Adopting ultra-filtration membrane mainly to act on is the macromole solutes such as middle suspended substance, colloid, protein, mikrobe, bacterium that dewater, and does not possess the effect of removing the water intermediate ion and reducing saltiness.
Ultra-filtration membrane work brief account: adopting ultra-filtration membrane mainly to act on is the macromole solutes such as middle suspended substance, colloid, protein, mikrobe, bacterium that dewater, and does not possess the effect of removing the water intermediate ion and reducing saltiness.
Water in the water tank is gone in the ultra-filtration membrane element through the recycle pump supercharging is laggard; Its current are through the film surface; Under certain pressure, a part of water sees through film, gets into the opposite side (producing the water side) of film; Macromole solutes such as the suspended substance in the water, colloid, protein, mikrobe, bacterium then can't see through film, make it produce water and reach the wash water standard.Be trapped within macromole solutes such as the surperficial suspended substance of film, colloid, protein, mikrobe, bacterium and under the water impact effect, be discharged from (this portion water is called as dense water); Traditional technology is generally directly discharged dense water; Must take into account the utilization ratio of water therebetween and control concentrated water drainage high-volume, for example controlling quantity discharged is about 25-5% of flooding quantity.The technology of this patent is that its dense water cycle is back to water tank, and its quantity of circulating water is about 50% of a flooding quantity, and the dense water yield is big; Then improve crossflow velocity greatly; Raising reduces the accumulation of face dirt to the developing result of face trapped substance, reduces the obstruction of film; Improve the stability of film work, prolong the work-ing life of film.
When water tank 4 was in high liquid level, the water in the water tank 4 or the dense water of ultra-filtration equipment 7 were discharged through the water port 17 on high-position overflow trough 5 tops.
Can find out from above steering logic Fig. 3 and 4:
Reverse osmosis concentrated water is along with the operation of reverse osmosis unit produces; The operation of reverse osmosis unit receives follow-up system to the product water demand of r-o-and decide; (promptly when follow-up system requires the supply reverse osmosis produced water; Reverse osmosis unit promptly need move, and when follow-up system need not to supply reverse osmosis produced water, then reverse osmosis unit was in and stops to make water).
If the conditions of demand of wash water also add the operation of controlling r-o-, then possibly cause the waste of reverse osmose pure-water, increase system operation cost.Need, r-o-not adopt other method to make wash water when not moving system water.
The application's technology can satisfy above requirement, when r-o-does not move, directly utilizes pre-treatment to produce the former water of water as wash water.
Can find out from above steering logic Fig. 5-8: when the defective or mixing water of reverse osmosis concentrated water is defective, then directly with concentrated water discharge; When reverse osmosis concentrated water was qualified, dense water was recovered.If pure water case liquid level is too high, not simply unnecessary dense water directly to be discharged, but preferentially will discharge automatically except that the backwater of mycoderm.With respect to directly callable concentrated water drainage being bled off, its technology is more reasonable---kept qualified dense water, and emitted than its dense water water quality poorer remove the mycoderm backwater.
It is tapered that high-position overflow trough 5 bottoms become, and there is water outlet 15 in bottom centre, and the mounting height of this water outlet 15 is on refluxing opening 16 central horizontal of water tank 4.Be connected with pure water case water outlet 16 through the water outlet 15 of outlet conduit with high-position overflow trough 5, water is flowed through this pipeline by the water outlet 15 of high-position overflow trough 5
Go into water tank 4.
One water port 17 is arranged on high-position overflow trough 5 upper portion side wall; These water port 17 central horizontal are identical with the level height of water tank 4 the highest control water levels; When water tank 4 liquid levels reached this level height, water can be automatically flows out from water port 17, guaranteed that the water level of water tank 4 is the highest can only maintain this elevation of water surface.
What need understand is: though the foregoing description is to the mentality of designing of the present invention detailed text description of contrasting; But these text descriptions; Just the simple text of mentality of designing of the present invention is described; Rather than to the restriction of mentality of designing of the present invention, any combination, increase or modification that does not exceed mentality of designing of the present invention all falls in protection scope of the present invention.
