Description
Technical field
The present invention relates to sewage treatment area, more particularly to one kind to be used for heavy metal-polluted water process material and its preparation side
Method.
Background technology
China's year water total amount has broken through 6000 billion cubic meters at present, and water resource of per capita only has 2100 cubic metres, is only
The 28% of world's per capita share.National annual water deficit billion cubic meter more than 500,2/3rds urban water shortage, the north has 9
Provinces and cities account for water and are less than 500 cubic metres, the far minimum standard (1000 cubic metres) less than international regulations per capita, are listed in the world
One of poor land that abounds in rivers and lakes.And with the fast development of social economy, China's sewage quantity has reached 82,000,000,000 tons at present, and it is 20 to increase in year
Hundred million tons, daily quantity of wastewater effluent reaches 200,000,000 tons.Heavy metal ion sewage refers to mining and metallurgy, machine-building, chemical industry, electronics, instrument etc.
The sewage containing heavy metal ion discharged in industrial processes, such as mercury, lead, cadmium, nickel.And heavy metal ion sewage accounts for often
The 20-30% of year total sewage.Because heavy metal ion has larger toxicity, high mobility and low poisoning concentration, such as
If people eats 0.1g mercury and will be poisoned to death.Heavy metal ion is difficult to be degraded by microorganisms in water body, and in microorganism
Easily enrichment.The health of the mankind is caused serious injury, human carcinogen, deformity, gene mutation can not only be made, and in people
It can not be metabolized in body.Human health is directly or indirectly mainly influenceed by drinking water, skin contact, food chain approach.
In the discharge process of industrial wastewater, there is considerable degree of heavy metal element to be deposited in natural water body, in these heavy metal ion
It is especially maximum with the toxicity of mercury, cadmium, chromium, lead in pollutant.If mercury is in the maximum element of heavy metal ion pollution Poisoning.It is inorganic
Mercury salt and organomercurial compound have harm to human body.But their effects to human body and differ.Inorganic mercury salt produces poison
Property basic reason be that mercury ion is combined with zymoprotein, suppress the activity of various enzymes, make cell normal function occur obstacle.
And organomercurial compound is maximum with methyl Hg toxicity because it has solubility ratio big in water in fat, into human body after it is several
It can all absorb, be not easy to excrete again, accumulation invades central nervous system in vivo, destroys the cerebrovascular, shows as four limbs
Numbness, speech disorders, visual field diminution, hearing loss etc..It is exactly because the discharge of caustic soda process industry is given up such as the minamata disease of Japan
Contain mercury in water, caused by after becoming organic mercury through biological agent；And for example itai-itai, it is by zinc metallurgy industry and cadmium electroplating industry
Caused by the cadmium discharged.The lead of motor vehicle exhaust emission enters in environment through processes such as Atmospheric Diffusions, causes the dense of current earth's surface lead
Degree has been significantly increased, and causes the uptake of lead in modern age human body to add about 100 times than primitive man, compromises health.
Injury of the heavy metal ion to human body is very big.So heavy metal in water ionic soil has become global problems.Therefore, how soon
Speed, efficiently go heavy metal ion in water removal to turn into the problem of field of water pollution control is in the urgent need to address, there is important ring
Protect meaning.
Publication No. 104722272A patent discloses a kind of new waste water sewage disposal sorbing material and its prepares work
Process, the invention include three Organic Modification of Bentonites, bentonite immobilization and continuous treatment industrial wastewater containing phenol parts,
If this invention sewage intermediate ion excessive concentration can compress bentonite clay particle electric double layer, suppress bentonitic scattered and diffusion, very
To making bentonite produce cohesion and coalescence, therefore sewage disposal can not be effectively applied to, it is ineffective, cost is higher.
Publication No. 103601433A patent discloses a kind of method for preparing sewage disposal efficient dephosphorization material, should
The preparation of invention material comprises the following steps (1) and clay, ordinary cement, white lime and oil shale waste is dried into 12-24 at 105 DEG C
Hour；(2) by dried 120-180 grams of the clay of step (1), 40-60 grams of ordinary cement, 80-120 grams of white lime and oil shale
80-120 grams, add water 190-280ml, be passed through 0.2L/min air using aerator, be sufficiently stirred 10-25 minutes, that is, obtain
Mixture；(3) it is 3.5-4.5mm particles to be put into comminutor and particle diameter is made；(4) it is dirty in 105 DEG C of dry 12-24 hours, i.e. acquisition
Water process efficient dephosphorization material, this invention heavy metal ionic adsorption is poor bad to wastewater treatment efficiency, preparation technology
It is complicated.
