Engineering Demonstration Study on Pump and Treat Process for Remediation of Groundwater Contaminated by Benzene

Abstract

In this paper, a chemical plant by taking benzene contaminated groundwater treatment project as the main research content, the pollution of groundwater extraction after transport to the air blowing off processing equipment on the ground through 11 groundwater extraction wells, groundwater benzene concentration after treatment is lower than 0.5 mg/ L, reached a comprehensive discharge standard of water pollutants in Beijing city "(DB11/307-2013)" in the provisions of the "water pollutant discharge into the public sewage treatment system limits", after discharge. The operation of this restoration project has accumulated experience in the practice of groundwater rehabilitation engineering in China.
