Adopting the ultra-filtration membrane Main Function is the macromole solutes such as middle suspended substance, colloid, protein, microorganism, bacterium that dewater, and does not possess the effect of removing the water intermediate ion and reducing saltiness.
Ultra-filtration membrane work is simply introduced: adopting the ultra-filtration membrane Main Function is the macromole solutes such as middle suspended substance, colloid, protein, microorganism, bacterium that dewater, and does not possess the effect of removing the water intermediate ion and reducing saltiness.
Water in the water tank enters in the ultrafiltration membrane elements by the recycle pump supercharging is laggard, its current are through the film surface, under certain pressure, part water sees through film, enter the opposite side (producing the water side) of film, the macromole solutes such as the suspended substance in the water, colloid, protein, microorganism, bacterium then can't see through film, make it produce water and reach the wash water standard.The macromole solute such as suspended substance, colloid, protein, microorganism, bacterium that is trapped within the film surface is discharged from (this part water is called as dense water) under the water impact effect, traditional technique 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 technique of this patent is that its dense water cycle is back to water tank, its quantity of circulating water is about 50% of flooding quantity, the dense water yield is large, then greatly improve crossflow velocity, 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 is subject to follow-up system the product water demand of reverse osmosis is decided, (namely when follow-up system requires the supply reverse osmosis produced water, reverse osmosis unit namely need move, when follow-up system need not to supply reverse osmosis produced water, then reverse osmosis unit was in and stops water processed).
If the conditions of demand of wash water are the operation of access control reverse osmosis also, then may cause the waste of reverse osmose pure-water, increase system operation cost.Need to when not moving water processed, reverse osmosis adopt other method to make wash water.
The application's technique can satisfy above requirement, when reverse osmosis does not move, directly utilizes pre-treatment to produce water as the former water of 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 the pure water tank liquid level is too high, not simply unnecessary dense water directly to be discharged, but preferentially will be except the backwater automatic-discharging of mycoderm.With respect to directly callable concentrated water drainage being bled off, its technique is more reasonable---and kept qualified dense water, and emitted more worse except the mycoderm backwater than its dense water water quality.
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 tank water outlet 16 by 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
Enter 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 to understand is: although above-described embodiment 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 within the scope of protection of the present invention.
