Description
Technical field
The present invention relates to technical field of sewage, specifically a kind of heavy metal-polluted water treatment agent and preparation method thereof.
Background technology
Heavy metal wastewater thereby refers to discharge in the industrial processes such as mining and metallurgy, machine-building, chemical industry, electronics, instrument containing weight
The waste water of metal.Heavy metal wastewater thereby is arranged essentially from enterprises such as mine, smelting, electrolysis, plating, agricultural chemicals, medicine, paint, pigment
The waste water for going out.The species of heavy metal in waste water, content and existing forms are different with different manufacturing enterprises.Heavy metal wastewater thereby is to one
One of environmental pollution most serious and the industrial wastewater maximum to mankind's harm, its water quality and quantity is relevant with production technology.In waste water
Heavy metal can not typically decompose destruction, can only shift its existence position and change its Material Form.Heavy metal pollution and other
The pollution of organic compound is different.Many organic compounds can be by the net of nature physics, chemistry or biology in itself
Change, make harmfulness reduction or release.And heavy metal has enriching, it is difficult to degrade in the environment.Current China is due in a huge sum of money
In exploitation, smelting, the process of category, many heavy metals such as lead, mercury, cadmium, cobalt etc. is caused to cause sternly into big gas and water, soil
The environmental pollution of weight.The heavy metal such as discharged with useless heavy metal mercury water, even if concentration is small, can also accumulate in algae and bed mud
It is tired, adsorbed by fish and shellfish body surface, food chain concentration is produced, so as to cause public hazards.Metal is favourable in water body or harmful not only takes
Depending on the species of metal, physicochemical property, but also concentration and the valence state of presence and form depending on metal, even if beneficial
Metallic element concentration also has violent toxicity more than a certain numerical value, animals and plants is poisoned, or even dead.
At present, countries in the world process for treating heavy-metal waste water mainly has three classes：The first kind is that heavy metal ions in wastewater is led to
Cross and the method that chemical reaction is removed occurs, including neutralization precipitation method, sulphide precipitation, ferrite coprecipitation, electronation
Method, electrochemical reducing and high molecular heavy metals trapping agent method etc., but this method reaction time is more long, governance efficiency compared with
It is low；Equations of The Second Kind is the side for making the heavy metal in waste water be adsorbed under conditions of its chemical form is not changed, concentrated, be separate
Method, including absorption, solvent extraction, evaporation and freezing method, ion exchange and UF membrane etc., complex treatment process, treatment cost compared with
It is high；3rd class is the method by the effect removal heavy metal in waste water such as flocculation, absorption, accumulation, enrichment of microorganism or plant,
Including bioflocculation, biochemical process and plant ecological repair etc., this method exist high cost, technology it is immature, hold
Easily cause the shortcoming of biological pollution.Therefore, in the urgent need to a kind of governance efficiency is high, low cost, administering method are simple, do not result in
The heavy metal-polluted water treatment agent of biological pollution.
