摘要

The present invention provides a photocatalytic reactor and a biofilter for continuously purifying and discharging air or waste gas containing volatile organic compounds or odors in a workplace or a work room including a general factory, a compost factory, etc., for improving the working environment and preserving the air environment. It relates to a process of combined hybrid system. The photocatalytic reactor carries TiO2 inside a circular or square or other shaped plastic or metal tube with corrosion resistance that connects air or waste gas containing volatile organic compounds or odors emitted to the blower from the workplace or workshop to the biofilter. The glass beads coated with a photocatalyst containing the photocatalyst were filled, and the transparent glass tubes whose ends were inserted at regular intervals in the longitudinal direction of the filled tube were inserted in the vertical or diagonal direction of the length of the filled tube, and the plurality of ultraviolet rays were placed. Insert a lamp into each glass tube placed. In addition, the photocatalytic reaction was improved by coating the photocatalyst on the inner surface of the tube in contact with air or waste gas.;On the other hand, the biofilter mainly uses organic carriers including compost, bark, and peat as a microbial carrier, and granular activated carbon or internal tires with large internal pores as a support. Chemical Engineering, 39 (5), 600-606) were charged inside the biofilter.;First, AOP (Advanced Oxidation Process), such as photocatalytic reaction, oxidizes volatile organic compounds or odor generating substances that are hardly degradable or toxic to microorganisms with OH radicals to produce small BDOC (Biologically degradable organic compounds). It is a hybrid system process that makes it easy to process microorganisms in the biofilter, which is the next process by lowering or decreasing the concentration. The second feature is the synergy effect of the hybrid system process rather than the direct contribution of the photocatalytic decomposition process to the increase in elimination capacity of volatile organic compounds in the hybrid system, which adds the photocatalytic decomposition process to the existing biofilter process. Indirect contributions created by The third feature is that if the waste gas treatment flow rate is relatively large, holes at regular intervals in the longitudinal direction of the pipe connecting the air or waste gas containing volatile organic compounds or odor emitted to the blower from the workplace or the workplace to the biofilter A transparent glass tube with a closed end to which the UV lamp is to be inserted is placed in the vertical direction of the filled tube length. Therefore, it is possible to replace the UV lamp which has reached the end of life even during the operation of the hybrid system combined with the photocatalytic reactor and the biofilter. The fourth feature is that, when the waste gas treatment flow rate is relatively large, a photocatalytic reactor uses a tube connecting air or waste gas containing volatile organic compounds or odors from the workplace to the biofilter without separately preparing a photocatalytic reactor. However, the present invention separately fabricates the process characteristics of a hybrid system comprising a photocatalytic reactor and a biofilter for continuously purifying and releasing air or waste gas containing volatile organic compounds or odors, and separately manufacturing a photocatalytic reactor when the waste gas treatment flow rate is relatively high. Instead, it includes the use of a photocatalytic reactor, a tube connecting atmospheric or waste gases containing volatile organic compounds or odors from the workplace to the biofilter.
