Description
Technical field
This utility model relates to a kind of vortex fixed microorganism aeration tank bio-carrier, belongs to field of mechanical technique.
Background technology
Biological contact oxidation process is a kind of biomembrane process between activated sludge process and bio-aeration pool, it is characterized in dosing carrier in pond, sewage is carried out oxygenation by aeration at the bottom of pond, and make sewage in cell body be in flow regime, to ensure that sewage is fully contacted with the carrier in sewage, it is to avoid biological contact oxidation pond exists sewage and contacts the defect of inequality with carrier.
At present, being widely used that spiral-flow type spherical suspending filling material, it is a netted ball, is placed in waste water in suspended state.Because can be interactive with waste water, the biologic packing material comparing some relative quiescent has better effect.But, spherical frame and the interaction of built-in granular filler are then substantially not enough, and adhesion sheeting, not easily demoulding when forming granular filler biomembrane are deposited at the bottom of pond because biofilm is overweight time serious.Owing to spiral-flow type spherical suspending filling material is passive floating with aeration current, also can because of the drive of current or lifting sink-float, but because being overly dependent upon the effect of current, or the waters of relative quiescent more weak at current can be assembled in heaps, thus reducing its due effect, reduce the ability of biofilm demoulding, have impact on the effect of sewage disposal.
Utility model content
This utility model provides a kind of vortex fixed microorganism aeration tank bio-carrier, solves the deficiency of existing bio-carrier technology, it is proposed to a kind of porous microbial carrier.
For solving above technical problem, this utility model provides following technical scheme: a kind of vortex fixed microorganism aeration tank bio-carrier, cylindrical stereochemical structure；Including bio-carrier body, carrier walls and cylindrical structure, described bio-carrier body is hollow structure, and inwall is arranged on the carrier walls that bio-carrier body central place intersects to form, and bio-carrier body is divided into multiple inside to be the space of turbofan shape by carrier walls；Arranging the cylindrical structure with bio-carrier body equal height in the center that carrier walls is intersected, make carrier walls one end be connected to bio-carrier inner body wall, the other end is connected to cylindrical structure outer wall.
Further, described bio-carrier body is the cylindrical tube structure that the periphery of extrusion molding is corrugated.
Further, the material of described bio-carrier body is polyethylene, polystyrene or polypropylene.
Further, described cylindrical structure cross section inwall radius R=4mm 8mm, height H=12mm 18mm, cylindrical structure wall thickness is 0.3 0.5mm.
Further, the total of described bio-carrier is disposable extruded forms, and material is polyethylene, polystyrene or polypropylene.
This vortex fixed microorganism aeration tank bio-carrier that this utility model relates to, this utility model material is plastics, including polyethylene, polystyrene and polypropylene etc., makes full use of the feature that plastic shaping is good, it is squeezed into the internal turbofan shape carrier of cylindrical outer corrugated, nontoxic, tasteless.
Radius of circle R=4mm 8mm, length H=12mm 18mm bottom this bio-carrier, outer wall thickness 0.3 0.5mm, light weight, it is possible to utilize aeration current to act on displacement and roll up and down in vortex fixed microorganism aeration tank, abundant and water haptoreaction.Flowing sink-float ability in water and the spatial configuration of the porous of carrier own, improve the area that carrier is fully contacted with the microorganism such as oxygen, mushroom, thus improve sewage treatment capacity.
In addition, its voidage reaches more than 82%, and bulk density is typically in 500 ~ 800kg/m3Between simple in construction, light weight intensity is high, and back washing strength is little, and energy consumption is low, and hydrophilicity is good, and antiseptic property is good.

Detailed description of the invention
As Figure 1-Figure 2, a kind of vortex fixed microorganism aeration tank bio-carrier, for stereochemical structure；Including bio-carrier body 1, carrier walls 2 and cylindrical structure 3, described bio-carrier body 1 is hollow structure, being arranged on the carrier walls that bio-carrier body central place intersects to form on inwall, bio-carrier body is divided into multiple inside to be the space of turbofan shape by carrier walls；Arranging the cylindrical structure with bio-carrier body 1 equal height in the center that carrier walls is intersected, make carrier walls 2 one end be connected to bio-carrier inner body wall, the other end is connected to cylindrical structure 3 outer wall；The total of described bio-carrier is disposable extruded forms, and material is polyethylene, polystyrene or polypropylene.This bio-carrier structure is a kind of symmetrical structure, current has enforceable turbulent fluctuation effect, enables waste water to be uniformly distributed.The setting of its loose structure, plays certain filtering function to float.
Bio-carrier body 1 is the cylindrical tube structure that the periphery of extrusion molding is corrugated；The material of described bio-carrier body 1 is plastics, it is possible to for polyethylene, polystyrene or polypropylene, to form light structures.
Described cylindrical structure 3 cross section inwall radius R=4mm 8mm, height H=12mm 18mm, cylindrical structure wall thickness is 0.3 0.5mm.
This vortex fixed microorganism aeration tank bio-carrier that this utility model relates to, cellular space structure provides provides the stable environment perched, grow and breed, easy to be filmed for microorganism.Outer surface can perch aerobic microbiological, and micro-cylindrical structure can form anaerobic environment, is suitable for the existence of amphimicrobe and anaerobe, therefore can be suitable for multiple types, multifarious microorganism coexists, and can keep more microbial biomass.
Institute of Micro-biology is aerobic to be supplied by blast aeration, biofilm development is to certain thickness, the microbes of carrier walls carries out anaerobic metabolism because of anoxia, the souring that the gas produced and aeration are formed can cause biomembranous coming off, and promoting the growth of neoplasm film, the biomembrane come off flows out outside pond with water outlet.Biomembrane tolerates impact load to a certain extent；Old and feeble microbial film is prone to come off, and can more effectively utilize the dissolved oxygen in waste water and target degradation product.
In vortex fixed microorganism aeration tank, owing to bio-carrier spatially structure, surface area are relatively big, so each stage of biofilm development is simultaneous, the ability of organics removal is stable.Bio-aeration pool is intake the eddy current formed so that sewage and biologic packing material mixing are more abundant, and biomembrane is attached on Aeration tank filler and absorbs the pollutant decomposed in sewage, be effectively improved the treatment effect of vortex fixed microorganism aeration tank.
Bio-carrier is the place of biomembrane and waste water in vortex fixed microorganism aeration tank, and current can be had enforceable turbulent fluctuation effect by this bio-carrier, enable waste water to be uniformly distributed；Can also as the medium removing float, its strainability affects again the BAF removal effect to float.
Detailed description of the invention described in the utility model is not intended that the restriction to the application scope; within every spirit in this utility model design and principle, any amendment that one of skill in the art can make, equivalent replacement and improvement etc. should be included within protection domain of the present utility model.
