浑河流域水体污染季节性变化研究
|
摘要
为提高浑河流域水环境治理的有效性并明确其水体污染季节性变化特征,文章调查分析了该流域2016年3月—2017年2月期间水环境状况,依据改进的综合水质标识指数法和不同水期的水质指标,识别了影响水体污染的主要因子,分析了其时空变化特征。结果显示:浑河流域年内pH值变化区间为6.40～8.08,电导率在枯水期最高;沿岸生活污水和工业废水点源污染为影响浑河流域水环境质量的主要因素,各监测断面的综合水质在平水期和枯水期均未达到水质要求;流域综合水质指数自上游至下游逐渐增大,主要为NH_3-N和COD污染。
Water environment situation of the river basin from March 2016 to February 2017 is investigated and analyzed in the paper, in order to improve the effectiveness of Hunhe River basin water environment treatment and make clear its seasonal variation characteristics of water pollution. The main factors affecting the water pollution is recognized, and the temporal and spatial variation characteristics are analyzed according to the improved comprehensive water quality identification index method and different periods water quality index. The results show that the pH value of Hunhe river basin varies from 6.40 to 8.08, and the conductivity is the highest in the dry season. Point source pollution of coastal domestic sewage and industrial wastewater is the main factor affecting the water quality of Hunhe river basin. The comprehensive water quality of all monitored cross section does not reach the water quality requirements during normal season and the dry season. The river basin comprehensive water quality index is gradually increased from upstream area to downstream area, namely NH_3-N and COD pollution.
