预处理-氧化沉淀-曝气生物滤池组合工艺处理混合电镀废水的研究

摘要

探讨了预处理-氧化沉淀-曝气生物滤池(BAF)组合工艺处理混合电镀废水的可行性.结果表明:采用该组合工艺处理混合电镀废水具有一定的可行性；当水力停留时间为3h时,BAF对CODCr,CN-和Cu2+的去除率分别可达50％,83％和80％.%The feasibility of treating mixed electroplating wastewater with a combined process of pretreatment-oxidation precipitation-biological aerated filter (BAF) was explored. The results show that the method has a certain feasibility in treating mixed electroplating wastewater. When the hydraulic retention time (HRT) is 3 hours, after treatment by BAF, the removal of CODCr,CN- and Cu21 can reach 50 % , 83 % and 80 % respectively.
