Abstract

The invention relates to a recovery technology for contaminated soil, which concretely is a recovery method and appliance for contaminated soil. The method puts in fertilizer according to the weight of the contaminated soil, in the material, C:N:P=80-120:9-11:1-2, 1-5% solid bacteria agent and 14-25% water, the pH value is adjusted to 6-8, they are put into the pile corroding pool after being blended. The device is canopy type structure, in which there has a pile corroding pool, on which there is the contaminated soil piles, there has a penetration resisting layer under the pool, there has a water pipe for assembling nozzle above the pool, in the pool there also has ventilation pipe distributed with ventilation apertures, which are connected to the fan; there lays with plastic cloth on the canopy. The invention is easy to be controlled, and it has no contamination.

Description

technical field

[0001] The invention relates to a polluted soil remediation technology, in particular to a polluted soil bioremediation method and facility. Background technique

[0002] Bioremediation of organic matter-contaminated soil includes petroleum-contaminated soil. At present, there are two main types: in-situ treatment and ex-situ treatment. The in-situ biological treatment method is to directly adopt bioremediation technology in the polluted area. This technology is suitable for large areas of lightly polluted soil. The cost is low, but the processing cycle is long because the environmental conditions are not easy to control. Ex-situ bioremediation technology is to transport contaminated soil to a specific engineering site for bioremediation. This method can ensure ideal conditions for biodegradation, so it has a good treatment effect on contaminated soil and can prevent the transfer of pollutants. It is regarded as a A processing technology with broad applicati...
