| 摘 要： | 通过制备不同组分改性膨润土,研究其对苯酚的吸附效果,结果表明,十六烷基三甲基溴化铵+十二烷基磺酸钠+硫酸铝-改性膨润土>十六烷基三甲基溴化铵+十二烷基磺酸钠-改性膨润土>十六烷基三甲基溴化铵-改性膨润土。通过改性膨润土对实际复杂组分渗滤液的吸附研究,结果表明,使用活性炭改性的膨润土吸附COD和NH4+-N最为理想,单位质量COD吸附量最高为26.8 mg/g,NH4+-N最高为3.92 mg/g,其中,COD最高去除率为77.3%,氨氮为28.9%;十六烷基三甲基溴化铵+十二烷基磺酸钠+硫酸铝-改性膨润土对COD和NH4+-N均有去除效果,两者对于渗滤液实际处理工程具有应用价值。 |

| 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 +bentonite>HTMAB+ C18H29NaO3S +bentonite>HTMAB+bentonite,and the sorption capacities of modified bentonites for COD and NH+4-N were acticarbon+bentonite>HTMAB+ 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. |
| Keywords: | modified bentonites adsorption phenol COD NH＋4-N leachate |
