Abstract: Polycyclic Aromatic Hydrocarbons are common persistent organ ic pollutants in water. Their migration and transformation pathway included chemisorption, volatilization, photolysis, chemical degradation and so on. Among them, the main removal means of PAHs in water are biocondensation and degradation. This paper combined the domestic and foreign research dynamics, introduced the enrichment and degradation characteristics, mechanism and influence factors, and then focused on the PAHs degradation mechanism and the effects of environmental factors to PAHs degradation efficiency. Meanwhile this text looked to the future research directions and pointed out some research direction need to be strengthened, such as the organic pollutant adsorption model and gene regulation mechanism in pollutant degradation process.
