Description
Technical field
The present invention relates to a kind of drinking water treatment equipment, specifically is a kind of built-up type defluoroing water treatment facility.
Background technology
Fluorine extensively is present in the natural water, all contains fluorine in each tissue of human body, but mainly accumulates in tooth and the iliacus.Suitable fluorine is that human body is necessary, and excessive fluorine has harm to human body, and Sodium Fluoride is 6-12 grams to people's lethal quantity, and tap water contains 2.4-5 mg/L then skeletal fluorosis can occur.Fluorine concentration is less than 1.0 mg/L in China regulation tap water, and fluorine-containing suitable concentration is 0.5 ~ 1.0mg/L in the tap water.
According to market study and grasp data analysis, the whole nation is except that Shanghai City at present, and all there is the tap water fluorine content problem that exceeds standard in other area in various degree dissimilarly.The most serious province is Shanxi Province and area, the Inner Mongol.The tap water high fluorice region mainly is distributed in Changbaishan area, mountain region, the east area of the Liao River, coextensive with eastern and southern Liaoning Province, middle part, loose distant Plain, middle part, the Yellow River and Huai He River sea plain, basin, middle part, Shanxi Province, Nei Mongol Plateau, northwest landlocked basin towards flood section inclined plain leading edge area, hot spring range of distribution, hills, the southeast and southern Tibet hot spring area.Generally, be up to 35mg/l greater than 5mg/l.1182 counties (city) that relate to 29 provinces and cities, population nearly 200,000,000.Wherein drinking water type exceeds standard and is main type, accounts for 990 counties (city).
The long-term drinking water of high fluorine content is very big to health harm, will cause osteoporosis, ostealleosis, even paralysis, disability.
At present, drinking water defluorination method both domestic and external mainly contains absorption method, electroosmose process, reverse osmosis method and electrocoagulation, and wherein, the adsorption filtration method is used the widest, is applicable to the processing of tap water.Current, the adsorptive defluorination material kind of China's development, production is more, for example PAC soup, HAP-F; Activated alumina etc., but use a kind of strainer merely, the content of fluoride ion of handling in the water of back can not accurately be controlled; In case the content of fluoride ion value of being above standard in the water explains that the adsorptive power of filtrate is not enough, need in time to change filtrate; Content of fluoride ion in the water is reduced to below the standard value, and this equipment filtrate is changed frequent, and is quite restricted in the use.Might make in the water fluorine content low excessively and newly change filtrate, HUMAN HEALTH is not had benefit yet.Therefore develop a kind of adsorptive defluoroing water treatment facility of handling content of fluoride ion in the water of back of can accurately controlling is necessary very much.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of built-up type defluoroing water treatment facility, can accurately control and handle content of fluoride ion in the water of back, prolongs the filtrate replacement cycle, is of value to HUMAN HEALTH.
To achieve these goals; The technical scheme that the present invention adopts is: a kind of built-up type defluoroing water treatment facility; Comprise water inlet pipe, medium filter, defluorination strainer and rising pipe, also comprise defluorination medicinal liquor barrel and dosing pump, be communicated with PAC defluorination medicinal liquor barrel between water inlet pipe and the medium filter; Be provided with dosing pump between water inlet pipe and the PAC defluorination medicinal liquor barrel; Described water inlet pipe connects the water-in of medium filter through valve a, and the water outlet of medium filter is connected to the water-in of defluorination strainer through valve g and valve c, and the water outlet of defluorination strainer passes through valve e and is connected with rising pipe.
As preferably, medium filter is provided with counter-flushing pipeline, and the medium filter water outlet is connected with water inlet pipe through valve h, and the medium filter water-in passes through valve b and is connected with waste pipe.
As preferably, the defluorination strainer is provided with counter-flushing pipeline, and defluorination strainer water outlet is connected with valve g through valve f, and defluorination strainer water-in passes through valve d and is connected with waste pipe.
As preferably, be provided with line mixer between defluorination medicinal liquor barrel and the medium filter.
As preferably, in the defluorination medicinal liquor barrel PAC soup.
As preferably, the defluorination strainer is a HAP-F defluorination strainer.
The present invention has increased the defluorination medicinal liquor barrel before traditional defluorination strainer; Use the defluorination strainer fluorion in dewatering of making a return journey under the general case,, increase dose through dosing pump in case the fluorinion concentration in the water is too high; Can reduce the content of fluorion in the water; Fluorinion concentration in water is low excessively, reduces dose through dosing pump, can increase the content of fluorion in the water.To sum up,, thereby accurately control content of fluoride ion in the water all the time in standard value range, can prolong the filtrate replacement cycle, increased the work-ing life of equipment, be of value to HUMAN HEALTH again through dosing pump control defluorination amount of liquid medicine.
