According to the invention, the problems of water pollution and microelement supplement for animal bodies are also solved; the method for utilizing the zinc ions in the zinc industrial wastewater resources has good ecological, economic and social benefits.
Description
Technical field
The invention belongs to sewage treatment area, be specifically related to a kind of method of zinc ion in recycling Zn Cr coating sewage.
Background technology
Water pollutes the environmental problem becoming a serious harm human health, and in recent years, trade effluent and city domestic sewage containing heavy metal are increasing, and it is particularly important for selecting the method rationally purifying sewage.
Ion-exchange-resin process is a kind of important method processed containing metallic element sewage, the amino contained in resin, light base isoreactivity group, sequestration, exchange reaction can be carried out with metal ion, thus remove metal ions in sewage, may be simultaneously used for concentrating and reclaim the metal of trace in solution, common ion exchange resin has cation exchange resin, anion exchange resin, chelate resin and humic acid resin etc..Ion-exchange-resin process equipment is simple, operates easily controllable, and process conditions are ripe, flow process is short, and resin can regenerate, and is widely applied at present in terms of sewage disposal.
But the metallic element of a lot of treated recovery do not obtain again with, this causes the waste of metals resources to a certain extent.
Although the content that metal trace element is in humans and animals body is few, but closely bound up with the existence of humans and animals and health, life is played vital effect.Their excess intake, deficiency, imbalance or shortage all can cause humans and animals body physiological abnormal to some extent or disease occurs.It should be noted that these trace element must directly or indirectly be supplied by soil under normal circumstances, but major part humans and animals tends not to obtain enough trace element by diet.According to scientific research, up to the present, it has been identified that the essential metal trace element relevant with health and lives has ferrum, copper, zinc, cobalt, manganese, chromium, nickel, molybdenum, vanadium, stannum, strontium, rubidium etc..This every kind metal trace element has its special physiological function.Although they are minimum at people's in-vivo content, but they are the most necessary to maintaining some the conclusive metabolism in human body.Once having lacked these required trace element, human body arises that disease, even threat to life.Relatively it is clear that the disease of about 30% is directly trace element deficiency or uneven caused.As zinc deficiency can cause mouth, eye, anus or external genital redness, pimple, eczema.And for example ferrum is one of main component constituting hemoglobin, and iron deficiency can cause iron deficiency anemia.Abroad once had been reported that: in body, iron content, zinc, zinc total amount reduce, and all can weaken immunologic mechanism (resist the disease strength), reduce resistance against diseases, and encouraged antibacterial and infect, and metainfective mortality rate is the highest.Trace element the most also plays very important effect at aspects such as disease-resistant, anti-cancer, life lengthening.
It is interpolation metal inorganic salt in food that tradition supplements the method for metallic element, but humans and animals body is relatively low to the absorption efficiency ratio of metal inorganic salt, it is unfavorable for that metallic element is utilized by body, and a lot of metal inorganic salt is easily generated adverse consequences to body toxic side effect, long-term taking.The metallic element of inorganic states can be changed into the metallic element of organic by microorganism, metallic element is made to be combined with macromole such as protein, form the form that body easily absorbs and utilizes, and the metallic element of organic belongs to bioactive substance, and human body is not had toxic and side effects.
In sum, a kind of recycling by metallic element in sewage of exploitation is fabricated to feed additive, solves water pollution problems and a supplementary animal body trace element difficult problem simultaneously, has good ecological benefits, economic benefit and social benefit.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, a kind of method of zinc ion in recycling Zn Cr coating sewage is provided, sewage water filtration containing zinc ion is obtained filtrate by the present invention, then zinc ion is adsorbed by filtrate by ion exchange resin, elution ionic exchanger resin obtains zinc ion concentrated solution, zinc ion concentrated solution is mixed with industrial or agricultural by-product, through fermentable, be dried and granulation obtain additive of organic zinc feed.
The present invention realizes in the following way:
1, a kind of method of zinc ion in recycling Zn Cr coating sewage, comprises the following steps:
(1) by the sewage water filtration containing zinc ion, filtrate is obtained；
(2) by filtrate by ion exchange resin, applied sample amount and ion exchange resin weight ratio are 6 ~ 10:1, and loading flow velocity is 1.0-2.0 BV/h；
(3) by NaCl solution, ion exchange resin being carried out eluting after absorption completely, obtain zinc ion concentrated solution, eluent and sewage weight ratio are 1:15 ~ 20, and elution flow rate is 0.5-1.0 BV/h；
(4) by zinc ion concentrated solution, industrial or agricultural by-product and microbial bacterial agent by weight 1:1000 ~ 2000:10 ~ 20 mix homogeneously, at room temperature fermentation 25-30 days, stirring in every 12 hours is once；
(5) after fermentation ends, tunning is dried；
(6) dried tunning is pelletized, obtain additive of organic zinc feed.
Preferably, any one during described ion exchange resin is D751 chelating ion exchange resin, D401 chelating ion exchange resin, IRC-718 chelating ion exchange resin.
Preferably, described eluate concentration is the NaCl solution of 6-10%.
Preferably, described industrial or agricultural by-product include distiller grains, Testa oryzae, Testa Tritici, Semen Maydis powder, bean cake, cassava starch dregs, beer residue, marc, Chinese herb residues, Pericarppium arachidis hypogaeae, wood bran, bark powder, coconut palm bran, changing food waste, Boiler Ash in more than one.
Preferably, described microbial bacterial agent includes yeast, lactic acid bacteria, bacillus subtilis, Bacillus licheniformis.
Advantages of the present invention and good effect:
1, the present invention solves water pollution problems and a supplementary animal body trace element difficult problem simultaneously, has good ecological benefits, economic benefit and social benefit.
2, the metallic element in sewage is recycled by the present invention, has saved resource, it is to avoid the wasting of resources.
3, metallic element is changed into organic from inorganic states by microorganism by the present invention, beneficially the absorption of animal and utilization.
