超濾膜去除地下水中硝基苯的試驗研究
摘要: 為解決持久性有機污染物對地下水造成的污染,以硝基苯為研究對象,考察了超濾膜對硝基苯的去除效果及影響因素.試驗結(jié)果表明,當進水硝基苯濃度為85 μg/L,超濾膜可以連續(xù)工作68 h,出水小于17 μg/L.地下水中鐵、錳離子對去除效果沒有顯著影響.進水硝基苯濃度對去除效果有顯著影響.當進水硝基苯濃度由85 μg/L上升至340 μg/L時,超濾膜連續(xù)工作時間急劇下降,僅為14 h;對由硝基苯引起的膜污染,2% CH3CH2OH清洗效果最佳.作為一項應(yīng)急處理技術(shù),該工藝可以保障小城鎮(zhèn)地區(qū)飲水安全. Abstract: In order to solve the pollution of groundwater caused by persistent organic contaminants,the removal efficiency and affecting factors of nitrobenzene removal from groundwater by using ultrafiltration technology was investigated.The experimental results indicate that the ultrafiltration system can work continuously for 68 hours when initial concentration is 85μg/L,and the nitrobenzene concentration of outflow is less than 17μg/L.Fe and Mn in groundwater have no significant impact on the removal efficiency,but the effect of initial nitrobenzene concentration of inflow is obvious.The continuous operation time decrease sharply from 68 to 14 hours when nitrobenzene concentration is 340 μg/L.2% CH3CH2OH has the best performance for cleaning the fouling caused by nitrobenzene.As an urgent treatment technology,ultrafiltration technology could guarantee the security of drinking water for people living in rural area. 作 者: 趙玉鑫 尹軍 王曉玲 劉蕾 ZHAO Yu-xin YIN Jun WANG Xiao-ling LIU Lei 作者單位: 趙玉鑫,王曉玲,劉蕾,ZHAO Yu-xin,WANG Xiao-ling,LIU Lei(哈爾濱工業(yè)大學市政環(huán)境工程學院,黑龍江,哈爾濱,150090)尹軍,YIN Jun(哈爾濱工業(yè)大學市政環(huán)境工程學院,黑龍江,哈爾濱,150090;吉林建筑工程學院環(huán)境工程系,吉林,長春,130021)
