Research progress of pollution status and degradation technology of PAHs in road stormwater runoff
The pollution level of some roads in China is little different from that of foreign countries,but the difference between South and East China and North and central China is obvious,which is related to the level of urban development,population and climate,among which Shanghai,Shenzhen,Tianjin and other cities are the most polluted.At present,the research hotspots of PAHS pollution degradation in water can be divided into biological and non-biological technologies.Most of the latest researches focus on mi-crobial degradation of PAHs,which mainly focus on screening microbial strains and microbial stimulation.The effect and applicability of microbial remediation are far superior to phytoremediation and physico-chemical remediation.However,the future research focus is more inclined to microbial combined plants,microbial combined microorganisms,microbial combined physical materials and other directions.By col-lecting related research data of PAHS pollution on roads at home and abroad,the load,sources,character-istics and distribution of PAHS pollution on roads were reviewed,and the applicability of current PAHS treatment technology in water and rainwater runoff treatment facilities was summarized,aiming at providing reference for future PAHS pollution control on roads in China.
