The results of the study of gas emissions from blocked wastewater treatment plants are presented. During the experiment, high concentrations of sulfur dioxide were detected. The analysis of methods for reducing the concentration of pollutants in the air of the working area of the aeration station was carried out. It is proposed to use a biochemical purification using a biofilter with a load of bark and biohumus. A model of the installation was constructed. To determine the technological parameters of the biofilter considered different types of combinations (height, moisture, particle size) of the carrier biomass and supporting layer of gravel, the effective processing time of the gas mixture. A decrease in sulfur dioxide, hydrogen sulfide, and formaldehyde was found. Additional advantages of the applied biologically active filter material are given.
