Abstract
New bio disc reactor described in the utility model, comprise reactor cavity, bio-disc, 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.
Description
Technical field
The present invention relates to a kind of new bio disc reactor, belong to the technical field of sewage disposal device.
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.
Further, due to bio-disc reactor front and rear part should concentration of wastewater different, different rotating speeds should be adopted to have reached optimum handling effect.And contriver finds, the current of isocon can be flushed on bio-disc, are unfavorable for the biomembranous attachment of bio-disc.
Summary of the invention
Goal of the invention: the object of the invention is to the new bio disc reactor that can improve gac bio-disc actual sewage processing power.
