HCO
3 -+ Ca
2+→ CaCO
3↓ (calcium hydroxide is excessive)
After abundant reaction, the precipitation of calcium carbonate of generation and contamination precipitation sink to bottom staving 1 under gravity, for carbonate is after treatment by the rare milk of lime mixed solution got rid of in advance in staving 1.
Liming outlet 8, for rare milk of lime mixed solution after process is discharged stand-by or be directly connected with the water inlet pipe in lime system participate in next step lime system in.
Discharge of wastewater mouth 9, for regularly discharging the precipitation of calcium carbonate and contamination precipitation that are accumulated in bottom staving 1.
Be more than the basic element of character of dilution water pretreatment unit of the present invention, but, in order to optimize the present invention, in preferred embodiments, next or several associated components can also be configured to.
In order to better control the amount adding liquid in staving 1, described staving 1 is also provided with liquidometer and detects mouth 10, liquidometer is arranged on staving 1 by anchor, and with liquidometer, to detect mouth 10 position corresponding, for detecting the height of liquid in staving 1, described liquidometer can select called putting-into-type liquid level meter or ultrasonic level gage, preferred ultrasonic level gage, its precision is high, install and easy to use.
Described staving is also provided with acid-adding port 11, for to acid adding in staving 1, because carbonate deposit is the most easily dissolved in diluted acid, common are mineral acid and organic acid all can be dissolved, the most frequently used as dilute hydrochloric acid, can regularly be got rid of by the calcium carbonate hard scale at the bottom of sinking to barrel, the waste water after cleaning is discharged from discharge of wastewater mouth 9.
Described staving 1 is also provided with overflow port 7, and described overflow port 7 is apart from staving 1 distance from top within 5cm, and overflow port 7 is controlled by coupled surplus valve, for level pressure overflow, and the safe operation of securing system.
Above-mentioned dilution water pretreatment unit is adopted to carry out pretreated method to dilution water as follows:
Dilution water and milk of lime strong solution are pumped in staving 1 from dilution water entrance 5 and lime inlet 6 according to setting ratio respectively, be configured to liming dilute solution, in described liming dilute solution, the weight percent of lime is 1%-4%, charging rear stirrer 2 is with the rotating speed rapid stirring 10 ~ 15 minutes of 110 ~ 150rpm/min, the a small amount of carbonate in dilution water and the calcium ion in milk of lime is made fully to react generation calcium carbonate, impurity particle small in liming flocculates into oarse-grained contamination precipitation thing, more than 30 minutes are left standstill after stirring completes, calcium carbonate and impurity particle is made to sink to bottom staving 1 under gravity, with the rotating speed low rate mixing of 60 ~ 85rpm/min during discharging, the liming dilute solution on top is stirred from liming outlet 8 and discharge.
