本文着重叙述了用生物治理系统治理原油污染土壤的方法,与传统的耕作治理方法相比,它具有占地面积少、操作费用低和效率高等明显的优点;同时,也比采用挖取含油土壤并将其运离现场的处理方法经济。从国外油田巳实行的就地生物治理含油土壤所取得的成果表明,这种治理系统能在10～20周的时间内有效地治理遭原油污染的土壤,可使之达到环保部门所规定的标准,其总处理费用仅为44～150美元/m~3。
This article focuses on the treatment of crude oil contaminated soil with a biological treatment system approach, compared with the traditional farming methods, it has less land area, low operating costs and high efficiency obvious advantages; the same time, than the use of oil-dug soil And be transported away from the scene of the economy. The results obtained from in-situ biocontrol of oily soils already practiced in foreign oilfields indicate that such a treatment system can effectively treat soils contaminated with crude oil for 10 to 20 weeks and meet the standards set by environmental authorities , The total handling costs of only 44 to 150 US dollars / m ~ 3.
