Background technology
Current sewage disposal technology basic forming, but the Eutrophication of the water body that nitrogen phosphorus excessive emissions causes, still that water pollutes the significant problem existed, sewage disposal no longer only be take and is removed organic matter (COD etc.) and be purpose, but should remove organic matter denitrogenation dephosphorizing again, reduce the water body Eutrophication, traditional Biological Nitrogen Removal Processe, comprise A/0, improvement A/0, the techniques such as oxidation ditch, though generally have Nitrogen/Phosphorus Removal, but reactor is many, complex process, energy consumption is high, in order to obtain simultaneously Nitrogen/Phosphorus Removal preferably, need to increase sludge reflux or additional carbon, not only increased the process operation expense, and produced a large amount of excess sludges.The denitrification nitrogen and phosphorus removal technology is existing certain development in recent years, it usings the electron acceptor of nitrate anion while replacing oxygen as dephosphorization, by Denitrifying Phosphate Accumulating Organisms, denitrogenation and dephosphorization process are united two into one, can overcome the contradiction between the traditional handicraft denitrogenation dephosphorizing, reduce aeration rate, the reduce mud discharge capacity, be the denitrification dephosphorization technique of energy-efficient and sustainable development, and this is focus and the inexorable trend of current municipal sewage denitrification dephosphorization technique research.About the denitrification nitrogen and phosphorus removal technology, a lot of research is also arranged now, although method can both obtain treatment effect preferably greatly at present, but in technique, ubiquity will carry out precipitate and separate to Denitrifying Phosphate Accumulating Organisms with a plurality of sedimentation basins, exist reactor many, many weak points such as step is many, and the reactor dischargeable capacity is little, and efficiency is low, be awkward.And present stage also lacks the device for biofiltration, therefore study a kind of biological membrane assembly that can filter more than 0.1um imperative.
The utility model content
The purpose of this utility model is to provide a kind of and filters plate film assembly for Sewage Biological Treatment, but other particle of 0.1um level, and purification filtering is respond well, simple in structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of for Sewage Biological Treatment filtration plate film assembly, comprise framework and be arranged on the plate film assembly in framework, plate film assembly comprises film body, film body has the bore passages that forms film body, and bore passages one end is communicated with by connecting flexible pipe the arm that catchments.The filter type of plate film assembly is: advance internal-suction type outward and filter.Namely from the outside of plate film assembly, enter the inside of plate film assembly, form and filter, adopt Smoking regime, take the clear water of plate film assembly inside away.Framework is for the support plate membrane module.
Plate film assembly is the earthenware slab membrane module.The earthenware slab membrane module is provided with the aperture of 0.1um, the catching probability and can reach more than 95% of its 0.1um particle.Use the PH scope to be 2-12, serviceability temperature can reach 80 degrees centigrade.
The arm that catchments is communicated with water header.Water after the water header exhaust filtering.
Bore passages is communicated with scavenge pipe and aeration tube away from an end that connects flexible pipe, between aeration tube and bore passages, is provided with loose gas blowout head.Scavenge pipe and aeration tube form back purge system, and one is dropped into gas, one and passes into flushing water.
The plate film assembly lower end is provided with the bottom water leg, and bore passages is communicated with the bottom water leg, and scavenge pipe is communicated with the bottom water leg, and aeration tube extends into the bottom water leg, and loose gas blowout head is communicated with the end that aeration tube extends into the bottom water leg.
The plate film assembly upper end is provided with the upper-part centralized tank, and water header is communicated with the upper-part centralized tank by connecting flexible pipe successively.
Framework is provided with the axis brace parallel with the plate film assembly surface.Brace increases the support degree of framework.
In sum, the utlity model has following advantage: but other particle of 0.1um level, and purification filtering is respond well, simple in structure.
