Method for repairing soil at high-efficient power of bacterial to emulsify petroleum

Abstract

A method for repairing soil at high speed and increasing the power of bacteria to emulsify petroleum includes such steps as preparing BH culture medium from MgSO4.7H2O, K2HPO4, KH4PO4, FeCl3 or FeSO4, NH4NO3, CalCl2, citric acid and water, culturing Acinetobacter calcoaceticus for 5 days while rotating at 180 rpm, adding diesel oil and fermented liquid, laying aside, cyclone oscillation, and laying aside.

Description

technical field

[0001] The invention relates to an environmental protection technology, in particular to a method for cultivating bacteria. In the prior art, there is a method for repairing oil-contaminated soil by using high-efficiency bacteria strains; the present invention is a method for specifically cultivating the high-efficiency bacteria used in the method to improve its ability to emulsify petroleum. Background technique

[0002] Petroleum is a complex of hundreds of chemical compounds. They are generally divided into four categories according to their properties: saturated hydrocarbons (including normal paraffins, branched alkanes and cycloalkanes), aromatic hydrocarbons (including monocyclic, bicyclic and polycyclic aromatic hydrocarbons, and cycloalkanes with alkyl side chains and fusions) ), resins (compounds composed of pyrimidine, quinoline, carbazole, thiophene, sulfoxide, amino compounds), and asphaltenes (complexes of naphthenic acid, sulfide, polyphenols, ...
