摘　　要：为全面了解河南省工业用水重复利用情况,提出一种基于用水统计的工业用水重复利用率测算方法,通过河南省全口径用水量数据和典型企业水重复利用数据,测算河南省工业用水重复利用率,并对测算成果进行分析。结果表明:河南省2022年工业用水重复利用率为94.15%,各市在82.89%~96.76%,各行业在23.89%~98.04%;河南省工业用水重复利用整体水平较高,城市之间差异显著,纺织、食品和其他行业水平较低,火电行业对河南省工业用水重复利用率的影响程度最高;全省提高工业用水重复利用率的节水潜力为7.97亿m^(3),工业节水潜力较为可观。采用的测算方法适用于区域工业用水重复利用率测算,测算成果符合河南省实际,可为河南省加强工业节水管理、提高工业用水效率提供参考。The industrial water recycling rate is an important index to reflect industrial water use efficiency,industrial water saving degree, and to evaluate industrial water recycling. To comprehensively comprehend the recycling situation, the calculation and analysis of the recycling rate of industrial water is helpful. It is of great significance to predict the potential of industrial water saving, improve the level of industrial water saving and promote the sustainable development of industry. Currently, the research on industrial water recycling rate mainly focuses on the calculation of enterprise water recycling rate and the utilization of industrial water recycling rate, but lacks the research on the calculation method of regional water recycling rate. The statistical survey currently analyzes the water use in our country has basically achieved the comprehensive coverage of self-provided water source industrial enterprises and improved the quality of industrial water data. Based on this, the calculation of industrial water recycling rate will be more reasonable and reliable.A calculation method of the recycling rate of regional industrial water was proposed based on the water use statistics survey in Henan Province. The industrial water consumption of various industries in each city was obtained by classifying and calculating the water consumption of different sources. The quantity of recycled water of different industries in each city was calculated according to the recycling rate of various industries using typical enterprises. Finally, the industrial water recycling rate of each city and Henan Province was calculated. The results were then analyzed from the aspects of industry level, spatial distribution, sensitivity and water-saving potential. Kmeans clustering method was used to analyze the spatial distribution characteristics of industrial water recycling rate in Henan Province. The influence of each industry on the industrial water recycling rate in Henan Province was studied by single factor sensitivity ana
