Description
Technical field
The invention belongs to sewage treatment area, be specifically related to the method for magnesium ion in a kind of recycling magnesium industry 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 magnesium deficiency 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, magnesium, magnesium 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.
