Abstract

A combined treatment technology for biochemical odors comprises steps as follows: (1) biological deodorization: malodorous gases pass through biological deodorization equipment containing combined filler, microorganisms are attached to the inert filler, the temperature is kept at 16-30 DEG C, and biological decomposition is performed; (2) catalytic oxidation: the gases in the Step (1) are introduced into a catalytic oxidation spray tower, and a strong oxidant is supplemented to spray water continuously; (3) adsorption: wastewater after catalytic oxidation passes through a corrugated board water-removal layer and then enters an activated carbon adsorption tower for adsorption; (4) exhausting: waste gases after adsorption enter an exhausting chimney for exhausting. According to the technology, the deodorization efficiency is up to 99%, the ability for treating various malodorous waste gases is high, and multiple industrial waste gases can be treated simultaneously.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a biochemical odor combined treatment process. Background technique [0002] In recent years, people have gradually realized the great harm of odorous exhaust gas to the environment and human health, so people pay more and more attention to the treatment of odorous exhaust gas in the field of environmental engineering. [0003] At present, the treatment of malodorous exhaust gas mainly adopts physical and chemical methods, such as combustion, adsorption, absorption and reduction. The process or equipment of these methods is more complicated, and the operating cost is higher; when used to treat some malodorous exhaust gases, the effect is not very satisfactory. [0004] The comparison table of advantages and disadvantages of biological deodorization technology is as follows: [0005] [0006] There are some deficiencies that need to be solved: such as changes in a...
