Description
Technical field
The present invention relates to the special equipment that a kind of pyridoxol prepares the wastewater produced processing method of pyridoxal.
Background technology
Pyridoxal (pyridoxal, PL) is one of constituent of vitamin B6.It is to aoxidize the aldehyde obtained by pyridoxol.
It is unstable in neutral and alkalescence, photodissociation easily occurs.Have an impact to streptococcus lactis (Streptococcuslactis) growth, its
Effect is big compared with alcohol of trembling thousands of times, this as the material for recovering the de- antelope enzyme effect of tyrosine, is extraction of the nineteen forty-two from internal organs
It is found in thing.Effect in vivo is to form phosphopyridoxal pyridoxal phosphate.Coenzyme effect with many enzymes.Therefore not only its
Itself is widely studied and used in medicine, field of biology, and relative product is also carried out in-depth study.
Manganese dioxide is used as depolarizer of dry cells, the catalyst and oxidant of compound probability, glass industry and porcelain enamel industry
Colouring agent, depigmenting agent, deferrization agent etc..For manufacturing manganese metal, special alloy, ferromanganese casting, breathing mask and electronic material
Ferrite etc..In addition, it may also be used for rubber industry is to increase the viscosity of rubber.Catalyst can be also used as in chemical experiment.
Most common pyridoxal preparation method is to use manganese dioxide pyridoxol.The associated products such as pyridoxal it is corresponding
Preparation method also go through the research and exploration of many researchers.But have no that someone specializes in its wastewater treatment at present
Method, especially have no the processing method of succinct efficient, low cost oxidation section waste water.Contain soluble divalence in this kind of sewage
Manganese salt, about concentration are 0.3 ~ 0.4mol/L, and COD is about 20000, and color is deeper.
The many related researchs existing at present of electrolysis processing sewage, its principle is all the transfer gain and loss of electronics, so that
Organic matter decomposition, mineralising are obtained, reaches and lowers COD, the purpose of ammonia nitrogen.Electrolysis is divided into direct current electrolysis and light electrolysis（It is also referred to as interior
Electrolysis）, the current density of DC electrolysis can be adjusted has bigger applicability with respect to light electrolysis, and the meaning of the words is not
Say that DC electrolysis can solve all problems, because this method cost is very high.Light electrolysis cost is more relatively low, but pays attention to it
The problem of filler is hardened, while the sludge brought is also relatively more, sludge belongs to dangerous solid waste, subsequently there is secondary pollution.In a word all
It is problematic.Currently without the electrolysis tech specialized in for handling pyridoxal sewage.
The research of biochemical process sewage treatment has had upper century-old history, and biochemical process cost is low, and effect is good, but has
Limitation, it can not many times meet to require, such as high salt or bio-toxicity waste water.The intensity of the sewage of biochemical process processing simultaneously
Also than relatively low, COD is too high, and often bacterium is not suitable with, and biochemical process does not just apply to.
The content of the invention
It is an object of the invention to provide a kind of good pyridoxol of effect to prepare the wastewater produced processing method of pyridoxal
And special equipment.
The present invention technical solution be：
A kind of pyridoxol prepares the wastewater produced processing method of pyridoxal, it is characterized in that：The waste water is that pyridoxol prepares pyrrole
Tremble waste water caused by oxidation step during aldehyde；Using the soluble manganese salt in oxidizing sewage, insoluble two are prepared
Manganese oxide solid, manganese dioxide solid is recovered by filtration；Reclaimed the sewage after manganese dioxide further across electrolysis improve B/C,
Activated carbon decolorizing, biochemical treatment.
Described oxidant is one kind or several in hydrogen peroxide, Peracetic acid, ozone, potassium permanganate, potassium hyperchlorate, electricity
Kind.
Oxidizer is 2 ~ 15 times of COD amounts in sewage.
A kind of pyridoxol prepares the special equipment of the wastewater produced processing method of pyridoxal, it is characterized in that：Including
Oxidation reaction and filter plant, oxidation reaction is carried out to sewage, and manganese dioxide solid is recovered by filtration；Oxidation reaction and filtering are set
Standby rear setting electrolysis unit, is electrolysed to the sewage after oxidation reaction and filtering, improves B/C values；Set successively after electrolysis unit
Put activated carbon decolorization device, biochemical treatment apparatus.
The positive plate that the electrolysis unit uses is platinum titanium alloy, titanium iridium ruthenium alloy, lead one or more combination therein；
Biochemical treatment apparatus adds Aerobic Pond form using anaerobic tower.
Described electrolysis unit carries the square wave power that can adjust current strength as needed, when meeting different inflows
Processing requirement.
The draw ratio of described anaerobic tower is not less than 7:1;Using epoxy resin, PEEK coatings, polytetrafluoro inside anaerobic tower
Ethene, gather inclined tetrafluoroethene, PE, PET, PPS or enamel anticorrosion.
The sewage to after oxidation reaction and filtering is electrolysed, and improves B/C values, is to improve B/C values to 0.35-
0.47。
It is of the invention that biochemical, combined treatment pyridoxal oxidation section waste water is added using oxidation, electrolysis, aided bleaching, no
Manganese dioxide resource can be only reclaimed, the problem of cost height, biochemical inapplicable can also be solved, achieve many things at one stroke.It is succinct efficient, low
Cost.
With reference to embodiment, the invention will be further described.
