改性膨润土对垃圾填埋场渗滤液吸附效果
Adsorption efficency of modified bentonites for landfill leachate
摘要
Abstract
Researches on the adsorption for phenol and leachate containing real multi-components by modified bentonites synthesized(singularity or complex) with bentonite and the addition of C19H42BrN(HTMAB) or C18H29NaO3S or Al2(SO4)3 and acticarbon as modifiers were carried out.Test results shows that the sorption capacities of modified bentonites were HTMAB+ C18H29NaO3S +Al2(SO4)3 +bentoniteHTMAB+ C18H29NaO3S +bentoniteHTMAB+bentonite,and the sorption capacities of modified bentonites for COD and NH+4-N were acticarbon+bentoniteHTMAB+ C18H29NaO3S +Al2(SO4)3 +bentonite.The maximum values of COD and NH+4-N adsorpted by modified bentonites were 26.8 mg/g and 3.92 mg/g,respectively.The maximum percentage COD and NH+4-N removed from leachate acount for 77.3% and 28.9%,respectively.Both acticarbon+bentonite and HTMAB +C18H29NaO3S+Al2(SO4)3+bentonite are applicable for leachate treatment.关键词
