Review on SVE System Exhaust Treatment Technology for VOCs Polluted Sites Remediation

Nowadays，people pay more and more attention to soil vapour extraction technology（SVE）.The main component of SVE exhaust is volatile organic compounds（VOCs）and related purification technology research is needed in China.Conventional VOCs control technologies mainly include incineration，condensation，adsorption and absorption technologies.It has been found that biofilter was a promising method to purify SVE exhaust with good performance，effectively VOCs purification effect and save secondary pollution.It is more suitable to purify SVE system exhaust compared with other methods.
