Carbon-based apatite filter material based water source continuous fluoride removal equipment

Abstract

The invention relates to the field of water purification, in particular to carbon-based apatite filter material based water source continuous fluoride removal equipment which comprises a tank body; awater inlet pipe and a water outlet pipe are connected to the tank body; a sodium dihydrogen phosphate adding device and a calcium chloride adding device are sequentially connected to the water inletpipe from the inlet end to the outlet end; the lower end in the tank body is provided with a water distributor; an inlet of the water distributor is communicated with the water inlet pipe downward; the position, on the water distributor, in the tank body is provided with a carbon-based apatite filter material layer; the sodium dihydrogen phosphate adding device comprises a first water tank; the first water tank is internally provided with a sodium dihydrogen phosphate solution; a first metering pump is also connected to the first water tank; the outlet end of the first metering pump is communicated with the water inlet pipe; the calcium chloride adding device comprises a second water tank; the second water tank is internally provided with a calcium chloride solution; a second metering pumpis also connected to the second water tank; and the outlet end of the second metering pump is communicated with the water inlet pipe. The carbon-based apatite filter material based water source continuous fluoride removal equipment can realize continuous use and is good in fluoride removal effect without regeneration.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a continuous defluorination equipment for water source based on carbon-based apatite filter material. Background technique [0002] The carbon-based apatite defluoridation filter material will become saturated after being used for a period of time, and the defluoridation function will be lost. It can be regenerated with sodium hydroxide or aluminum sulfate. The defluoridation equipment is large in size. There will be a large amount of sewage discharged to cause serious secondary pollution, and it needs to be shut down for regeneration, which cannot be used continuously and affects the use effect. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a continuous water source defluorination equipment based on carbon-based apatite filter material, which can realize continuous use, has a good defluori...
