[Abstract]

　The purpose of this research project was conducted to investigate the amount of the greenhouse effect gases emitted from the conventional wastewater treatment facilities, conventional and new developed on-site night soil treatment facilities, combined gray and night soil treatment facilities, and pig farm wastewater treatment facilities. Through three years' research, the emission inventory of these greenhouse effect gases such as CO₂, CH₄, N₂O was determined in each facility and process. The establishment and estimation of wastewater systems for the control of the greenhouse effect gases was also discussed in this study.
