Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a comprehensive treatment system for malodorous organic waste gas. Background technique [0002] At present, malodorous gas has been recognized by countries all over the world as a typical environmental hazard. In recent years, my country has also begun to pay attention to the monitoring and prevention of odorous gases, and has formulated the emission standards of odorous pollutants (GB14554-93) and supporting analysis methods. In addition to hydrogen sulfide and ammonia, most of these malodorous gases are VOCs (volatile organic compounds). According to the emission standard of odor pollutants (GB14554-93), the key control items include ammonia, trimethylamine, hydrogen sulfide, methyl sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide and styrene. These malodorous substances have a low olfactory threshold and can enter the human body through cont...

Problems solved by technology

The chemical absorption method can only absorb acidic or alkaline substances. Although the purification efficiency is general, the chemical cost is high and the operating conditions are harsh; the adsorption method is simple in process, but the disadvantage is that the cost is too high and the activated carbon needs to be replaced regularly; Plant gas or fuel oil is used to support combustion, which increases operating costs and causes secondary pollution to the environment; biological methods are relatively new, but still require additional additives as element supplements, and generally need one to two years to replace the strains. There are requirements on the stability and concentration of the ingredients
