| 摘 要： | 研究基于再生水回灌地下、补充地下水水源的目的,使用河南信阳某膨润土厂生产的钠基膨润土,通过酸改性、铝柱撑改性和微波-硫酸亚铁改性制得三种改性膨润土,用于处理城市污水处理厂的二级出水.实验结果显示,经XRD衍射分析可知,三种方法制备的改性膨润土,其矿物结构都有不同程度上的变化,膨润土层间距都较膨润土原矿有所增大,可见其改...

| Abstract: | Based on the purpose of groundwater recharge by using reclaimed wastewater,several kinds of modified bentonite including acid modification,Al-pillared modification and microwave-ferrous sulfate modification from a bentonite factory of Xinyang,Henan Province were used for the treatment of secondary effluent water from a wastewater treatment plant.Results showed that after different kinds of modification,the mineral structure of modified bentonite was changed.Under the analysis of XRD,the spacing of the modif... |
