Description
Technical field
The present invention relates to a kind of bio-disc, its manufacture method, and the bio-disc reactor of composition.
Background technology
In biological sewage treatment equipment, just bring into use bio-disc in eighties of last century five sixties, bio-disc is a kind of biomembrance process wastewater processing technology, bio-disc can grow survival time longer microorganism, sludge age is long, have longer anti impulsion load ability, treatment effect is good.In technique and maintenance operation, bio-disc has the advantages such as microorganism concn is high, mud does not need backflow, power consumption is low, working cost is low.The bio-disc now usual industry used normally is made up of resin, glass reinforced plastic, stainless steel, non-woven fabrics etc.And Apilanez have studied six kinds of disc material such as glass particle, diatomite, sand, stainless steel, polyvinyl chloride and gac to the impact of biofilm development in experimental study, found that, when 4-6r/min and 40% submergence than, the most favourable biomembranous formation of the gac that surfaceness is the highest and growth.This is the excellent results that the characteristic of the structure and its high-specific surface area forming the loose porous of high roughness due to activated carbon surface produces to a great extent.
But although the bio-disc of gac possesses very large specific surface area, also there is very large space microbial film its inside.Can contriver find in trial-manufacturing process, microorganism in the microbial film of its inside is due to the obstruct of outer activated carbon structure and biological film body, usually be in treatment sewage nutrient concentrations not enough, in the environment that metabolic waste cannot be got rid of, this has had a strong impact on the performance of the bio-disc sewage treatment capacity of gac.
Summary of the invention
Goal of the invention: the object of the invention is to the bio-disc that can improve gac bio-disc actual sewage processing power.
Technical scheme: bio-disc of the present invention, is characterized in that, comprises disk body, described disk body is gac disk body, described disk body is provided with some fluid exchange holes, ingress, described fluid exchange hole is provided with drainage cone, and described fluid exchange bore end is closed.This fluid exchange hole, by punching on carbon fiber disk body, has manufactured the outer passage of linking up between treatment sewage and the microbial film of disk body inside of a disk body.Described drainage cone is for being arranged on the conical indentation in disc surfaces, and effluent stream can be converged by this pyramidal structure after arriving this drainage cone, guides to fluid exchange hole, and infiltrates from the gap of the inner gac of exchange hole, then oozes out from the gap of disc surfaces.Nutritive substance in sewage is brought into the microbial film place of bio-disc inside, and take the metabolic waste of Internal biological film generation out of.
Reinforcing fiber is provided with in described gac disk body.Contriver finds when manufacturing experimently the gac system biology disk body with aforesaid liquid exchange hole, and due to the structure that gac is loose porous, intensity is very limited.It often there will be at drill process, and disk body is cracked causes the problem that good article rate is extremely low; therefore reinforcing fiber is added in the material manufacturing gac disk body; such as glass fibre or carbon fiber, effectively can improve the good article rate of this kind of gac disk body in actual production.
Fluid exchange hole of the present invention is laid on the side at disk body edge, and points to disk body center, and is partial to the reverse direction of the sense of rotation of disk body.The rotary action that this kind of plan of establishment can effectively utilize disk body itself guides more liquid to flow to into fluid exchange hole.
The present invention also comprises the bio-disc reactor being provided with above-mentioned arbitrary described bio-disc, it is characterized in that, comprises described bio-disc.
Further, comprise reactor cavity, electric motor, the first transmission shaft, coaxial reduction gear, second driving shaft, described motor rotary shaft is connected to described first transmission shaft, the described first transmission shaft the other end is connected to described coaxial reduction gear, described coaxial reduction gear is connected to second driving shaft again, the other end of described second driving shaft is connected to the inwall place of described reactor cavity, and described first transmission shaft and second driving shaft are respectively arranged with some bio-disc.Setting like this, because the first transmission shaft place is closer to sewage fluid inlet, concentration of wastewater is high, thus bio-disc rotating speed is faster needed to improve processing efficiency, and second driving shaft place concentration of wastewater is low, in order to reach best processing efficiency, needing to reduce bio-disc rotating speed, therefore adopting the scheme of being connected by coaxial reduction gear between the two to make to reach optimum revolution at these two sections simultaneously.Avoid repeating to arrange multiple electric motor simplified construction, also achieve both interlock adjustment, simplify controlling organization.
