The activated carbon adsorption tower is the best purification equipment for dealing with organic waste gas and odor treatment. Activated carbon adsorption is an effective way to remove the odor of water, natural and synthetic dissolved organic matter, micro polluting substances and so on. Most of the larger organic molecules, aromatic compounds can be firmly adsorbed on the surface or voids of the activated carbon,The results showed that humus, synthetic organic matter and low molecular weight organic matter could be removed effectively .Adsorption of activated carbon as the depth of purification process, often used in the last stage of waste water treatment, but also can be used for producing long water, purified water of life. When the dust particles and more, activated carbon adsorption device can simultaneously and water curtain machine and water spray tower and UV plasma used together to discharge waste gas purification.
