The chemical washing method is a technological process for removing odor by utilizing the chemical reaction of strong alkali or strong acid and malodorous substances such as hydrogen sulfide or ammonia gas and the like to generate salt substances. The treatment effect mainly depends on the usage amount of the alkali liquor or the acid liquor. The method has the disadvantages that the equipment and the pipeline are easy to corrode, the produced by-product sodium sulfide needs to be transported out, the cost is increased, and the alkali liquor or the acid liquor needs to be replenished periodically. In addition, in order to prevent the sprayed alkali liquor or acid liquor from scaling or hardening in the treatment device during operation, a strong spray pipe needs to be arranged in the treatment device, and the filler in the treatment device is regularly washed with high strength, so that secondary pollution is easily caused, the maintenance and repair amount is large, and the management difficulty is increased. The method is generally used to treat the system head-end as a pre-treatment process.
