Abstract
The circulating micro-electrolysis process with aeration was employed for pretreatment of coking wastewater.The experiment results showed that color removal and COD removal were 100% and 77.6%,respectively,when aeration flow was 5 m3/h,circulating time was 4 h,pH value was 3,and wastewater flow was 1 L/min.And the B/C in coking wastewater increased from 0.18 to 0.38.
