电力改革政策下昆明市污水处理厂降低用电成本分析

Analysis on Reducing Electricity Costs at Kunming Wastewater Treatment Plant Under Power Reform Policies

污水处理厂运行的结果直接关系一座城市生产文明建设的情况,在污水处理厂运行过程中,电费成本根据污水厂的工艺不同,分别占到工厂经营成本的25%~35%,合理的用电成本管理对节约工厂经营成本至关重要。新电力改革政策,对污水处理厂节能降耗起到了促进作用。通过对昆明市范围内典型的四座污水厂近两年执行电力改革政策的成果进行分析,2022年参与交易方式以年度交易为主,年度交易占总用电量的70%,剩余约30%用电量用月度交易进行调整,一次性打捆交易,整体价格具有优势,比2021年共计节约电费149万元,节约成本空间大;同时,把握好枯水期、平水期的交易价格,参与电力市场交易,相对于未执行的情况下,用电成本节约35%~45%,相关经验对污水处理厂的运营起到借鉴与示范作用。

In a city,the operation of sewage treatment plants is directly related to the construction of civ-ic production.During the operation of sewage treatment plants,electricity costs account for 25%~35%of the operating costs depending on the processes used.Effective electricity cost management is crucial for saving on operating expenses.The new power reform policies have promoted energy saving and consump-tion reduction in sewage treatment plants.This paper analyzes the results of four typical sewage plants in Kunming over the past two years.In 2022,the main transaction mode was annual transactions,which ac-counted for 70%of total electricity consumption,while the remaining 30%was adjusted through monthly transactions.One-time bundled transactions provided an overall price advantage,saving a total of 1.49 million yuan in electricity costs compared to 2021,indicating significant cost-saving potential.Addition-ally,by leveraging transaction prices during low-water and flat-water periods and participating in electric-ity market transactions,electricity costs were reduced by 35%~45%compared to non-implementation scenarios.These relevant experiences provide valuable insights and serve as a model for the operation of sewage treatment plants.
