Regulating reservoir:Regulating reservoir can be sufficiently mixed water quality, balanced water quality and avoid precipitating, and be conducive to subsequent handling.
Sedimentation basin:Waste water is not before coagulant and flocculant is added, itself matter of colloid and tiny suspended particulate in water
Amount is very light, and random Brownian movement is done by the collision of the molecular thermalmotion of water.Particle is all with same sex charge, between them
Electrostatic repulsion prevent it is closer to each other and aggregate into larger particle between particle;And coagulant and flocculant are sequentially added in water
Afterwards, charge neutrality occurs with the colloid of suspended matter and discrete particles, forms wadding grain sedimentation, and they collide with each other in infall process
Cohesion, size and quality constantly become larger, and settling velocity is continuously increased.Floccule body has powerful adsorption capacity, can not only adsorb suspended matter,
It can also absorbed portion bacterium and dissolved matter.Select the appropriate coagulant, such as the coagulant can be as needed
Aluminum sulfate, aluminium polychloride, poly-ferric chloride, ferrous sulfate, alum (alum), sodium aluminate or ferric sulfate;Flocculant is
Polyacrylic acid, Sodium Polyacrylate, calcium polyacrylate (CPA) or polyacrylamide;Preferably, the coagulant for PB1 gene or
Poly-ferric chloride, the flocculant are polyacrylamide PAM.Lime can make the calcium and magnesium plasma deposition in water, effectively reduce carbon
Hydrochlorate hardness.The concentration of lime is 150-200mg/L, the concentration of coagulant is 15-20mg/L, the concentration of flocculant is 0.5-
1mg/L。
Clear water reserviors:For the upper strata clear water generated in settlement on storage pond, and acid adding adjusts pH, and the acid is hydrochloric acid or sulphur
Acid.
Self-cleaning filter intercepts solid impurity and particulate matter in water using strainer, so as to reduce the turbidity of water, improves
The filter-specific equipment of water quality.Water is to enter filter interior by water inlet, and the strainer in machine blocks the impurity in water
It cuts;It, which has the function of to be filtered water and have, automatically carries out filter core cleaning blowdown.The mistake of the self-cleaning filter
It is 80 μm, 100 μm, 120 μm, 150 μm or 200 μm to filter size, can select appropriate filter sizes, such as 150 μm.By certainly
Water after cleaning filter filtering enters ultrafiltration apparatus, and the anti-sewage cleaned, which is discharged into regulating reservoir, carries out circular treatment.
Ultrafiltration is using pressure as motive force, for the purpose of macromolecular and separation of small molecuies.In ultra-filtration process, aqueous solution exists
Under pressure promotes, film surface is flowed through, less than the solvent (water) of fenestra and small molecule solute water permeable membrane, becomes scavenging solution, compares fenestra
Big solute and solute group is trapped, and is discharged with current, is become concentrate.Ultra-filtration process is dynamic filtration, and separation is to flow
It is completed under dynamic state.In the utility model, the ultrafiltration production water generated through ultrafiltration apparatus enters reverse osmosis unit, concentrate or
The backwash liquor that person is used to clean ultrafiltration apparatus is discharged into regulating reservoir and carries out circular treatment.
Reverse osmosis also known as reverse osmosis, one kind isolate the UF membrane operation of solvent using pressure differential as motive force from solution.
Pressure is applied to the feed liquid of film one side, when pressure is more than its osmotic pressure, solvent can be made reversed against the direction of naturally osmotic
Infiltration.So as to the solvent penetrated in the low-pressure side of film, i.e. penetrating fluid;The solution that high-pressure side is concentrated, i.e. concentrate.If
With reverse-osmosis treated seawater, fresh water is obtained in the low-pressure side of film, bittern is obtained in high-pressure side.
Reverse osmosis unit:Such as reverse osmosis unit can be selected as needed;Such as described device can be 5 μm of security personnel
Filter.Cartridge filter belongs to accurate filter, and operation principle is to carry out mechanical filter using the hole of 5 μm of PP filter cores.
Remaining trace suspension particle, colloid, microorganism etc., are trapped or adsorb in cartridge surface and hole in water.Security personnel's filtering
The major advantage of device is efficient, resistance is small, is conveniently replaceable.Cartridge filter is generally less than 10 μm using aperture, according to reality
Situation may be designed as 5 μm or lower.The concentrated water generated after reverse osmosis unit filters enters activated carbon reaction settling basin.According to
It needs to select appropriate reducing agent and antisludging agent, the reducing agent can be sodium pyrosulfite, sodium hydrogensulfite, the antisludging agent
Can be calgon, sodium tripolyphosphate.It needs periodically to add in fungicide in reverse osmosis unit, specially once a week,
The time is added as 2h or so, the fungicide can be bis- bromo- 3- amino propionamides (DBNPA) of 2-2-, isothiazolinone.Also
The concentration of former agent is 3-5mg/L, the concentration of antisludging agent is 3-5mg/L, the concentration of fungicide is 80-100mg/L.
Reuse pool:Sewage is recycled after serial of methods is handled, specially after reverse-osmosis treated
Production water enters reuse pool.
The course of work of the utility model:
It opens the first electrodynamic pump 101, closes the first electric valve 402, the second electric valve 403, sewage with high salinity is along inlet tube
11 enter regulating reservoir 1, and following sewage sequentially enters sedimentation basin 2, clear water reserviors 3, self-cleaning filter 4 along connecting tube 22;By
Salinity sensor 401 in self-cleaning filter 4, when less than preset value 1000mg/L, opening the first electric valve 402, next
