固体废物处理场对地下水体污染评价方法研究

Study on Evaluation Method of Groundwater Body Pollution in Solid Waste Treatment Site

为了提高固体废物处理场对地下水污染评价的精确度,提出一种基于迭代指数法的,固体废物处理场地下水体污染评价方法。首先分析了地下水体污染指标分级方法,然后建立了地下水污染风险评价模型,最后以某城市的固体废物处理场进行了验证。结果表明,固体废物处理场地下水体污染风险主要取决于自身防护系统功能是否完善、处理场所在地的地质条件和气候条件等主、客观因素,为固体废物处理场的建设提供了依据。

In order to improve the accuracy of groundwater pollution assessment in solid waste disposal sites, a method based on iterative index method for groundwater pollution assessment in solid waste disposal sites was proposed.Firstly, the method of grading groundwater pollution indicators was analyzed. Then a groundwater pollution risk assessment model was established. Finally, the solid waste disposal site in a certain city was verified. The results show that the risk of groundwater contamination in solid waste disposal sites mainly depends on the main and objective factors such as the perfection of the function of the self-protection system, the geological conditions and the climatic conditions of the site where the site is located, and provides a basis for the construction of solid waste disposal sites.
