中文摘要:
      东江源区已成为国家生态补偿试点及珠江流域水资源保护规划典型试点区域。本文综合运用单因子指数评价法、均值型污染指数法、季节性肯达尔检验法及等标污染负荷法,基于东江水定南水下历河2003~2014年水质监测资料和2013年排污调查资料,从水功能区水质现状、水质演变趋势、主要污染物等方面分析了该河段水质特征变化。结果表明该河段饮用水源区水质清洁,保留区重污染,工业用水区严重污染。稀土冶炼、农业开发、污水处理厂废水排污是该河段主要污染成因,并由此提出相应的治理措施。
英文摘要:
      Dongjiang River source zone has become the national ecological compenastion pilot zone and the typical pilot zone of water resources protection plan in the Pearl River Basin.The water quality characteristies change is analyzed from the current situation of water quality,water quality evolution trend and main pollutants in the water function zone by the integrated use of single factor index method,average pollution index method,seasonal Kendall test method and the equal standard pollution load method,based on the 2003~2014 water quality monitoring data and the 2013 sewage drainage survey data of Xiali River of Dingnan River of Dongjiang River.The results show that the water quality of drinking water source zone is clean,reserved zone is heavy pollution,industrial water utilization zone is serious pollution.It was demonstrated that the ammonia nitrogen,chemical oxygen demand,PH value,arsenic and total phosphorus etc. are the main contaminants of the river.Rare earth smelting,agricultural development,waste water drainage of sewage treatment plant are their main reason of the river pollution.Finally,the corresponding measures for ecological regulation is proposed.
