It can be seen that the main distinction of single polycrystalline wastewater treatment process is two o'clock: 1, since concentrated base discharges in monocrystalline production technology
Amount must be collected separately greatly and is added to neutralizing water tank (the fluorine-containing collecting tank of low concentration) with drip valve, polycrystalline production technology concentrated base row
High-volume the small neutralizing water tank that can be directly discharged to is without causing big impact.2, polycrystalline production technology concentrated acid discharge amount greatly merely with
Drip valve discharge can still cause big impact load therefore to have to be introduced separately into reactive tank processing.And after sinking at the beginning of this reactive tank
Calcium fluoride sludge since calcium chloride is launched general insufficient and launches alkali process problem of non-uniform and leads to calcium fluoride sludge leachate
It is hazardous waste that pH value and the exceeded fluorine-containing sludge of inorganic fluoride (not including calcirm-fluoride) content, which have certain risk,.
As the changeable demand of workshop list polycrystalline of developping production of industry is more and more.Increase at battery production end corresponding
Etching device after, the adaptability of wastewater treatment is next to consider the problems of.It is how real in the case where investing least situation
The now seamless switching of single polycrystalline waste treatment capacity.
In addition, the medical fluid of calcium ion is generally provided by calcium chloride solution in sewage treatment facility design, 100 grams of water are 0
59.5 grams of calcium chloride, 159 grams can be dissolved respectively at degrees Celsius 100 degrees Celsius.It can be defeated by enough calcium ions by aqueous solution
It is sent in reactive tank.Simultaneously in order to which calcium ion preferably precipitates, reinfusate alkali reacts in reactive tank.It is useless in actual polycrystalline
In water treatment procedure, it is first passed through spent acid to be processed, liquid alkaline is then first added, reconciles to neutrality, adds while liquid alkaline is added
Entering calcium chloride solution, liquid alkaline dosage is generally entered directly into reactive tank by liquid alkaline groove tank car greatly, therefore in actual process,
Have a following drawback: liquid alkaline input is excessively rapid, and reaction acutely can be by acid mist transpiration to causing air secondary to pollute in the air.It is fast simultaneously
It is very big in zone of reasonableness difficulty that the reaction of speed also allows pH to guarantee；In addition, addition calcium chloride process lacks the judgement of dosage, add few
F is caused to precipitate the inadequate fluorine-containing height of sludge leachate, flow need to be opened big waste medical fluid by increasing.

The calcium ion of position time input reactive tank is more, and can save the medicament expense of processing.Make sludge after processing can from original
The hazardous waste of energy is changed to determining general harmful waste.Recognize that liquid alkaline provides OH-ion calcium chloride and provides calcium ion, this
Apply for that proposition replaces two kinds of medicaments with calcium hydroxide (lime), since lime is slightly soluble in water, if using lime aqueous solution as medicine
Agent, the effective dose wretched insufficiency of unit dose.Consideration is directly inputted in reaction tank with lime powder, and transporting for lime powder can
To be carried out by diaphragm pump or special powder conveying equipment.In an experiment due to diaphragm pump in transport process high failure rate,
And it is abandoned first to powder requirement is excessively high.And the big maintenance of powder conveying equipment investment is at high cost and fugitive dust is too big, scheme
Fail to implement.Finally design determines, builds a pharmacy slot, i.e., uses as lime dissolving tank 8, and stirring is arranged in pharmacy slot
Axis, has diaphragm pump to be connected to the first collecting tank 1 from groove body, i.e., is to use as reactive fluorochemical slot II at this time, while on groove body
Driving is arranged in side, upper around groove body facility to do full encirclement structure with color steel.In use, it is first water distribution in slot, will fills
There is the jumbo bag of lime powder to be promoted with driving to groove body to put into above groove body, jumbo bag is then cut open into medicament by worker and is smoothly thrown
Enter in slot, stirring is always maintained in slot, forms lime suspension, reactive tank is input to by diaphragm pump.And additional coloured silk
Steel plate can limit the flue dust that lime generates in launch process in the room, avoid the influence to surrounding enviroment.Test feelings
Condition shows that lime suspension can enter reactive tank by flow rate adjustable, and heat release caused by avoiding flow big raises acid mist, and can
To complete to fill at the right time.Filling switch is in neutrality by pH meter control until reaction liquid, both ensure that pH at this time
Normally, while calcium ion is slightly excessive, meets the leachate requirement of filters pressing mud extraction.Lime is cheap to be greatly saved facility fortune
Row expense.
