Abstract

The invention discloses a novel BAF gas-liquid jet mixed aeration device which comprises a gas-liquid jet device, a gas-liquid distribution header pipe, a gas-liquid pressure difference balance pipe,a gas-liquid injection pipe and an injection diffusion cover, a liquid inlet of the gas-liquid ejector is connected with a sewage pipe, a gas inlet is connected with an air blower, and a gas-liquid outlet is connected with a gas-liquid distribution header pipe, two ends of the gas-liquid distribution main pipe are connected with the gas-liquid pressure difference balance pipe to form a loop structure, a plurality of groups of gas-liquid injection pipes are connected between the gas-liquid distribution main pipe and the gas-liquid pressure difference balance pipe, a plurality of groups of gas-liquid injection holes are formed in the two sides of the gas-liquid injection pipe, and meanwhile, an injection diffusion cover is mounted on the periphery of the gas-liquid injection pipe in a stacking and sleeving manner. According to the invention, dual functions of high-efficiency gas-liquid jet mixing and aeration are realized, and the problems of blockage, non-uniformity, low oxygenation efficiency, difficulty in maintenance and the like existing in a biological aerated filter for a long time are effectively solved.

Description

technical field [0001] The invention relates to the technical field of oxygenation and aeration for sewage treatment / sewage advanced treatment, in particular to a novel BAF gas-liquid jet mixed aeration device. Background technique [0002] Biological aerated filter (BAF) is a biofilm water treatment process that appeared in Europe in the late 1970s. The biological aerated filter was originally used for the advanced treatment after the secondary treatment of sewage, and it is an economical and applicable sewage regeneration and purification technology. As we all know, the conventional BAF aeration tank aeration method micropores are prone to clogging, short flow, uneven aeration, and difficult maintenance. The aeration and oxygenation efficiency of the perforated tube is low. Oxygenation and uniformity. Therefore, the problem of low oxygenation efficiency makes it difficult for the operation effect of the biological aerated filter to meet the design requirements, which res...
