Problems solved by technology

[0003] In the reaction tank in the aerobic zone, it is necessary to continuously feed air into the interior to increase the oxygen content in the reaction tank for the use of nitrifying bacteria. It is easy to aggregate during the floating process, and the large volume of air bubbles is difficult to mix well with the sewage

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.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an aerobic zone reaction pool in sewage treatment. Background technique [0002] In the aerobic zone, the phosphorus accumulating bacteria decompose the PHA stored in the body under the condition of aeration and oxygenation and release energy, which is used for bacterial growth and active overabsorption of dissolved phosphorus in the surrounding environment. Phosphorus bacteria exist in the form of polyphosphate salts, which greatly reduces the concentration of phosphorus in sewage. After experiencing anaerobic and anoxic environments, the concentrations of various organic substances in sewage are already quite low when they enter the aerobic zone, which will be conducive to the growth and reproduction of autotrophic nitrifying bacteria. Nitrifying bacteria will complete ammonia in an aerobic environment Nitrification and nitrification, converting nitrogen in water to N...
