关于城市典型区域地下水环境质量现状研究

The Study on Present Situation of Groundwater Environmental Quality in Typical Urban Areas

本研究以锦州市饮用水源地、铁合金厂、石化公司、垃圾处理厂和电厂的周边区域水质为研究对象,共采集25份具有代表性的水质样品,分别进行25项挥发性有机物的含量分析,监测数据用于研究典型区域水质的污染状况。采用Rapantetal.环境风险指数法的评价结果表明,石化公司周边地区产生风险的污染物主要为六氯丁二烯,中等环境风险级别的样品占75%;铁合金厂周边地区产生风险的污染物主要为四氯化碳,中等环境风险级别的样品占12%,其他典型区域水质状况良好。由此,针对锦州市典型区域水质的污染状况,提出相应的污染防治对策。

In this study, the water quality in the surrounding areas of jinzhou drinking-water source, ferroalloy plant, petrochemical company, waste treatment plant and power plant were taken as the research object. A total of 25 representative water quality samples were collected for analysis of 25 volatile organic compounds, and the monitoring data were used to study the pollution status of water quality in typical area. The evaluation results by Rapant et al. Environmental risk index method show that the main pollutant at risk in the surrounding area of petrochemical companies is hexachlorobutadiene, and the samples with medium environmental risk level account for 75 %;Carbon tetrachloride is the main pollutant producing risk in the area around the ferroalloy plant.Samples of medium environmental risk level account for 12 %. Water quality in other typical area are in good condition. Therefore, according to the pollution situation of typical regional water quality in jinzhou city, the corresponding pollution prevention measures are proposed.
