英文要約The demand for a large-scale treatment technology of hazardous wastewater or exhaust gas such as VOCs and dioxins is increasing in recent years. In this research investigation, the method for activated carbon regeneration using DME (dimethylether) as a solvent and the utilization of ozone produced from air as an oxidant for hydrothermal oxidation process have been examined in order to reduce the energy consumption to less than a quarter of what it used to be. (1) Survey of artificial wastewater: 1,4-Dioxane was selected for a model pollutant because of a strong need of our customers. Phenol was also selected for a model pollutant, because its notified amount of emission is one of the largest in Class 1 specified chemical substances of PRTR rule and it is inexpensive and easily available. Accordingly, we have decided to conduct future experiments using the artificial wastewater containing two kinds of chemical substances, 1,4-dioxane or phenol.(2) Investigation of the energy consumption required for the treatment of refractory organic substances by existing techniques: Advanced oxidation process (AOP) is a process for the decomposition of objective substances using a strong oxidizing power produced by combination of ozonation, hydrogen peroxide, UV, etc., which allows for a complete decomposition and harmlessness of refractory organic substances. Fenton-hydrothermal oxidation technique is also a sort of AOPs by which perfect decomposition and harmlessness of refractory organic substances are possible and we are planning to conjugate this technique with the technique of J-TOP Corporation in this project. The energy consumption required for the treatment of 1 m3 wastewater by existing AOP techniques has been investigated. (3) Investigation of a compact liquid-DME machine: We went to Nagoya University that possessed the dewatering technique with DME and examined the experimental methods and machines used there. A flowchart diagram was prepared to experimentally produce a compact liquid-DME machine for the preliminary experiment of condensation and volume reduction of pollutant and the energy consumption required for this machine was estimated.(4) Examination of an inexpensive alternative oxidant: We examined the issues of data collection in corporation with Osaka City University and decided them to be an ozone dose (0-12 g/h), reaction temperature (25-200℃), reaction pressure (1-10 MPa), and catalyst. The method to reduce the energy consumption required for the treatment of pollutant was explored and a flowchart diagram was prepared.
