Description
Technical field
The invention belongs to the packing technique fields that environmental protection industry (epi) sewage treatment uses, and in particular to a kind of moving-bed biofilm
Suspending carrier filler.
Background technique
State in which is different in water according to microorganism for organic sewage bioremediation, can be divided into activated sludge process and
Biofilm.Wherein biofilm water treatment facilities can be roughly divided into three classes according to the filler motion state added in system: Gu
Fixed bed, expanded bed and fluidized bed.
Fluidized bed is that a certain number of suspending carriers are added into reactor, improves biomass and biological species in reactor
Class, to improve the treatment effeciency of reactor.It is micro- with water in being thoroughly mixed state when aeration since packing density is close to water
The environment of biological growth is gas, liquid, solid three-phase.The collision and shear action of carrier in water, keep air bubble more tiny, increase
The utilization rate of oxygen is added.Fluidized bed is to locate the carrier filler in reaction unit always using gas-liquid or mechanical stirring as power
In a kind of sewage water treatment method of motion state, since carrier to be made sufficiently fluidizes, dead angle is not stayed, therefore to provide sufficiently large
Power, the power that this causes this method to consume compared with contact oxidation method are big；In addition because collided between sluicing, carrier fierceness etc. because
Element be easy to cause biofilm detachment, and biomass reduces, and effluent quality is poor, influences treatment effect.
Commonly fluidizing bed fillers mainly in sewage treatment at present has honeycomb padding, soft-filler, semi soft packing, stands
Body filler, porous rotation ball-type floating stuffing, Ball-type packing, column filler etc., but in Practical Project operational process, if existing
Dry problem.
Pillar shap suspension filler, structure are cylindricality lateral branch support body frame, have inwardly been evenly distributed centripetal item on rib, on
Lower both ends are respectively disposed with guide plate.This filler shape, structure is complicated, and manufacture difficulty is big, and specific surface area is also not big enough.
Sponge filler is soft-filler, and quality is lighter, is easily floated on the water surface, it is difficult to be fluidized.And sponge filler demoulding is tired
Difficulty, needing to squeeze releases sludge.Sponge filler is easily lost, and timing is needed to supplement.
Traditional wastewater processing floating stuffing mostly uses fiber hydrophobic material, to meet filler fluidisation shape requirement, aerating system
Aeration quantity it is bigger than simple activity sludge, this be for the attachment of microorganism it is very unfavorable, biomass is difficult to maintain
As soon as higher level, this makes the raising of sewage treatment degree become a bottleneck.
Summary of the invention
The purpose of the present invention is to provide a kind of sewage treatment moving-bed biofilm suspending carrier filler, the filling-material structures
Large specific surface area, to bubble facilitate transmit and spread effect, the effect of water process can be effectively improved.
Its technical solution includes:
A kind of sewage treatment moving-bed biofilm suspending carrier filler comprising shell and the cavity positioned at the shell
Interior obturator, the obturator are to be wrapped in the cavity of shell to be formed by several HDPE, and the moving bed is raw
The shape of object film suspending carrier filler is cylindrical, spherical or rectangular；The moving-bed biofilm suspending carrier filler it is close
Degree is 0.93~0.97g/cm3。
As a preferred solution of the present invention, described several HDPE are wrapped in shell in honeycombed.
As another preferred embodiment of the invention, shape is cylindrical filler with a thickness of 10~100mm, outer diameter model
It encloses for 10~100mm.
Further, it is 10~100mm that shape, which is the diameter of spherical filler,.
Further, it is 10~100mm that shape, which is the side length of rectangular filler,.
Above-mentioned sewage treatment moving-bed biofilm suspending carrier filler is prepared using the molding mode of integral molded plastic
Gained.
Sewage treatment of the present invention moving-bed biofilm suspending carrier filler, appearance are high density polyethylene (HDPE) Natural color,
Density is 0.93~0.97g/cm3, lower energy consumption can be utilized, realizes active fluidization；By several filiforms HDPE inside it
Winding bonding, generally cylindrical, spherical or square structure, in water can 360 degrees omnidirection move freely, no dead zone；This
The space network of invention filler can be realized the porosity of filler, and more microorganism growing multiplications can be provided for filler
Space is conducive to microorganism apposition growth in netting, biofilm can be realized within about 2~5 days；Filler of the present invention has good compression and back
Bullet rate, compression rebound rate are up to 95%~99%, can spring back rapidly after being squeezed, therefore will not deform, is damaged, use the longevity
Life length；Filler of the present invention has biggish porosity, is 85~95%, permeability is fine, and aqueous vapor liquid can be good by filling out
Among each gap of material and microorganism；Filler of the present invention is easy to fluidize, aeration intensity about 1.5~8Nm3/m2H, stirring intensity
About 5~20W/m3 pool capacity.
Compared with prior art, present invention offers following advantageous effects:
1) space network can be realized the porosity of filler, and more microorganism growing multiplications can be provided for filler
Space is conducive to microorganism apposition growth in netting, than the time that the biofilm time of conventional fillers shortens 30%~50%；
2) filler external diametrical extent is 10~100mm in the present invention, and outer diameter can be adjusted according to practical situations, to adjust
The effective ratio area for saving the biologic packing material enables its comprehensive performance greatly to be promoted；
3) for hard fillers such as Ball-type packing, cylindrical hollow fillers, compression rebound rate is low, is squeezed rear cracky etc.
Disadvantage improves.Involved filler has good compression rebound rate in this patent, and compression rebound rate is up to 95%~99%,
It can be sprung back rapidly after being squeezed, will not deform, is damaged, can reduced to the abrasion between pond body and equipment, extend whole system
Service life；
4) the most material of the conventional fillers such as Ball-type packing, cylindrical hollow filler is polypropylene material, density 0.90g/cm3
Left and right, easily floats on the water surface, is unfavorable for filler fluidisation.Involved filler is improved in this patent, and material is pure HDPE material
Material, density are 0.93~0.97g/cm3, density is 1.002~1.01 after biofilm, it is close with water, it is in water in suspended state, because
This can utilize lower energy consumption, realize active fluidization；
5) the disadvantages of difficult, easily loss need to supplement to sponge filler demoulding, has carried out improvement, it can be achieved that in normal cycle
Demoulding, without supplement.
