Problems solved by technology
However, this aeration plate is made by laying hollow fiber membranes flat, which is similar to the configuration of a curtain-type hollow fiber membrane module. In practical applications, this configuration may be limited by the configuration of the aeration membrane. The aeration plate cannot fill the entire container, resulting in uneven aeration

The invention discloses a hydrophobic membrane aeration device and belongs to the technical field of aeration devices. The hydrophobic membrane aeration device mainly comprises a membrane frame, a cross beam, a terminal pipe, a curtain type membrane assembly, an air distribution pipe and an air inlet pipe. The curtain type membrane assembly in the aeration device is of a bent structure in a space folding type, in other words, the curtain type membrane assembly in the aeration device is of an S-shaped structure, an air phase firstly enters the air inlet pipe and then enters the air distribution pipe and is dispersed in hydrophobic hollow fiber membrane filaments through the air distribution pipe, under operating pressure, the air phase is dispersed through membrane micro holes under pushing of differential pressure on the two sides and enters a liquid phase in a micro bubble mode, part of the air phase collides with water molecules in the liquid phase and is converted into a dissolution state, and the other part of the air phase overflows from the water without the time for collision.
Description
technical field [0001] The invention belongs to the technical field of aeration devices, in particular to a hydrophobic membrane aeration device. Background technique [0002] The aeration device is an essential device in the wastewater biological treatment process, especially in the activated sludge process, the aeration device is even more important. [0003] The currently widely used aeration devices are mainly divided into blast aeration, mechanical aeration and combined aeration. Among them, mechanical aeration equipment mainly includes surface aerators, rotary brush aerators, etc., which have the advantages of reliability, durability, and simple maintenance, but low efficiency and large power consumption; blast aeration equipment mainly includes perforated tubes, fixed aerators, etc. Microporous aerators, etc. Compared with mechanical aeration, blast aeration has high oxygenation efficiency and low power consumption, but it needs to empty the water in the structure d...
