The utility model relates to a waste gas treatment device for a scouring pad oven, which is used for treating waste gas generated in oven process in scouring pad production step by step. With the adoption of the waste gas treatment device for the scouring pad oven, the defect that the waste gas treatment device in the prior art is not suitable for treatment of scouring pad waste gas. The treatment device comprises a first-level alkaline tower, a secondary-level alkaline tower and a third-level water spray tower which are sequentially arranged according to a waste gas route, wherein the third-level water spray tower is connected with an emptying device. A circulating device comprises a first-level alkaline solution circulating device corresponding to the first-level alkaline tower, a secondary-level alkaline solution circulating device corresponding to the secondary-level alkaline tower and a third-level water circulating device corresponding to the third-level alkaline tower. The oven waste gas generated in scouring pad oven production process is respectively treated by an oven waste gas treatment system, the oven waste gas is absorbed by the alkaline towers twice and is absorbed by the water spray tower once according to the content of particulate matters and organic matters in the oven waste gas, the treatment effect is good, and the treated waste gas can reach national emission standards.
