傍河污染场地地下水修复技术筛选
Screening groundwater remediation technology for riverbank pollution sites
摘要
Abstract
Emerging technologies for remediation of groundwater contamination generally have varied applicability,advantages and disadvantages,but contaminated sites at home and abroad have not yet formed any mature selecting system.How to select individual or combined technology for different types of contaminated sites is of vital importance.A ferroalloy abandoned factory in Jilin was studied.Groundwater pollution was investigated,health risk was assessed,pollutants in groundwater were determined.Hydrogeological conditions and characteristics of target pollutants were analyzed.Groundwater pollution remediation techniques PB (pump and bioreactor),AS (air sparging) and PRB (permeable reactive barrier) were assessed,to obtain a reasonable groundwater remediation scheme by importance order of the criteria (IOC).IOC consisted of six criteria:cost,time,effectiveness,public health and efficiency.The carcinogenic risk of benzo(a)pyrene in the groundwater was found to have exceeded the acceptable carcinogenic risk limit of the single pollutant,which was used as the target pollutant.Under condition of efficiency priority,the PB method was found to be the ideal de-contamination technology.Under condition of economic priority,the AS technology was found to be the ideal de-contamination technology.Under comprehensive efficiency priority and economic priority,PB and AS technology were found to be the ideal de-contamination technology for the site.关键词
