模拟实验在四川炼油厂环境影响评价中的应用

为了研究拟建炼油厂表层土壤渗透情况及对特征污染物油的吸附和截留情况 ,实施了渗水实验 ,每隔30min测定一次渗水量 ,渗水实验时间为3h。还实施了土柱淋滤实验 ,土柱长度1.2m ,直径30cm ,装填高度1m ,土柱为五层 ,按层测定实验前后土壤中的含油量。实验结果表明 :预计事故排放及短时的含油污水泄漏 ,将不会对地下水环境质量造成大的影响。

Application of Simulation Test During Environment Evaluation in Sichuan Refinery

To study the permeability of topsoil, and adsorption and interception of characteristic effluent oil around proposed refinery, water seeping test has been conducted with measurement of seepage water volume once 30 minutes, and 3 hours of whole test period. Meanwhile, Leach test of earth pillar has also been carried out with 1.2m in the tube-shaped container's length, 30cm in the earth pillar's diameter and 1m in its height. The earth pillar will be divided into five layers and oil adsorption volume of each layer of that will be measured before and after the test. Test result shows that pollutant drainage after accident and leakage of oily sewage during short period should not affect the environmental quality of underground water.
