In-situ remediation of petroleum contaminated groundwater: Application and prospect of permeable reactive barrier

Remediation of petroleum contaminated groundwater has become one of hotspots in environment research in recent years. PRB is a cost-effective and environmental benign technology. Based on the PRB technology abroad and domestically, this paper puts forward reactive media should be screened based on the ingredients, types and properties of the pollutants. Design and construction of PRB should be rely on the hydrogeological conditions of contaminated site. Immobilizing microorganism is an effective way to improve remediation efficiency and prolong using life of adsorption PRB. PRB has broad application prospects in remediation of petroleum contaminated groundwater.
