Using iron filings, activated carbon power and clay as raw materials, the granular iron-carbon micro-electrolysis packing was made by the method of calcination. The influence of initial chlorobenzene (CB) concentration, pH value and reaction temperature on the removal rate of simulated wastewater containing CB were investigated. The results showed that the reaction followed the pseudo-ﬁrst-order kinetics model and the rate constants varied at a relatively low degree at various pH. Temperature is an important parameter and an increase in temperature could signiﬁcantly raise the reaction rates. The column packed with packing was designed to remove CB in wastewater. After running for 70 days, the packing still had good performance and there was no obvious decrease on the removal rate.
