| 摘 要： | 采用电混凝-反渗透组合工艺处理渗滤液经膜生物反应器的出水,考察组合工艺的处理效果及电混凝作为RO进水预处理的可行性。结果表明,组合工艺出水COD和NH3-N、TP的质量浓度分别为100 mg/L和20、0.2 mg/L,去除率分别达到95%、90%、98%,可以满足GB 16889-2008的排放要求;出水电导率为355μS/cm,膜出水电导率与进水电导率的比大于0.94。电混凝工艺能够有效降低RO进水的COD、TP含量,明显地减缓膜结垢污染,改善膜的产水率,可以作为膜前预处理。

| Abstract: | The treatment of landfill leachate after biochemical methods by electrocoagulation-reverse osmosis membrane was investigated in order to check the efficiency of the combined process and the possibility of electrocoagulation as pretreatment.It is found that the combined process achieved 95% removal efficiency for COD,90% removal efficiency for NH3-N and 98% removal efficiency for TP,and COD,NH3-N and TP in effluent were less than 100 mg/L,20 mg/Land 0.2 mg/L respectively,which satisfied leachate effluent with discharge standard GB16889-2008.The conductivity was less than 355μS/cm.COD,TP and conductivity of RO influent was effectively reduced and membrane flux was improved by electrocoagulation pretreatment which could serve as RO membrane pretreatment technology. |
