A seepage-preventing type aerated biofilter is disclosed. The aerated biofilter includes an aerated biofilter main body. The bottom of the main body is paved with a geosynthetic clay liner. Two sidesof the main body are provided with a second water distribution tank and a first water distribution tank. Four pedestrian paths are disposed in the main body at an equal interval, and divide the insideof the main body into three aeration chambers which are a first aeration chamber, a second aeration chamber and a third aeration chamber. The first, second and third aeration chambers are communicated with each other. Two sides of each of the four pedestrian paths are provided with tempered glass. The aerated biofilter is provided with the pedestrian paths provided with the tempered glass, and therefore workers can walk in the pedestrian paths, observe water distribution and aeration situations in the first, second and third aeration chambers through the tempered glass, and can observe and acquire aeration in real time.
Description
technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to an anti-permeation type aerated biological filter. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the tank to meet the oxygen required by the aerobic microorganisms and the mixing conditions for full contact between the sewage and the activated sludge. The aeration tank is mainly composed of the tank body, The aeration system and the water inlet and outlet are composed of three parts. The pool body is generally made of reinforced concrete, and the plane shape is rectangular, square and circular. [0003] However, the biological aerated filter currently on the market is not only complex in structure, but also has a single function and low aeration efficiency. It is difficult to observe and understand the water distribution and aer...
