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 oily soil degradation method based on combination of pseudomonas, zoogloea and an electric field. The oily soil degradation method specifically includes step 1, preparing an oily soil bactericide from the pseudomonas and the zoogloea; step 2, weighing and pretreating to-be-treated oily soil, filling a oily soil remediation box with the pretreated oily soil; step 3, adding the oily soil bactericide obtained in the step 1 to the oily soil in the remediation box in the step 2, applying the electric field to the oily soil in the remediation box, and completing degradation of the oily soil under the joint action of the oily soil bactericide and the electric field. The oily soil degradation method based on combination of the pseudomonas, the zoogloea and the electric field has the advantages that the oily soil can be treated and oil content of the oily soil can be reduced effectively.

Description

technical field [0001] The invention belongs to the technical field of oily soil treatment methods, and in particular relates to a method for degrading oily soil based on the combination of Pseudomonas, Kineticum and an 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, w...
