The mouth of a river, the water inlet of the delivery port connection cartridge filter 7 of the regeneration Na-ion exchanger, the water outlet of the cartridge filter
Mouth connects the water inlet of RO film filters 9, the delivery port connection production pond 10 of the RO film filters through high-pressure pump 8.
Wherein, be provided with liquid level gauge in the regulating reservoir, buffer pool and production pond, including high pressure water level liquid level gauge 12 and
Low water level liquid level gauge 13.
Wherein, two double water pumps 14 in parallel are provided with the production pond to share one with draining, two water pumps and go out
Water pipe.
Wherein, two are set in the water lines between the delivery port of the buffer pool and the water inlet for regenerating Na-ion exchanger
Conveying pump 11 in parallel.
Wherein, the air floatation machine connection dissolved air floatation pump 21, the air floatation machine has sludge outlet.
It should be noted that in the utility model, the air floatation machine uses dissolved gas floatator, and sky is sent by air compressor
Gas, it is forced to be dissolved in water under 0.35Mpa pressure, forms dissolved air water.In the case of unexpected release, it is dissolved in water
Air separates out, and forms substantial amounts of microbubble group, and the suspension in sewage that is coming with pumping and being flocculated after dosing fills
Tap is touched, and absorption in the suspension that wadding has collected, makes its density decline floating to the water surface, reached in slow uphill process
Except SS and CODcr purpose.The scum silica frost on air floatation machine surface can be collected into scum pipe by Slag Scraping Device, then flow into sludge-tank
In.Pre-treatment is carried out to waste water using air floatation machine, the suspension and CODcr in waste water can be effectively removed, be handled for follow-up equipment
Mitigate processing load, can specifically use the AFSF series supers air-dissolving air-float of Zhucheng Ao Feng environmental protection equipments Co., Ltd production dirty
Water treatment machine.
The multi-functional filter can further remove suspension, particulate matter in water removal, reduce turbidity, purify water, subtract
Few system dirt, bacterium algae, corrosion etc. are produced, and to purify water and protect system other equipment normal work, water is entered by water inlet
Enter multi-functional filter, after impurity deposits, discharge dirt, discharging pollution.Multi-functional mistake disclosed in CN2003201253565 can specifically be used
Filter is realized.
The valveless water filter device is periodically backwashed using siphon principle, filter water inlet water outlet, flushing and draining
Valve is not had to, by hydraulic action automatic running.Raw water passes through the top-down mistake of filtering layer by water pipe into valveless water filter device
Filter, afterwards into water tank, enters next stage after being full of by outlet pipe.Filtering layer constantly stays suspension, causes resistance to increase, and
The water level in siphon pipe is promoted constantly to raise, when water level reaches the auxiliary siphon tube mouth of pipe, water is fallen from the pipe, passes through exhaust tube
Air so as to taking away siphon decline, when vacuum reaches certain value, siphonage just occurs and water is passed through from bottom to top
Filtering layer backwashes to filtrate.When the flush box water surface drops to siphon destructing tube, air enters siphon pipe, destroys siphon
Effect, backwash terminates, and filtering restarts, specifically using full automatic high efficiency fibre bundle disclosed in CN2011104486439 without
Valve filter.
Described regeneration Na-ion exchanger is used to remove calcium ion, magnesium ion in water removal, produces the ion exchange of softened water
Device.Ion exchange resin in composition water in the calcium of hardness, magnesium ion and demineralizer swaps, calcium, magnesium ion quilt in water
Sodium ion exchange, make to be not easy to form carbonate scale and sulfate scale in water, so as to obtain softened water.Reduce the content of hardness in water
Follow-up equipment is set to reduce the risk of internal incrustation, the specific regeneration sodium for using segmental structure using cylinder disclosed in CN87211270
Ion-exchanger.
The cartridge filter, inside use one kind of the tubuloses such as PP melt-blowns, line burning, folding, titanium filter core, active carbon filter core
Filter core is handled it as filter element, raw water by cartridge filter, is further remained in removal unboiled water mechanical miscellaneous
Matter.Its feature is：1) filtering accuracy is high, filter core uniform pore diameter；2) filtration resistance is small, and flux is big, retaining power is strong, service life
It is long；3) material for core cleanliness factor is high, pollution-free to filter medium；4) chemical solvent such as acid and alkali resistance；5) intensity is big, high temperature resistant, filter
Core is unlikely to deform；6) cheap, operating cost is low, is readily cleaned, replaceable filter element.It can specifically use
The cartridge filter of continuously-running disclosed in CN201220606347.7.
First, waste water enters in air floatation machine and handled, and waste water contains more tiny micro- life after the processing of preceding system in water
Thing and suspension, these microorganisms can be attached on the filler of follow-up system and breed, and block filler and then influence follow-up equipment
Service life and removal efficiency, therefore first pass through air floatation machine and go most of tiny microorganism in water removal, and it is outstanding to remove part
Float, reduce the CODcr and turbidity of waste water.
Secondly, waste water can further reduce the suspension and turbidity in water by valveless water filter device and multi-functional filter
Value, to meet the inflow requirement of follow-up equipment.Valveless water filter device is prepared using siphon principle, does not set valve on the filter
Door, automatic running and cleaning can be achieved, reduce the risk slipped up by manual operation.
Finally, using RO film filters as desalter, it is a kind of using pressure differential as motive force, is separated from solution
Go out the UF membrane operating process of solvent.Have the characteristics that desalting efficiency is high, the rate of recovery is high, service life is long, effluent quality reaches
Reuse standard, carries out reuse, and RO film filters directly can commercially purchase corresponding RO film filters to realize.
During work, RO concentrated waters and recirculated water draining initially enter regulating reservoir, then are entered by lifting water pump in air floatation machine,
The microorganism for going in water removal to remain by air floatation machine；Again by valveless water filter device and multi-functional filter, remove surplus in waste water
Remaining suspension and colloidal substance etc., suspension, colloidal substance are emitted by the backwash of equipment；Through valveless water filter device and more work(
Composite waste after energy filter filtering can effectively remove mixing by regeneration Na-ion exchanger, regeneration Na-ion exchanger
Calcium, magnesium ion in waste water, the hardness in waste water is reduced to ensure that low-pressure boiler is less scaling；Waste water is again by security personnel's filtering
Device, the effect of cartridge filter is that the less suspension of particle diameter ensures that the water quality index of waste water meets to enter subsequently in water removal
The requirement of membranous system, enter finally into RO film filters level into RO membranous systems in, UF membrane act on decline waste water in salt
Point.70% or so, production water reaches reuse standard, carries out reuse for final producing water ratio control.
This practicality initially enters regulating reservoir with the new waste water by after processing, ensures that follow-up equipment system can be steady
Flow under run, while also ensure that water quality does not have bigger fluctuation.
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as the scope of protection of the utility model.
