污水处理厂能耗分析及节能措施探讨

Energy Consumption Analysis and Energy Saving Measures of Wastewater Treatment Plants

针对我国城镇污水处理厂现有的污水处理工艺能耗高及投资费用大的问题,分析探讨了相关的污水处理工艺如下:A/O工艺、A^2/O工艺、氧化沟工艺、SBR(序列间歇式活性污泥法)工艺的主要能耗点,并对污水处理厂的预处理过程、生化处理过程、污泥处理过程等提出了一些节能降耗的措施。该措施有利于城市污水处理厂根据具体的工艺情况,对污水处理工艺进行改进和分析,达到节能降耗,实现可持续发展。

In view of the high energy consumption and high investment cost of the existing wastewater treatmentprocess in urban sewage treatment plants in China, the main energy consumption point of the related wastewater treatmentprocesses, such as A/ O process, A2/ O process, oxidation ditch process and SBR （sequence batching）, were analyzedand discussed. Some energy saving measures for the pretreatment process, biochemical treatment process and sludgetreatment process of the sewage treatment plant were put forward. This measure was conducive to urban sewage treatmentplant in accordance with the specific process conditions, which could improve and analyze the sewage treatment process,achieve energy saving and sustainable development.
