摘要
城市污水处理是一种高能耗的产业。污水处理过程消耗的能源主要包括电能和燃料、药剂等。本文从城市污水处理厂的污水提升,污水处理工艺,污泥处理以及管理方面,分析污水处理过程中的耗能情况,并提出各处理阶段,特别是污泥厌氧消化工艺的节能降耗途径。综合以上分析,城市污水处理厂有较大的节能降耗潜力,通过改进工艺、引进新技术、建立完善的节能管理机制,将是今后污水处理厂节能降耗的重要途径。
Urban sewage treatment is a high energy consumption industry.The energy consumed in this treatment process mainly included electrical energy,fuel,chemical agent and so on.Energy consumption condition in sewage treatment process were analyzed,and energy saving and reducing consumption approach in each part,especially in sludge anaerobic digestion process was proposed from some aspects,that was sewage pumping,sewage treatment process,sludge treatment and management of urban sewage treatment.In conclusion,urban sewage treatment plant had large potential in energy saving.Energy saving and consumption reduction of urban sewage treatment plant will be enhanced by improving the process,introducing new techniques,and consummating management mechanism of energy saving.
