Construction and analysis of microporous aerator

Structure and Analysis of Microporous Aerator The structure of microporous aerator is required. The diaphragm type microporous aerator requires diaphragm punching, small pore size, small bubbles, many pores and more oxygenation efficiency. Too many holes result in a shortened life of the diaphragm. Therefore, the processing of the diaphragm requires double optimization of oxygenation and membrane life, and it cannot be neglected.

Secondly, the anti-floating requirements of the aerator are caused by the lack of anchoring force of the aerator. The Tianjin Jizhuangzi Wastewater Treatment Plant was the first to introduce British aeration equipment. It used the special tools to measure the tensile force of each anchor point according to the requirements of foreign drawings. The tubular membrane aerator has a two-layer structure, and the compressed air is in the interlayer, and the sewage can enter the central pipeline to weaken the buoyancy and ensure the stability of the aerator.

There is also the discharge of condensate from the aerator, which is also an important problem in operation. If the aeration hole of the aerator can be set at the bottom, it can be both aerated and drained, which is one of the advantages of the tube aerator. .

Finally, for the SBR process, the aerated sedimentation of the biochemical pool is completed in the same pool, and the activated sludge must be deposited on the surface of the aerator. For the disc aerator, it is relatively easy to block, but The bottom aeration hole of the tube aerator is not easy to block. Therefore, it is reasonable to use a tube aerator for the current SBR (including CASS process, CAST process, ICEAS process, etc.) process.
