Further handled by cartridge filter and addition antisludging agent and reducing agent by pre-filtering early period processing unit The water crossed does further filtering and processing, can effectively remove remaining carbon dust and molecule pollutant, colloid in water in this way Pollutant enables membrane module more normally to make for a long time to can play the role of good protection to subsequent membrane module With ultrapure water advanced treatment system can keep good treatment effect for a long time, more durable.

The utility model is further arranged: the pre-filtering processing unit includes sequentially connected quartz filter and work Property carbon filter.

The suspended matter in raw water can be filtered out by quartz filter, made a return journey later again by active carbon filter Except colloid chlorine residue and COD etc. may cause dysgenic substance to reverse-osmosis membrane element.

The utility model is further arranged: the reverse osmosis treatment device includes the sequentially connected reverse osmosis dress of level-one RO It sets, high-pressure pump, second level RO reverse osmosis unit, it is dense that the level-one RO reverse osmosis unit and second level RO reverse osmosis unit are respectively connected with RO Water tank and RO water producing tank for being connect with EDI processing unit.

By early period sufficiently filtered water after high-pressure pump is pressurized enter level-one RO reverse osmosis unit and second level RO it is anti- In permeability apparatus, most salinity in water removal is gone by osmosis principle, achievees the purpose that desalination is passivated, process is anti-twice Salinity after infiltration processing in water more thorough can be removed, and desalination better effect, concentrated water after treatment passes to RO In concentrated water case, produces water and be stored in RO water producing tank.

The utility model is further arranged: being provided with the backwash tube for passing to pre-filtering processing unit on the RO concentrated water case Road.

It may be implemented the recycling of moisture in RO concentrated water case in this way, concentrate recirculation is to can be in pre-filtering processing unit Filter element be rinsed, to reduce the waste of water resource, more economize on resources.

The utility model is further arranged: the water supply device includes that sequentially connected pure water tank and variable frequency water supply are set Standby, the water outlet of the frequency-changing water supply device is equipped with polishing mixed bed.

Water can be supplied to by the moisture after previous processed by frequency-changing water supply device needs occasion to be used, by throwing The setting of light mixed bed can be used as the insurance process for dispelling the substance of salt content and influence water electric conductivity in water, it is ensured that water supply water Matter reaches production requirement.

The utility model is further arranged: UV sterilizer and accurate filter are equipped in the polishing mixed bed.

UV sterilizer can kill the microorganism in pure water, and accurate filter can be used to retain bacterium corpse in pure water, Meet design standard with the mushroom content further ensured that in water.

The utility model is further arranged: water inlet is provided on the side wall of the former pond, in the former pond side wall It is provided with vertical slot, the kickboard being connected with for closing water inlet is slid vertically in the vertical slot, is opened up on the former pond inner wall There is the through-hole being connected to vertical slot.

Through-hole setting keep vertical slot in water level and former pond in water level be consistent, in this way water inlet constantly into When water, the water level in former pond is continuously increased, and kickboard is driven constantly to move up, after water level goes up to a certain extent, kickboard closing Water inlet, so that avoiding excessive water from entering in former pond leads to the case where overflowing, in the case where raw water pool inner water is pumped water level When drop, kickboard is moved down so that water inlet reopens, and is achieved the purpose that add water in time, is avoided the rarefied feelings of raw water pool inner water Condition.

The utility model is further arranged: the vertical slot is close to the external transparent setting of side wall.

The height of water level in former pond can be observed in outside in this way, and kickboard can play mark action, more The state of current level is learnt convenient for staff.

In conclusion the utility model has the following beneficial effects:

Further by the setting of cartridge filter, and antisludging agent and reducing agent are added by branch pipe, can had in this way Effect removes remaining carbon dust and molecule pollutant, colloid pollution object in water removal, to can play well to subsequent membrane module The effect of protection enables membrane module is more permanent normally to use；And the concentrated water after reverse osmosis treatment can lead to It crosses backwash pipeline and passes to the re-using of pre-filtering processing unit, the case where realizing recycling for water resource, reduce waste.
