Water treatment system for removing fluorine ions with different concentrations in water

Abstract

The invention provides a water treatment system for removing fluorine ions with different concentrations in water, which is characterized in that a water outlet at the top of a chemical crystallization circulating granulation fluidized bed is communicated with a water inlet at the bottom of an efficient solid-liquid separation circulating granulation fluidized bed through a middle water outlet pipe, and the water treatment system further comprises a fluorine-containing raw water tank, the fluorine-containing raw water tank is communicated with a water inlet at the bottom of the chemical crystallization circulating granulation fluidized bed through a water inlet pipe with a centrifugal pump; the middle part of the chemical crystallization circulating granulation fluidized bed is also communicated with a sodium hydroxide dosing tank and / or a sodium dihydrogen phosphate dosing tank, and / or the bottom of the chemical crystallization circulating granulation fluidized bed is also communicated with a calcium chloride dosing tank; and a water inlet at the bottom of the circulating granulation fluidized bed for efficient solid-liquid separation is also communicated with a PAC (Poly Aluminum Chloride) dosing tank and / or a PAM (Polyacrylamide) dosing tank. According to the system, the processing flow is greatly simplified, and the application occasion is greatly improved.

Description

technical field [0001] The invention belongs to the field of water treatment and relates to a circulating granulation fluidized bed, in particular to a water treatment system for removing fluorine ions of different concentrations in water. Background technique [0002] Water is the source of life and is closely related to our life. Fluoride ions widely exist in nature, normal intake is beneficial to the human body, but too much or too little fluoride ions will cause great harm to the human body. Nowadays, due to the effects of the natural environment and the discharge of human factors, excessive fluorine content in natural water bodies has become an urgent problem to be solved in many areas of our country. And due to the development of my country's semiconductor and other industries, resulting in a large amount of high-concentration fluorine-containing wastewater discharge, finding a suitable way to deal with high-concentration fluorine-containing water has also become a pr...
