Abstract: This paper took an industrial site remediation project in Shanghai as a case study. Comparing the single well pumping, multiple wells at the same time pumping and multiple wells cyclic pumping, etc., the effect on the pumping effect was studied according to the field water treatment pilot selection of the best pharmaceutical dosage ratio of the wastewater treatment, which could be used as a basis for the design of the groundwater pumping project. In the meantime, the polluted groundwater pumping remediation construction process case study was analysed after pumping remediation treatment A & B area of contaminated groundwater arsenic concentration in 45 days to reach the target value of the remediation, C area of contaminated groundwater pollutants in 70 days to reach the target value of the remediation.The effect of the assessment confirmed that the remediation of the standard. Finally, the problems of practical application of extraction remediation and the direction of subsequent technological development are discussed and suggested. This paper could provide a reference for the application of other extraction remediation technologies in groundwater contamination remediation.
