Technical field
The present invention relates to a kind of beer bottle washing machine spent lye and purify the technology of recycling, exactly is a kind of multiple
Close ceramic membrane and reclaim beer wash bottle spent lye technical method.It adopts coagulation-ceramic membrane PROCESS FOR TREATMENT beer bottle washing machine spent lye, and alkali lye can be reused for the Beer Production wash bottle after treatment.
Background technology
Beer enterprise can produce the spent lye of a large amount of high temperature, high turbid, severe corrosive in to the process that reclaims the wash bottle of old bottle, traditional treatment method need add a large amount of acid solutions it is neutralized, to alleviate its impact to terminal sewage treatment facility.The method is not only moved the disposal cost height, and has wasted the NaOH that high economic worth is arranged in a large number.And series of advantages such as that composite ceramic film has is acidproof, alkaline-resisting, high temperature resistant, corrosion resistance is strong, mechanical strength is high, long service life, membrane flux are big; Be widely used in the sewage treatment industry now; The patent of invention that one Chinese patent application numbers 200910115118.8 discloses a kind of " active composite ceramic membrane purifier " is exactly a kind of sewage-treatment plant; Composite ceramic film is combined with coagulation technology; Develop the combined process system that is applicable to the spent lye wastewater treatment and can effectively regulate spent lye, advantages such as the processing accuracy that active composite ceramic membrane purifier has is high, area is big, retaining power is strong, life cycle is long, stable and reliable for performance, energy-conservation are given full play of.
Summary of the invention
The purpose of this invention is to provide a kind of composite ceramic film and reclaim beer wash bottle spent lye technical method; Spent lye water quality through bottle washing machine is discharged is relatively poor, and turbidity is more than 200NTU, and COD is greater than 2000mg/l; Alkali concn drops to below 0.8 %, and the exhaust outlet temperature is 55-75 ℃; Use composite ceramic film, controlling diaphragm pressure reduction 0.16-0.18MP, the cross-flow microfiltration mode is filtered spent lye; Delivery turbidity≤7.5NTU, COD≤300mg/l, alkali concn can remain on more than 6.5%; Can recycle the bottle washing machine spent lye effectively through the composite ceramics film device.Technical scheme is following: it comprises alkali lye water tank, alkaline-resisting centrifugal pump of horizontal axis, composite ceramics membrane module, inlet pipeline, return line, stillness of night delivery port, water tank drain, dope floss hole, P Pressure gauge, T thermometer, valve, it is characterized in that: adopt the wash bottle spent lye that produces in coagulation-composite ceramic film PROCESS FOR TREATMENT beer production.The alkali lye water tank connects water tank drain and alkaline-resisting centrifugal pump of horizontal axis through valve; Alkaline-resisting centrifugal pump of horizontal axis connects the composite ceramics membrane module through inlet pipeline; The composite ceramics membrane module connects alkali lye water tank and dope floss hole through return line; The composite ceramics membrane module is equipped with the clear liquid delivery port, controlling diaphragm pressure reduction 0.16-0.18MP, and the cross-flow microfiltration mode is filtered spent lye; Delivery turbidity≤7.5NTU, COD≤300mg/l.On composite ceramics membrane module inlet pipeline, return line and the clear liquid delivery port valve is installed all.Add PAC 80-150mg/L, PAM 0.5-2.5mg/L in the technology, mix 10-25min, can remove the COD of 60-80% in the spent lye and the turbidity of 80-95%.On composite ceramics membrane module inlet pipeline, return line and the clear liquid delivery port valve is installed all.When controlling composite ceramics membrane module mould difference under the 0.1-0.3MPa condition, ceramic film component is stable to the alkali lye treatment effect, and water yield is big.
Advantage of the present invention is:
1, the alkali lye turbidity≤7.5NTU that reclaims after this treatment system is handled, COD≤300mg/l, alkali concn>=6.5% satisfies the water quality index requirement of purposes such as beer producers wash bottle or desulfurization and dedusting.
2, this treatment system ceramic membrane scavenging period is short, and the membrane flux recovery rate is high; Through using the mode of acid wash liquid and oxidisability washing lotion combined cleaning, can accomplish cleaning in the 10-30min, the membrane flux recovery rate is more than 80%.
3, treatment effect is stable, and treating capacity is big; The apparatus structure integrated degree is high, and is simple to operate; The alkali lye recovery utilization rate is high, can create certain economic benefits.
4, the cycle of operation and cleaning frequency can carry out under not shutdown situation continuously, save time, and have improved treatment effeciency.
5, purify cost recovery and be lower than 25 yuan/ton, reclaim benefit near 40 yuan/ton; But the effective recycling resource is practiced thrift cost, increases economic efficiency.
