Remediation technology of low oil content soil
In combination with Tianjin Institute of industrial biotechnology, Chinese Academy of Sciences, the company adopted microbial remediation technology for low oil-bearing soil. According to the parameters of organic matter, total nitrogen, total phosphorus, loose degree and so on, the technology uses aerobic composting to add nutrients and inoculate composite degradation bacteria. Through the cooperation of dominant bacteria, the residual oil sludge was deeply degraded, and the oil content after degradation could reach below 0.4%, which is in line with the standard of agricultural land. Its main advantages: low cost of treatment, no damage to the micro ecological environment; small requirements for equipment and supply engineering, small quantities of engineering; suitable for large-scale soil pollution.
