Sewage treatment process and sewage treatment device |
| abstract |
The invention discloses a sewage treatment process and a sewage treatment device. The sewage treatment process includes: S10. Sewage is separately transported to an anaerobic tank and an anoxic tank in two ways, and the sewage in the anaerobic tank enters the anoxic tank after being treated. Deep denitrification; S20. The sewage in the anoxic tank flows out in two ways, one of which is returned to the anaerobic tank, and the other way passes through the anoxic aeration tank and the aerobic zone for full nitrification; S30. The sewage in the aerobic zone is divided into two The other way is input to the secondary sedimentation tank to separate the sludge and water to form sedimented sludge; S40. The sedimented sludge is returned to the sludge regeneration tank, and is aerated in the sludge regeneration tank to form active sludge. Sludge; S50. The activated sludge in the sludge regeneration tank is returned to the anoxic tank. The present invention can improve the activity of different target colonies in each area to achieve high-efficiency denitrification by performing multi-channel water inlet, multi-channel return, controlled aeration, conditioning and carbon increase treatment, and activation and reflux treatment of sludge. The gas process is more energy efficient. |
