Problems solved by technology

However, most of the existing pulse aeration is controlled by electromagnetic valves. On the one hand, frequent switching of equipment may easily lead to actuator failure and pipeline pressure suppression. On the other hand, it also greatly increases the investment cost of equipment.

Abstract

The invention discloses an MBR pulse aeration device free of extra power and an aeration system with the same. The MBR pulse aeration device comprises an air supply mechanism, an MBR pulse aeration device body free of extra power, an aeration main pipe and a plurality of aeration branch pipes, wherein the MBR pulse aeration device body free of extra power comprises a shell and an air storage sink-and-float tank of which the density is greater than the density of water; a sliding chute for containing the air storage sink-and-float tank and enabling the air storage sink-and-float tank to sink and float in a reciprocating manner is formed inside the shell; a cavity is formed inside the air storage sink-and-float tank; the bottom end of the cavity is open; an air inlet pipe for supplying air to the cavity is arranged at the bottom of the shell; at least one air outlet pipe is arranged on the lateral wall of the top of the shell; a built-in valve and an air outlet corresponding to the air outlet pipe are arranged on the lateral wall of the top of the air storage sink-and-float tank; and the valve can communicate the cavity with the air outlet pipe when the air outlet of the air storage sink-and-float tank reaches the position corresponding to the air outlet pipe. The MBR pulse aeration device has the advantage that the air flow can be saved in comparison with constant-quantity and constant-speed aeration under the same purging effect, therefore, energy consumption is greatly reduced; and the device is simple in structure and good in purging effect, and manual intervention to control is avoided.

Description

technical field [0001] The invention is used in the technical field of sewage treatment, and in particular relates to an MBR pulse aeration device without additional power and an aeration system provided with the device. Background technique [0002] The treatment process of membrane bioreactor (Membrane Bioreactor-MBR) is an emerging water treatment technology, which is an organic combination of traditional sewage biological treatment process and membrane separation technology, and has been successfully applied to sewage treatment. Membrane bioreactors are generally composed of membrane separation components and bioreactors. Generally, membrane bioreactors place membrane components in bioreactors to achieve high COD removal rates by isolating high-concentration activated sludge. . [0003] The focus of the design of the membrane bioreactor is a high-efficiency membrane cleaning system, and the optional methods include water backwashing, air washing, and chemical cleaning. ...
