摘要

摘要: 研究对长江上游9个省份、自治区、直辖市及51个主要城市进行了系统分析,探讨了污水处理与再生利用状况及再生水利用潜力。并以四川省和泸州市为例,对长江上游的再生水利用政策、规划和提升方案进行研究。2021年,长江上游51个主要城市再生水利用总量为10.1亿m³,预计未来年利用量仍有6.7亿~13.4亿m³的增长空间。长江上游不同城市再生水利用量和利用率存在明显差异。上游28个城市的再生水利用率在25%以下,仍有较大提升空间。通过对泸州市再生水定价策略分析、污水处理与再生利用运营模式探讨及相关政策制定分析,提出了基于目标分析和流程规划的再生水利用政策制定思路,旨在进一步规范和提升泸州市及长江上游主要城市再生水利用率和利用效益。

Abstract: The sewage treatment and reuse situation, and water reuse potential in 9 provinces (autonomous regions, municipalities) and 51 selected cities in the upper reaches of the Yangtze River Basin were systematically analyzed. The reclaimed water utilization policy, planning, and upgrading plan of typical areas in the upper reaches of the Yangtze River, were discussed, taking Luzhou City, Sichuan Province as an example. In 2021, the total amount of reclaimed water used by the 51 selected cities in the upper reaches of the Yangtze River Basin was 1.01 billion m³, and it was estimated that there will be a potential growth of 0.67 billion to 1.34 billion m³ per year in the future. There were significant differences in reclaimed water reuse quantity and rate among the selected cities in the upper reaches of the Yangtze River Basin. The water reuse rates of 28 upstream cities of the Yangtze River Basin were less than 25%, and obviously there is huge room for improvement. Through the analysis of the pricing strategy of reclaimed water in Luzhou City, the discussion on the operation mode of sewage treatment and reuse, and the analysis of relevant policies, the objective based analysis and process planning of the policy formulation of reclaimed water use was proposed, to further standardize and improve the utilization rate. In general, the policy formulation of reclaimed water utilization proposed in this paper is not only applicable to Luzhou City, but also provides a useful reference for other important cities in the upper reaches of the Yangtze River. Through scientific and reasonable pricing mechanism, flexible and diversified operation mode and systematic policy guarantee, it can effectively improve the utilization efficiency of reclaimed water, and promote the sustainable development of regional water resources, and contribute to the realization of the goal of ecological civilization construction.
