进行调研,选取蒋巷河两个断面,现场采样,监测其2011年8月至2012年7月河水水质.结果显示:总氮(TN)、氨氮(NH3-N)、总磷(TP)和有机物(CODCr)浓度分别为1.176~39.55,0.325~18.925,0.085~6.040,17.472~106.84 mg·L-1,河水长期处于劣Ⅴ类富营养化状态,并分析其水质变化趋势及原因.

Because of the rapid industrial and agricultural development and the improvement of people's living standard in Jiangxi,the deterioration of water has become serious,which calls for urgent pollution regulation. In order to probe into the village river pollution situation in Jiangxi,this paper selects a typical river,Jiangxiang River near Jiangxiang Village in Nanchang,as a case study. Firstly,two sections of Jiangxiang River are deter-mined and the relevant field sampling is conducted,then the water quality from August 2011 to July 2012 is monitored. The results show that the concentrations of TN,NH3-N,TP,CODcr are 1.176-39.55,0.325-18.925, 0.085-6.040,17.472-106.84 mg·L-1,and the water in the river has been in the V-eutrophication status for a long time. Finally the paper analyses the reasons for the variation trend of the water quality and explores the compre-hensive treatments of the sewage.
