Abstract

The invention discloses a microbial remediation microbial agent and a preparation method thereof. The microbial remediation microbial agent comprises the following raw material: acinetobacter calcoaceticus; bacillus subtilis; bacillus licheniformis; pseudomonas aeruginosa; gordonia paraffinivorans; pseudochrobactrum saccharolyticum; microbacterium oxydans; and achromobacter denitrificans. The preparation method comprises the following steps: (1) weighing the strains according to the weight ratio shown in the specification; (2) strain activation; (3) primary seed fermentation; (4) secondary seed fermentation; (5) industrial fermentation; and (6) blending of the components to obtain a finished product of the microbial remediation liquid inoculant. The microbial remediation agent can degradetoxic and harmful long-chain hydrocarbon substances or organic macromolecular petroleum substances in the drilling cuttings into harmless substances such as low molecules, water and carbon dioxide which are acceptable to the environment, and the degradation rate reaches 90% or above.

Description

Technical field: [0001] The invention belongs to the technical field of microbial repair, and in particular relates to a microbial repair bacterial agent and a preparation method thereof. Background technique: [0002] Drilling cuttings produced in the process of oil and gas exploration and development are the wastes discharged from the solid control system with the drilling fluid during the drilling process. It is a multiphase stable colloidal suspension system containing clay, various chemical treatment agents, sewage , dirty oil and drill cuttings are the main pollutants produced in the process of oil and gas exploration and development. They have the characteristics of high pH, ​​high COD, high stability, and poor biodegradability. Direct discharge will cause great harm to the ecological environment. Improper disposal and excessive discharge of drilling cuttings can cause serious pollution of various environmental media such as soil, surface water and groundwater. In or...
