[0002] Biological waste gas purification is a technology that uses biotechnology and chemical methods to purify waste gas containing harmful gases. It is mainly used in sewage treatment, garbage disposal, livestock and poultry farming and other industries. It can effectively reduce the emission of harmful gases and protect the environment and human health. The principle of biological waste gas purification is to use the adsorption, decomposition, conversion and other functions of microbial metabolism to convert harmful gases into harmless substances or reduce their concentration, thereby achieving the purpose of purification.
