Abstract
The invention discloses a method for utilizing zinc ions in zinc industrial wastewater resources. The method includes the following steps: filtering the wastewater containing the zinc ions to obtain a filtrate; using a zinc exchange resin to adsorb the zinc ions in the filtrate; eluting the ion exchange resin to obtain a zinc-ion concentrated solution; mixing the zinc-ion concentrated solution with industrial and agricultural by-products, fermenting by microorganisms, drying and granulating to obtain organozinc feed additives. 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 the method for zinc ion in a kind of recycling Zn Cr coating sewage.
Background technology
Water pollutions becomes the environmental problem of a serious harm human health, in recent years, containing the trade effluent of heavy metal and city domestic sewage increasing, select the method for rationally purifying waste water to be very important.
Ion-exchange-resin process is a kind of important method processing containing metal element sewage, the amino contained in resin, light base isoreactivity group, huge legendary turtle conjunction, exchange reaction can be carried out with metal ion, thus removal metal ions in sewage, can also be used for the metal of trace in concentrated and recovery solution, common ion exchange resin has cationic ion-exchange resin, anion exchange resin, chelate resin and humic acid resin etc. simultaneously.Ion-exchange-resin process equipment is simple, and operation is easy to control, and process conditions are ripe, flow process is short, and resin can regenerate, and obtains extensive application at present in sewage disposal.
But the metallic element of a lot of treated recovery is not utilized again, and this causes the waste of metals resources to a certain extent.
Although the content of metal trace element in humans and animals body is few, with the existence of humans and animals and health closely bound up, vital effect is play to life.Their excess intake, deficiency, imbalance or shortage all can cause the physiological abnormal or generation disease of humans and animals body to some extent.It should be noted that these trace elements must directly or indirectly be supplied by soil under normal circumstances, but most of humans and animals does not often obtain enough trace elements by diet.According to scientific research, up to the present, be identified the essential metal trace element relevant with health and lives and have iron, copper, zinc, cobalt, manganese, chromium, nickel, molybdenum, vanadium, tin, strontium, rubidium etc.This often plants the physiological function that metal trace element has it special.Although they are minimum at people's in-vivo content, they are very necessary to some the conclusive metabolism maintained in human body.Once lack these required trace elements, human body just there will be disease, even threat to life.Relatively it is clear that the disease of about 30% is directly caused by microelement deficiencies or imbalance.As scarce zinc can cause mouth, eye, anus or external genital redness, papule, eczema.And for example iron is one of main component forming hemoglobin, and iron deficiency can cause hypoferric anemia.Once report was had abroad: in body, iron content, zinc, zinc total amount reduce, and all can weaken immunologic mechanism (resist the disease strength), reduce resistance against diseases, encourage bacteriological infection, and the metainfective death rate are also higher.Trace element disease-resistant, give protection against cancer, to promote longevity etc. in all also play very important effect.
The method that tradition supplements metallic element adds metal inorganic salt in food, but the absorption efficiency of humans and animals body to metal inorganic salt is lower, be unfavorable for that metallic element is utilized by body, and a lot of metal inorganic salt pair body toxic side effect, long-term taking easily produces adverse consequences.The metallic element of inorganic states can be changed into the metallic element of organic by microorganism, the large molecule such as metallic element and protein is combined, form the form that body easily absorbs and utilizes, and the metallic element of organic belongs to bioactivator, does not have toxic and side effect to human body.
In sum, a kind of recycling by metallic element in sewage of exploitation is made into feed addictive, 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
The object of the invention is to overcome the deficiencies in the prior art part, the method of zinc ion in a kind of recycling Zn Cr coating sewage is provided, sewage water filtration containing zinc ion is obtained filtrate by the present invention, then filtrate is adsorbed zinc ion by ion exchange resin, elution ionic exchanger resin obtains zinc ion concentrate, zinc ion concentrate is mixed with industrial or agricultural accessory substance, obtains additive of organic zinc feed through fermentable, drying and granulation.
The present invention realizes in the following way:
1, the method for 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) filtrate is passed through 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) carry out wash-out by NaCl solution to ion exchange resin after absorption completely, obtain zinc ion concentrate, eluent and sewage weight ratio are 1:15 ~ 20, and elution flow rate is 0.5-1.0 BV/h;
(4) zinc ion concentrate, industrial or agricultural accessory substance and microbial bacterial agent are mixed by weight 1:1000 ~ 2000:10 ~ 20, at room temperature ferment 25-30 days, within every 12 hours, stirs once;
(5) after fermentation ends, tunning is dried;
(6) dried tunning is granulated, obtain additive of organic zinc feed.
Preferably, described ion exchange resin is any one in 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 accessory substance comprises more than one in vinasse, rice bran, wheat bran, corn flour, dregs of beans, cassava starch dregs, beer residue, pomace, Chinese herb residues, peanut shell, wooden chaff, bark powder, coconut palm chaff, changing food waste, Boiler Ash.
