【 摘 要 】

New options are proposed for the modernization of existing air purification systems using know-how in the wastewater treatment plants themselves and in the area of their location. For air purification, it is proposed to use a new highly effective sorbent material, which is a claydite, covered with a thin layer of pyrolusite (manganese dioxide). This sorbent, which is in a wet state, oxidizes organic and inorganic toxicants on its surface, and also destroys pathogens. The proposed sorbent material is a natural formation obtained from the available raw materials approved for use for which additional permits are not required. Currently on the market there are no direct analogues of this product. Especially it is necessary to note a low cost of a new highly efficient sorbent material. In modern conditions, as a result of the increasing exploitation of water resources, the problems of human impact on the environment become particularly acute. These impacts, as a rule, are accompanied by factors that adversely affect the ecological state of the environment, both in the area of operation of the treatment facilities and in places far from them.
