Results of studies on biological wastewater treatment of a brewery

Abstract

For the biological treatment of wastewater from the brewing industry, a batch reactor was used, which was operated under aerobic and anoxic-aerobic conditions. As a result of long-term studies, the following qualitative characteristics of treated wastewater were achieved, mg/l: COD 147, BODtot 36, suspended solids 10. Nitrogen compounds were reduced to, mg/l: N-NH4 0.68, N- NO3 15.3, N-NO2 0.01. The specific rate of oxidation of organic pollutants at 20 C averaged, mg/(gh): for COD 12.4, for BODtot 9.
