摘　　要：造纸工业是一个高能耗、高水耗、高污染的行业。在当前国家能源紧缺、造纸业市场竞争激烈的局势下,降低能源费用支出、提升市场竞争力,关系到每个造纸厂的生存与发展。由于处理水量大、废水需氧量高等原因,造纸厂污水处理的能耗费用在工业废水处理中居于前列。选取造纸行业内有代表性的污水处理厂,通过分析污水特点及工艺流程,并进一步分析能耗结构,寻找污水处理厂节能降耗的方法。经过分析,电耗占污水处理总能耗的60%~90%,好氧处理工序的能耗在所有工序中最高,各工序的主要耗能设备是泵与风机。从工艺设计、设备配置、工艺运行、日常管理等方面提出节能策略,以期做好全流程的节能降耗工作。本研究旨在为新扩建污水处理厂在设计、运行环节提供节能策略,实现污水处理厂可持续发展。Paper industry has high energy consumption,high water consumption and high pollution characteristics.Under the current situation of national energy shortage and fierce competition in the paper industry market,how to reduce energy costs and improve market competitiveness is related to the survival and development of each paper mill. Due to the large amount of treated water and the high oxygen demand of wastewater,the energy consumption cost of water pollution control ranks in the forefront of industrial wastewater treatment. Taking the representative sewage treatment plant in the paper industry as the research objects,the characteristics of sewage,technological process and energy consumption structure were analyzed,so as to find the ways to save energy and reduce consumption in sewage treatment plants. After analysis,the power consumption accounted for 60%-90% of the total energy consumption of sewage treatment,the energy consumption of aerobic treatment process was the highest among all processes,and the main energy consuming equipment of each process were pump and fan. This study put forward energy-saving strategies from the aspects of process design,equipment configuration,process operation,daily management,etc.,in order to do a good job of energy saving and consumption reduction in the whole process. The aim of this study was to provide energy-saving strategies for the design and operation of new and expanded sewage treatment plants,so as to realize the sustainable development of sewage treatment plants.
