Drinking water filtering system for high-fluorine region based on dental fluorosis prevention

Abstract

The invention discloses a drinking water filtering system for a high-fluorine region based on dental fluorosis prevention, and belongs to the field of drinking water filtration, the drinking water filtering system for the high-fluorine region based on dental fluorosis prevention comprises a tank body, the upper end of the tank body is communicated with a regeneration flushing pipe, and the lower end of the tank body is communicated with a fluorine removal water inlet pipe; a blocking cylinder is fixedly connected to the inner wall of the tank body, a containing groove is formed in the side wall of the blocking cylinder, an existing defluorination tank is improved, filter materials are arranged to be in a movable splicing mode, washing in the regeneration process is facilitated, fan-shaped filter material bodies which can be spliced into a cylindrical shape are arranged, and the filter materials are combined in the filtering process, so that the filtering efficiency is improved. The fan-shaped filter material bodies are spliced to achieve a normal filtering function, the fan-shaped filter material bodies are dispersed during washing to increase the contact area and range of a regeneration solution and the filter material, so that the regeneration effect is effectively improved, and in addition, the spliced fan-shaped filter material bodies prolong the filtering path and effectively improve the filtering effect.

Description

technical field [0001] The invention relates to the field of drinking water filtration, in particular to a drinking water filtration system for high-fluoride areas based on the prevention of dental fluorosis. Background technique [0002] The fluoride-containing areas of groundwater in my country are widely distributed, and long-term drinking of water with high fluoride content can cause chronic poisoning, especially serious damage to teeth and bones. Mild cases of dental fluorosis manifest as enamel damage, premature tooth loss, etc., while severe cases may cause bone and joint pain, even bone deformation, hunched over, etc., and completely lose the ability to work. So the harm of high fluorine water is serious. my country's drinking water standards stipulate that the fluorine content should not exceed 1mg / L. [0003] For defluoridation, the adsorption filtration method is often used. When the raw water flows through the defluoridation device, the core filter layer inside...

AI Technical Summary

Problems solved by technology

Most of the current defluoridation equipment is equipped with a filter material regeneration device. The method is to flush the top of the tank with a water pipe containing a regeneration solution. Under the area in contact with the solution, the washing time is short, so the regeneration effect is not good
