The disc-type reverse osmosis device has the advantages of great flux, adoption of the open type flow channel, long service life, easiness in maintenance and difficulty in scale formation.
Description
Technical field
The utility model relates to a kind of disc-type reverse osmosis unit, is mainly used in high-concentration sewage processing, industrial type fluid purification, concentrated.
Background technology
At present, the most of city of China is with the basic mode of sanitary landfills as garbage disposal, and in one period from now on, it will be the basic mode of domestic city domestic rubbish disposal that sanitary landfills is processed.Sanitary landfills also exists many pollution problems as present modal waste disposal method, and a large amount of percolates that particularly produce in the landfill process as not dealing carefully with, can cause severe contamination to water body and soil on every side.
Percolate is a kind of high concentrated organic wastewater, and its complicated component, water quality and quantity change greatly.The source of percolate mainly contains the moisture, the moisture in the cladding material of direct precipitation, rainwash, surface irrigation, underground water, rubbish self and the generation water of refuse biochemical reaction etc.The factor that affects the percolate composition mainly contains: the hydrogeological condition of raining in component of refuse, place weather conditions, place, landfill condition and landfill time etc.This variation of water quality and quantity that has just determined percolate is large, and Changing Pattern is complicated.The content of CODcr, BOD5, ammonia nitrogen is higher, and with the prolongation of landfill time, the organic nitrogen in the rubbish is converted into inorganic nitrogen, and the ammonia nitrogen mass concentration raises.Because the CO that garbage degradation produces
2Dissolving is so that percolate is subacidity, and the environment of this slant acidity has aggravated that water-fast carbonate, metal and metal oxide thereof etc. dissolve in the rubbish, so contains the metal ion of higher concentration in the percolate, is difficult for biochemical treatment.
The difficult variability that also shows as it of percolate.The one, generation is seasonal variety, and rainy season is obviously greater than dry season.The 2nd, the seasonal variety of pollutant composition and concentration thereof.Pollutant composition and concentration in the plains region landfill yard percolate in dry and cold season are lower.The 3rd, pollutant composition and concentration thereof change with the prolongation of the landfill time limit.The materialization of buring layer each several part is all different with biological property and manner thereof, the percolate pH value of " youth " landfill yard (using in 5 years) is lower, BOD, COD, VFA, concentration of metal ions and BODs/COD are higher, the percolate pH value of " old " landfill yard (using more than 10 years) is near neutral, BODs, COD, VFA concentration and BOD/CODcr are lower, concentration of metal ions descends, but ammonia nitrogen concentration is higher.If therefore when selecting garbage leachate treatment process, adapt to the variation characteristic of percolate, because the complexity of percolate changes, therefore only have stable operation, just can process preferably it.
The high depth Biodegradability of Wastewater is poor in the industrial production, is difficult for biochemical treatment, and there is easy fouling in traditional membrane treatment process, the defectives such as film weak point in service life.
Fruit juice is purified in the industrial products, medicine is concentrated, the RO reverse osmosis membrane average life of the original usefulness of desalinization is short, easily fouling, high in cost of production defective, influent quality is required high, needs the preliminary treatment of being strict with, and changing needs whole Zhi Genghuan, and cost is high.A kind of flux of the development need of above industry is large, open type runner, life-span length, easy care, less scaling disc-type reverse osmosis unit.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of flux is large, open type runner, life-span length, easy care, less scaling disc-type reverse osmosis unit.
The purpose of this utility model is achieved in that
A kind of disc-type reverse osmosis unit, it comprises the bearing shell of tubular, be positioned at the screwed center-pole in two ends on the bearing shell axis, be applied in a plurality of membrane modules on the center-pole, flow guiding disc in order to the support membrane assembly, be installed in center-pole up and down upper platen and the pressing disc at two ends, the below of described upper platen is provided with seal disc, the top of described pressing disc is provided with the lower seal dish, there are a plurality of radially drainage channels at the center hole place of described flow guiding disc, there are a plurality of kidney-shaped water inlet tap holes at the center hole place of described flow guiding disc, and the following table of described flow guiding disc is provided with the salient point that a plurality of helixes are arranged.
Described pressing disc offers water inlet pipe, concentrate pipe downwards and sees through liquid or clear water pipe.
Compared with prior art, the beneficial effects of the utility model are:
The salient point that the utility model helix is arranged forms the open type runner, realizes full turbulence type water inlet, is easy to wash less scaling.This disc-type reverse osmosis unit has that flux is large, open type runner, life-span length, easy care, less scaling advantage.
