A plant for biological treatment of waste water contains a bioreactor of preliminary treatment, bioreactors of the first and second treatment stage and the settling tank. The bioreactor of preliminary treatment is equipped with the mean of water supply into the bioreactor of the first treatment stage and aeration mean. The bioreactor of the first treatment stage is equipped with the mean of water supply into the bioreactor of the second treatment stage, aeration mean and mean of the excessive active silt removal. The bioreactor of the second treatment stage is equipped with the agent for pumping of active silt mix into the bioreactor of the first treatment stage, aeration men and the mean for removal of treated water into the settling tank. At least, one of treatment bioreactors comprises a mean for pumping of active silt mix into the bioreactor of preliminary treatment. The settling tank is equipped with a mean of removal of treated water and a mean of removal of settled active silt. |
