Abstract
The utility model discloses a biological fluidized bed suspension carrier, which consists of a hollow cylindrical shell (1) and at least three clapboards (2) which are arranged inside the hollow cylindrical shell (1), wherein teeth (3) are uniformly distributed on the outer surface of the hollow cylindrical shell (1); the cross section of the hollow cylindrical shell (1) is circular or elliptic; an angle of between 60 and 120 DEG is formed between two adjacent clapboards (2) in the hollow cylindrical shell (1); the inside of the hollow cylindrical shell (1) is divided into 3 to 6 through holes; and the tooth profile angles alpha of the teeth (3) are 5 to 25 DEG. The utility model has the advantages that: the suspension carrier has large specific surface area, readily-available raw materials and low cost and improves water treatment efficiency; and the specific gravity of carriers attached with microorganisms is approximate to that of water, so that energy consumption is greatly reduced.
Description
Technical field
The utility model relates to a kind of microbe carrier, particularly a kind of biological fluidized bed suspending carrier.
Background technology
Along with China's economic construction dynamics continues to increase, sanitary sewage, industrial sewage and urban comprehensive wastewater amount are also in rapid increase, biological sewage treatment occupies an important position in sewage disposal, biological sewage treatment comprises activated sludge process and biomembrance process etc., wherein, the core that the saprobia film is handled is exactly biomembranous carrier, microorganic adhesion is in the bio-carrier surface, the pollutent that utilizes himself metabolism to absorb in the water is purified waste water, so the performance of bio-carrier directly affects the metabolic whole process of microorganism, therefore also directly affect sewage treatment effect.
At present, both at home and abroad the bio-carrier that adopts mainly contains: pottery, gac, hard coal, fine quartz sand, yellow sand, flue dust, slag, baton round etc., problem such as their ubiquity pump around circuit energy consumptions are big, specific surface area is little, processing efficiency is low.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the biological fluidized bed suspending carrier that a kind of pump around circuit energy consumption is little, specific surface area is big, processing efficiency is high is provided.
The purpose of this utility model is achieved through the following technical solutions: the biological fluidized bed suspending carrier, it is made of hollow cylindrical housing and three dividing plates that are located at the hollow cylindrical enclosure interior at least, and the hollow cylindrical housing outer surface is evenly distributed with teeth.
Described hollow cylindrical housing cross section is circular or oval, and the angle of hollow cylindrical enclosure interior two adjacent dividing plates is 60 ° ~ 120 °, and the hollow cylindrical enclosure interior is divided into three ~ six through holes.
The tooth profile angle α of described teeth is 5 ° ~ 25 °.
The utlity model has following advantage: carrier inside is provided with dividing plate, and outside surface is provided with teeth, can attached microbial on the surface of hollow cylindrical shell inner surface, baffle surface and teeth, improved the specific surface area of microbe carrier greatly; Surfaces of carrier materials has micropore to exist, and has improved the sticking power of biological bacteria greatly, has improved biomembranous thickness, thereby has effectively improved the ability and the effect of treatment unit; Carrier proportion is slightly less than water-mass density, and behind the carrier surface attached microbial, the carrier proportion of attached microbial increases, and near the density that maybe can reach water, the carrier of attached microbial is in suspended state naturally, can significantly reduce the pump around circuit power consumption; Material is easy to get, and cost is low, and corrosion-resistant long service life.
