| titleOfInvention | process and wastewater treatment unit comprising control of dissolved oxygen concentration |
| abstract | wastewater treatment process and unit comprising control of dissolved oxygen concentration. the present invention relates to a process for the treatment of wastewater that includes the steps of: a contact step, in which the wastewater comes into contact with bacteria trapped on a support surface and the concentration of dissolved oxygen in the water served is maintained at 2.0 mg / l or less; an aeration step, in which gas passes through the waste water that has passed through the contact step and the dissolved oxygen concentration of the waste water decreases as it passes through the aeration step; a sedimentation stage, in which the waste water that has passed through the aeration stage is substantially divided into treated water and sludge; and a sludge recycling step, in which the sludge from the sedimentation step passes to the contact step. the invention also relates to a processing unit in which it is possible to carry out the aforementioned process. |
