摘要
制备了锰粉改进的规整化微电解填料,采用电化学辅助改进微电解填料处理初始COD为6 153.6 mg/L、ρ(NH_3-N)为182.6 mg/L的焦化废水,优化了工艺条件。实验结果表明,电化学辅助微电解法处理焦化废水的最佳工艺条件为电压8 V,填料投加量20 g/L,初始废水pH 6,反应时间30 min。在此条件下废水COD去除率为75.3%,NH_3-N去除率为65.4%;在其他工艺条件相同的情况下,未通过电化学辅助的填料微电解反应的COD去除率为33.0%,NH_3-N去除率为16.2%,电化学辅助后的COD去除率和NH_3-N去除率均明显提高。
The regular manganese powder modified microelectrolysis packing was prepared, and the coking wastewater with 6 153.6 mg/L of COD and 182.6 mg/L of ρ（NH3-N） was treated on the modified microelectrolysis packing assisted by electrochemical method. The process conditions were optimized. The experimental results show that： Under the optimum conditions of electric voltage 8 V , packing dosage 20 g/L, initial wastewater pH 6 and reaction time 30 min, the removal rates of COD and NH3-N in the coking wastewater are 75.3% and 65.4% respectively; While those on the modified microelectrolysis packing without electrochemical assistance are 33.0% and 16.2% under the same conditions. With the help of electrochemical assistance, the removal rates of COD and NH3-N are both increased significantly.
