水厂运行的节能降耗措施探析

Discussion on energy saving and consumption reducing measures for water plant operation

近年来,随着我国城市化进程不断加快,供水行业的能源消耗与日俱增.据统计,给水系统的能耗中现状的动力费是所有水厂费用支出中最主要的部分,占到总制水成本的60%以上.节能降耗对降低制水成本可起到至关重要的作用.本文分析江西省宜春市上高县城第二水厂的改造措施,得出以下结论:通过对水厂泵站变频改造前后能耗实测数据对比分析可知,泵站变频改造节能降耗效果明显.通过对消毒剂药耗方面的调研,得出了更佳的供药方法与路线,在保证水质安全的前提下,降低了供水成本,节约了能耗.

In recent years,with the continuous progress of science and technology and the rapid development of social economy in China,the energy problem has been widely concerned by people from all walks of life.Now many industries in China are implementing energy saving measures.With the accelerating process of urbanization in China,the energy consumption of water supply industry is also increasing.The second water plant in Shanggao County,Yichun City,Jiangxi Province is studied in this aritcle.According to statistics,the power cost of water supply system is the most important part of all water plant expenses,accounting for more than 60%of the total water production cost.Therefore,for the operation cost of water plant,energy saving and consumption reduction can play a crucial role.Through the research and transformation of the water plant,the following conclusions are drawn.Based on the actual measurement and analysis of the pumping station in the existing water plant,this paper puts forward the transformation of the pumping station by frequency conversion debugging,and makes an economic comparative analysis of the energy consumption of the transformed pumping station.The analysis shows that the effect of energy saving and consumption reduction is remarkable.Through the study of disinfectant consumption,a better drug supply method and route are obtained.Under the premise of ensuring the safety of water quality and quantity,the cost of water supply is reduced and the energy consumption is saved.
