Abstract

The invention discloses an aeration device for a rapid biochemical sewage treatment system, and relates to the technical field of sewage treatment. The aeration device for a rapid biochemical sewage treatment system comprises an air compressor, an air outlet of the air compressor is fixedly connected with the top end of an air guide pipe, a first annular pipe and a second annular pipe are arranged below the air guide pipe, the bottom end of the air guide pipe is fixedly connected with the top of the first annular pipe, an inner cavity of the air guide pipe is communicated with an inner cavity of the first annular pipe, and the axes of the first annular pipe and the second annular pipe coincide with each other. According to the aeration device for a rapid biochemical sewage treatment system, based on the arrangement of a turbulence forming mechanism, high-speed airflow can be intermittently sprayed out in the operation process of a movable air spraying mechanism, solid particles and sludge in sewage are further promoted to be away from the movable air spraying mechanism, and meanwhile, the sprayed high-speed airflow can be used as power to further enlarge the turbulence range of the water body, so that solid particles and sludge in the sewage tend to be uniformly distributed.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to an aeration device for a rapid biochemical treatment system for sewage. Background technique

[0002] At present, my country's urban sewage, domestic sewage, and municipal sewage treatment mainly include SBR process, A2 / O process, oxidation ditch process, and MBR process. These processes are relatively mature in the treatment of low-concentration and biochemical sewage treatment technologies, and they can all reach the first grade. B standard or above. With the increasingly stringent environmental protection requirements, such sewage is required to meet the first-class A standard after treatment. Therefore, it is imminent to upgrade or expand the capacity of new projects and old projects, but it is often limited by land occupation and is not easy to realize. Therefore, it is necessary to invent a new type of sewage rapid biochemical treatment facility and treatment metho...
