Оценка активированного угля марки аг-3 для доочистки биохимочищенных сточных вод КХП

Abstract

The post-treatment of bio-treated wastewater of the CCP with activated carbon (AU) of the AG-3 brand from pollutants causing bichromate oxidizability (COD) was investigated. It is shown that the grinding of granulated coal reduces its consumption for the post-treatment of wastewater by ~ 7 % and eliminates its color. It has been established that granulation, used in the production technology of AG-3 grade AU based on semi-coke dust, reduces the sorption efficiency of high-molecular compounds of folic and humic acids.
