招远市界河流域水土污染特征及修复技术研究

随着招远市社会经济的发展,人类对环境质量的要求越来越高,人类工程活动对土壤造成的污染问题也逐渐显露,加强土壤环境管理是我国环境保护的一项基础性工作,具有十分重要的意义。为查明界河流域地下水及土壤现状,在界河流域自上游到下游布设监测点位,共取水质分析样品66组和土壤样品19组进行化验,分析了地下水和土壤污染监测数据,总结了招远界河流域的水土污染特征,认为界河上游和中游流域土壤以有机污染为主,下游土壤污染为重金属污染,部分区域叠加有机污染形成复合污染,主要重金属成分为镉、砷、汞。结合环境工程领域的环境修复技术,提出了适宜的水土修复方案,为招远市环境修复提出可行性建议。

Study on Soil and Groundwater Pollution Characteristics and Remediation Techniques of Jiehe Basin in Zhaoyuan City

Accompanying with the development of social economy in Zhaoyuan city, people''s requirements on environmental quality are getting higher and higher, and the pollution caused by human engineering activities is gradually revealed. However, the soil environmental problems and pollution prevention work have not been received due attention for quite a long time in China. Strengthening soil environmental management is a basic work of environmental protection in China, which has very important significance. In order to find out present situation of groundwater and soil in the Jiehe river basin, monitoring sites have been set up from upstream to downstream. 66 groups of water quality analysis samples and 19 groups of soil samples have been collected for laboratory analysis. By analyzing the monitoring data of groundwater and soil pollution, the characteristics of water and soil pollution in Jiehe river basin have been summarized in this paper. The soil in the upper and middle reaches of the river is mainly polluted by organic pollutants. The soil in the lower reaches is polluted by heavy metals, while some area is polluted by heavy metals and organic pollutants, and the main heavy metals are cadmium, arsenic and mercury. Combining with environmental remediation technology in the field of environmental engineering, suitable remediation plans and feasible suggestions of soil and groundwater in Zhaoyuan city have been put forward.
