A process for purification of waste water from biogenic elements comprises the mechanical purification on grids, sand catchers and primary settlers, biological treatment with active sludge, which is carried out in anaerobic and aerobic zones in aerotanks. In the anaerobic zone the process is carried out at stirring of waste water with sludge mixture, taken at the outlet from aerobic zone, separation of the active sludge from water in the secondary settler, returning of the sludge for biological treatment. The anaerobic zone is placed in the basin of primary settler. The returning of active sludge is carried out at the beginning of aerobic zone.
