As Asia is the most populous continent in the world, the contradiction between water supply and demand is increasing. Wastewater treatment and reclaimed water use are important means to solve the contradiction between supply and demand and realize the sustainability of the water management system. Based on the data collected from 48 typical countries and regions in Asia, this study evaluates the possible influential factors on wastewater treatment and reclaimed water use such as Gross Domestic Product (GDP) level, water resource availability, water withdrawn and water stress. It is identified that per capita GDP and water stress are important factors affecting wastewater treatment and reclaimed water use. Although reclaimed water use in most Asian countries is still at the early stage, the development of wastewater treatment is conducive to the development of reclaimed water. The results of this study are believed to be useful in improving water management and sustainability levels in Asian countries.
亚洲是世界上人口最多的大陆，供水量和需水量之间的矛盾日益加剧。污水处理和再生水利用是解决供需矛盾、实现水资源管理系统可持续性的重要手段。本研究基于亚洲 48 个典型国家和地区收集的数据，评估了可能影响污水处理和再生水利用的主要因素，包括国内生产总值（GDP）水平、水资源可利用量、取水量和水压力。研究发现，人均 GDP 和水压力是影响污水处理和再生水利用的重要因素。尽管大多数亚洲国家的再生水利用仍处于起步阶段，但污水处理的发展有利于再生水的发展。本研究结果有助于提高亚洲国家的水资源管理和可持续发展水平。
