摘要: 随着城市化快速推进,农村污水处理设施建设严重滞后,部分污水直接溢流入河所造成的水体污染及环境恶化问题日益突出。控源截污并收集处理是劣Ⅴ类水体源头治理的最重要手段。研究分析了农村典型河道水体劣Ⅴ类成因,对农村污水处理设施进行扩容及升级改造,并引入熵的理念解析了有机物、氮磷削减对水环境的影响及减排效果。800 m3/d规模农村污水处理设施升级改造到1800 m3/d后可有效改善典型河道水体环境,减少的年熵增为9.80×107 kJ/K。河流水环境、水生态生态系统稳定需要熵增-逆熵增过程中保持相对平衡,熵增评估对污水厂升级改造及溢流污染治理有一定的现实意义。在国家碳排放、碳中和、劣Ⅴ类水体治理的大背景下,熵概念下的可持续污水处理有望会成为新技术评估的发展方向。Abstract: The issue of water pollution and environmental deterioration caused by insufficient processing capacity sewage treatment in rural areas is a critical problem that requires immediate attention. The current rate of urbanization has led to severe neglect of the construction of sewage treatment facilities in rural areas, causing the direct injection of untreated sewage into rivers. Source control, pollution interception, collection, and treatment are essential methods for controlling the pollution of Inferior V-class water bodies. In this paper, we conducted an in-depth analysis on the csuse of the inferior V-class water bodies in typical rural river water, expanded and upgraded rural sewage treatment facilities, and introduced the concept of entropy, to analyze the impact of organic matter, nitrogen, and phosphorus reduction on water environment and emission reduction effect. After upgrading rural sewage treatment facilities from 800 m3/d to 1800 m3/d, the water environment of typical river channels was effectively improved, and the annual entropy increase was reduced by 9.80×107 kJ/K. The stability of the river water environment and water ecosystem depends on maintaining a relative balance between entropy increase and reverse entropy increase. Evaluating the increase in entropy has practical significance for upgrading and renovating sewage plants and controlling the effect of overflow pollution. In the current context of carbon emissions, carbon neutrality, and the treatment of Inferior V-class water bodies, the sustainable treatment of sewage under the concept of entropy will be excepted to be a development focus of new technology evaluation.
