The light biological filtering material of the utility model has the advantages of large specific surface area, good filtration performance, high mechanical strength, long service life, large permissible pollutant capacity, easy backwashing, good backwashing effect, backwashing without external force and low water consumption, etc., and is very suitable for separating and removing organic compounds and suspended impurities in water.
Description
Technical field
The utility model relates to water-treatment technology field, and particularly a kind of lightweight biofilter material is highly suitable for separating organism and the suspended impurity of removing in the water.
Background technology
The biologic packing material that the filter tank is loaded in the prior art, filtrate 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, and the filter tank effluent quality does not reach optimization.Because filler hangs in the water, have each other at interval, so in backwash process, do not exist reactive forces such as collision, friction between filler, this has just increased the difficulty of filler backwash, make filler backwash effect not reach predetermined requirement, shortened the work-ing life of filler, increased the expense of equipment operation.
The utility model content
The purpose of this utility model is at the weak point of filler in the prior art in water treatment procedure, discloses a kind of lightweight biofilter material, and its proportion is little than water, and the treatment effect of increasing water quality is efficient and convenient to the anti-cleaning of filtrate.
For achieving the above object, technical solution of the present utility model is:
A kind of lightweight biofilter material, its profile are spheroidal or elliposoidal or open column shape, and proportion is at 0.1～1.0g/m
3Between;
During for spheroidal or elliposoidal, its surface smoothing or band microspike or regular striped, particle diameter is between 0.5～20mm;
During for open column shape, length is 2～30mm, and end face circle external diameter is 2～20mm, and internal diameter is 1～18mm.
Described lightweight biofilter material, its material comprise modified polystyrene, polypropylene, poly macromolecular material or hydrophobic composites.
Described lightweight biofilter material, its surface hangs with microbial film.
Lightweight biofilter material beneficial effect of the present utility model is, compare with the filtrate of available technology adopting, effectively utilized the space in filter tank, saved the filter tank construction cost, improved water treatment effect, and can utilize water to carry out the gravity back flushing from the body exhalant region, realized cleaning efficiently and easily to filtrate, improve backwash efficiency, reduced the backwash water loss, shortened the backwash time.

Fig. 2 is the synoptic diagram of the utility model filtrate when being in the filtration state;
Fig. 3 is the synoptic diagram of the utility model filtrate when being in the backwash state.
Embodiment
As shown in Figure 1, be a kind of lightweight biofilter material of the utility model, wherein, Fig. 1 a is a spheroidal, and the surface has the lightweight biofilter material particle of equally distributed microspike; Fig. 1 b is a spheroidal, the lightweight biofilter material particle of surface smoothing; Fig. 1 c is a spheroidal, and the surface has the lightweight biofilter material particle of longitude and latitude shape regular streaks; Fig. 1 d is an elliposoidal, the lightweight biofilter material particle of surface smoothing; Fig. 1 e is an elliposoidal, and the surface has the lightweight biofilter material particle of longitude and latitude shape regular streaks.During for spheroidal and ellipsoidal particle, particle diameter is 0.5～20mm.
Fig. 1 f is an open column shape, the lightweight biofilter material particle that its surfaces externally and internally is all level and smooth, and its length is 2～30mm, and end face circle external diameter is 2～25mm, and internal diameter is 1～18mm.
Lightweight biofilter material of the present utility model, proportion is at 0.1～1.0g/m
3Between.
Lightweight biofilter material of the present utility model adopts macromolecular material such as modified polypropene, polyphenyl alkene, polystyrene or hydrophobic composites to make.Because the proportion of filtrate is little than water, so under the state of nature, filtrate is in levitated state in water.In filtration procedure, filtrate forms the density filter material layer under the co-extruded of ascending current and upper strata baffle plate, and the space between the filtrate reduces greatly, has effectively utilized the space in filter tank, has saved the filter tank construction cost.This particle diameter of filter medium is less, the surface-area of filtrate is bigger, and filtrate can fully be contacted with water body, and the microbial film that filter material surface forms is removed organism and the suspended impurity in the water effectively, greatly reduce the index such as BOD, COD, turbidity of water body, improved water treatment effect.The filtrate utilization is carried out the gravity back flushing from the water of body exhalant region, has realized the cleaning to filtrate efficiently and easily.During backwash, under the acting in conjunction of the microbubble of the generation of the water outlet on filter material layer top and gas distributing system, carry out the gravity back flushing.Exist reactive forces such as mutual collision, friction between the filtrate, make the dirt that adheres to filter material surface obtain effective removal, improved backwash efficiency, reduced the backwash water loss, shortened the backwash time.
As shown in Figure 2, when the utility model filtrate is in the filtration state, ascending current enters into water yield zone of transition 4 by following filter plate 5, form density filter material layer 3 with last filter plate 2 co-extruded filtrates, through filter material layer 3 and pressurized air acting in conjunction, handle through a series of biopurifications, clear water flows out from exhalant region 1.
As shown in Figure 3, when the utility model filtrate was in the backwash state, backwash water was flowed downward by exhalant region 1, and the bubble that produces with gas distributing system 7 dispels filtrate, realizes the air-water backwashing of filtrate.
