Put.
Background technology
Arsenic is a kind of toxicity very strong heavy metal element, and it will exist in the environment to be produced to human body, aquatic animals and plants etc.
Have a strong impact on.Naturally occurring arsenic in the form of inorganic compound to be widely distributed in soil, rock forming mineral.Arsenic compound is generation
The carcinogenic substance that many authoritative institutions such as boundary's health organization are assert, the current whole world has more than 100,000,000 populations by drinking water arsenic pollution
Threat, only China's arsenic poisoning harm lesion population of exposure just be up to 15,000,000 people, patient diagnosed exceed tens of thousands of people.For a long time
Drink the exceeded water of arsenic, it would be possible to cause Skin pigmentation, skin keratin, cutaneum carcinoma, liver cancer, angiocardiopathy etc. one to be
Row health problem.In order to control drinking water, grain, veterinary antibiotics, aquatic animal (such as fish) different approaches to cause human body etc.
Arsenic exposure, China carried out strict regulation by the form of standard to different arsenic in water environment concentration limits.For example,
Require that four classes and its above arsenic in water body concentration should be less than 50 μ g/L in quality standard of water environment；In industrial wastewater discharge standard
Regulation, which drains into arsenic concentration in the industrial wastewater in water body, should be less than 0.50mg/L.China is newest《Standards for drinking water quality》
(GB5749-2006) more strict regulation is made that to arsenic concentration limit value, it is desirable to which Arsenic in Drinking Water Cmax have to be lower than
10μg/L。
The removal technology of arsenic is the focus and difficulties studied both at home and abroad in water.Many research and technology developments
Eye develops substantial amounts of arsenic removal new technology and new method in the removal of Arsenic in Drinking Water, such as absorption, flocculation-precipitation-filtering, wadding
Solidifying-direct filtering, electrodialysis, ion exchange, UF membrane etc..On except arsenic adsorbent material, develop activated alumina, red mud,
Modified activated carbon, FeOOH,Manganese sand, hydration Mn oxide, ferric oxide-alumina are combined
