Problems solved by technology

As a process that combines the activated sludge method of suspended growth and the biofilm method of attached growth, the current MBBR reactor has the advantages of both, but there are also problems that the filler is easy to lose and the filler is easy to accumulate at the water outlet, resulting in filler distribution. Uneven etc.

Abstract

The invention discloses a moving bed bio-film reactor which comprises a main reactor body, wherein the main reactor body is internally filled with filler; an aerator pipe is arranged around the bottom of the main reactor body; the aerator pipe is provided with an aerator head; the side wall of the main reactor body is provided with a water inlet and a water outlet; the water inlet and the water outlet are arranged above the aerator pipe; the main reactor body is internally and additionally provided with a water outlet screen; and the screen is connected with the water outlet by a water pipe. The moving bed bio-film reactor is simple in structure and scientific in design; and by using the moving bed bio-film reactor, the problems that the filler is unevenly distributed and is easy to run off are well solved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a moving bed biofilm reactor. Background technique [0002] The moving bed biofilm reactor (MBBR) is directly fed into the aeration tank with suspended fillers with a specific gravity close to water as the active carrier of microorganisms. Attached to the carrier, the floating carrier moves freely in the reactor with the turning and turning of the mixed liquid, so as to achieve the purpose of sewage treatment. As a process that combines the activated sludge method of suspended growth and the biofilm method of attached growth, the current MBBR reactor has the advantages of both, but there are also problems that the filler is easy to lose and the filler is easy to accumulate at the water outlet, resulting in filler distribution. unevenness etc. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a mo...
