太阳能在污水处理厂中的运行模式

Operation Mode for Wastewater Treatment of Solar Energy

我国太阳能资源丰富,陆地表面每年接收太阳能辐射总量达3.4×103~8.4×103 MJ/m2。污水处理厂因其占地面积大、高能耗等特点,与太阳能应用具有潜在的共生优势。文章主要通过污水处理厂两大处理内容——污水处理和污泥处置过程中的不同环节介绍了相应的太阳能应用技术,并通过实际案例及相应模拟计算,分析了污水处理厂的整体能耗及经济效益。结果表明,太阳能应用于污水处理厂中可大大降低其能耗和运营成本。

China is rich in solar resources,the global solar radiation reaching on the earth’s surface is up to 3.4×103~8.4×103 MJ/m2 in a year.With characteristics of large areas and high energy consumptions,sewage treatment plant has synergistic potentials to solar applications.In this work,solar applications in sewage treatment process and sludge disposal process in sewage treatment plant were studied.The overall energy consumptions and economic benefits of sewage treatment plants were analyzed through case studies and simulations.Results showed that,after combining with solar energy,the running costs and energy consumptions of the plants were largely reduced.
