摘要: 市政生活污水处理是高能耗行业。以长沙经济技术开发区城南污水处理厂(二期)为例,通过对污水处理厂的预处理、Carrousel氧化沟、污泥处置和管理等方面进行分析发现,该处理厂平均电耗为0.199 kW•h/m3,其中预处理、Carrousel氧化沟、反硝化系统、超滤系统分别占总耗电量的16.53%、44.28%、18.26%、10.93%。结合国内外先进污水处理厂能耗情况对比分析,发现市政生活污水处理厂存在较大节能降耗潜力,其主要途径包括精细化综合规划设计,开发新型节能降耗的污水处理技术和设备,研究水处理工艺过程中精准控制技术,建立节能降耗效能综合评价体系与方法等。其不仅可满足持续发展的需求,也将极大地促进污水处理行业发展。

Abstract: Municipal sewage treatment is an industry with high energy consumption. Taking the Chengnan Sewage Treatment Plant (Phase II) in Changsha Economic and Technological Development Zone as an example,the pretreatment,Carrousel oxidation ditch,sludge disposal and management of the sewage treatment plant are analyzed. The average power consumption is 0.199 kW•h/m3,of which the pretreatment,Carrousel oxidation ditch,denitrification system,and ultrafiltration system account for 16.53%,44.28%,18.26%,and 10.93% of the total power consumption,respectively. Combined with the comparative analysis of energy consumption of advanced sewage treatment plants at home and abroad,it is found that municipal sewage treatment plants have great potential for energy saving and consumption reduction. The main approaches include refined comprehensive planning and design,development of new energy-saving and consumption reduction sewage treatment technologies and equipment,and research on precise control technology in water treatment processes,establishment of a comprehensive evaluation system and method for energy saving and consumption reduction efficiency and so on. The approaches can meet the needs of sustainable development and greatly promote the development of the sewage treatment industry.

Key words: wastewater treatment, energy consumption distribution, energy saving and consumption reduction
