    Abstract: 一种快速处置含油土壤的方法及应用。该法将污染场地含油土壤挖出，转移至堆场中；堆场内铺设防渗层（3），底部铺设导流材料（5），其上部铺设沼渣、菌剂、碳源、营养添加剂及含油土壤的混合层（4），混合层（4）上部放置内电解陶粒；运行过程中，不定期从堆场上部注碳源溶液，随后将渗滤液通过底部导流材料（5）收集至渗滤液收集系统中，随后不定期将渗滤液回流至堆场上部进行回灌。经过该方法处理含油土壤，仅需10-60天时间即可将污染土壤修复至民用建设用地标准。

    Abstract: During in situ electroremediation of soil electric fields generated by electrodes (10, 12) that are located in the soil are used to move contamination, complexing agents, chemical reagents and/or nutrients through soil or to heat the soil. Control of the voltages and/or currents on or through the electrodes (10, 12) is used to prevent electrode clogging problems, to reduce unnecessary power consumption and/or to prevent boiling. In one aspect (electrokinetic remediation and electro heating) the current through selected electrodes (10, 12) is temporarily stepped down if the onset of clogging and or boiling is detected from an increase in the electrical resistances from an electrode into the soil. Preferably an effect of soil resistivity changes on the detection is removed by using sensing electrodes (14a, 14b) in the soil. In another aspect (elektrokinetic (bio) fence / screen) the voltage or current is adapted dependent on measured groundwater flow speed changes, so that the method remains effective with minimum power consumption. In yet another aspect (electrokinetic phyto remediation) polarity reversals of the current are timed using cumulative current measurements.

    Abstract: The present invention relates to a method that comprises introducing into a zone to be cleaned a solution of micro-organisms capable of oxidising crude oil. Electrodes and more precisely an anode and a cathode are introduced into the cleaning zone, while an electrical direct current is generated between them in order to create an electro-osmotic movement of the solution containing the crude-oil oxidising micro-organisms. The solution which accumulates at the cathode is then collected and further re-introduced into the cleaning zone. According to the present invention, the crude-oil oxidising micro-organisms may be introduced to a desired depth, while the conditions of their vital functions may be improved relative to the oxygen content and to humidity. This invention may also be used to reduce the losses of solution containing the crude-oil oxidising micro-organisms by maintaining said solution within the cleaning zone.
