The possibility of increasing the efficiency of
municipal wastewater treatment plant (WWTP) operation by
changing the flow diagram of biological wastewater treatment
in aeration tanks at minimum expenses for their reconstruction
is shown in the paper on the example of one of the regional
centres of Ukraine. The technology of nitri-denitrification of
wastewater according to the flow diagram of the two-stage
modified Ludzak-Ettinger process is offered for the considered
conditions. The distribution of wastewater flows and internal
nitrate recycling between the individual stages of this flow
diagram has been optimized in order to minimize the residual
content of total nitrogen in the treated effluents. Computer
dynamic modelling of biochemical processes has proved the
high efficiency and reliability of the flow diagram proposed by
the authors.
