【摘要】 Mg2+在pH9.5～11.5时可以形成氢氧化镁沉淀,所形成的氢氧化镁沉淀对废水中的污染物质具有很好的絮凝效果,因而近年来得到国内外研究人员的广泛重视。作者全面论述了镁化合物(氯化镁、氢氧化镁、海水、卤水、干卤等)在水处理中的研究应用现状,展望了其在工业废水处理中的应用前景。更多还原

【Abstract】 When magnesium ion is initially present in wastewater,an increase in pH upon alkalization will result in the precipitation of magnesium hydroxide.The resulting magnesium hydroxide is a gelatinous precipitate,which has been found to serve as an efficient coagulant and flocculant aid.Over the past years,the role of magnesium ions as a potential flocculant for the chemical clarification of wastewater have been investigated.A comprehensive review of high pH magnesium flocculant application in wastewater treatment and the development trend in the future are presented.更多还原
