Description
Technical field
The invention belongs to water-treatment technology field, relate to a kind of method of removing water pollutant, relate in particular to a kind of deep-purifying method of the water that is polluted by micro-content organism.
Background technology
Photocatalysis technology utilizes ultraviolet light irradiation to have the semiconductor catalyst of photocatalytic activity, as titanium dioxide (TiO
2), zinc oxide (ZnO), tungstic oxide (WO
3) etc., the valence band electronics of semiconductor catalyst is subjected to transitting to conduction band after the exciting of UV-light, generates the electronics with strong reducing power at conduction band, the hole of a strong oxidizing property then occurs in valence band.Because the hole that the ultraviolet excitation semi-conductor produces and move to semiconductor surface and captured the hydroxyl radical free radical that the back forms by water or hydroxyl and have extremely strong oxidation capacity, organic pollutant that can the oxidation overwhelming majority also makes it mineralising, for example alkane, Fatty Alcohol(C12-C14 and C12-C18), lipid acid, alkene, phenol, organic acid, aromatic hydrocarbons, dyestuff, polychlorobiphenyl, tensio-active agent, agrochemical all contaminations.
But, the activity of photocatalysts such as currently used titanium dioxide is high not enough, need to rely on ultraviolet excitation, and can not utilize the excited by visible light in the sunlight, reaction efficiency is low so the method for photocatalytic degradation pollutent exists, long shortcoming of needed time of contaminant degradation.Usually, also need to adopt ultraviolet lamp as light-catalysed light source, because long reaction time, the energy consumption height is difficult to bear on economy, and the cost of practical application is very high.In addition, the applied research of photochemical catalysis in water treatment at present all is limited to the higher situation of Pollutant levels basically, do not find a suitable applications object from light-catalysed characteristics for photocatalysis technology, and handle the water of higher Pollutant levels, required time of photocatalysis treatment is longer.In present water treatment field of attempting application, to compare with other technologies, the processing cost of photocatalysis technology is too high, does not have competitive power economically, so the application of photocatalysis technology in water treatment is subjected to great restriction.
On the other hand, the underwater micro-organic matter pollution problems is more and more outstanding, as disinfection byproduct (DBP) in the micro-natural organic matter that exists in the drinking water source and various poisonous and hazardous artificial synthetic organic materials, the tap water and the trace endocrine disrupter and the persistent organism that may exist, the insecurity that also runs into some micro quantity organic pollutants in the reusing sewage and constituted.Traditional water technology is difficult to effectively with organic matter removal micro-in the water.
Ozone oxidation-biological activated carbon technology is the method for micro quantity organic pollutant in the purifying waste water of generally adopting in the world at present, the water that promptly contains micropollutant is earlier through ozone oxidation, organism is tentatively degraded, the organism proportion that is degraded by microorganisms easily in the water improves, biodegradable improves, and then further purifies with the biological activated carbon method.Yet, because ozone and organism react stronger selectivity is arranged, promptly very fast with some substance reaction, and very slow with some substance reaction, all organism of can not degrading very effectively; In addition, in the independent ozone oxidation unit, ozone is also not ideal by the mass transfer of gas phase in water, and the ozone in the gas phase can not be dissolved in the water fully, causes the utilising efficiency of ozone not high.Consequently, in the ozone oxidation unit, organic pollutant can not well be degraded, and also influences the effect of subsequent biological treatment, causes whole ozone-BAC process desirable not to the utmost to the removal efficient of micro-content organism.
Summary of the invention
The objective of the invention is that to remove in the water organic pollutant efficient low in order to solve in the prior art photochemical catalysis, the problem that cost is high provides a kind of especially method of micro-content organism of water pollutant of effectively removing more economically.
The invention provides the method for a kind of ozone enhanced photocatalysis-biological activated carbon deep purifying water, it is characterized in that this method mainly comprises following ozone enhanced photocatalysis and two unit of biological activated carbon:
Pending water enters from the bottom of the ozone enhanced photocatalysis reactor that contains photocatalyst of placement ultraviolet lamp, and ozone gas feeds from the bottom of described reactor, and described ozone gas is through air distribution plate and water uniform mixing in the described reactor; Water and ozone gas residence time of described reactor between 1～20min, the organic pollutant in the water is removed or transforms; Flow out on top from described reactor in the water after the preliminary treatment, and ozone tail gas is discharged from the gas discharge outlet of described reactor;
Through the water of above-mentioned preliminary treatment a side inflow from the biological activated carbon reactor, the biological activated carbon layer that current are filled in reactor, the residence time, organic pollutant was by biological degradation, removal in the water between 10～80min; Water after the processing flows out from described reactor opposite side.
Dosage at the unitary ozone of ozone enhanced photocatalysis can be determined according to the water quality objective of influent quality and water outlet, between 0.5～20mg/L; Pending water is long more in the ozone enhanced photocatalysis unit and the unitary residence time of biological activated carbon, and the ozone dosage is high more, and then the effect of water treatment is good more, and the water quality of handling back water is good more, but can increase processing cost.
Photocatalyst can be titanium dioxide, zinc oxide etc., that photocatalyst can adopt suspension or fixed form, for example photocatalyst is coated on the inwall of ozone enhanced photocatalysis reactor, or be coated on the thin slice that is placed in the ozone enhanced photocatalysis reactor, perhaps photocatalyst is loaded on the small-particle.
Ultraviolet lamp is placed on the center of described ozone enhanced photocatalysis reactor, and the ultraviolet lamp outside is covered with quartz socket tube, protects.
The present invention organically combines ozone enhanced photocatalysis and biological activated carbon technology, and is applied to the deep purifying of micro-polluted water.Advantage of the present invention is: add small amount of ozone in photocatalytic process, can improve organic removal speed widely, shorten the light-catalysed treatment time greatly, / tens to 1/10th of an energy consumption of the lamp that the required energy consumption of interpolation ozone is only saved to some extent, so add a spot of ozone, greatly reduced processing cost; And ozone utilising efficiency under the effect of UV-light and catalyzer improves; Ozone enhanced photocatalysis and biological activated carbon are combined, the advantage of utilizing ozone enhanced photocatalysis to be easy to change compound structure and improving biodegradable performance, and utilize biological activated carbon technology energy economical and effective to remove the advantage of biodegradable organic, can not only remove organic pollutant efficiently, and more more economical than simple employing photochemical catalysis or ozone enhanced photocatalysis, have more economic competitiveness.So the present invention is lower than the processing cost of independent photochemical catalysis, ozone enhanced photocatalysis or photochemical catalysis-biological treatment, treatment effect is better, is a kind of method of deep purifying micro-polluted water efficiently more economically.
