Description
Technical field
The present invention relates to sewage treatment area, particularly relate to a kind of biofilter.
Background technology
BAF is the biofilter of new generation grown up in Europe before 10 years.In filter tank, ground Biomass is up to 10～15g/L, considerably increases volumetric loading, saves sedimentation tank, has the advantages such as occupation of land little, energy consumption is low, efficiency is high, stable and reliable operation.
BAF is that a kind of high load capacity submerged fixes film phase reactor, has fully used the filtering technique in Water purification, and the cycle being realized filter tank by backwash regeneration is substituted.First use successfully in France at beginning of the eighties late 1970s, obtained on Europe, America, Japan and other places subsequently promoting and drunk.The main feature formula of biological aerated filter uses bulk material that particle diameter is less as filtrate, and filtrate is submerged in water, utilizes blast aeration oxygen supply.Filter material layer acts on of both playing, and one is as microorganism carrier, and compared with general biofilter, owing to it has bigger specific surface area, sewage is long with time of contact of biomembrane reality, and biochemical reaction can be made to carry out more thorough；Two can serve as filter medium, retain into the suspended solid in water and the biosolids being newly formed, obtain the water outlet of high-quality.
Many floras of different nature can be grown in biological aerated filter.In the filtering layer nearer away from water inlet end, the organic concentration in sewage is higher, and various heterotrophism are preponderated, and mainly removes BOD；In the filtrate that distance outlet is nearer is heavy, the organic concentration in sewage is the lowest, and the nitrifier of autotrophic type will be preponderated, and can carry out the nitration reaction of ammonia nitrogen.Nitrifier is present in biomembranous inner side, filtrate has the strongest adhesive ability, once formed, be difficult to completely fall off, by being adjusted flexibly of oxygenation intensity along filter height, make cooperating of anoxic zone, bottom and aerobic zone, upper strata, biological aerated filter has the highest nitrification and removes the ability of ammonia nitrogen, air water relative motion, and gas liquid interfacial area is big, gas and water, factory's biomembranous time of contact, thus improve utilization rate and the treatment effect of oxygen.
The filter tank of prior art generally comprises water and air distributing district and the treatment region of bottom, but treatment region is typically only single filler, carry out single aerobic reaction, treatment effeciency has much room for improvement, such as: China Patent No. is a kind of BAF type integrated sewage treating apparatus of 201420260072.5, disclose and include filter tank, inlet and outlet system, gas distribution system and rinse-system, packing layer supporting plate it is provided with in described filter tank, multiple filter or porous water distributor it is provided with on described packing layer supporting plate, described filter tank is divided into the water distributing area below being positioned at and treatment region above by described packing layer supporting plate, cobble supporting layer and haydite filtering layer it is disposed with from low to high in described treatment region, be positioned at described treatment region in described filter tank is arranged above exhalant region；Described gas distribution system includes that aeration tube, described aeration tube are arranged in described cobble supporting layer；Described inlet and outlet system includes sewage water inlet pipe and processes water outlet pipe, and described sewage water inlet pipe communicates with described water distributing area, and described process water outlet pipe communicates with described exhalant region；Described rinse-system includes recoil air inlet pipe and backflushing water intake pipe, and the described outlet side of recoil air inlet pipe and the water side of backflushing water intake pipe are arranged in described water distributing area.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, improve a kind for the treatment of effeciency high, simple in construction, floor space is little, it is achieved the materialization life assemblage filter tank that materialization is strong with biochemical multiple reaction and depth degradation ability.
For realizing the object of the invention, provide techniques below scheme: a kind of materialization life assemblage filter tank, including housing, housing is separated into water and air distributing district the most successively, treatment region, described treatment region separates by arranging supporting plate with water and air distributing district, it is characterized in that described treatment region is divided into materialization district from the bottom to top, anoxic zone, the overflow exhalant region on aerobic zone and top, aeration tube aeration it is provided with in materialization district and anoxic zone, hole membranes aeration it is provided with in aerobic zone, described materialization district is filled with spheroidal cast irons filler, anoxic zone is filled with anoxia magnetic bio haydite material, aerobic zone is filled with aerobic magnetic bio haydite material, it is provided with swash plate in overflow exhalant region, top, swash plate overflow area is provided with overflow effluent trough.Realize the ceramic grain filter in ascending current during backwash is separated from water by swash plate.
As preferably, in water and air distributing district to lower and on be provided with water inlet pipe, backwash trachea, backwash water pipe and aerator.
Beneficial effects of the present invention: the present invention is efficiently, compact conformation, floor space are little and depth degradation ability strong, substantially increase sewage treating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
