The solid support material type selecting is bad.Now many sewage disposal devices adopt plastics, and the materials such as terylene are made carrier, be easy to balling after its for some time of working and greatly reduce surface-area in sewage, thereby affect sewage treatment capacity.
Support density is difficult to control.When carrier was very few, the microbial film that adheres to generation was not enough, caused sewage treatment capacity not enough.When carrier was too much, the microbial film that adheres to generation was blocked up, easily caused local the obstruction and affected sewage treatment capacity.
Below be the carrier picture of certain sewage works use after 1 year.A large amount of carriers also have more diaphragm to get lodged in the circulation pump housing due to the excessive obstruction that comes off of load, have a strong impact on the normal operation of wastewater treatment facility.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and is easy to microbial film and adheres to, and surface-area is large, the biological treatment carrier of the Dyeing ﹠ Finishing Industry waste water of favorable working performance.
Technical solution of the present utility model is:
A kind of biological treatment carrier of Dyeing ﹠ Finishing Industry waste water is characterized in that: comprise polyamide fibre and/or polypropylene fabric, fabric is by warp and weft interweaving part and only form by the part of warp thread is spaced apart.
Filament number through weft yarn is 〉=500dtex, and the length of relaxed state a slice fabric is 28.0 ± 0.5cm, and the length of tensioning state a slice fabric is 30.0 ± 0.5cm, is 15.0 ± 0.5 rhizoid/inches through density, and weft density is 18.0 ± 0.5 rhizoid/inches.
Described fabric has multi-disc, and multi-disc fabric interval is fixed on the stainless steel frame that immerses treatment tank.
The utility model is easy to microbial film and adheres to, and surface-area is large, and flow resistance is little, and intensity is large, and chemistry and biologically stable are good; The appropriate design support density can improve the microbial film supporting capacity of carrier, can guarantee again to form between carrier the flow velocity of homogeneous, makes and brings about the desired sensation, and water, microbial film are able to fully contact exchange, guarantees that good biological treatment is active.
1) the sewage purification mechanism of carrier
When sewage passes through treatment tank, carrier is held back the suspended matter in sewage, and the colloidalmaterial in sewage is adsorbed on the surface of oneself, organism in them is bred microorganism very soon, these microorganisms have further been adsorbed again the material that is dissolved state in sewage, and carrier surface has formed one deck microbial film gradually.Microbial film mainly is comprised of the zoogloea of bacterium and a large amount of fungal filaments, wherein also has many protozoons and grows than higher animal.Microbial film not only has very large surface-area, can adsorb in a large number the organism in sewage, and has the ability of very strong degradation of organic substances.When enough oxygen was arranged, microbial film just can decompose the organism that oxidation is adsorbed.
2) utilize carrier to remove organic process
Sewage passes through carrier surface with certain flow velocity, effect due to microorganism, slowly form water membrane at carrier surface, namely adhere to water layer, all the other waste water pass through its surface with lamelliform, form the water layer that flows, and directly contact with microorganism because adhere to water layer, organism wherein is mostly by Institute of Micro-biology's oxidation, so organic concentration is very low.And the water layer that flows namely enters the pending waste water of biological filter, and organic concentration is higher.Organism is transferred in attached water by diffusion from flowing water and is gone, oxygen also passes through flowing water simultaneously, attached water enters in biomembranous aerobic layer, and a large amount of aerobic microorganisms that growing in microbial film have formed the food chain of organic pollutant-〉 bacterium-〉 protozoon (metazoan).Metabolic activity by bacterium, organism is degraded, make and adhere to water layer and be purified, the inorganics such as meta-bolites such as water and carbonic acid gas drains in flow water layer and air in opposite direction, and under the effect of mass transfer, organic pollutant in mobile water layer passes to and adheres to water layer, thereby the water layer that flows progressively is purified in the process that flows.
1) selection of carrier and manufacturing
Now many sewage disposal devices adopt plastic film, and the materials such as polyster fibre bundle are made carrier, are easy to balling after its for some time of working in sewage, and the centre is anaerobic state, and greatly reduces surface-area, thereby affects wastewater treatment efficiency.
The utility model adopts polyamide fibre in man-made fiber, polypropylene fibre as the basic raw material of carrier.By woven mode, it is combined into netted, and make warp and weft interweaving part not have the weft yarn part spaced apart with only having warp thread merely, make carrier can obtain the high specific surface-area in biological treatment process, can carry out good metabolism again.The biochemical treatment ability that thoroughly solves thus sewage in time passing and more and more weak problem.
