Prospects for biotechnology in wastewater processing at coke plants

Resumo

The prospects for biotechnology in wastewater processing at coke plants are considered, in conditions of nitrification and denitrification. Wastewater-processing systems employed at Russian and foreign coke plants are compared. The degree of purification is about the same in Russia and elsewhere. However, the treated water does not meet Russian standards for delivery to municipal treatment plants and reservoirs from which fish are taken to be cooked. The single-phase AO VUKhIN biotechnology permits the removal of 80–90% of the nitrate present without the addition of organic reagents, in contrast to classical nitrification and denitrification technology.
