Description

The high-recovery ultrafiltration apparatus
Technical field
The utility model relates to a kind of water treatment facilities of ultrafiltrationmembrane process, particularly a kind of high-recovery ultrafiltration apparatus.
Background technology
Ultra-filtration filters be a kind of be promotion with pressure, the physical filtering mode held back by film for the basis, the beginning of the nineties, hyperfiltration technique was widely used in mineral water production, and hyperfiltration technique prepares in counter-infiltration and does preliminary treatment in pure water and the ultra-pure water system and terminal processes has also replaced traditional pretreatment mode gradually in recent years.
Ultrafiltration apparatus adopts the membrane component of doughnut structure, and membrane component can adopt hydrophilic polysulfones, polyether sulfone, Kynoar materials such as (PVDF), and pore size filter is between 0.002~0.1 μ m, and molecular cut off is 100,000 Dalton.Ultrafiltration can be removed the colloid of suspension, colloid, microorganism, larger molecular organics and various silicon, iron and aluminium in the water, stable effluent quality, precision height, turbidity≤1NTU, SDI≤3.
The ultrafiltration effect of removing water-borne glue body material, particle, bacterium, virus and protozoan etc. that is in operation is very remarkable, but also can cause the enrichment of above-mentioned substance simultaneously on the film surface, therefore carry out backwash after milipore filter must move 30-60 minute and dash soon, this just causes the pollution and the waste of water, consumption at part water accounts for about 10% of the water yield, and promptly the system recoveries rate is about 90%.Wherein content of material such as the colloid in backwash and the fast bath, particle, microorganism are higher, can't realize utilizing in traditional technology again.Given this utility model can realize the utilization to this part high-concentration waste water, and the ultrafiltration system rate of recovery is brought up to 99%, produces the water quality and satisfies SDI 5MIN≤ 3; The quality requirements of turbidity≤0.5NTU.Thereby further saved the water source, reduced the discharging of waste water, this is very far-reaching in the operating meaning of industry.
The utility model content
Main purpose of the present utility model is to carry out technological improvement on the basis of existing ultrafiltration system, realizes improving the utilization rate of water, reduces production costs simultaneously, economizes on resources.
In order to realize above purpose, a kind of high-recovery ultrafiltration apparatus is provided, it mainly comprises unit such as ultrafiltration water pump, ultra filtration unit, clarifier, ultrafiltration muddy water pump, security personnel's filter and muddy water ultrafiltration.The ultrafiltration water pump links to each other with the water inlet of this ultra filtration unit in the device; One end of water purifier links to each other with the outlet of the backwash water of this ultra filtration unit, and the other end links to each other with the import of ultrafiltration muddy water pump; Described ultrafiltration muddy water delivery side of pump links to each other with the import of security personnel's filter, and the outlet of security personnel's filter links to each other with this muddy water ultra filtration unit.
The principal character of the utility model high-recovery ultrafiltration apparatus be can the various ultrafiltration of reuse backwash and fast dashing wait waste water, can improve the rate of recovery of ultrafiltration system comprehensively.
The utility model patented technology waits wastewater collection in the middle of water purifier the backwash and fast the dashing of ultrafiltration, water purifier can carry out purified treatment fast and efficiently, can rapidly the turbidity in the waste water be dropped to about 10NTU by 300NTU, the hydraulic detention time of this equipment is about 30 minutes.This equipment can effectively improve the operating flux and the cycle of operation of muddy water ultrafiltration.
Preferably the ensure public security filter core precision 20-200 μ m of filter of the utility model.The function of this security personnel's filter mainly is to remove small particle, prevents that the milipore filter surface is scratched.If select the high accuracy filter core, the replacing of filter core will be too frequent; If select low precision filter core, will descend to the protective effect of milipore filter.Therefore take all factors into consideration from practical economic angle, select 100 μ m precision filter cores for use.
The film number proportioning of the utility model ultra filtration unit and muddy water ultra filtration unit is that 6:1 is between the 10:1.Under this kind ratio, the water inlet that becomes the muddy water ultrafiltration that the backwash water that ultra filtration unit produces can be continuous, system just can the continous-stable operation.
The beneficial effects of the utility model are: collect and purify hyperfiltration reverse-rinsing water by water purifier is set in the ultrafiltration apparatus of forming at raw water pump, ultrafiltration apparatus and product water tank, hyperfiltration reverse-rinsing water after the purification enters remaining muddy water particle in security personnel's filter interception water through the ultrafiltration muddy water pump, enter the muddy water ultrafiltration afterwards, it is as follows that muddy water ultrafiltration product water can reach water quality index:
SDI 5MIN≤ 3; Turbidity≤0.5NTU.
This water quality is suitable with ultrafiltration product water water quality, can be used for the water inlet condition of reuse or reverse osmosis unit fully.
Facts have proved, guaranteeing to produce water quality in above-mentioned qualified indication range under the identical water inlet condition, can make the ultrafiltration system water use efficiency improve about 8%, the rate of recovery that is about to ultrafiltration system brings up to 99% by about 90%, saved water resource greatly, reduction by a relatively large margin production cost.
The utility model is mainly used in the middle of large-scale industrial water supply and the reusing sewage project, can effectively improve the rate of recovery of ultrafiltration system.The raising of commercial plant water use efficiency, the reduction of operating cost, the decline of the external water amount of blowdown of system have been realized.
