Polishchuk A. Denitrification of city wastewater in corridor aeration tank

Constructed and realized more general mathematical model of denitrification process. The ground analysis of influence of organic matter, nitrate nitrogen and other factors on denitrification process is carried out. On the basis of the received of theoretical and experimental results of researches of denitrification of city wastewater in corridor aeration tank the expressions for calculation of internal recirculation coefficient for mix water-sludge effluent from the end of nitrification volume to the beginning of denitrification zone are obtained. More perfect technological scheme of complex treatment of city wastewater from biogenic elements in corridor aeration tank is offered. The procedure of engineering calculation of technological parameters for denitrification process, and also for aeration tank, which work under the offered technological scheme, is developed.
