Integrated aerobic fluidized bed circulation reaction wastewater treatment device

Abstract

The invention relates to the technical field of wastewater treatment devices, in particular to an integrated aerobic fluidized bed circular reaction wastewater treatment device. the device comprises an aerobic fluidized bed; a water inlet pipe is arranged on the outer wall of the aerobic fluidized bed; the end part of the water inlet pipe is connected with a connecting pipe; the connecting pipe isfixed on the outer wall of a separation cylinder; a driving shaft is rotatably connected into the separation cylinder; a grid scraper is arranged on the surface of the driving shaft; an enclosure frame is arranged between the separation cylinder and the aerobic fluidized bed; and a water leakage screen plate is arranged on the bottom surface of the enclosure frame. The integrated aerobic fluidized bed circular reaction wastewater treatment device has the beneficial effects that the water inlet end is connected with the separation cylinder, and the driving shaft in the separation cylinder drives the grid scraper to rotate to scrape and convey impurities in wastewater and throw the impurities into the enclosure frame, so that the situation that the wastewater treatment effect is affected due to the fact that too hard and too large impurities enter the aerobic fluidized bed is avoided.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment devices, in particular to an integrated aerobic fluidized bed circulating reaction wastewater treatment device. Background technique [0002] The diversion cylinder type fluidized bed, or internal circulating fluidized bed, is a relatively popular fluidized bed technology at present. It is equipped with a diversion cylinder in the traditional three-phase fluidized bed, which improves the mixing of the reaction medium in the reactor. In recent years, there have been many studies on this kind of fluidized bed. The power source of the traditional three-phase fluidized state is completely dependent on the aeration system, which is relatively simple. There are no strict boundary conditions for the certainty and stability of the internal circulation flow state, which is not conducive to the realization of high mass transfer capacity of the fluidized bed. The traditional three-phase aerobic...

Problems solved by technology

[0003] In the prior art, during the use of the integrated aerobic fluidized bed, the wastewater injected into it will be mixed with too hard and too large impurities, which will damage the internal activated sludge, and the heavy impurities will affect the suspension of internal substances. , so that its effect on wastewater treatment is reduced
