Abstract

The invention discloses a solid microbial inoculum that is used for decomposing petroleum pollutants and petroleum products, and a preparation method and applications of the solid microbial inoculum; and the invention belongs to the technical field of biological reparation in the emergency processing of accidents including petroleum pollution of soils and petroleum product leakage. The solid microbial inoculum is prepared by mixing a pseudomonas aeruginosa bacteria fermented fluid, turfy soil and bran with proportion by weight: 0.1-1:1:0.2-0.5, and the effective living bacteria number of pseudomonas aeruginosa bacteria inside the pseudomonas aeruginosa bacteria fermented fluid is 10 to 10 in each milliliter. The solid microbial inoculum has the advantages of high liveness in soil and quick growth, does not cause secondary environmental pollution, and can be used in the biological reparation on the spot of accidents including petroleum pollution of soils and petroleum product leakage.

Description

technical field

[0001] The invention relates to a solid microbial bacterial agent for degradation of petroleum pollutants, a preparation method and application, and belongs to the technical field of bioremediation for emergency treatment of petroleum-contaminated soil and petroleum product leakage accidents. Background technique

[0002] Bioremediation, also known as biological remediation, biological restoration, ecological restoration or ecological restoration, refers to the process of using the organisms in the treatment system, mainly the metabolic activities of microorganisms, to reduce the concentration of pollutants on the polluted site or make them harmless. Since bioremediation degrades pollutants by dosing or stimulating organisms in the soil, it does not destroy the soil environment required for plant growth. The final product is CO 2 、H 2 O and other substances, so it is environmentally friendly and does not produce secondary pollution. In addition, compared w...
