地质屏障的防护性能在采油废水污泥填埋中的作用机理研究

Function Mechanisation Research of Protective Performance of Geology Defence In Extraction Waste Water and Sludge Filling and Burying

地质屏障对有害物质的防护性能取决于地质屏障的岩石性质、水文地质特征以及污染物本身的物理化学性质。为了了解污泥填埋场表层土壤性质、土壤渗透性能及对特征污染物的吸附和截留情况 ,实验工程以克拉玛依白碱滩六九区及 81# 污水处理站废水及所产生的污泥为实例 ,以六九区污水处理站污水贮存塘区为试验场地 ,实施现场渗水试验 ,并对该试验场地不同剖面、不同层位的土壤吸附参数进行测定 ,以评价地质屏障的防护作用 ,在满足环境保护的前提条件下 ,尽量减少工程投入 ,使污泥填埋工程及投资在社会、环境及经济三方面更趋合理、可行。

The protective performance of geology defence against harmful matter is decided by rock property of geology defence,charact of hydrogeology and physical chemistry property of pollutant itself.In order to know surficial soil property of sludge burying ground,soil permeability and adsorption and retention status of characteristic pollutant,experiment project taking waste water and its produced sludge of Liujiu Area of Baijiantan Kelamayi and No.81 Sewage Treatment Station as example,Sewage Storage Pond area of Liujiu Area Sewage Treatment Station as experimental ground,carrying out infiltration test in site,and soil adsorption parameter of different section and position in the experimental ground measuration,as appraising protective action of geology defence,under the presupposition condition of meeting the needs of environmental protection,decrease investment in engineering as less as possible and makes sludge burying engineering and investment in three respects of socity,environment and economy be more reasonable and feasible.
