Abstract

Urban population, it is predicted that, will reach at 5 billion by 2030 and 95% of urban expansion in the next decades will take place in developing countries. In addition, it is indicated that rapid urbanization brings pressures on freshwater supply and sewage treatment. Then sustainable development goal 6 shows 8 targets to ensure availability and sustainable management of water and sanitation for all, and intends to increase proportion of population using safely managed sanitation services, wastewater safely treated and bodies of water with good ambient water quality. Bangkok, which is the capital of Thailand, has 8 centralized sewage treatment plants (CSTP) designed to treat domestic wastewater of approximately a half of residents. However, water quality of some canals in the area provided with sewage works (APSW) has not been improved well, and the cause is not found out due to uncertainty of flows of domestic wastewater. Thus, this study has identified flows of domestic wastewater by an inventory approach to estimate volume of wastewater and biochemical oxygen demand (BOD) discharge based on population distribution in Bangkok. As the results, it is estimated that 75% of BOD discharged in APSW does not reach CSTP.

使用泰国曼谷污水清单进行生活污水处理的水量和BOD流量分析

据预测，到2030年，城市人口将达到50亿，未来几十年95%的城市扩张将发生在发展中国家。此外，快速城市化给淡水供应和污水处理带来了压力。然后，可持续发展目标6提出了8项具体目标，以确保所有人都能获得水和卫生设施并对其进行可持续管理，并打算提高使用安全管理的卫生设施服务、安全处理的废水和环境水质良好的水体的人口比例。曼谷是泰国的首都，有8个集中污水处理厂(CSTP)，用于处理大约一半居民的生活污水。然而，由于生活污水流量的不确定性，在有污水处理厂的地区，一些运河的水质并没有得到很好的改善，原因不明。因此，本研究根据曼谷的人口分布，通过清查方法估算废水量和生化需氧量(BOD)排放量，确定了生活废水的流量。结果表明，APSW中75%的BOD排放未达到CSTP标准。

期刊介绍： The Journal of Water and Environment Technology is an Open Access, fully peer-reviewed international journal for all aspects of the science, technology and management of water and the environment. The journal’s articles are clearly placed in a broader context to be relevant and interesting to our global audience of researchers, engineers, water technologists, and policy makers. JWET is the official journal of the Japan Society on Water Environment (JSWE) published in English, and welcomes submissions that take basic, applied or modeling approaches to the interesting issues facing the field. Topics can include, but are not limited to: water environment, soil and groundwater, drinking water, biological treatment, physicochemical treatment, sludge and solid waste, toxicity, public health and risk assessment, test and analytical methods, environmental education and other issues. JWET also welcomes seminal studies that help lay the foundations for future research in the field. JWET is committed to an ethical, fair and rapid peer-review process. It is published six times per year. It has two article types: Original Articles and Review Articles.
