摘　　要：在我国一些偏远地区特别是农村地区,多采用布局灵活的分散型污水处理系统,但政府投资兴建的污水处理设施由于缺乏资金而无法正常运行.常规污水处理系统在运行过程中需要消耗大量电能,运行费用较高.本研究根据太阳辐射产电的周期性变化规律,结合污水生物处理过程中不同反应阶段对溶解氧的需求差异,建立了太阳能驱动一体化生物膜反应器.通过监测蓄电池电压的变化,获得实时电压作为控制参数,结合太阳光照强度和天气的变化,建立了高、中、低能耗以及夜间四种运行模式.对污水处理效果的研究表明:系统对有机污染物的去除效果在90%以上.Decentralized wastewater treatment systems are widely used in rural areas in China due to the flexible layout,however,lots of them are not well operated for the fund shortage. The high consumption of electric energy is a common condition in traditional wastewater treatment systems which increase the high maintenance fee. An integrated biofilm reactor driven by solar energy was set up based on the solar radia- tion cycle and the different oxygen demanded in the biological wastewater treatment process. The voltage of the storage battery combined with the solar radiation was used as the controlling parameter according to which four different operational modes was conducted. In addition,over 90% of the organic pollutants were removed in this wastewater treatment system.
