Visible Ray Utilizing Devices to treat waste-air}

The present invention, unlike the existing method of stopping the operation of the photocatalytic reactor to regenerate the deactivated photocatalyst for the purpose of the continuous operation of the visible light (VIS-) / photocatalytic reactor, waste gas to be treated containing odors and VOCs, or city Waste gas passing through two or more visible light (VIS-) / photocatalytic reactors and photocatalytic activated photocatalytic reactors that alternately supply sewage, including sewage or industrial wastewater, and the supply of air for inactivating photocatalysts, or municipal sewage or Residual load of wastewater containing industrial wastewater and inactivated photocatalysts of other photocatalytic reactors are treated by air or steam with UV or visible light (VIS-) turned on before, after or before washing in ultrasonic or non-ultrasound environment. Biomass excluding adsorption, biofilter, biofilter to treat desorbed pollutant load during regeneration Volatile organic compounds or odor sources characterized by post-processing or combinations of post-processes capable of treating oxidative treatment, absorption, combustion, plasma, electron beam, advanced oxidation process (AOP) or equivalent volatile organic compounds or odor pollutants The present invention relates to a process and apparatus as shown in FIG. 1 for treating wastewater containing atmospheric or waste gas containing urban wastewater or municipal wastewater or industrial wastewater.

By measuring the gas phase of nC ₇ H ₁₆ SO ₂ and photocatalytic activity of the photocatalytic TiO ₂ and ZnO nanoparticles oxidize nC ₇ H ₁₆ In this case, only ZnO is deactivated and TiO ₂ remains active but SO ₂ In this case, it was observed that both types of photocatalysts were deactivated, and the deactivation of the photocatalyst was suggested that the conduction pattern of the semiconductor surface was changed from N type before photocatalytic reaction to P type after deactivation due to adsorption of oxides such as water and carbon dioxide. It became. The deactivated photocatalytic nanoparticles were reported to be recovered almost intact after drying for 24 hours at 70 ° C. after distilled water washing and centrifugation in an ultrasonic environment. [Liqiang et al., Applied Catalysis A: General, 275, 49- 54, 2004]. As described above, when treating waste gas containing odors and VOCs or wastewater containing urban sewage or industrial wastewater through a photocatalytic reactor carrying a photocatalyst, which has been spotlighted as an environmental catalyst, the oxidation of pollutants over time Due to the deactivation of the photocatalyst by adsorption of intermediate derivatives, the pollutant removal capacity of the photocatalytic reactor is less than the design criteria, so the photocatalytic regeneration of the visible light (VIS-) / photocatalytic reaction process is required. The desorption source load introduced into is characterized by a fluctuating load or shock loading greater than the desorption source load in the post-process after the initial photocatalyst regeneration. Therefore, a robust design that can handle temporary fluctuating load is essential for the post process.

The following studies were carried out on the deactivation and regeneration of the three photocatalysts. Medina-Valtierra et al. [Applied Surface Science, 252, 3600-3608, 2006] investigated the regeneration of photocatalytic activity of anatase photocatalytic coatings containing Degusa P25 TiO ₂ nanoparticles that oxidize phenols in air. It was reported that the activity of all photocatalysts was regenerated when maintained at 450 ° C. for 3 hours, which was the temperature at which the photocatalyst was calcined. Vorontsov et al. [Applied Catalysis B: Environmental, 44, 25-40, 2003] reported that gaseous diethylsulfide (DES) was washed 20 times with a TiO ₂ suspension, which was deactivated by photocatalytic oxidation in a TiO ₂ deposited coil reactor. The TiO ₂ photocatalyst is either continuously irradiated with ultraviolet light until the adsorbed organic product is completely inorganic (after washing with sulfuric acid in the washed water), or 2) immediately with water (intermediate organic product in the washed water). To report regeneration. On the other hand, TiO ₂ by sulfuric acid of the photocatalyst An irreversible deactivation, described by etching, has also been reported. Cao et al. [Journal of Catalysis, 196, 253-261, 2000] observed photocatalytic oxidation of toluene using nanoscale TiO ₂ photocatalysts, which showed that 100% of the deactivated photocatalyst was heated at temperatures above 420 ° C for 2 hours. Reported that regeneration is possible. Chang et al. [Chemosphere, 58, 1071-1078] reported that N, N'-dimethylformamide (DMF) in the gaseous phase was 10% (Degussa P-25) TiO _2. The tube was coated with a slurry to observe UV / photocatalytic oxidation and the deactivation of the photocatalyst was reported. Among the various photocatalyst regeneration methods, it was reported that the regeneration effect was almost 100% when regenerating the photocatalyst deactivated with hydrogen peroxide in the ultraviolet environment.

Patent Publication No. 10-2004-0073637 is a problem in that it is impossible to treat a biological treatment system at a high concentration range of volatile organic compounds. Disclosed is a method and apparatus for selectively treating biological and photochemical treatments using only a biofilter when the concentration is lowered to a degree that can be treated with a biofilter and when the concentration is low. However, in Patent Publication No. 10-2004-0073637, it is a problem to be solved that the biological treatment system cannot be treated in the high concentration range of the volatile organic compound, and thus lowers the concentration from the high concentration range of the volatile organic compound to the bioavailable concentration. Although dilution, adsorption, absorption or other waste gas treatment methods could be selected as pretreatment processes, the motivations and objectives of presenting the photochemical methods and the synergies of hybrid systems consisting of photocatalytic reactors and biofilters were not mentioned. In Examples and Comparative Examples of Patent Publication No. 10-2004-0073637, only the performance results when only the biofilter and the biofilter consisting of a biofilter and a UV / photocatalytic reactor were operated were compared with each other. Presenting It did. Therefore, rather than claiming the hybrid system itself consisting of photocatalytic reactor and biofilter, it is a problem to solve the problem that biological treatment is impossible at high concentration range of volatile organic compounds. The invention claims a method and apparatus for selectively using biological and photochemical treatments.

When treating waste gas containing odors and VOCs or wastewater containing municipal sewage or industrial wastewater through a visible light (VIS-) / photocatalytic reactor carrying a photocatalyst, oxidation of the pollutant over time Due to the deactivation of the photocatalyst by adsorption of the intermediate derivatives, the VIS- / photocatalytic reactor's pollutant removal capacity is less than the design standard, making continuous operation of the VIS- / photocatalytic reaction process impossible. . Therefore, in order to solve this problem, a new visible light (VIS-) / photocatalytic reaction process that enables continuous operation of the visible light (VIS-) / photocatalytic reaction process is required.

On the other hand, when the deactivated photocatalyst is reversibly regenerated by air or steam with UV or visible light (VIS-) turned on before, after, or after washing in an ultrasonic environment or non-ultrasound environment, the desorbed source load is treated. There is a need for post-processing or a combination of post-processes that can handle biological treatments, absorption, combustion, plasma, AOP or equivalent desorption source loads other than adsorption, biofilters, biofilters. In addition, the combination of these visible and photocatalytic reaction processes and post-processes must be economical by generating synergy effects.

The problem solving means of the present invention can be largely classified into two cases. In the first case, the problem solving means for regenerating the inactivated photocatalyst supported or coated on the photocatalyst carrier irrespective of the adsorption capacity of the photocatalyst carrier. In the second case, the photocatalyst having a very high adsorption capacity filled in the visible light (VIS-) / photocatalytic reactor It is a problem solving means for regenerating an inactivated photocatalyst supported or coated on a carrier at a high temperature.

The first problem-solving means is that the VIS- / photocatalytic reactor cannot be operated continuously as the decontamination capacity of the VIS- / photocatalytic reactor is less than the design criteria due to the deactivation of the photocatalyst.

Adsorption to treat desorbed contaminant loads together when regenerated by non-desorbable media, biological treatments including biofilters, post-processes capable of treating absorption, combustion, plasma, AOP or equivalent volatile organic compounds or odor pollutants, or It is a hybrid system characterized by a combination of post-processes, which makes it possible to continuously and efficiently treat the wastewater containing air or waste gas containing volatile organic compounds or odor pollutants, or municipal wastewater or industrial wastewater.

A second problem solution is the supply of desorbable media, including but not limited to waste gas subject to treatment containing odors and VOCs, or sewage water containing municipal sewage or industrial wastewater, and hot steam or non-combustible gases required for inactivated photocatalyst regeneration. Two or more visible light (VIS-) / photocatalytic reactors swinging alternately, and non-combustible temperature above the boiling point of volatile organic compounds contained in sewage water including superheated steam or waste gas, or municipal sewage or industrial wastewater in the desorption medium. Deactivated photocatalysts filled with visible light (VIS-) / photocatalytic reactors containing but not limited to a desorption medium are provided with UV or visible light before, after, or before or after washing in an ultrasonic or non-ultrasound environment. Combustion or equivalent volatile organic compounds when desorbed pollutant loads are recovered when (B) a hybrid system consisting of a post-process or post-process combination capable of treating odor pollutants, which continuously treats wastewater containing atmospheric or waste gases containing volatile organic compounds or odor pollutants, or municipal sewage or industrial wastewater.
