1. combustion method: VOC waste gas is burned at high temperature and converted into harmless substances such as water and carbon dioxide. This technology has high treatment efficiency, but the equipment cost is high, and secondary pollution may occur.
2. Adsorption method: the VOC waste gas is adsorbed by adsorbent, and the adsorbate is regenerated to obtain the purification treatment of VOC waste gas. This technology has good fluidity and high treatment efficiency, but it needs professional knowledge in the selection and regeneration of adsorbents.
3. Catalytic oxidation method: VOC waste gas is converted into harmless substances by the action of catalyst. This technology can realize low temperature treatment with high treatment efficiency, but the selection and use of catalysts require professional knowledge.
4. Biological purification method: VOC waste gas is converted into harmless substances through the action of biological microorganisms. This technology is environmentally friendly, but the treatment efficiency is limited by environmental factors, so attention should be paid to the growth and operation of biological bacteria.
All the above technologies can effectively treat VOC waste gas, but the specific choice of which technology needs to be comprehensively considered according to the actual situation.
