The invention discloses a method for removing volatile organic compounds in coke oven coal charging waste gas, which comprises the following steps: by taking waste carbon powder as an adsorbent, mixing the waste carbon powder with the coke oven coal charging waste gas through a pre-spraying system of a coke oven coal charging waste gas ground dust removal station, adsorbing the volatile organic compounds in the coke oven coal charging waste gas, and removing the volatile organic compounds in the coke oven coal charging waste gas. And removing volatile organic compounds in the coke oven coaling waste gas. On the basis of the treatment thought of treating waste with waste, waste gas activated carbon powder generated by a desulfurization and denitrification activated carbon process is adopted as an adsorbent for removing VOCs, extra cost is hardly needed, meanwhile, an existing pre-spraying system of the coal charging waste gas ground dust removal station is utilized, extra transformation cost does not need to b
