Abstract
The utility model provides floating type composite biological stuffing for voids, belongs to the filed of sewage and feed water treatment, and is suitable for various bioreactors. The floating type composite biological stuffing for the voids comprises a hard mesh-shaped casing and at least a plurality of medium blocks of the same kind for being filled into the casing, and is characterized in that the overall proportion of the biological stuffing ranges from 0.8g/cm2 to 1.0 g/cm2. The floating type composite biological stuffing for the voids has the advantages of being rich in microbial population and synchronous in nitration-denitrification, reducing sludge amount, resolving the problem of sludge blocking and being capable of being used in the various bioreactors which are anaerobic, anoxic or aerobic and the like. The bioreactors using the biological stuffing can achieve long-term stable running, simultaneously improve biochemical efficiency, and greatly reduce discharge amount of sludge.
Description
Technical field
The utility model belongs to environmental protection technical field, and particularly water-treatment technology field relates to a kind of floatation type composite gap biological filler, is applicable to flotation bed anaerobic biological reactor, flotation bed anoxic bio-reactor and thermopnore aerobe reactor.
Technical background
Along with Economic development, human more and more serious to the pollution of water, thereby to water purification, WWT and regeneration effluent require increasingly high.Putting before this, it is most important that novel sewage disposal technology and method also more and more seem.
There are problems such as active sludge is prone to run off, sludge activity is low in the anaerobism of traditional sewage water treatment method, anoxic and aerobe reactor.The biologic packing material technology can be fixed on filling surface with mikrobe, and the realization current separate with living microorganism on the spot, are most important methods that improves bio-reactor efficient.Yet brought between filler the space easily by sludge blockage when improving the efficient of bio-reactor, influence the technical problem such as even mobile of water and gas with biologic packing material.
Sludge of sewage treatment plant is handled has become thorny problem of environmental pollution gradually.Lowering the sludge of sewage treatment plant quantity discharged is the new problem that sewage disposal technology faces.In fact the overwhelming majority of WWT discharging mud is made up of mikrobe, mikrobe corpse or mikrobe corpse fragment.The overwhelming majority of these compositions can be by biochemical degradation.Yet WWT mud contains various bacteria, bacterium corpse or bacterium corpse fragment, and these mud of degrading need complicated biochemical system.
The known technology composite gap biological filler can be realized separating of current and living microorganism with hard reticulattion (ball) parcel rubble (Chinese patent ZL 00218362.5); Also can partly reduce the WWT sludge discharge; But because rubble lacks micropore; Should not form anaerobic environment, influence the efficient and the mud decrement effect of this kind filler.
Micropore composite gap biological filler (Chinese patent 200920350411.8,03277701.9) comprises modification sponge, coke briquette, medium charcoal piece, charcoal lump, activated carbon block, volcano sillar or perforating ceramic block etc. with the netted shell parcel of hard microporous medium piece; Increased the inner micropore of medium block; And the environment in the micropore has the anaerobism characteristic more; Thereby making microbial population further abundant, the effect of synchronous nitration-denitrification and mud decrement is better.
Yet composite gap biological filler or micropore composite gap biological filler are bed technology, and biologic packing material is sunken to the bottom of bio-reactor with mud, and in the course of time, mud stops up the space of biologic packing material, influences the working efficiency of biologic packing material.
Summary of the invention
The utility model will solve composite gap biological filler or the micropore composite gap biological filler uses the technical problem in sludge blockage space, back for a long time.
In order to achieve the above object; The utility model floatation type composite gap biological filler comprises a netted shell of hard and is filled at least a a plurality of medium blocks in the said shell; The whole proportion that it is characterized in that biologic packing material is between 0.8-1.0; This kind biologic packing material major part is immersed in the processed water during use, swims in the water simultaneously.
Said medium block comprises block expanded plastic, sea piece, activated carbon block, coke briquette, medium charcoal piece, charcoal lump, volcano sillar, zeolite piece, ceramic block, haydite, iron ore, Rock Phosphate (72Min BPL), stone.
The packing fraction of this biologic packing material in all kinds of bio-reactors is 20-90%, and it is low excessively to be lower than 20% o'clock efficient, surpasses at 90% o'clock and lacks the fluid-space.
When using the utility model floatation type composite gap biological filler with aerobic mode; Biologic packing material is realized flowing under gas water lift stream drives; Water and biologic packing material more effectively are in contact with one another, can constantly the microbial film of accumulative mud or disengaging in the filler be dashed from filler through G&W stream again.
When using the utility model floatation type composite gap biological filler with anoxic or anaerobism mode, biologic packing material swims in the top of reactor drum, and mud then is sunken to the bottom of reactor drum, makes excess sludge be able to discharging.In case of necessity can interim ground in reactor drum aeration with the excess sludge in the stripping filler.
Description of drawings
Fig. 1 is the floating composite gap biological filler structural representation of the utility model.
The netted shell of 1. hard, 2. medium block among the figure
Embodiment
Referring to Fig. 1; The utility model floatation type composite gap biological filler comprises a netted shell of hard (1) and is filled at least a a plurality of medium blocks (2) in the netted shell of said hard (1) that the whole proportion that it is characterized in that said floatation type composite gap biological filler is between 0.8-1.0g/cm
2Between.This proportion is higher than 1.0g/cm
2The time, filler will be sunken to the bio-reactor bottom, can not realize floating function, be lower than 0.8g/cm
2The time buoyancy part filler is emerged, make these fillers that emerge to play a role.
The netted shell of said hard (1) is processed by metal or plastics, and geometrical shape is spherical, and diameter is between the 30-250 millimeter.The netted shell of this hard (1) can make during less than 30 millimeters the space between the netted shell of hard (1) be prone to by sludge blockage; The netted shell of this hard (1) can reduce pack density during greater than 250 millimeters and influence flowing of medium block (2) surrounding fluid.
The mesh size of the netted shell of said hard (1) is the 5-60 millimeter.The mesh of the netted shell of said hard (1) can influence fluid flow less than 5 millimeters, and the mesh of the netted shell of said hard (1) can not be greater than the diameter of medium block (2).
The netted shell of said hard (1) is made up of two portions at least, behind filling medium piece (2), can or compile the seam mode with screw thread, flange, buckle two portions are combined.
The diameter of said microporous medium piece (2) is the 10-60 millimeter.The space of the diameter of microporous medium piece (2) microporous medium interblock during less than 10 millimeters is prone to by sludge blockage, the diameter of microporous medium piece (2) during greater than 60 millimeters microporous medium piece specific surface reduce the efficient that will influence bio-reactor.
Said medium block (2) is one or more combinations in expanded plastic, sea piece, activated carbon block, coke briquette, medium charcoal piece, charcoal lump, volcano sillar, zeolite piece, ceramic block, haydite, iron ore, Rock Phosphate (72Min BPL), the stone.
The packing fraction of institute's hole medium block (2) in the netted shell of hard (1) is 30-80%.This packing fraction be lower than 30% will influence bio-reactor efficient., packing fraction is unfavorable for that the microporous medium piece floats with the mud around the wash-out microporous medium piece where necessary when being higher than 80%.
