Description

Technical Field

[0001] This utility model relates to the technical field of pulse-type MBR aeration devices, and in particular to a pulse-type MBR aeration device. Background Technology

[0002] MBR (Membrane Bioreactor) technology introduces membrane separation technology into wastewater biological treatment systems. It is a biochemical reaction system that organically combines membrane separation technology with sludge biological treatment, representing a novel wastewater treatment process. By using hollow fiber membranes or MBR membranes to replace traditional secondary sedimentation tanks, it achieves highly efficient solid-liquid separation, resulting in good and stable effluent quality with near-zero bacteria, suspended solids, and turbidity.

[0003] Chinese Patent CN217127067U discloses an adjustable pulse aeration device for MBR membrane modules, which produces high burst aeration intensity, stronger bubbles, adjustable aeration pulse time, and high compressed air utilization efficiency. The pulse aeration device includes an aeration box housing and multiple float switches connected within the housing. The inner cavity of the housing is an aeration chamber, with an air inlet on one side for connecting to an air source. Below the aeration chamber are multiple open-bottomed float compartments corresponding to the float switches. Each float switch includes a float, a float guide rod, a seal, and a limiting nut. This allows for a more thorough cleaning of the fiber membrane module surface. Furthermore, the pulse aeration device requires no additional auxiliary systems; the pulse time and aeration intensity can be adjusted by regulating the float weight, resulting in significant energy savings.

[0004] When using existing MBR aeration devices, the air generated by aeration is discharged from the aeration pipe at high intensity through the aeration port. The aeration intensity can be adjusted by replacing the floating parts. However, dirt can easily enter the aeration port and the opening of the floating chamber, causing dirt to enter the structure of the aeration device. This makes it difficult to block the dirt, resulting in increased cleaning frequency and reducing the practicality of the pulse MBR aeration device. Utility Model Content
