Description
Technical field
The utility model relates to water-treatment technology field, is the filter tank of water treating equipment, and particularly a kind of upflowing biological filter is highly suitable for assorted draining, the recycling of sanitary sewage and the processing up to standard of industrial sewage.
Background technology
The biologic packing material that the filter tank is loaded in the prior art, filler hangs in the water during filtration, has bigger space to exist between the filler.These spaces have occupied the volume in a part of filter tank, make the space utilization efficient in filter tank reduce; In order to guarantee the water outlet effect in filter tank, adopt the method that prolongs hydraulic detention time usually, so also just increased the floor space in filter tank, increased filter tank investment construction cost.Require after the water outlet of filter tank, must flow through settling tank on the technology, increased floor space and cost of investment so virtually again.
The utility model content
The purpose of this utility model provides a kind of upflowing biological filter, in order to overcome the shortcoming in filter tank in the prior art.The utility model has adopted settling tank and filtering basin has been unified in technological method in the same structures, removed the settling tank that is provided with separately in the traditional technology, make equipment layout compactness, with low cost, reduced occupation area of equipment, made full use of limited space.
For achieving the above object, technical solution of the present utility model is: a kind of upflowing biological filter, comprise exhalant region, go up filter plate, filter material layer, water yield stable region, filter plate, water distributing area, gas distributing system, heavy dirty district, sewage draining exit down, effluent weir, side water leg, sewage inlet and structures;
Its filter tank is unified in settling tank and filtering basin in the same structures, in the cavity volume that structures surround, is divided into two portions with the effluent weir of vertical setting: the left side is precipitation and the filter tank of filtering combination, and the bottom surface, filter tank is taper, and the right side is the side water leg; Effluent weir is lower than the enclosure wall of structures.
Described upflowing biological filter, its described left side is precipitation and the filter tank of filtering combination, comprises filter plate, filter material layer, following filter plate, gas distributing system, sewage draining exit, sewage inlet, wherein, the upward filtration plate level places top, filter tank, and following filter plate level places the middle part, filter tank, and last filter plate top is an exhalant region, downside is the filter material layer of being close to, filter material layer is made of the lightweight biofilter material, and filtrate proportion is little than water, is water yield stable region between filter material layer below and the following filter plate; The enclosure wall of following filter plate below structures is provided with sewage inlet; Following filter plate below certain distance, the sewage inlet lower horizontal is provided with gas distributing system, is water distributing area between following filter plate and the gas distributing system, and the gas distributing system downside is to being heavy dirty the district between the tapered bottom of filter tank, and filter tank tapered bottom end side wall is provided with sewage draining exit.
Described upflowing biological filter, its described lightweight biofilter material, its specific gravity range is at 0.1～1.0g/m
3
The beneficial effects of the utility model are, light filter material is loaded in the filter tank, light filter material forms the density filter material layer during filtration, under the prerequisite that guarantees efficient removal water body BOD, COD, turbidity, eliminated the space between the filtrate, effectively utilize the space in filter tank, reduced the floor space in filter tank, saved construction cost.
Description of drawings
Fig. 1 is the composition structural representation of the utility model upflowing biological filter.
Embodiment
Embodiment of the present utility model:
As shown in Figure 1, filter tank in the utility model mainly comprises exhalant region 1, goes up filter plate 2, filter material layer 3, water yield stable region 4, filter plate 5, water distributing area 6, gas distributing system 7, heavy dirty district 8, sewage draining exit 9 down, effluent weir 10, side water leg 11, sewage inlet 12 and structures 13.
Filter tank in the utility model is unified in settling tank and filtering basin in the same structures, in the cavity volume that structures 13 surround, effluent weir 10 with vertical setting is divided into two portions: the left side is precipitation and the filter tank of filtering combination, and the bottom surface, filter tank is taper, and the right side is a side water leg 11.Effluent weir 10 is lower than the enclosure wall of structures 13, and structures 13 are the out of door treating pond.
The filter tank of the precipitation in left side and filtration combination comprises filter plate 2, filter material layer 3, following filter plate 5, gas distributing system 7, sewage draining exit 9, sewage inlet 12.Wherein, last filter plate 2 levels place top, filter tank, and following filter plate 5 levels place the middle part, filter tank, and last filter plate 2 tops are exhalant region 1, and downside is the filter material layer of being close to 3, and filter material layer 3 is made of the lightweight biofilter material, and filtrate proportion is little than water, and specific gravity range is at 0.1～1.0g/m
3Between filter material layer 3 belows and the following filter plate 5 is water yield stable region 4, and water yield stable region can reduce the turbulent fluctuation of current.The enclosure wall of following filter plate 5 below structures 13 is provided with sewage inlet 12.Following filter plate 5 below certain distances, sewage inlet 12 lower horizontal are provided with gas distributing system 7, are water distributing areas 6 between following filter plate 5 and the gas distributing system 7, and gas distributing system 7 downsides are to being heavy dirty district 8 between the tapered bottom of filter tank, and filter tank tapered bottom end side wall is provided with sewage draining exit 9.
During work, pending sewage enters water distributing area 6 through sewage inlet 12, current rising warp filter plate 5 down enters the uniform and stable current of water yield stable region 4 formation, macrobead suspended contamination in the water falls to the heavy dirty district 8 of bottom under the effect of deadweight, heavy dirty district 8 promptly is equivalent to the independent settling tank that is provided with in the traditional technology, the settling in heavy dirty district 8 can regularly be removed by sewage draining exit 9.
The current that arrived in the water yield stable region 4 continue upwards to flow, lightweight biofilter material in the filter material layer 3 is pushed, make the lightweight biofilter material form closely knit filter material layer 3, microbial film attached to filter material surface is a raw material with the organic substance in the water, under the competent situation of oxygen, (gas distributing system 7 constantly oxygenation in water in below is arranged), carry out aerobic reaction, the organic substance in the water is degraded to the small molecules inorganics, guarantee efficient removal water body BOD, COD, reduce turbidity.
Current after filter material layer 3 is handled continue upwards to flow, and to exhalant region 1, the effluent weir 10 that overflow then flows in the side water leg 11 on right side through last filter plate 2, and effluent quality is good, has reached national sewage emissions standard, last discharging naturally.
