【摘要】 研究了高铁酸盐氧化絮凝去除水中藻类的机制.结果表明,高铁酸盐的强氧化性对藻类呼吸作用和生长方式有影响,同时其还原产物Fe(OH)3对藻类有絮凝作用,因此高铁酸盐对水中藻类的去除是氧化和絮凝协同作用的结果.采用聚合氯化铝(PAC)作絮凝剂,投加少量高铁酸盐可以明显地影响藻类细胞表面的电动电势,强化PAC的电位和絮凝效果.更多还原

【Abstract】 The mechanism of algae removal in water with ferrate oxidation-coagulation was studied. The results show that the strong oxidizability of ferrate influences on the breach and the growth of algae, at the same time, its reduction product Fe(OH)3 possesses the function of coagulation on algae. Therefore, the removal of algae in water is the result of the cooperation of its oxidation and coagulation. Using polyaluminum chloride (PAC) as coagulant with input of little amount of ferrate could influence markedly the electromotive force (EMF) of the algae cell surface and strengthen the efficiency of EMF and coagulation.更多还原
