Description
Technical field
The present invention relates to a kind of moving-bed bioreactor for treating dyeing waste water, belong to the manufacturing technology field of treatment of dyeing wastewater equipment for reclaiming.
Background technology
Dyeing is the rich and influential family in the industrial water drainage industry, and the waste water quantity of being discharged is big, organic pollutant content height, colourity is dark, alkalescence is big, biodegradability is relatively poor, belongs to one of unmanageable trade effluent.In recent years, development along with new chemical fiber, emulation silk, printing and dyeing finishing technique, refractory organics such as polyvinyl alcohol New-type adjuvant enter in the waste water in a large number, have increased difficulty to wastewater treatment, and the removal efficient of original biological treatment system is obviously reduced.Because the These characteristics of dyeing waste water not only makes wastewater treatment difficulty up to standard increase, processing cost increases, and has influence on the reuse of waste water.People have done many explorations at the dyeing waste-water reuse technology in recent years, and existing treatment technology related to the present invention mainly contains:
1, dyeing waste-water → coagulating sedimentation → internal circulating anaerobic → HCR/ biologic active carbon filtration absorption → catalytic oxidation → fibre-ball filtration → reuse.This scheme is that the HCR method is combined with the biological activated carbon method, and the less and fibrous nodules of floor space has the advantages that filtration velocity is fast, effect is excellent, makes that waste water is stable to reach the reuse requirement.But this technology is compared with traditional printing dye water technology, still has the higher shortcoming of cost of investment and running cost, and can cause the accumulation of salinity after the long-time running and have influence on quality product.
2, dyeing waste water → add acid for adjusting pH value → iron carbon to filter → add alkali neutralization → intermittent activated sludge process (SBR) → reuse.It is the waste iron filing of iron and carbon that iron carbon filtering system adopts main component, can be used as filler after pre-treatment and activation, and this technological advantage is the treatment of wastes with processes of wastes against one another, and is stable, and weak point is that the pH value must be regulated mensuration back and forth.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, compact overall structure, treatment effect is good, the moving-bed bioreactor for treating dyeing waste water of save energy.
The present invention is a moving-bed bioreactor for treating dyeing waste water, it is characterized in that comprising the moving-bed body, places the packing layer of moving-bed body inner bottom part band micro-hole aerator, places the water-in and the porous effluent weir case of both sides, moving-bed body top.
Filler in the described packing layer can be length 50～150mm, the cylindrical plastic particle of diameter of section 3～10mm.
The distribution density of filler can be packing layer 1 volumetrical 60～90% in the described packing layer.
Described micro-hole aerator can link to each other with the pneumatic pump blower fan of peripheral hardware by aeration tube.
Also can be provided with the control of dissolved oxygen determination mouth and water level in the described packing layer and measure mouth.
Also can be coated with the interception net on the described packing layer, to stop the excessive of filler.
The bottom of described moving-bed body also can be provided with mud discharging mouth, is used for emergent or maintenance.
The present invention compared with prior art has following outstanding advantage and positively effect:
1, reasonable in design, low and the moderate characteristics of B/C value at light polluted waste liquid COD concentration, by in packing layer, rationally selecting the cylindrical plastic granular filler for use, make it to become biomembranous support and carrier, and according to what, requirement such as processing efficiency height of biomass in the difficulty or ease of biofilm, the moving-bed body, through repetition test relatively, cylindrical plastic coating of particles size and distribution density have rationally been determined, make microorganism a large amount of breeding and adhering on filler, kind is many, biological food chain length, the processing efficiency height.By micro-hole aerator oxygen is poured equably to packing layer simultaneously, make filler produce shearing, obstruct and adsorption, the residence time of bubble and gas-liquid contact area are increased, improved mass-transfer efficiency, saved the energy bubble.In addition, filler the washing away of flowing water stream of being bullied, the aged film can constantly come off, and makes carrier outside surface microbial film thinner, guarantees biomembranous activity, is beneficial to biological metabolism.
2, compact overall structure is removed efficient height, organic loading height, and treatment effect is stable, no sludge bulking; Save the area, be applicable to treatment system newly-built and reconstruction, the filler specific area is big, and loss of pressure head is little; The filler stable material quality, long service life directly adds, and need not fix, and free movement does not have the dead angle in the aeration tank, mass transfer is good; Treatment effect is fairly obvious, saves energy consumption, has directly actively benefit.
3, with the present invention and automatically dividing technology, decolouring oxidation, operation is supporting is used in combination in efficient purification etc.Optionally dyeing waste water is carried out advanced treatment and reuse, treatment effect is good, and water quality after treatment can reach the reuse water quality requirement, satisfies enterprise's production requirement, and the mud that purification is produced is after plate-and-frame filter press is handled, and dewatered sludge fully utilizes.Through actual motion chemical oxygen demand CODcr≤100mg/L, turbidity≤5 degree, colourity≤15 times, PH:7-7.5.Reuse water after the processing is used for each operation such as pre-treatment dyeing rinsing, and energy-saving and emission-reduction reduce water withdrawal, and the conserve water resource is protected national resource.
