Efficiency of using biological filtering material for environmental support of accelerated waste processing

Abstract

Based on the data obtained during the studies, the concentration of ammonia and hydrogen sulfide released during the accelerated processing of livestock waste was established. The design of an experimental setup for modeling the composting process using a biological air filtration system is presented. To ensure effective purification of air from ammonia and hydrogen sulfide generated during the accelerated processing of livestock waste, a method for using organic filter material consisting of compost and wood chips in various ratios is proposed. Also, the optimal time for cleaning air passing through the filter material has been established. The optimum type of filtering material and its characteristics have been experimentally established, ensuring the efficiency of air purification from hydrogen sulfide and ammonia by 97 and 98%, respectively.

Agroecological role of biohumus on sod-podzolic soil during irrigation of the rump-timothy grass mixture

“…Most of the natural meadows in Russia have low productivity, low quality of herbage. Hayfields and pastures are used haphazardly or removed from agricultural use [1][2][3][4][5]. It is possible to increase the productivity of meadows by improving them, for example, by introducing vermicompost, which is an organic fertilizer, obtained as a result of the processing of organic waste by worms under conditions of artificial cultivation [6][7][8][9][10][11][12].…”

“…They participate in multi-stage processes of decomposition of organic residues in the soil and their transformation into forms accessible to plants. [2,11].…”
