9.Summary of Research Results

An environmental friendly industrial municipal system based on coal energy matching with the southern area of China is studied. The emphasis is placed on the development and examination of the elemental technologies and systems to realize the proposed new total system from the combination of them. This project was organized by Nagoya University, and was accomplished by the joint research group of Japanese and Chinese academic researchers. The following main results were obtained: 1. An efficient power generation system by pure oxygen combustion of coal is proposed, and the stable combustion was studied by the examination in the drop tube furnace. 2. A city gas production process from Refuse Derived Fuels (RDF) in the circulating fluidized bed is developed, and gas with higher heating value than 20MJ/m3 was produced by the system. 3. The lifecycle evaluation of the civil engineering structures, especially transport infrastructures, was performed to reduce the total environmental load such as the CO2 emission and energy consumption. 4. The estimation of the amount of pollutants discharge in the atmosphere and its adverse impact on environment is carried out, and an advanced future transport system using clean energy in Guangzhou metropolitan area, China was proposed. 5. The evaluation of the energy saving potential by the introduction of decentralized energy plant was performed, and the total operation technology of the central energy system and various decentralize energy plants are developed. 6. Hybrid separation techniques for complete recycling of metallic compounds composed of harmful elements, such as Ga-As scrap and Se-As scrap, were developed. 7. The process to treat the surface water containing the humic substances by adding both the polyaluminum chloride and the powdered activated carbon and filtering with the ultrafiltration membranes was developed. 8. The analytical methods for environmental monitoring and multielement determination of about 40 elements and chemical speciation of trace metals by using ICP-MS (inductively coupled plasma mass spectrometry) have been developed to evaluate the pollutants in the environment. 9. A system of Clean Development Mechanism and its influence to China is surveyed, and environmental law system and policy at Local Levels (Canton Province and Guangzhou ) are inquired.
