Abstract
The invention discloses a centralized biological aerobic sedimentation tank, which is characterized in that a mixing and stirring area is equipped with a sludge hoist, which is connected with a condensed sludge discharging area. A sludge discharging pump which is connected with the condensed sludge discharge area is arranged in a main tank body, which is also equipped with an aeration pipe inside. All parts of the invention closely match through pipelines. Compared with other sedimentation tanks and clarification tanks, the invention is provided with more reasonable structure and more even water distribution to realize the complete slurry body circulation. An aeration system provides sufficient dissolved oxygen for sludge microorganism in the tank to strengthen the biological effect. Various reagents inside and outside the tank body are added at a plurality of points to further strengthen the physical flocculation. A lifting mixer and the sludge hoist are controlled by a variable-frequency motor and can be flexibly regulated according to practical using situations to further ensure the effluent quality. A mud scraper at the bottom can both centralize and concentrate the sludge and is applied to the strengthening of the conventional treatment, the sewage plant treatment and special water treatment of water supply plants.
