Abstract
The invention discloses an aerobic zone reaction tank in sewage treatment. The aerobic zone reaction tank in sewage treatment comprises a reaction tank, wherein a conveying pipe is arranged on the bottom part of the reaction tank; multiple output ends communicate onto the conveying pipe; a grid plate and a movable plate are arranged in the reaction tank; the grid plate is arranged above the movable plate; two ends of the grid plate are fixedly connected with the inner wall of the reaction tank; multiple springs are connected between the grid plate and the movable plate; multiple limiting shafts are fixedly connected below the grid plate and penetrate through the movable plate; suspension boxes are symmetrically arranged under the movable plate; and balance weight liquid is filled in the suspension boxes. According to the aerobic zone reaction tank in sewage treatment provided by the invention, a floating force in the air ascending process input into the reaction tank is utilized for pushing the movable plate, the movable plate moves to the grid plate, and large-volume bubbles stayed in the movable plate is extruded in the movement process and are then extruded into small bubbles, so that a bubble crushing effect is achieved, and the contact area of the bubbles and nitrifying bacteria in sewage is increased.
