聚氯化铝混凝剂的绿色化学观——中日聚氯化铝混凝剂的比较

摘要

用绿色化学原理全面评价了中国、日本生活饮用水用聚氯化铝(PAC)混凝剂,从产品的生产原料、工艺流程、技术标准、产品质量、生产成本、应用效果及产生的固体废弃物等方面阐述了两国PAC混凝剂的差异和各自存在的问题,提出了相应的解决方案,指出了聚氯化铝混凝剂未来的绿色发展之路.%Polyaluminium chloride (PAC)coagulants used for drinking water in China and Japan were completely evaluated with green chemistry principles.The differences and problems of PAC coagulants in the two counties were introduced from 7 aspects,such as raw materials,process flow,technical standard,product quality,production cost,application effect,and produced solid waste.Corresponding solutions were put forward for the problems and the future green development road for PAC coagulants was also pointed out.
