Abstract

The invention relates to a device for sewage treatment based on an MBBR (moving bed biofilm reactor) process. The device is composed of a first-stage treatment unit, a second-stage treatment unit and a deep treatment unit; the first-stage treatment unit is composed of an anaerobic tank and an anoxic tank; the second-stage treatment unit is composed of two groups of inner circulation aeration tanks and sedimentation tanks, and adopts the MBBR process; and the deep treatment unit is composed of a medicine adding tank, a reaction tank and a water-collecting well. Sewage is successively subjected to first-stage treatment, second-stage treatment and deep treatment, thus the quality of discharged water is guaranteed to reach a standard. The device for the sewage treatment based on the MBBR process has the advantages of compact structure and high impact load resistance, can guarantee the discharged water quality, and is suitable for waste water treatment in small and middle-sized hospitals, life places, breeding places and the like.

Description

Technical field [0001] The invention relates to sewage treatment equipment of MBBR technology, which belongs to the field of water treatment. Background technique [0002] Water is the material basis for the survival of human beings and all living things. In the absence of water resources, water pollution has become a major constraint on social and economic development. In many parts of China, various complex factors have caused many water bodies to be seriously polluted, further exacerbating the scarcity of water resources. [0003] The moving bed biofilm reactor (MBBR) is a kind of suspended filler with a specific gravity close to water that is directly added to the aeration tank as an active carrier of microorganisms. The filler is in a flowing state by the aeration in the aeration tank and the lifting effect of the water flow. So as to achieve the process of sewage treatment. As a process that combines the activated sludge method of suspended growth and the biofilm me...
