有机膨润土在水玻璃旧砂湿法再生污水处理中的应用研究
Study on Application of Organobentonite to Wastewater Disposal of Wet Reclaiming Used Sodium Silicate Sand
摘要
Abstract
The advantages of wet reclaiming used sodium silicate sand include higher removing residual binder rate and better reclaimed sand quality; but the main disadvantage possesses the problem of wastewater treatment and its recycling use.Using Liangzi Lake district bentonite in Ezhou, HuBei as raw material, the authors make the organobentonites and combine it with polyaluminium chloride using to used sodium silicate sand wet reclaiming wastewater treatment, and obtain satisfactory effect.The paper discussed the wastewater disposal effect factors including the wastewater's pH, the organobentonites concentration and the proportion of organobentionites to polyaluminium chloride, and the better technical parameters using the organobentonites dispose the wastewater were obtained by orthogonal experiment.关键词
