Description
Technical field
The present invention relates to environmental wastewater process field, particularly a kind of method and device thereof that utilizes the fixing arsenic in waste water of the efficient Quick Oxidation of glow discharge.
Background technology
Arsenic (As) is a kind of element extensively distributing in the earth's crust, and is acknowledged as a kind of poisonous carcinogenic substance.The compound of As has trivalent and two kinds of forms of pentavalent, and toxicity and the mobility of As (III) are larger.Research shows, with AsO
3 3-as (III) ratio existing is with AsO
4 3-the toxicity of the As (V) existing will exceed 60 times.Arsenide is when the production fields such as mining, smelting, glass manufacture, agricultural chemicals and wood preservative are used widely, cause a considerable amount of arsenic compound entered environments, and be present in water body, soil, plant, animal, marine organisms and human body with different shape by chemical process and bio-transformation effect, and form circulation between each arsenide.
According to the research of the World Health Organization, as long as there is a small amount of As in tap water, be just enough to the health of human body to endanger.Long-term drinking, containing the water of As, may cause a series of health problems such as Skin pigmentation, skin keratin, skin carcinoma, bladder cancer, hypertension, cardiovascular and cerebrovascular disease, DPN, diabetes.In view of being on the rise that the significant damage of As to HUMAN HEALTH and As pollute, 1993, WHO took the lead in the desired value of As in tap water to be down to 10 μ m/L by 50 μ m/L.Subsequently, Japan, European Union, the U.S. are also decided to be 10 μ g/L by tap water As standard separately respectively." drinking water sanitary standard " that China is used at present (GB5749-2006) requires the peak concentration of As in tap water must be lower than 10 μ g/L.Therefore be very urgent for the processing that contains High Concentration of Arsenic trade effluent.
At present, coagulation is widely used except aluminium, iron-based flocculation agent in As method, and the method is mainly the adsorption arsenic-adsorbing that utilizes coagulating agent powerful, then by filter or with filter membrane except the arsenic in anhydrating.Experimental result shows, molysite to the removal efficiency of arsenic apparently higher than aluminium salt.Molysite is most economical, the most effective precipitation agent.But As (III) toxicity is large and be difficult to be flocculated realization and remove completely.And the toxicity of As (V) is relatively little, and be easily adsorbed, be able to efficient removal.Therefore before applying flocculation technique arsenic removal, need As (III) to carry out preoxidation, AS (III) initial oxidation is become to As (V), and then remove.Conventional oxygenant mainly contains chlorinated lime, hydrogen peroxide, chlorine, ozone and Manganse Dioxide etc.But the method need to add a large amount of flocculation agents, produce a large amount of arsenic-containing waste residues and also can cause secondary pollution, therefore make the application of the method be restricted.
Therefore for the existing defect about trivalent arsenic treatment technology, be badly in need of developing a kind of green, efficient trivalent arsenic treatment technology.Single stage method realizes arsenious Quick Oxidation, removing by arsenic from waste liquid, and reduce final produce arsenic-containing waste residue amount.Scorodite is a kind of ferric arsenate crystal, and its solubleness is little, stable in properties, arsenic content can be up to 30%.Therefore for the arsenic-containing waste water of large concentration, arsenic can be converted into ferric arsenate crystal, reach the object of solid arsenic.Conventional method is under 95 ° of C conditions, to control neutralisation higher than 150 ° of C hydrothermal methods or under atmospheric atmosphere in temperature, but these method costs are higher, the long large-scale application that is unfavorable for of required time.
Direct current glow discharge plasma body water technology is a kind of novel high-level oxidation technology, cardinal principle is that the gas around high voltage needle electrode will be crashed to pieces into positive ion and electronics under the effect of high direct voltage, these particles accelerate to obtain high-energy under high-tension effect, thereby bump with other material, thereby produce new electronics, ion and free radical, chemical substance etc.At present, this kind of technology has been applied to the processing of Organic Pollutants in Wastewater widely, utilizes the material such as hydroxyl radical free radical and hydrogen peroxide producing to realize organic final removal.But this kind of technology is applied to the processing research that contains poisonous mineral ion and also do not obtain everybody and pay close attention to comprehensively.
