Abstract
The utility model provides a novel underground water defluorination device which comprises a water inlet unit, a clearing unit, a spherical hydroxyapatite filtering unit and a quartz sand filtering unit, wherein the water inlet unit, the clearing unit and the spherical hydroxyapatite filtering unit are sequentially connected, the spherical hydroxyapatite filtering unit is arranged at the top of the clearing unit, and the quartz sand filtering unit is arranged at the top of the spherical hydroxyapatite filtering unit or independently arranged. The novel underground water defluorination device is simple in structure, convenient to use and low in cost, strengthens the removing effect of fluorine in underground water by means of induction of the spherical hydroxyapatite filtering unit, improves the removing efficiency of fluorinion, ensures high quality of outlet water, and particularly has adaptability on underground water with high initial concentration.
Description
Technical field
The utility model belongs to the ground water cleaning field, relates to a kind of Removal of Fluorine From Underground Water device.
Background technology
The groundwater pollution complex of China, except Shanghai City, all there is the groundwater pollution problem in national each province, relates to nearly hundred million people of population.Particularly taking in the fluorosis that causes behind the fluorine in the tap water, is worldwide serious problems.
Existing Removal of Fluorine From Underground Water technology mainly comprises coagulation sedimentation, activated alumina absorption method, electroosmose process, reverse osmosis method, ion exchange method, absorption method, bone black absorption and zeolite defluorination method etc., but all there is certain problem in various technology in actual application, it is applied have certain difficulty.Hydroxyapatite is for being used in the recent period a kind of respond well novel material of Removal of Fluorine From Underground Water, because material itself does not have toxic action to be subject to extensive concern.The form of hydroxyapatite comprises powder-material and form of spherical particles filtrate, and is applied in some Practical Projects.
