AI Technical Summary
Existing oil-contaminated soil remediation agents are made from a variety of materials, involve complex processes, and are costly. They may also cause soil microbial safety issues. Traditional methods are ineffective and time-consuming for remediating oil-contaminated soil with an oil content of more than 10%.
Using fresh plant *Pseudolarix amabilis* stalk fermentation liquid and *Arthrobacter* strain as bioremediation agents, *Pseudolarix amabilis* fermentation liquid is produced through anaerobic fermentation for the remediation of petroleum-contaminated soil. This simplifies the process and reduces costs, does not introduce exogenous microorganisms, and utilizes *Pseudolarix amabilis* to enhance soil fertility.
It achieves efficient remediation of petroleum-contaminated soil with an oil content of 10% to 20%, with a petroleum hydrocarbon degradation rate of over 88.7%. The operation is simple, low-cost, and does not affect the safety of soil biological populations, while shortening the remediation cycle.
