Use the using method of the water fluoridation of above-mentioned underground and regeneration system rapidly, comprise the following steps,
1) except fluororesin filter step, water intaking valve and product water valve are opened, upper valve, backwash valve, regeneration valve and lower valve are closed, water is entered the fluorine removing filter being filled with activated alumina in it by submersible pump work through water intaking valve, PH setting device starts, and water inlet PH is controlled at 6-7, filtered water multiparity water branch road enters water producing pipe and buffers into filtered water tank, clear water is pumped and is delivered to user after accurate filter filters by working shaft, employing activated alumina is filtrate, fluorion in planar water, activated alumina is the granular porous sorbent material of adularescent, there is bigger surface-area. but owing to activated alumina is amphiprotic substance, iso-electric point is about 9.5, can adsorpting anion when the PH value of water is less than 9.5, positively charged ion can be removed when being greater than 9.5, therefore want to remove fluorion, it is necessary to carry out when being less than 9.5, PH value is controlled at 6-7, preferably processing best results about 6.5, so entering acid adding on the pipeline of fluorine removal device at Yuan Shui, regulating PH value to be about 6.5 to improve defluorination effect. fluorion is attracted to filter material surface, generates difficult molten material, and after running for some time, activated alumina loses except fluorine ability, and the NaOH solution with 1% regenerates, and can continue to use after regeneration.
2) when in water inlet dirt blocking filtrate, when inlet outlet pressure differential increases, need to carry out backwash, namely backwash valve and upper valve are opened, lower valve, water intaking valve, regeneration valve and product water valve are closed, submersible pump work water is entered fluorine removing filter through water intaking valve, PH setting device stopping work, backwash water through upper draining branch road and discharge pipe enter neutralization water tank and through discharged. Step is just being washed after backwash, namely water intaking valve and lower valve are opened, upper valve, backwash valve, regeneration valve and product water valve are closed, water is entered fluorine removing filter through water intaking valve by submersible pump work, PH setting device stopping work, the wash water through lower draining branch road and discharge pipe enter neutralization water tank and through discharged.
3) during normal operation, fluorion is attracted to filter material surface, generates difficult molten material, and after running for some time, activated alumina loses except fluorine ability, it is necessary to regenerate by the NaOH solution of 0.75%-1%, and reaction equation is:
(AL2O3)nXF-+OH-��(AL2O3)nXOH-+F-
The PH value meta-alkalescence of draining during regeneration, can not directly enter city planting ductwork, has made a set of neutralising arrangement draining PH adjustment to be processed for draining. Specifically, reuse water pump startup, clear water is entered fluorine removing filter through regeneration pipeline, regeneration branch after adding alkali ejector and adding alkali, now, regeneration valve and upper valve are opened, and lower valve, backwash valve, water intaking valve and backwash valve are closed, on regeneration drain well, draining branch road, discharge pipe enter neutralization water tank, neutralization water pump starts, and to circulate in the way of jet adds in neutralization water tank, acid adding is until PH value reaches emission standard, and the water discharge after by neutralization opened by bleed valve.
The above is only the preferred embodiment of the present invention; it should be appreciated that for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
