Abstract

The invention discloses microbial powder for petroleum degradation. The problems of low petroleum degradation efficiency and non-ideal degradation effects of an existing microorganism are solved. The microbial powder comprises a solid agent and a microbial agent, wherein the solid agent consists of the following components in parts by weight: 1 to 2 parts of 2-(3,4-dihydroxyphenyl)ethylamine, 1 to 2 parts of activated carbon, 5 to 6 parts of dodecyl hydroxypropyl sulphobetaine, 5 to 6 parts of octylphenol polyoxyethylene ether, 2 to 3 parts of carbon tetrachloride and 2 to 3 parts of a TH-904 water-soluble dispersant, wherein the microbial agent consists of brevibacillus brevis, bacillus and saccharomycopsis lipolytica of which the viable bacterium ratio is (1-2):(6-7):(5-6); the particle size of the activated carbon is smaller than 0.05[mu]m. The microbial powder has the advantage that the petroleum degradation efficiency is effectively improved.

Description

technical field [0001] The invention relates to a petroleum degradation agent, in particular to a microbial powder for petroleum degradation. Background technique [0002] Gasoline and oil-contaminated soil and groundwater are decontaminated using conventional techniques, such as soil vapor extraction (SVE), augmented with air jet (AS). Gasoline and petroleum oils (e.g. hydraulic oil, motor oil and fuel oil) are highly degradable in subterranean environments, thus, if a substantial portion of decontamination is to be done, efforts will need to be made to maintain proper conditions such as the presence of sufficient concentrations in the release zone Oxygen can accelerate 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 employ compressors to deliver pulses of air into the subsurface via air jets. Some decontamination experts even us...
