Odor gas treatment - biological drip filtration tower

Biological drip filtration towerThe structure is similar to that of a biological filtration tower, but the difference is that it is equipped with a spray device at the top, and the humidity inside is controlled by it. The liquid sprayed through the filter bed drips down. The spray solution often contains nutrients necessary for microbial growth, and the porosity of the filter material filled with it is usually required to be higher than that of the biological filtration tower.

Principle of Biological Treatment of Organic Waste Gas

Biological methods utilize microorganisms to degrade and metabolize organic matter into inorganic matter for wastewater treatment. By artificially creating an environment suitable for the survival and reproduction of microorganisms, they can multiply in large quantities to improve their efficiency in oxidizing and decomposing organic matter. According to the type of microorganisms used, it can be divided into aerobic, anaerobic, and enzymatic methods.

Biological method is a waste gas treatment method developed based on the metabolic mechanism of microorganisms and considering the characteristics of organic gases themselves. It has the advantages of no secondary pollution, large treatment capacity, low operating costs, good purification effect, and low energy consumption. There are mainly biological energy towersBiological drip filtration towerThe devices and processes for treating organic gases using biological methods such as biological scrubbing towers, membrane bioreactors, and activated sludge.

Biological drip filtration towerApplication in the treatment of odorous gases

Odorous gases not only have a serious impact on the ecological environment, but also pose great harm to human health, causing central nervous system disorders and lesions, and leading to chronic and acute diseases. Heterocyclic spices have a low threshold, high odor intensity, and unpleasant odor. During production and packaging, a large amount of odor is easily released, which can cause physical and mental discomfort to both internal and surrounding personnel of the company.

The exhaust gas generated by the factory has a low concentration, complex composition, difficult monitoring, and difficult treatment. Research on the treatment of odorous gas pollution began as early as the late 1950s abroad, and accumulated rich theoretical knowledge and practical experience. China only conducted research on the investigation, testing, and standardization of odorous gas pollution in the 1980s, while research on deodorization technology began in the 1990s.
