Problems solved by technology

[0006] In order to overcome the small specific surface area of ​​the traditional suspension carrier, insufficient biofilm coverage area, improper selection of materials and shape structure, long biofilm hanging cycle, easy to cause biofilm clogging, accumulation of anaerobic decomposition products, carrier sinking, affecting The defect of sewage treatment efficiency, the present invention provides a kind of biofilm suspending carrier, 1) improve carrier body structure, increase specific surface area; 2) carry out modification to carrier material, make biofilm thickness moderate; 3) biofilm carrier pass preferred microorganism Conduct training to shorten the film-hanging cycle of the trained biofilm carrier, which provides favorable conditions for the safe operation of the biochemical system and the achievement of high-quality effluent indicators

Embodiment Construction

[0015] The body of the biofilm suspension carrier of the present invention adopts a circular tube (1) structure, and a cross reinforcing rib (2) is arranged in the tube, and the reinforcing rib is connected with the inner wall of the circular tube to divide the tube into four equal parts of the inner cavity (4), and the inner and outer surfaces of the carrier The fine and irregular convex-convex undulating grains increase the adhesion of the biofilm, and the sufficient inner cavity space provides excellent conditions for the attachment and survival of microorganisms. A deflector (3) is set on the outer wall. When the biofilm suspension carrier is impacted by the aeration lifting force in the aeration tank, under the action of the deflector, it will float and move freely with the turning and turning of the water body in the aeration tank, increasing the biological The opportunity for the membrane to contact organic matter and absorb dissolved oxygen improves the biodegradability...

Abstract

The present invention relates to a biological membrane suspension carrier of biological membrane moving bed biochemical system applicable to sewage treatment engineering. It is made up by using composite material composed of high-molecular resin and inorganic active component. It adopts circular tube structure, and said structure is formed from the following components: cross-reinforcing rib, internal cavities, several flow deflectors and accilimatized membrane, etc.

Description

Technical field: [0001] The invention relates to a biofilm suspension carrier of a sewage biological treatment system in the technical field of environmental protection. technical background: [0002] The body of biological treatment in the biochemical system is sewage, and the pollution symptoms of water pollution can be physical, chemical or biological. Water bodies in nature generally have a certain self-purification ability. When the amount of pollutants discharged from the pollution source is small, the water body can gradually reduce the concentration of pollutants through self-purification, thereby returning to the original state. The self-purification of water mainly refers to the organic matter and part of the inorganic matter in the water body being decomposed by microorganisms into carbon dioxide, water, nitrogen, phosphorus and other inorganic matters under aerobic or anaerobic conditions, part of which is released into the air, and part of which is absorbed and ...
