Application status and prospects of biological deodorization in China

Abstract

With the development of urbanization, industry, agriculture and aquaculture, malodorous pollution has become increasingly serious. Odour pollutants can be produced by non-biological or biological pathways, which not only have a great negative impact on the regional ecological environment, but also cause great harm to the health of local people and animals. Compared with physical method, chemical method and adsorption method, biological deodorization method has the characteristics of high odour removal rate, environmental friendliness and low cost. Biological method is gradually becoming the preferred technique for odour removal in some odour producing areas. In this paper, the mechanism, the patent application status and the application prospect of biological deodorization are summarized and analysed, so that we can have a deeper understanding of biological deodorization.
