富含活性氯与Al13水处理药剂对铜氰络合物去除效能

含重金属铜离子与氰离子(CN)的络合物广泛存在于电镀、冶金等工业废水中,是一种较难处理的污染物。富含活性氯和Al13聚合体的水处理药剂(PACC)兼具氧化和絮凝效能,在处理含重金属氰络合物([Cu(CN)3]2-)废水方面具有良好的应用前景。研究PACC与[Cu(CN)3]2-的反应计量学、动力学,考察了pH、反应时间和投药量等影响因素,确定PACC的最佳工作参数。结果表明,PACC可同时实现对CN的氧化和对Cu2+的絮凝,有效去除水中[cu(CN)3]2-使用PACC对[Cu(CN)3]2-的无害化处置过程分为2个阶段:CN-首先被氧化成氰酸根(OCN);然后OCN-被进一步氧化并生成碳酸氢...

Copper cyanide complexes ( [ Cu(CN) 3 ] 2- ) are produced in several types of industry that in- clude electroplating, mining, and they are difficult to be removed from wastewater. A novel water treatment reagent containing high content of active chlorine and All3 polymer (PACC) was prepared by electrochemical method. PACC has shown a promising potential for the removal of metal-cyanide complex due to the combined functions of oxidation and coagulation. In order to determine the optimal working conditions of PACC, stoichiometry and kinet- ics of the reaction between PACC and [ Cu (CN) 312
