Research Progress on Bioremediation of Organic Contaminated Soil in Coal Chemical Site

With the continuous development of coal chemical industry, the problem of soil organic pollution is becoming increasingly serious, resulting in serious environmental pollution. In order to promote the application of bioremediation technology in the remediation of organically contaminated soil in chemical sites, the distribution of coal chemical enterprises and the characteristics of site soil organic pollution in China were investigated. The soil bioremediation technology in organically contaminated sites was introduced in terms of biostimulation and bioaugmentation. Some existing problems of soil bioremediation technology in organically contaminated sites were analyzed, and possible solutions to the existing problems were put forward accordingly.
