摘要:针对电荷调节剂生产废水 COD 高,色度高,可生化性差的特点,采用微电解- 水解酸化- SBBR 处理工艺进行研
究。实验结果表明: 在微电解铁碳比为 1∶1 5 ,反应停留时间1 h ,水解酸化水力停留时间为9 h , SBBR 曝气量为
0 25 L min ,曝气时间8 h ,静沉1 5 h ,该工艺最终出水各项水质指标能够达到进入市政污水管网的要求。

Abstract: According to the charge regulator wastewater which features high concentration of COD , high chroma and poor
biodegradation , the waste water is pretreated by the process of microelectrolysis hydrolytic acidification SBBR. The experimental
results show that when the ratio of Fe C is 1∶1 5 , the reaction time is 1 h , acid hydrolysis of HRTfor 9 h , the reaction conditons of
SBBR are quantity of the aeration is 0 25 L min , time for aeration is 8 h , time for sedimentation is 1 5 h , the effluent quality can
meet the requirements for municipal sewage s.
