Biological enhancement treatment technology of polymer system water-based drilling solid waste and greening planting soil

The invention provides a biological enhancement treatment technology of polymer system water-based drilling solid waste and greening planting soil. The biological enhancement treatment technology comprises the following steps: preparing a biological agent for biological enhancement treatment of polymer system water-based drilling solid waste; uniformly mixing the biological agent and the polymer system water-based drilling solid waste according to a weight ratio of 0.1-0.5%wt to obtain a first mixture; adding a nutritional agent accounting for 5-20%wt of the weight of the first mixture and conducting uniform mixing to obtain a second mixture; transferring the second mixture to a treatment place, controlling the water content to be 22%-30%, and treating the second mixture for 30-60 days at a temperature of 15-35 DEG C to obtain greening planting soil; wherein the biological agent is alcaligenes faecalis subsp. faecalis GFB14 or a bacterial suspension or a culture solution or a fermentation product thereof.
