Background
Fluorine is one of the trace elements necessary for human bodies, but high-fluorine water can cause fluorosis after being drunk for a long time, and the human health can be seriously influenced, so the world health organization publishes the regulation that the fluorine content of drinking water can not exceed 1.5 mg/L. The research of the prior defluorination water treatment method is highly emphasized by various countries, and the defluorination water treatment method published by the earlier research mainly comprises a coagulation sedimentation method, a chemical precipitation method, an electrodialysis method, an electrocoagulation method, a reverse osmosis method, a nanofiltration method, an ion exchange method, an adsorption method and the like, wherein: a large amount of calcium-aluminum plasma can be left by a chemical precipitation method and a coagulation sedimentation method, and the method is mainly used for treating industrial wastewater; because high-fluorine water is mainly distributed in regions with severe environment, complex terrain or water and electricity shortage, the effect of removing fluorine by using an electrodialysis method, an electrocoagulation method, a reverse osmosis method, a nanofiltration method and the like is excellent, but the high-fluorine water is difficult to popularize and apply due to the defects of complex devices, expensive equipment, high use cost and the like. The ion exchange resin method is difficult to be widely applied due to low anti-interference capability. The adsorption method is the most common drinking water defluorination treatment method at present, but the filter material needs to be regenerated, and the problems of use cost, defluorination efficiency and the like exist, so that the practical application of the adsorption method is limited. In order to overcome the defects of the prior art, the applicant has proposed a preparation method of a polyaluminium chloride/hydroxyapatite copolymerization material, see the Chinese patent application 201410743901.X, the method comprises the preparation of a polyaluminium chloride semi-finished product, the preparation of a hydroxyapatite semi-finished product and the preparation of a copolymerization material, the polyaluminium chloride/hydroxyapatite copolymerization network structure material is synthesized by the copolymerization method, compared with the existing defluorination material, the defluorination capacity is improved by 3 times compared with that of a single hydroxyapatite defluorination filter material, and is improved by 5 times compared with a specific activated alumina defluorination filter material; the network structure of the material is beneficial to the function of capturing aluminum ions and hydroxyapatite powder in the water body, and the problems of standard exceeding of the aluminum ions in the water body and water body clarity are solved; meanwhile, the polyaluminium chloride active component in the copolymerization material can promote the continuous regeneration of the hydroxyapatite, and the service life of the material is prolonged. However, this method also has the following significant disadvantages: firstly, the content of aluminum ions in the aluminum-based water treatment material is within a standard range, but is still higher than that of a non-aluminum-based water treatment material, so that the risk of overproof aluminum ions exists; secondly, the process and equipment for applying the aluminum-based water treatment material are complex, and the process of filtration, coagulation, precipitation and the like is required, so that the occupied area of the equipment is large, and the operation cost is high; and thirdly, the polymeric aluminum chloride/hydroxyapatite copolymer material has the problem of reduced defluorination effect at low temperature.

The problem to be solved by the scheme is as follows: the cleaning efficiency and the filtering effect are improved. The helical extrusion grooves serve to extend the distance of the filtration channels. However, water treatment based on the filtration principle can only filter out granular solids in raw water, at most some colloids can be removed, and substances incapable of removing ions, such as fluoride ions and calcium ions, cannot be removed by filtration.

Although the filtration effect can be increased by extending the filtration path, it is essentially filtration and cannot remove fluorine ions, calcium ions, and the like in the raw water.
How to overcome the defects of the prior fluorine removal water treatment method and the corresponding fluorine removal equipment becomes one of the key problems to be solved urgently in the technical field of the current water treatment materials.
