Problems solved by technology

[0006] However, judging from the current status of comprehensive utilization technology, there is still a lack of advanced treatment and utilization technology with high added value. All parts of the country should adapt to local conditions and seek reasonable and effective treatment methods for comprehensive utilization and solving the problem of oil sludge pollution. If a kind of The economical and practical method of harmless treatment of oily sludge and recovery of residual oil will not only produce certain economic benefits, but also reduce pollution, and ultimately make a huge contribution to environmental protection and human health

Abstract

The invention discloses an oil polluted soil degrading method based on the combination of zoogloearesiniphila, bacillus and an electric field. Specifically, the method comprises the following steps: 1, preparing a bactericide for oil polluted soil treatment with zoogloearesiniphila category and bacillus category; 2, weighing to-be-treated oil polluted soil, carrying out pretreatment on the to-be-treated oil polluted soil and filling an oil polluted soil restoration box with the pretreated oil polluted soil; and 3, adding the prepared oil polluted soil bactericide in step 1 into the oil polluted soil in the restoration box in step 2 and applying the electric field on the oil polluted soil in the restoration box, so as to complete the degradation of the oil polluted soil under the cooperative action of the oil polluted soil fungicide and the electric field. According to the oil polluted soil degrading method based on the combination of zoogloearesiniphila, bacillus and the electric field, the oil polluted soil can be treated and the oil content of the oil polluted soil can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of treatment methods for oily soil, and in particular relates to a method for degrading oily soil based on the combination of kinetobacteria, bacillus and electric field. Background technique [0002] At present, the most difficult thing to deal with in solid waste treatment is oily sludge, which is produced in the accidental leakage of crude oil and equipment management such as drilling, operation, workover, oil production, gathering and transportation, storage and transportation in the process of crude oil exploitation. Yes, its existence has caused great hidden dangers to the surrounding ecological environment, and it must be treated harmlessly. If the oil in the oily sludge directly enters the soil, it will cause great pollution to the soil. [0003] Normally, the pollution of oil to the soil is mainly concentrated in the surface layer of about 20cm. It has strong adhesion and low emulsification ability...
