| 摘 要： | 研究系统分析了黄河流域9个省(自治区)及68个主要城市的水资源状况、供水用水状况、污水处理与再生利用状况及再生水利用潜力。2020年,黄河流域68个主要城市再生水利用总量为18.1亿m3,预计未来年利用量仍有22.0亿~25.9亿m3的增长空间。黄河流域不同城市再生水利用量和利用率存在明显差异。黄河上游11个城市的再生水利用率在25%以下;中下游20个城市的再生水利用率在30%以下,低于国家规划目标。对于黄河上游兰州、包头等城市,中下游榆林、太原、济源和泰安等城市,需进一步加快推进污水资源化利用,提高再生水利用率。今后需进一步拓展再生水利用途径,特别是提高工业利用水平,加强再生水配置利用规划、再生水利用分类统计等工作。

ANALYSIS OF WATER REUSE SITUATIONS AND POTENTIALS IN MAIN CITIES IN THE YELLOW RIVER BASIN |
| |
| Abstract: | The water resources, water supply and usage, sewage treatment and reuse, and water reuse potential in 9 provinces (autonomous regions) and 68 selected cities in the Yellow River basin were systematically analyzed. In 2020, the total amount of reclaimed water used by the 68 selected cities in the Yellow River basin was 1.81 billion m3, and it was estimated that there was a potential growth of 2.20~2.59 billion m3 per year in the future. There were significant differences in the quantity and rate of reclaimed water use among the selected cities in the Yellow River basin. The water reuse rate of 11 upstream cities was less than 25%, and of 20 middle and downstream cities was less than 30%, which was below the national planning target. It was necessary to further develop the reclaimed water use for cities, such as Lanzhou and Baotou in the upper reaches of the Yellow River, Yulin, Taiyuan, Jiyuan, and Tai'an in the middle and lower reaches. In the future, it's necessary to further expand water reuse in terms of applications, especially in industrial use. Also, it is required to enhance the planning of reclaimed water allocation and use, water reuse classification, data collection, etc. |
