  • 摘要: 在研究填充介质配比的基础上，考察中砂-膨润土-微生物构成的可吸附生物反应墙对模拟地下水中不同浓度BTEX（苯、甲苯、乙苯和二甲苯）的去除效果，并通过添加硝酸盐考察电子受体对地下水BTEX去除效率的贡献。结果表明，膨润土/中砂的最佳体积比为20：80，此时渗透性反应墙的渗透系数为2.01×10-5 m/s，有效孔隙率为16.71%。添加硝酸盐的生物反应墙对不同浓度下BTEX的去除率较为稳定，没有添加硝酸盐的对照组对BTEX的去除效果波动较大。在进水浓度分别为6、8和10 mg/L时，添加硝酸盐的生物反应墙和对照组对BETX的总去除效率分别约为94%、91%，96%、90%，97%和87%。可吸附生物反应墙对BTEX有较好的去除效果，添加硝酸盐对去除BTEX有一定的促进作用。
    Abstract: Adsorptive biological reactive wall comprising medium sand-bentonite-microorganism for removing simulated groundwater BTEX (benzene,toluene,ethyl benzene,xylene) of different concentrations was investigated with the variance of filling media ratio,and the dependence of BTEX removal efficiency in groundwater on electron acceptor was also studied through adding nitrate.The results show that the optimum volume ratio of bentonite-medium sand is 20:80,with a permeable reactive wall permeability coefficient of 2.01×10-5 m/s and effective porosity of 16.71%.The addition of nitrate to biological reactive wall stabilized BTEX removals under different concentrations,comparatively,while the control group without nitrate exhibited volatile BTEX removal efficiency.Under conditions of influent concentrations of 6,8 and 10 mg/L,the BETX removal rates of biological reactive wall with/without the addition of nitrate and the control group are about 94%/91%,96%/90%,and 97%/87%,respectively.The adsorptive biological reactive wall shows significant performance on BTEX removal,especially with the aid of nitrate additive.
