The present invention has obvious advantage than traditional lime precipitation, coagulant sedimentation, absorption method：
NaOH-CaCl2Method：Waste water pH value is adjusted using NaOH, using CaCl2 as calcium salt, its solubility is big, and dissolving adds
Convenient, easy to operate, equipment investment is small, little power consumption.Meanwhile common-ion effect caused by CaCl2 effectively reduces water outlet fluorine ion
Concentration, stable outlet effect.And lime precipitation is with Ca (OH)2As calcium salt, to ensure outlet effect, it is desirable to Ca (OH)2Throw
Dosage is big, due to the CaF of production2Precipitation is wrapped in Ca (OH)2The surface of particle, it is allowed to be fully utilized, thus dosage is entered
One step increases, and water outlet pH values will adjust back.In addition, during the emulsions of Ca (OH) 2 add, molten medicine process operation difficulty is big, pipeline
Easily block, maintenance is frequent.

Thing, turbid, the depollution thing of drop, the technology of purifying water body, have take up an area less, the spy such as treating capacity is big, quick, energy consumption is low, easy care
Point, it is significantly better than traditional coagulation-settlement process.Its general principle is：Pass through flocculant（PAC、PAM）Make non magnetic outstanding in waste water
Magnetic flocculation of the float with adding utilizes magnetic-adsorption to remove the micro- floc sedimentation of magnetic, purifying water body, magnetic kind and water into the micro- floc sedimentation of magnetic
Separated from contaminants Posterior circle uses, to F-Clearance it is more much higher than traditional coagulant sedimentation.
Magnetic-coagulation technology removes F-Basic Mechanism be：
1st, nucleation：Due to adding magnetic kind, PAC, PAM in waste water, using suction-operated, make magnetic kind quick adsorption CaF2
Form CaF2Nucleus, CaF2Nucleus can accelerate CaF2Precipitation generation, under same calcium concentration conditions, it is anti-that nucleus can both reduce precipitation
The calcium concentration that should start, the sewage Funing tablet after processing can again be even lower.
2nd, suction-operated：What is generated during aluminium salt flocculation defluorination has the indefiniteness Al (OH) of very high surface area3 (am)
Substance produces Hydrogen Binding Adsorption to fluorine ion, and fluorine ion radius is small, and electronegativity is strong, and this suction type is easy to occur.Magnetic kind
With very bigger serface to CaF2Produce magnetic absorption.
3rd, ion exchange：Fluorine ion and radius hydroxy and electric charge are all close, during aluminium salt flocculation defluorination, throw
The A1 being added in water13O4 (0H) 14 7+Deng the indefiniteness Al (0H) that is formed after polycation and hydrolysis3(am) precipitate, it is therein
OH-With F-Exchange, this exchange process is carried out in the case where waiting charge condition.
4th, complex-precipitation acts on：F-Energy and Al3+Deng being formed from AlF2+、AlF2+、AlF3To AlF6 3-6 kinds of complex compounds, complexing
Settle and remove F-。
Complex ion equation is as follows：
F-+ Al3+ →AlF2+↓+ AlF2 +↓+ AlF3↓+ AlF4 -↓+ AlF5 2-↓+ AlF6 3-↓
Sial salt natural filtering material absorption method：After fluoride waste contacts with sial salt, adsorption filtration occurs for filter material surface and ion is handed over
Change double reaction, the fluorine ion in water is adsorbed on filtrate and the OH of fluorine ion and filter material surface-Ion exchanges, and passes through
The physical reaction of economic benefits and social benefits realizes the purpose of fluorine removal.
Sial salt media performance is substantially better than traditional filter material（Such as activated alumina）, possess following outstanding feature：
1st, fluorine removal capacity is high, filtrate of the loading much smaller than activated alumina with zeolite molecular sieve, you can reaches identical fluorine removal effect
Fruit, save equipment investment cost.
2nd, time of contact is short, can greatly reduce equipment volume compared to traditional filtrate.
3rd, safe, in use without any poisonous and harmful substance dissolution, water outlet is without the exceeded possibility of aluminium ion
Property.
4th, fluorine removing rate is high, and fluorine removal is thorough, and effluent characteristics are fine.
5th, water quality strong adaptability, under severe water quality situation, higher fluorine removal capacity can also be kept.Recovery time is short,
4-6 hours, management are simple.
6th, easily never there is hardened phenomenon in filtrate, and long lifespan was up to 15 years.
