When reconstructing left-bank sewage treatment plants, it is proposed to intensify the work of primary sedimentation tanks by including the acidification zone. When reconstructing aerotanks, it is expedient to allocate an anaerobic zone and a nitrification zone. The introduction of projected measures allows to reach the normative parameters of nitrogen and ammonium nitrogen and phosphorus discharge with an increase in the estimated flow rate to 460 thousand m3 / day.
