According to the VOC treatment system and method in the coking production process, the adsorption performance of coke powder is fully utilized, the collected coke powder is used for adsorbing VOC in coke oven flue gas, the coke oven flue gas is purified and treated, and unorganized emission of VOC in the coking production process is reduced. According to the treatment system, on the basis of original coke powder collection, the VOC capturing function is added, the captured coke powder is used for adsorbing VOC, synchronous purification treatment of the coke powder and VOC in the coking production process is achieved, the coke powder enriched with VOC is sent to a blast furnace to be blown or used for sintering combustion, and internal circulation of the coke powder in the whole steel production flow system is achieved. The VOC treatment system disclosed by the invention is small in occupied area, small in construction investment, low in operation cost, economical and environment-friendly, and very wide in pop
