Abstract
The invention discloses an aerobic activated sludge mud-water separation device. The device comprises a plurality of sleeved separators, wherein each separator comprises a solid-liquid separator and a plurality of barrels; each solid-liquid separator is provided with an air duct; the lower end of each barrel is provided with a baffle; each solid-liquid separator is a hollow cone; the lower end ofeach solid-liquid separator is connected with an edge; a water inlet is arranged between each solid-liquid separator and each barrel; and the barrels are connected through water outlet pipes. The device has compact structure and small floor space; a sludge reflux system is not required, the energy consumption is reduced, the excess sludge can be directly discharged from the aeration tank; and thedevice has high practical application value.
Description
technical field [0001] The invention relates to an aerobic activated sludge sludge-water separation device, which can replace a secondary settling tank as a sludge-water separation device for activated sludge in an aerobic aeration tank, and realize the integrated design of the aeration tank. Background technique [0002] In the sewage treatment system, the separation of sludge and water is usually achieved by setting up a sedimentation tank. However, a sludge return system needs to be installed at the bottom of the general sedimentation tank, which increases energy consumption. When the amount of waste water to be treated increases and the project is transformed, it is often necessary to add a secondary settling tank, which will lead to an increase in cost. [0003] Utility model patent 01214672.2 discloses a flat multi-grid sedimentation settler. It is structured like this: the bottom of the settler is flat, and several partitions are installed to form a mud discharge ch...
