城市和工业聚集区对小流域水环境的影响研究

Study on the Impact of Urban and Industrial Gathering Areas on the Water Environment of Small Watersheds

为分析城市污染源和工业污染源对小流域水质的影响,本文选取Q江流域A县城区和工业园区段为研究对象,以氨氮、总磷、高锰酸盐指数监测数据为评价对象,采用《地表水环境质量标准》(GB 3838—2002)对Q江10个断面水质进行评价分析。结果表明,主要水污染物氨氮、总磷、高锰酸盐指数在整个研究河段呈上升趋势,特别是进入工业园区后,水质迅速恶化。针对水质污染特征,笔者分析了城市和工业聚集区对小流域水质的影响,提出了城市规划建设和水污染防治建议。

In order to analyze the impact of urban pollution sources and industrial pollution sources on the water quality of small watersheds,this paper selects the A county urban area and industrial park section of the Q river basin as the research object,and uses the monitoring data of ammonia nitrogen,total phosphorus,and permanganate index as the evaluation objects,and uses the"Surface Water Environmental Quality Standards"(GB 3838—2002)to evaluate and analyze the water quality of 10 sections of the Q River.The results show that the main water pollutants ammonia nitrogen,total phosphorus,permanganate index showed an upward trend throughout the study section,especially after entering the industrial park,the water quality deteriorated rapidly.In response to the characteristics of water pollution,the author analyzes the impact of urban and industrial gathering areas on the water quality of small watersheds,and proposes urban planning and construction and water pollution prevention and control suggestions.
