Abstract
The use of industrial wastes as alternative adsorbents for wastewater treatment is proposed. The effective concentration of the adsorbent was determined experimentally. The results of a study of the intensification of biological wastewater treatment using activated carbon and a pulverized coke fraction are presented. The efficiency of treatment in terms of "chemical oxygen demand" during the intake of highly concentrated sewage sludge with the use of an alternative adsorbent averaged 85 %. In the biosorption system, the conservation of the species diversity of the biocenosis of activated sludge and its purifying ability was noted. In the biological treatment system, purification efficiency was recorded on average 16 % less and destabilization of the system as a whole. The carried out researches prove expediency of use of adsorbents, including production wastes, for intensification of biological wastewater treatment in aero tanks.
