Description
Technical field
The utility model belongs to feedwater and waste disposal plant field, further refers to a kind of water treatment device that exceeds standard for iron, manganese, fluorine, arsenic in the underground water.
Background technology
Underground water is the important component part of water resources.Along with the day by day raising of people's people life, the development of town development, groundwater resource receive people's especially concern.Underground water often contains too high iron, manganese, and some regional underground water also contains fluorine and arsenic has seriously affected the use of people for underground water.
China's " drinking water sanitary standard " is middle regulation (GB5749-2006): iron＜0.3mg/L, and manganese＜0.1mg/L, content of fluoride must not surpass 1.0mg/L, and arsenic content must not surpass 0.05mg/L.When underground water surpasses above-mentioned standard, just should process." drinking water sanitary standard " (GB5749-2006) enforcement in 1 day July in 2007 that China is new, on July 1st, 2012 was large time limit, technology and the device of the applicable new standard of research and development are transformed significant with the upgrading of instructing tap water.
In technology in the past, generally adopt the natural oxidation method to remove iron, contact oxidation method demanganization.Iron, manganese exceed standard in the underground water, mainly exist iron to exceed standard or iron and the manganese two kinds of situations that exceed standard simultaneously, generally all utilize principle of uniformity, and the iron, the manganese that are about to dissolved state are oxidized to undissolved ferric iron or tetravalence manganese, again through filtering the purpose that namely reaches removal.The chemical reaction of iron and manganese alters a great deal because of the impact of environmental factors, and the redox potential of iron is lower than manganese, and the speed of oxidation is fast than manganese, so iron is than the easy removal of manganese.The demanganization technology becomes difficult point.And fluorine, arsenic content overproof in the underground water generally adopt the adsorption filtration method, coagulant sedimentation, embrane method etc.In the adsorption filtration method, take activated alumina as sorbent material, its absorption filtering velocity is low, generally can only reach 2 ~ 3m/h, continuous operating time is short, limited the performance of capacity of equipment, and embrane method is expensive, and operation easier is large, and energy consumption is high.
As: number of patent application 201110404135 discloses the method that a kind of film combination process is removed ferrimanganic in the water body, comprises water body is carried out the aeration oxidation, then will filter in delivering to continuous membrane filter through the water of aeration oxidation.Main flow process is: the aeration oxidation, and------water collecting basin---continuous membrane filter---produces water tank to coagulating sedimentation.
Patent application 200810021420 discloses the exceed standard removal method of ferrimanganic of a kind of underground sea water, by ozonation aerated processing, so that Fe and Mn is oxidized to water-fast precipitation, adsorption filtration; Again through the adsorption filtration of overdone matter manganese sand.Major equipment foam separator (1), Venturi-type Liqiud-gas mixing device (3), sand-bed filter (4) and ripe matter filtration with manganese sand device.
Above technology all has certain removal effect to iron, manganese, fluorine or arsenic, but does not also have a kind of device that can effectively remove these several materials that exceed standard simultaneously at present.
