| 摘 要： | 以涂Ir/Sn钛网板作阳极,以不锈钢网板作阴极,采用隔膜电解法处理电厂锅炉EDTA清洗废水.实验结果表明,电流、阴极电解液初始pH值和Fe/EDTA摩尔比对粉末铁析出速率影响较大,粉末铁电解析出的适宜条件是电解电流为1.0 A、阴极电解液初始pH值为5.6、阴极电解液Fe/EDTA摩尔比足够高.采用隔膜电解结合反渗透膜系统处理电厂锅炉EDTA清洗废水,可同时高效回收纳米级粉末铁和EDTA.

| Abstract: | Recovery of EDTA boiler cleaning wastewater from power plant by diaphragm electrolysis was studied. The titanium coated with iridium/stannum oxide and stainless steel were used as the anode and cathode, respectively. The deposition speed of Fe powder was mainly influenced by current, initial catholyte pH and toolratio of Fe and EDTA. The suitable experiment condition was current of 1.0 A, initial catholyte pH of 5.6 and adequate tool-ratio of Fe and EDTA. Fe nanoparticle and EDTA could be simultaneously and high efficiently recovered by diaphragm electrolysis combining with membrane treatment system. |
