Description
Technical field
The invention belongs to field of environment protection, it is related to a kind of heavy metal pollution of water body recovery technique, more particularly to a kind of stone
Modified heavy metal in water compound adsorbent of black alkene and preparation method thereof.
Background technology
It is raw that heavy metal is primarily referred to as lead (Pb), cadmium (Cd), mercury (Hg), chromium (Cr), arsenic (As) etc. in environment and health field
The significant element of thing toxicity, also refers to the general heavy metal such as copper (Cu), zinc (Zn), cobalt (Co), nickel (Ni).Heavy metal or its chemical combination
Thing pollution on the environment is referred to as heavy metal pollution.Its main cause is to include industrial wastewater waste gas discharge, mining, sewage
Content of beary metal increases during the factor of human activity such as irrigation cause environment, beyond normal range (NR), and causes environmental quality to deteriorate.
Heavy metal pollution is different from other problem of environmental pollutions.For example in organic contamination, many organic compounds can be with
By nature physics, chemical or biology purification in itself, make harmfulness reduction or release.And heavy metal has enrichment
Property, it is difficult to degrade in the environment.Even if during therefore the heavy metal of concentration very little flows into environment, will also result in pollution.For example it is very low
The heavy metal of concentration flows into rivers with waste water, can be enriched with the organism such as algae and fishes and shrimps shellfish and produce food chain concentration, from
And cause public hazards.
Harm of the different heavy metals to organism is different：Lead can by skin, alimentary canal, respiratory tract enter in vivo with
Various organs are affine, cause anemia, nervous function imbalance and injury of kidney；Feeblemindedness, reaction are often shown as after poisoning late
The slow poisoning symptom such as blunt, anaemia.Frequent origins have some foods such as mushroom, agaric, aloe, tealeaves, aquatic products and some in
Medicine, paint, battery, smelting, hardware, machinery, plating, cosmetics, hair dye, muffle painting dishes tableware, fire coal etc..The world
Lead tolerance is to greatest extent 0.01mg/L in health organization regulation drinking water.
Copper is the metal that the mankind use earliest, and nineteen twenty-eight Hart has found that copper is the essential trace element in organism.But
Excessive copper can cause the internal organs in human body to cause burden, particularly liver and courage again, after both organs go wrong, maintain
Metabolism in human body will get muddled, cirrhosis, liver ascites, or even even more serious.The exploitation and smelting of copper mine, metal
Processing, machine-building, steel production etc. easily bring the pollution of heavy metal copper.Copper content in World Health Organization's regulation drinking water
It is to greatest extent 2.0mg/L.
Cadmium is mainly accumulated in kidney and liver after entering human body, infringement renal function, bone and digestive system；In acute cadmium
Poison can cause vomiting, suffer from diarrhoea, the loss of consciousness etc., and cadmium and its compound have certain teratogenesis and carcinogenic effect.Frequent origins
Have in the foods such as rice, mushroom, agaric, aquatic products, cadmium content is to greatest extent in World Health Organization's regulation drinking water
0.003mg/L。
Manganese is one of trace element necessary to human body and animals and plants, but the manganese of excess intake then can be bad to body generation
Effect.Manganese mainly enters body by respiratory tract in industrial production, and the system such as nerve, reproduction, breathing to people produce it is different
The infringement of degree.
Chronic Mn Poisoning is a kind of progressive disease, even if disengaging, the state of an illness still may proceed to development.And the purposes of manganese is non-
Often extensively, almost it is related to the every aspect of human lives, especially in the industrial production.In World Health Organization's regulation drinking water
Manganese content is to greatest extent 0.5mg/L.
Mercury is extremely toxic substance, based on organic mercury poisoning, the World Health Organization regulation drinking water in mercury content to greatest extent
It is 0.001mg/L.Mercury poisoning shows as finger, lip and tongue numbness, babble, visual field diminution, ataxia and god
Through system damage.Severe patient can occur paralysis, limbs deformation, dysphagia even death.Common mercury pollution source have cosmetics,
Aquatic products, instrucment and meter plant, salt electrolysis, precious metal smelting, illuminator lamp, dental material, fire coal etc..
Zinc is the necessary trace element of human body, if but it is too high in people's in-vivo content, it will suppress the activity of phagocyte and kill
Bacterium power, weakens the immunologic function of human body and resistance, and disease susceptibility is increased.Main zinc pollution source have zinc ore exploit,
The industrial discharge such as smelting processing, machine-building and zinc-plated, instrument and meter, organic synthesis and papermaking.The World Health Organization specifies
Zinc content is to greatest extent 3.0mg/L in drinking water.
Arsenic and its compound are confirmed to be carcinogenic substance.Arsenic can disturb the breathing of human body enzymatic activity and cell, divide and numerous
Grow and cause dysbolism；Acute arsenic poisoning: Report shows as kidney intestinal inflammation, severe patient can cause central nervous system benumb and
It is dead；Arsenicalism shows as neurasthenia disease group, cutaneous pigmentation, excessive keratinization, peripheral neuritis etc..Arsenic is normal
See agricultural chemicals and residue of veterinary drug.Arsenic content is to greatest extent 0.01mg/L in World Health Organization's regulation drinking water.
Chromium has stimulation and corrosiveness to respiratory tract, causes pharyngitis, bronchitis etc..If eat by mistake can cause abdominal discomfort and
Diarrhoea, allergic dermatitis, eczema, the chromium of sexavalence is two class carcinogens.Cosmetic material, leather preparation, metal parts Du Chrome
Partly, common chromium in commercial pigments, tanning, rubber and ceramic raw material etc..The World Health Organization regulation drinking water in chrome content most
Limits are 0.05mg/L.
Nickel poisoning can cause chronic bronchitis, decline in pulmonary function, serious caused lung cancer.Meanwhile, it is excessive
Iron is also harmful to human body, can cause palpitate quickly, blood vessel blockage, hypertension.Contain in World Health Organization's regulation drinking water
Some nickel and iron are at most no more than 0.02mg/L and 0.2mg/L.
The research to heavy metal pollution of water body starts from the sixties in last century in the world, and China then opens from the eighties in last century
Begin that just heavy metal pollution of water body is launched to study.The method for the treatment of heavy metal wastewater thereby common at present can classify as three kinds：Physics
Method, bioanalysis and chemical method.Wherein Physical including evaporation, change water law and dilution method etc., these methods can seldom cause two
Secondary pollution, but cost is larger and limitation is obvious, therefore applicable scope is smaller.Biological treatment be using animals and plants and
The method of microbial material and its vital metabolic active process heavy metal in waste water.Influence of the biological treatment to environment is smaller,
With very wide application prospect, but process cycle is more long, and its research is also needed deeply to carry out.Chemical method mainly includes precipitation
And flocculence, oxidation-reduction method, absorption method and electrolysis.The method compares efficient quick, but easily produces secondary pollution, general to use
In treatment concentration of heavy metal ion content waste water higher.
The content of the invention
Present invention solves the technical problem that：In order to overcome the defect of prior art, a kind of effect on environment of acquisition is small, treatment
Cycle is short, has a wide range of application, and does not result in the heavy metal in water adsorbent of secondary pollution, the invention provides a kind of Graphene
