A water treatment device for adsorbing fluoride ions in water

Abstract

The invention discloses a water treatment device capable of adsorbing fluoride ions in water. The water treatment device comprises an electrolysis tank, a water outlet tank and a communicating part, wherein two ends of the communicating part are separately communicated with the electrolysis tank and the water outlet tank; the communicating part comprises a water supply pipeline, a feeding part and a lid body; the feeding part comprises a first pipeline and a juice squeezer; the juice squeezer takes the shape of a cone; a plurality of first through holes are formed in the surface of the juice squeezer; a plurality of protruding edges of which the sections are trigonal are also arranged on the conical surface of the juice squeezer; the lid body consists of a circular tank and a closed end; the two ends of the circular tank are unclosed, and the closed end can move in the length direction of the circular tank; a pull rod is perpendicularly fixed to the closed end; an annular sealing ring for preventing the closed end from moving out of the circular tank is arranged at one end of the circular tank. The water treatment device disclosed by the invention can be dual-purpose, and is small in occupied size, high in fluoride removing rate, and short in fluoride removing time; besides, when a citizen wants to drink fruit juice, the water treatment device can be used as the juice squeezer, so that the water treatment device is quite convenient and multi-functional.

Description

technical field

[0001] The invention belongs to the technical field of water treatment devices, and more specifically, the invention relates to a water treatment device for absorbing fluorine ions in water. Background technique

[0002] my country's drinking water standard (GB5749-2006) stipulates that the fluorine content in drinking water shall not exceed 1mg / L. Long-term drinking of high-fluoride water can cause fluorosis, manifested as dental fluorosis and skeletal fluorosis. Adsorption defluoridation is currently the most widely used method in water treatment defluoridation process. Adsorbents mainly include activated alumina, bone char and zeolite, but the adsorption method requires a large amount of adsorbents, and the adsorbents are usually some chemical substances. There will be a certain amount of adsorbent in the water, which will affect the body if people take it for a long time. At the same time, it takes a long time to adsorb fluorine with an adsorbent. In or...
