Abstract:

The iron-carbon micro-electrolysis packing was made by the method of calcination. The influences of clay, Fe/C mass ratio, clay proportion, packing diameter, additives and calcination temperature on the removal rate of simulated benzene groundwater were investigated. The results showed that the adsorption effect of clay after calcination was little; The optimum conditions of preparation for treating were Fe/C mass ratio 6∶1, clay proportion 25%, calcination temperature 300℃. The packing was used to treat BTEX groundwater, and the removal rate was over 80% after running steadily.

Key words: iron-carbon micro-electrolysis, packing, benzene, removal efficiency, groundwater
