摘　　要：新时代随着经济高质量发展,构建人类与自然命运共同体显得尤为重要,中水作为水资源再生利用的第二选择成为缓解水源紧张和水环境生态稳定的最优方案。从中水回用的必要性、中水回用的研究现状、中水回用的处理工艺、中水回用的工业应用实例和中水回用存在的一些问题等方面展开阐述,针对国家2025年在重点地区回用水率实现35%以上,调研建筑、钢铁、电力、印染等工业用水行业,采用超滤和反渗透相结合的方式有望使回用水率达到80%以上,并且系统和建设性地提出中水回用不仅是未来城市水源供给的主力军,而且是构建资源循环、可持续发展、“零排放”节能减排和生态和谐社会的最优选择。Entering a new era,high-quality economic development should keep pace with the times with a community of natural destiny for mankind.Reclaimed water,as the second choice for water resource recycling,has been became the best choice for alleviating water shortage and maintaining water environment stability.This paper starts from the background,research status and treatment process of reclaimed water reuse,and puts forward some existing problems in combination with the application examples of reclaimed water reuse.In view of the national reuse rate of more than 35%in key areas by 2025,the use of industrial water industries such as construction,steel,electric power,printing and dyeing is investigated,and the combination of ultrafiltration and reverse osmosis is expected to make the reuse rate reach more than 80%.It is proposed constructively that the reuse of reclaimed water is not only the main force of future urban water supply,but also the best choice for building a resource recycling,sustainable development and"zero emission"ecological society.
