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 method for degrading oily soil based on the combination of Pseudomonas, Bacillus and electric field disclosed by the present invention is specifically implemented according to the following steps: Step 1, using Pseudomonas and Bacillus to prepare bacterial agents for oily soil; Step 2 1. Weigh the oily soil to be treated, pre-treat the oily soil to be treated and fill it into the restoration box for oily soil; step 3, add the bacterial agent for oily soil prepared in step 1 to the restoration box in step 2 In the oily soil in the repair box, an electric field is applied to the oily soil in the remediation box, and the degradation of the oily soil is completed under the joint action of the bacteria agent for the oily soil and the electric field. The invention is based on the oily soil degradation method combined with pseudomonas, bacillus and electric field, can treat the oily soil, and effectively reduces the oil content in the oily soil.

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, 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, which...
