Abstract

The invention discloses a microorganism-based petroleum decontamination agent, which solves the problem that the degradation efficiency of microorganisms to petroleum is not too high and the degradation effect is not ideal. The present invention includes a solid agent and a bacterial agent, the solid agent is composed of the following components by weight: 1-2 parts of 2-(3,4-dihydroxyphenyl)ethylamine, 10-15 parts of polyglycolic acid resin, wood 1 to 2 parts of element, 2 to 4 parts of carbon tetrachloride; the bacterial agent is composed of Bacillus parabrevius, Bacillus and Saccharomyces lipolytica, and the added amount of the bacterial agent is 1×10 6 ~1×10 9 cuf / g. The invention has the advantages of effectively improving the oil degradation efficiency and the like.

Description

technical field [0001] The present invention relates to a decontamination agent, in particular to a microorganism-based petroleum decontamination agent. Background technique [0002] Gasoline and petroleum contaminated soil and groundwater are decontaminated using conventional techniques, such as soil vapor extraction (SVE), using air jet (AS) enhancement. Gasoline and petroleum (such as hydraulic, motor, and fuel oils) are highly degradable in subsurface environments, so if significant decontamination is required, efforts are needed to maintain appropriate conditions, such as the presence of sufficient concentrations in the release area oxygen, which accelerates the aerobic degradation of gasoline and petroleum compounds. [0003] Conventional techniques (eg SVE) provide the required oxygen supply by constantly replenishing the soil with fresh air, or applying a compressor to deliver air pulses into the ground via air jets. Some decontamination experts even use chemicals ...
