Embodiment Construction

[0021] like figure 1 , 2 As shown in and 3, a base 1 is provided at the bottom of an ultrafiltration membrane aeration plate, and after the top of the base 1 is grooved, the starting glue 2, the main glue 3 and the end glue 4 are filled on the left side, the center and the right side respectively, After laying the ultrafiltration membrane 5, solidify as a whole. The top of the main glue 3 is lower than the top of the base 1, submerging and sealing 75% of the circumference of the ultrafiltration membrane 5. The top of the starting glue 2 is flush with the top of the base 1 to fix the starting end of the ultrafiltration membrane 5 . The starting end of the ultrafiltration membrane 5 is opened to the air distribution chamber 6 in the rubber 2 at the beginning end, and the air distribution chamber 6 is connected to the gas supply device through the air inlet pipe 7 . The top of the end glue 4 is flush with the top of the base 1 to fix and seal the end of the ultrafiltration mem...

Abstract

The invention discloses an ultrafiltration membrane aeration plate and a method thereof. The bottom of the aeration plate is provided with a base seat, after the base seat is slotted, a starting end adhesive, a main body adhesive and a tail end adhesive are respectively filled in the left side, center and the right side of the base seat, and the ultrafiltration membrane is paved and solidified as a whole. The top end of the main body adhesive is lower than the top end of the base seat and the 75% of the circumference of the ultrafiltration membrane is flooded and sealed. The top end of the starting end adhesive is flushed with the top end of the base seat, and a starting end of the ultrafiltration membrane is fixed. The starting end of the ultrafiltration membrane is opened from an air distribution cavity inside the starting end adhesive, the air distribution cavity is connected with an air supply device by virtue of an air inlet pipe. The top end of the tail end adhesive is flushed with the top end of the base seat, and the tail end of the ultrafiltration membrane is fixed and sealed. Due to adoption of the ultrafiltration membrane aeration plate disclosed by the invention, air is cut into ultra-fine air bubbles of which the sizes are 10-100nm and is forced to be in contact with the liquid-phase main body and thus the air-liquid mass transfer efficiency and the effective utilization rate of the air are improved. The amount of the actual air supply of a biological treatment system is significantly reduced, meanwhile, the strong impact caused by high air velocity can be also avoided, the stability and operational flexibility of the system are improved and the ultrafiltration membrane aeration plate has good economic and environmental benefits.

Description

technical field [0001] The invention relates to an aeration device, in particular to an ultrafiltration membrane aeration plate and a method thereof. Background technique [0002] Aeration diffusion is one of the core technologies of the sewage biological treatment system, and its essence is to promote the mass transfer of oxygen from the gas phase to the liquid phase. The transfer of oxygen from the gas phase to the liquid phase requires the formation of a gas-liquid contact interface by means of fluid flow. The aerator is the key equipment to undertake the function of aeration and diffusion, and its function is to promote the mass transfer of oxygen. At present, the gas-phase fluid active movement type aerator is commonly used, which generates a three-dimensional continuous gas-liquid contact surface through the upward movement of the bubbles, and then completes the process of transferring oxygen from the gas phase to the liquid phase. [0003] According to the mass tran...
