Description
Technical field
The present invention relates to a kind of method and apparatus of processing whey wastewater, more particularly to be using multistage pre- place
The integrated technology of reason, biosystem and membranous system invents a kind of method and apparatus of processing whey wastewater.
Background technology
Whey is the byproduct produced in cheese, during producing cheese, after cow's milk condenses into bulk, and separation
It is whey to go out in the liquid of yellow green, transparence.And most lactalbumin all enters in whey in cow's milk, it is assumed that one
Its 1 ton of cheese of production, will discharge 9 tons of whey liqs, as discharge of wastewater, and the content of organic matter is opposite in whey wastewater
It is higher, total nitrogen, total phosphorus content also be significantly larger than discharge standard, if without appropriate processing, it will cause serious ring
It pollutes in border.The technical method of existing whey wastewater processing has water treatment by membrane technique, life assemblage treatment process and evaporated science and engineering
Skill.The shortcomings that Membrane Separation for Water Treatment is that the lactalbumin polysaccharide isocolloid of high concentration is easily attached to film surface, forms filter cake,
The decline of membrane flux is very fast, and cleaning is frequent, and system operation is unstable, and the frequent replacement of film consumptive material causes operating cost height；Bioanalysis
The shortcomings that be that cannot recycle useful albumen and polysaccharide resource, cause to waste；The shortcomings that evaporation is that energy consumption is higher, to recycling
Crystallization needs all or overwhelming majority evaporation, intermittent duty is unfavorable for system operatio.
Invention content
It is an object of the invention to overcome the shortcomings of above-mentioned prior art, provide a kind of for high concentration whey wastewater, place
Manage the method and apparatus for handling whey wastewater that effect is good, at low cost
A kind of concrete scheme of the method and apparatus of processing whey wastewater is as follows：
1. pretreatment stage：Whey wastewater introduces regulating reservoir under the action of intake pump, by whey raw water, collects waste water simultaneously
Balanced water distribution；The waste water in regulating reservoir is introduced into primary sedimentation tank later, flocculant is added, is removed in sewage by gravitational settling
Pollutant, SS, colloidal substance and TP are further removed finally by flotation tank.
2. biological treatment stage：Water outlet on last stage enters in circulatory pool, then lye is added to adjust this in pond
The pH value at place, later waste water enter in UASB, carry out anaerobic reaction, most of organic matter can be removed in whey wastewater；It is dirty
Water is discharged from the upper port of UASB, into the ponds A/MBR, is entered by bottom, mainly passes through nitrification and denitrification in this device
Reaction removal total nitrogen, COD.
3. the film process stage：By the water pumped in the above-mentioned ponds A/MBR, ultrafiltration and nanofiltration are passed sequentially through, film is passed through
Interception function further removes some SS, colloidal substance, macromolecule organic, the microorganism etc. in waste water, and finally water outlet reaches
To sewage drainage standard, COD, ammonia nitrogen numerical value can reach《Urban wastewater treatment firm pollutant emission standard》GB 18918-2002
Middle level-one emission standard A；
4. the Treatment of Sludge stage：Excess sludge in primary sedimentation tank, the ponds UASB and A/MBR is discharged into dirt by spoil disposal pipeline
In mud thickener, dosing flocculation further concentration, under the power effect of pump, it is de- that the sludge in sludge concentration tank enters sludge
Be dehydrated in water dispenser, in the body refuse and mud cake of generation contain a large amount of lactalbumin and polysaccharide material, finally by organic matter with
Dry mud form outward transport disposition, and the filtrate in sludge dewatering equipment is back in circulatory pool；
A kind of method and apparatus of processing whey wastewater, it is characterised in that：The regulating reservoir, primary sedimentation tank, air pressure pump, pressure
Dissolving, flotation tank, circulatory pool, the pond UASB, A/MBR, ultrafiltration apparatus and nanofiltration equipment are sequentially connected in series by pipeline.
The mud discharging mouth of the primary sedimentation tank bottom connects sludge concentration tank, and sludge concentration tank bottom water outlet connects sludge pump,
Under the action of sludge pump, sediment enters in sludge dewatering equipment, sludge dewatering equipment top delivery port and regulating reservoir water inlet phase
Even, filtrate is back to regulating reservoir from primary sedimentation tank top delivery port, and the solid matter generated is discharged by bottom mud discharging mouth.
However, other each unit bottoms are designed with mud discharging mouth, each mud discharging mouth is connected by sludge pipe, total mud discharging mouth
It is placed in above sludge concentration tank, the sludge that each unit generates enters sludge concentration tank by spoil disposal pipeline, in the work of sludge pump
It is dehydrated with the lower sludge dewatering equipment that enters, the upper end water outlet connection circulatory pool bottom water inlet of sludge dewatering equipment, and sludge passes through
The mud discharging mouth discharge of sludge dewatering equipment lower end.
The advantages and positive effects of the present invention are：
1. the present invention, using flocculation dosing and the dual preconditioning technique of air supporting, eliminates big portion in waste water in pretreatment stage
Divide SS, and the removal amount of COD, BOD, TN and TP are also relatively more, greatly reduce the load of subsequent biosystem.
2. the present invention is using the whey wastewater of UASB devices removal high concentration, degradable major part organic matter, removal efficiency
It is higher, while biogas can be generated in anaerobic processes, it can be used for generating electricity, realize that exhaust-gas resource utilizes.
3. the technique that the present invention is combined using UASB and A/MBR, substantially increases the removal efficiency of TN and TP in waste water,
The concentration of COD and BOD is relatively low in UASB water outlets, after entering the ponds A/MBR, since the concentration of BOD is not high, and the ponds MBR
Middle nitrobacteria is dominant bacteria, therefore is substantially carried out nitration reaction.
4. the present invention uses ultrafiltration and nanofiltration equipment, the water inlet of ultrafiltration and nanofiltration relatively to clarify, but still can be into one
Step goes particle, colloid, bacterium, microorganism and polymer organic matter remaining in water removal, clarification and effluent to make water outlet qualified discharge
Or reuse.
5. the present invention is recycled to sludge in the Treatment of Sludge stage, by the excess sludge that each unit generates by sludge pipe
Dewaterer can will contain organic matter containing organic substances such as a large amount of lactalbumin and polysaccharide in the body refuse and mud cake of generation
Sludge outward transport carries out further recycling.
