Abstract
A magnetizing photocatalytic compact wastewater reclamation and reuse device, comprises an integrated cabinet with which is provided an inlet pipe, an outlet pipe, and a sludge-baling hole. In said integrated cabinet a coagulating case, an ozone oxidizing case, a photocatalytic case, and a separating case separating sludge from water are provided. The coagulating case is connected with the ozone oxidizing case by an auto filter, and is provided inside with a mixing chamber for mixing gas, agent, and water together, with which the inlet pipe is connected. An ejector nozzle is provided at the outlet of the mixing chamber, and is connected with an ejector expander.

Working process of the present invention:
When waste water with suitable flow velocity, as 1 meter per second-3 meter per second, when entering gas, medicine, water mixing section 8 with pattern, continuous coagulating agent liquid medicine and the air that sucks from gas, medicine ingress pipe 9 by suction function, and make liquid medicine and air and sewage thorough mixing in gas, medicine, water mixing section 8, make gas-liquid flow form micro-bubble within it, carry out emulsion reaction, promote the diffusion of oxygen molecule and coagulating agent liquid medicine, quickened coagulation process.When the gas liquid mixture of finishing coagulation process is forced by ejector nozzle 11, the strong magnetic area that magnet ring 10 produces, can produce 4000～20000 Gausses' strong magnetic field in the water pipe, when magnetic line of force and current perpendicular quadrature, water passes through magnetic field with certain flow velocity under external force, makes cutting magnetic line movement, can produce electric charge and the electromotive force that makes charge movement in the water, so sewage has just produced physical changes such as electric current, potential difference, produce and formed electric energy.At this moment electric charge, current potential have been arranged in the sewage, the state and the character that will change water itself and be included in other material in the water, this magnetized water has just had tube wall contacted with it, wall of container to produce the energy of physical change and electrochemical change.In unpurified sewage, be dissolved with the impurity of compositions such as salt, alkali, acid to some extent, sewage has certain potential of hydrogen, undissolved solid impurity and micro-metal, non-metallic element are to some extent also suspending simultaneously, these impurity and other element impel most industrial or agricultural, life, tap water all to belong to the nonisulated material that certain conductivity is arranged, can be magnetized to some extent, foreign material such as calcium in the water and iron also can produce the ion of positively charged and negative electricity simultaneously.Ion increases suspending sundries cohesion, volume owing to plus-minus electric relation attracts each other, and finishes sewage magnetization coagulation process.
When being injected in the jet expander 12 by ejector nozzle 11, because in the jet expander 12 whole potential water, it is oval barrel-shaped design, spatial area goes out greatly more than 20 times than ejector nozzle 11, and ejector nozzle 11 is at same straight line planar concentric(al) circles with jet expander 12, ejector nozzle 11 and jet expander 12 15cm of being separated by, when ejector nozzle 11 at a high speed during the sewage directive jet expander 12 of ejection, utilized the jet energy dissipating to entrainment principle, the sewage that jet expander 12 peripheries are crossed by coagulation is sucked by jet expander 12 continuously and is magnetized, mix, form the big current of average rate, loss of momentum when directly covering of the fan sprays in water because the big momentum current of speed homogeneous have significantly reduced turbulence pump water, flow is amplified significantly, flow velocity slows down, and the bulky suspending sundries that has condensed is reduced impact.Sewage with average rate big current push in the process of strainer water inlet 14, utilize the jet energy dissipating to entrainment principle again, to advance automatic filter 13 to the bulky suspending sundries that has condensed, it by automatic filter 13 inner filtration precision 20 microns filtration, thoroughly will hold back greater than 20 microns condensation product, when differential pressure sensor or timer are felt this cleaning filter screen when in the automatic filter 13, automatic filter 13 can be realized the function of flushing automatically, filter residue is arranged to mud-water separation case 7 by filter blow-off pipe 16, again by centrifugal solid-liquid automatic segregator 25 with mud-water separation, enter sewage sludge harmlessness and handle.In the filtration that by automatic filter 13 inner filtration precision is 20 microns, after thoroughly will holding back greater than 20 microns condensation product, continue to flow into ozone oxidation case 5 less than 20 microns pollutents and sewage by strainer water outlet 15, thereby finish first step filtration procedure.
Owing to be provided with ozone air-water mixing tube 18 in the ozone oxidation case 5, ozone enters ozone air-water mixing tube 18 through 19 ejections of ozone air-water mixing nozzle through ozone gas distribution pipe inlet 17, the further strong again oxidation of remaining suspending sundries in the sewage that ozone was handled preliminary coagulation and filtration is further to BOD
5, COD, SS, NH
3Organism such as the halogenated organic matters in-N, bacterium, virus and the water, carboxylic acid, tensio-active agent, itrogenous organic substance, organophosphorus are further removed.The automatic micro-strainers 20 that the sewage of process ozone oxidation enters in the photochemical catalysis case 6 are again handled, and have finished the ozone oxidation process.
When entering automatic micro-strainer 20 through the sewage of ozone oxidation, because every group of cylinder that automatic micro-strainer 20 all is a three-decker.The end of sewage through silica gel filter residue wiper ring 20.5 is housed enters, because the other end of cylinder is equipped with pressure difference control inductor block 20.6, so sewage can only be mandatory by cylinder middle layer millipore filtration tube 20.1, greater than the colloid of 0.5-1 micron and holding back of suspended substance general, the suspended substance that water reaches less than the 0.5-1 micron flows into photochemical catalysis case 6 simultaneously in the sewage.When in the sewage during greater than the long-pending full filter cylinder of the colloid of 0.5-1 micron and suspended substance, effluent flow rate slows down, pressure increases, at this moment pressure difference control inductor block 20.6 will be transferred to the On/Off signal with each according to setting pressure scope or predefined time and organize the magnetic valve 22 that automatic micro-strainer 20 is connected, when receiving signal, finishes by magnetic valve 22 the On/Off task, when magnetic valve 22 is opened, the silica gel filter residue wiper ring 20.5 that drives the pull bar connection is walked about to magnetic valve 22 directions on prescribed stroke, and this moment, water entered mud-water separation case 7 because the hydraulic pressure reason is discharged the filter residue of holding back in every group of automatic micro-strainer 20 with silica gel filter residue wiper ring 20.5 through micro-strainer sewage draining exit 21.When the filter residue of every group being held back in the automatic micro-strainer 20 when water has washed, when receiving signal, finishes by magnetic valve 22 task of closing, drive silica gel filter residue wiper ring 20.5 homings that pull bar connects simultaneously, the on-line cleaning automatization control that in whole filter cylinder cleaning process, has realized need not to stop, thereby finished automatic micro-strainer 20 and cleaned and the sewage water micro-filter processes.
When flowing into photochemical catalysis case 6 simultaneously when sewage and less than the suspended substance of 0.5-1 micron, because load has photocatalyst film 24 on outer field gross porosity stainless (steel) wire 20.3 extexines of the inwall of photochemical catalysis case 6 and filter cylinder, at the light wave that is subjected to ultraviolet lamp socket 23.4 is under the uviolizing of 185nm-254nm, electron absorption luminous energy on its photocatalyst film 24 forbidden bands and be excited on the conduction band and produce the high reactivity electronics that has very strong negative electricity, on the forbidden band, produce the hole (h+) of positively charged simultaneously, the hole is right one by one thereby generation has very strong active electronics, semiconductor light-catalyst (TiO
2) oxidizing potential of photohole counts 3.0V with the standard hydrogen current potential, and is more high than the 1.36V of the 2.07V of ozone and chlorine, has very strong oxidisability, highly active photohole has very strong oxidation capacity, can will be adsorbed on the OH-and the H of semiconductor surface
2O carries out oxidation, generates to have strong oxidizing property OH free radical.Be that these electronics are had an effect with dissolved oxygen and water to moving to back, photocatalyst film 24 surface in the hole one by one, final hydroxyl radical free radical (OH) and the super-oxide ion with highly chemical oxidation activity that produce is from the oxidizing potential size order (F of several strong oxidizers commonly used
2＞OH＞O
3＞H

2) as can be seen the OH free radical have very high oxidizing potential, be a kind of strong oxide group, can the most organic pollutant of oxidation and the part inorganic pollutant, various bacteriums, virus killed and be carbonic acid gas and water the organism complete oxidation.Simultaneously, the electronics in the organic pollutant that is adsorbed on semiconductor surface also can be captured in hole itself, making originally not, the material of extinction is decomposed by direct oxidation, and the oxygenizement to oxide compound has broad spectrum, the electron affinity power of OH free radical can reach 569.3kj, attack the organic molecule position of high cloud density easily, further the intermediate product of oxidation forms redox system.In the light-catalyzed reaction system, these two kinds of mode of oxidizing synergies are finished more high-grade photochemical catalytic oxidation decontamination process simultaneously.On the other hand, electron acceptor(EA) can directly be accepted the high reactivity electronics of photoproduction semiconductor surface generation and be reduced, and some specific pollutants--toxic metal in the water body is as Hg
2+, Ag
1+, Cr
6+, Cu
