Abstract: The wastewater treatment technology of a wastewater treatment plant in Linjiang, a typical small town in Northeast of China, has been taken as an example. The energy saving and consumption reducing measures taken by this wastewater treatment plant are summarized. Combined with the running results, the validity of the measures is evaluated. The results show that through the promotion of automatic control of pumps, blowers and sludge dewatering machine, the running energy consumption of the wastewater treatment plant can be reduced obviously.

Key words: wastewater treatment plant, energy consumption, energy-saving technologies

摘要： 以东北地区典型中小城镇临江市污水处理厂的污水处理工程为实例，归纳总结了该污水处理厂所采用的节能降耗措施，并结合运行结果，对措施的有效性进行了评价。结果表明，通过对污水提升泵、鼓风机和污泥脱水机进行自动控制，可明显降低污水处理厂的运行能耗。
