[0002] Volatile organic compounds (VOCs) are a class of volatile organic compounds that are commonly found in various industrial processes and products in life, such as paints, detergents, inks, glues, etc. These compounds are harmful to human health and the environment, so they need to be treated. VOCs treatment equipment is a type of equipment used to purify VOCs in the air, usually including processes such as adsorption, oxidation, and biological treatment. Through these processes, VOCs are converted into harmless substances or their concentrations are reduced, thereby achieving the purpose of purifying the air.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "VOCs treatment device" with the application number "CN202321305374.5". The patent mainly uses an incinerator and an air inlet pipe. An air inlet is provided on the side wall of the incinerator. The air inlet pipe is connected to the air inlet. A through hole is provided on the top wall of the air inlet pipe. A sealing plate is rotatably connected to the outside of the through hole. Fixed plates are respectively installed on the inner walls on both sides of the air inlet pipe, and a filtering mechanism is installed between the two fixed plates.

[0004] However, the filter in the device needs to be replaced or cleaned frequently to maintain its effectiveness, which increases the maintenance cost and operational complexity of the equipment. Especially when treating a large amount of VOCs, the frequency of replacing the filter may increase. In addition, the filter can only physically capture VOCs and cannot chemically degrade them, so the treatment efficiency is low, especially for low-concentration or diluted VOCs. To this end, we propose a composite microbial treatment device for VOCS. Utility Model Content
