摘要
以煤矸石为原料制备了高效絮凝剂-聚合氯化铝(PAC),确定了制备PAC的最佳反应条件,并对其进行了处理废水实验。结果表明,由煤矸石为原料制得的产品聚合氯化铝比市售PAC处理废水效果更佳。
A practical method for the preparation of polyaluminum chloride from coal gangue was reported. The optimum reaction conditions for the preparation of polyaluminum chloride, including reaction temperature, reaction time, concentration of reactants and molar ratio of reactants, were determined. The results of the coagulation-flocculation experiments for treating wastewater show that the performance of APC prepared from coal gangue is much better than that of commercial PAC.
