摘要
西北农村地区水资源匮乏且处理污水困难,严重制约当地居民生活水平的提高,结合西北地区丰富的太阳能资源,设计了一套基于太阳能光伏光热的污水处理系统。该系统主要利用热管式PV/T和闪蒸冷凝技术实现农村污水处理,以兰州1家4口生活污水为研究对象,对该系统进行实验研究,结果表明:系统可实现兰州农村地区1家4口的污水处理,且系统理论年发电量为2251.4 kW·h,二十年内可节约标准煤约13.5 t,减少CO_(2)排放量约44.95 t,SO_(2)排放量约1350.8 kg,氮氧化物排放量约675.42 kg。
The lack of water resources and the difficulty of sewage treatment in the rural areas of the northwest have seriously restricted the improvement of the living standards of local residents.Combined with the abundant solar energy resources in the northwest region,this paper designs a sewage treatment system based on solar photovoltaics.The system mainly uses heat pipe PV/T and flash condensation technology to realize rural sewage treatment.Taking the domestic sewage of a family of four in Lanzhou as the research object,the system is experimentally studied.The results show that the system can achieve a family of four in Lanzhou rural areas.The theoretical annual power generation of the system is 2251.4 kW·h,which can save about 13.5 tons of standard coal,reduce CO_(2)emissions by about 44.95 tons,reduce SO_(2)emissions by about 1350.8 kg,and reduce nitrogen oxide emissions by about 675.42 kg within 20 years.
