Description

Technical Field

[0001] The utility model relates to the technical field of aeration and flow guiding devices, in particular to an aeration and flow guiding device applied to an ecological filter tank. Background Art

[0002] Aerated biological filtration technology appeared in Europe in the early 1980s. Its outstanding feature is that it combines biological oxidation and filtration on the basis of primary enhanced treatment. There is no sedimentation tank after the filter tank, and the system is operated periodically through backwashing and regeneration. Due to the good performance of aerated biological filtration technology, its application scope has been continuously expanded. After experiencing a large development in the middle and late 1980s, this process has basically matured in the early 1990s. In the secondary or tertiary treatment of sewage, aerated biological filtration technology has the characteristics of high treatment load, good effluent water quality, and less land occupation. After the 1990s, aerated biological filtration technology has developed rapidly and derived a variety of process types.

[0003] The current publication number CN209668872U discloses a diversion aerated biological filter tank including an inner cone area provided with an inlet pipe, an outer cone area provided with an outlet pipe, a lower diversion sedimentation pumpless sludge return area and a sludge discharge pipe arranged at the bottom, wherein a sludge discharge valve is provided on the sludge discharge pipe, and a sludge partition is provided above the sludge discharge pipe in the lower diversion sedimentation pumpless sludge return area, the sludge partition divides the lower diversion sedimentation pumpless sludge return area into a sedimentation area and a reflux area, the sludge partition includes a plurality of movable fans and fixed fans, and also includes a movable fan moving mechanism for moving the movable fan to open or close the sludge partition. The lower diversion sedimentation pumpless sludge return area is divided into a sedimentation area and a return area by a mud separator. When sludge discharge is required, the sludge at the bottom of the filter tank is separated from the wastewater in the filter tank, and then the sludge discharge valve is opened to discharge the sludge through the sludge discharge pipe. The sedimentation area has a conical structure, which is convenient for sludge gathering, and the sludge discharge is more thorough, with less sludge mixed with wastewater, and the subsequent sludge drying is convenient for treatment.

[0004] In order to solve the problem of aeration and diversion of ecological filter tanks, the existing technology uses partitions to divide the area and uses a conical sedimentation tank for sludge discharge. However, there will still be insufficient aeration and insufficient filtration and purification of water, which will lead to poor aeration performance, insufficient dissolved oxygen in water, and inadequate water purification.
