摘要

  • 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 mol-ratio of Fe and EDTA. The suitable experiment condition was current of 1.0 A, initial catholyte pH of 5.6 and adequate molratio of Fe and EDTA. Fe nanoparticle and EDTA could be simultaneously and high efficiently recovered by diaphragm electrolysis combining with membrane treatment system.
