Abstract

The issues of optimization of aerobic biological wastewater treatment processes are considered. Optimal ratios of characteristics and sizes of primary and secondary sedimentation tanks, as well as their relationship with the concentration of activated sludge by volume, are revealed. Graphical representations of the dependence of the volumes of primary, secondary and total volumes of structures on the concentration of activated sludge in cleaning processes with low and high loads are obtained. Experimental studies have shown that the concentration of activated sludge in the aeration tank and the silt index directly affect the deposition characteristics of activated sludge, in particular the hydraulic surface load (upward flow velocity).
