Embodiment 1
Beijing general hospital, produces medical treatment and life mixes comprehensive wastewater 600t/ days, and influent quality is as shown in table 1:
Table 1 embodiment of the present invention 1 influent quality data
Process technique is as follows:
Hospital's administrative building, Outpatient Building and in hospital building waste water be immediately discharged to wastewater disposal basin 1 through bilge well, obtain hospital sewage A.
Wastewater disposal basin 1 carries out Air Exposure:
Air is blasted, it is possible to allow water and air be fully contacted exchange gaseous material and remove in water in hospital sewage A
Volatile material;This process adds the dissolved oxygen in waste water simultaneously, makes microorganism in water play a role and carries out partial organic substances
Oxidation.
Hospital sewage A carries out aeration through wastewater disposal basin 1, can remove partial contamination thing while carrying out uniform water quality,
To mixed liquid B.Aeration process gas-water ratio (volume ratio) is 6:1, and hospital sewage A is HRT=30min in wastewater disposal basin 1.
Magnetic loading coagulating:
After wastewater disposal basin 1, mixed liquid B exists a large amount of suspension particulate matter simultaneously, in mixed liquid B, add nano magnetic
Planting and PAC (aluminium polychlorid) coagulant, PAC can destroy the stable state of the fine particle of this kind of suspension, and they can adsorb in nanometer
In magnetic kind, band is magnetic.It is eventually adding PAM flocculation aid, by adsorption bridging effect, magnetic kind is tied securely with indissoluble material
Close.Wherein the dosage of nano magnetic kind is the 0.04% of mixed liquid B quality, and the dosage of PAC is mixed liquid B quality
The dosage of 0.01%, PAM is the 0.00025% of mixed liquid B quality, obtains mixed liquor C, and mixed liquid B is at coagulating unit
Interior HRT=2min.
Super Magneto separate:
Utilize super magnetic separating device 3 by the sewage in mixed liquor C, mud and wadding under the conditions of magnetic field intensity 0.4~1.5T
Particulates separates, and obtains solution D, and mixed liquor C is at super Magneto separate unit HRT=30s.
Ultra-filtration and separation:
Ultrafilter membrane process in this technique, with the pressure differential of film both sides as driving force, with ultrafilter membrane as filter medium,
Under the pressure of 50kPa, when stock solution flows through film surface, the tiny micropore of many that ultrafiltration membrane surface gathers only allows water and little point
Sub-material by and become permeate, in stock solution, volume is then trapped within the feed liquor of film more than the material in film surface micropore footpath
Side, becomes concentrated solution, thus the purpose realizing the purification to stock solution, separating and concentrate.Aperture is less than 0.02 micron, only allows water
Beneficial mineral matter and trace element in molecule, water pass through, and in nature, the volume of smallest bacteria is all more than 0.02 micron, because of
This antibacterial and the colloid more much bigger than antibacterial volume, rust, float, silt, larger molecular organics etc. can be by ultrafilter membranes
It is retained down, it is achieved thereby that purification process.Process solution D through ultrafiltration system and obtain solution E.
Activated carbon filters:
Absorbent charcoal material processes through high-temperature activation and special pore-creating footpath regulation technology so that it is possessed vast specific surface
Long-pending, the pollutant in water body are adsorbed onto activated carbon surface by the effect of Van der Waals force or chemical bond, make the pollution in water body
Thing is removed.Activated carbon is that the most tiny a kind of carbon granule has the biggest surface area, and also has more tiny hole in carbon granule--
Capillary tube.This capillary tube has the strongest absorbability, owing to the surface area of carbon granule is very big, so can be with the impurity in water body
It is fully contacted.Encounter capillary tube when these impurity to be adsorbed, aseptic.Process solution E through active carbon filter, obtain molten
Liquid F.Solution E is 20m/h by the rate of filtration of active carbon filter.
ClO2Sterilization:
After above-mentioned steps processes, the polluter of wherein most all can be removed, finally through electrolysis
Produce ClO2Disinfection, mainly ClO2Cell wall is had preferable adsorptivity and through performance, can effectively aoxidize thin
Intracellular is containing the enzyme dredging base;Can be with cysteine, tryptophan and free-fat acid reaction, the synthesis of quick control bioprotein,
Permeability of the membrane is made to increase;And viral capsid proteins can be changed, cause inactivation of virus.
This process choice electrolysis NaCl method produces ClO2Aqueous solution, cardinal principle is for there occurs following reaction:
Overall reaction: 2NaCl+2H2O=2NaOH+Cl2↑+H2↑
Anode reaction: 2Cl--2e-=Cl2↑ (oxidation reaction)
Cathode reaction: 2H++2e-=H2↑ (reduction reaction)
Generally it is electrolysed ClO2Generator can work at a higher temperature, the Cl of generation2NaOH solution meeting with heat
Produce and react as follows:
Cl2+ 6NaOH=5NaCl+NaClO3+3H2O
NaClO3+2HCl→ClO2+1/2Cl2+NaCl+H2O
Finally produce ClO2Aqueous solution, is mixed to get solution G, described ClO with solution F in clear water reserviors 6 inlet pipeline2Molten
Liquid dosage is solution G mass 0.0016%, last solution G flows into clear water reserviors 6, and the liquid that carries out disinfection is the most anti-with sewage
Should, the time of staying is 30min.
Magnetic kind reclaims:
The magnetic sludge that super Magneto separate produces is transported to magnetic kind retracting device 10, by high speed centrifugation effect by nano magnetic kind
Separating with mud, the nano magnetic kind after separation returns to flocculation plant 2 and reuses.Mud takes off through filter press
Water, filtrate delivers to wastewater disposal basin 1, and mud cake is delivered to the sludge treatment equipment of specialty and carried out subsequent treatment.
Sewage disposal of hospital result:
Through above-mentioned process technique, produce water water quality as shown in table 2:
Table 2 embodiment of the present invention 1 produces water water quality data
Final clear water reserviors 6 water outlet reaches " Discharge standard of water pollutants for medical organization " (GB18466-2005) and " Beijing
Provincial standard water pollutes comprehensive discharge standard " (DB11/307-2013), can directly outer arrange.
Embodiment 2
To using technique same as in Example 1 to hospital sewage A process described in embodiment 1, difference is:
The dosage of nano magnetic kind is the 0.08% of mixed liquid B quality, and the dosage of PAC is mixed liquid B quality
0.019%, also add FeCl3, PAC and FeCl3Mass ratio be the dosage of 10:9, PAM be mixed liquid B quality
0.0005%, obtain mixed liquor C.
ClO2Sterilization:
Described ClO2Solution dosage is solution G mass 0.0032%.
Sewage disposal of hospital result:

The present invention compared with prior art has the following advantages:
(1) present invention uses super magnetic separating apparatus to separate the flocculate precipitate after catalysis oxidation, and separating effect is more
Good, efficiency is high, and the time of staying only needs 30s in a device, much smaller than the time of staying of common flocculation sediment.(2) present invention uses
Super magnetic separating apparatus replaces common flocculation sediment, and the moisture content producing mud only has about 95%, facilitates mud subsequent treatment.
(3) present invention is without adding heavy pond again after super magnetic separating apparatus, and water treatment technology floor space only has the 1/3 of common process, joint
About take up an area.(4) present invention is follow-up hyperfiltration treatment system and activated carbon adsorption are Physical and carry out water process, it is not necessary to adding again
Learn medicament, receive such environmental effects little.(5) present invention uses ClO2To water body disinfection, compared to general disinfectants
In hgher efficiency, little effect on the human body.(6) present invention selects electrolysis NaCl mode to produce ClO2Gas solution, raw material is the easiest
?.
