TAILIEUCHUNG - Estimation of methane emissions from domestic wastewater in Cau river basin by 2030

The Cau River basin has recently raised significant concerns about associated pollution issues and their critical role in socio-economic development. This study aims at assessing and forecasting the impacts of domestic wastewater on the generation of greenhouse gas emissions in Cau River basin in 2030. The main methods have been applied in this study including data collection and analysis, synthesization and inheritance method of research documents. | ESTIMATION OF METHANE EMISSIONS FROM DOMESTIC WASTEWATER IN CAU RIVER BASIN BY 2030 Cai Anh Tu 1 Le Van Quy 2 Nguyen Duc Toan 3 1 VNU University of Science Viet Nam National University Hanoi 2 Viet Nam Institute of Meteorology Hydrology and Climate Change 3 Institute of Natural Resources and Environment Training Received 8 August 2022 Accepted 30 August 2022 Abstract The Cau River basin has recently raised significant concerns about associated pollution issues and their critical role in socio-economic development. This study aims at assessing and forecasting the impacts of domestic wastewater on the generation of greenhouse gas emissions in Cau River basin in 2030. The main methods have been applied in this study including data collection and analysis synthesization and inheritance method of research documents. Moreover the study has calculated the amount of greenhouse gases from wastewater in the Cau River basin basin from the use of septic toilets other toilets and centralized wastewater treatment plant based upon the guidance of the IPCC 2006 . The results show that the CH4 gas is mainly generated from the anaerobic treatment of domestic wastewater with total CH4 emissions for the scenario up to 2030 at 234 Gg CH4 year accounting for of the total amount corresponding to 245 Gg CH4 total kg of BOD emitted when applying treatment measures. Keywords Methane gas Domestic waste Cau River basin. 1. Introduction brings negative impacts on environmental Cau River basin is one of the five longest quality and human health. rivers in Northern Viet Nam and also one of the Recent studies have identified that domestic major river basins in Viet Nam with a special wastewater treatment as potential sources of geographical position diverse and rich in artificial GHG emissions contributes climate resources as well as in the history of socio- change and air pollution 1 . Methane gas CH4 economic development among provinces is mainly generated by anaerobic .
