两种PRB反应介质去除地下水中硝酸盐效果对比
The Contrast about Removal Effects on Nitrate in Groundwater for Two Reaction Medium of PRB
摘要
Abstract
[ Objective] The aim was to research the removal effects on nitrate in groundwater for different reaction medium of PRB. [ Method] According to the simulated groundwater and with the nitrate contamination of groundwater as material, the removal effects on nitrate in groundwater for immobilized microorganisms and zero-valent iron and activated carbon reaction mediums of PRB were reviewed. [ Result ] The results showed that when the water temperature is 13 - 15 C and pH 7.2 -7.5, nitrate removal rate of immobilized microorganisms could sustainably achieve 90%, COD removal rate was also maitained at 80%; nitrate removal rate of zero-valent iron and activated carbon reaction medium maitained 50%, COD removal rate was 15 % -30%. [ Conclusion ] The removal rate of Immobilized microorganisms was higher and better. so the PRB with immobilized microorganisms as reaction media had potential applications for the treatment of nitrate polluted groundwater.关键词
