通过浙江大学西溪校区东一教学楼改造的雨水收集工程实践,分析了本地的气象资料、回用水使用与降水时段调节等,将房间空调器凝结水与饮用水反渗透浓水予以收集归入整个雨水收集系统,用于教学楼周围的绿化浇灌与景观水的补水.通过计算,教学楼夏季空调器凝结水量约为3.48 m3/d,每日饮用水反渗透浓水的水量可达到198~396 L.在气温较高的夏季能有效地补充因大量蒸发导致绿化浇灌及景观补水不足的缺陷,同时在降雨量较少的冬季也能一定程度上进行添补.雨水与冷凝水以及反渗透浓水一同收集大大提高了整个收集系统的经济性.项目实测数据验证了系统的经济合理性.
Through the practice of rainwater collection in the transformation of Dongyue Teaching Building of Xixi Campus in Zhejiang University, this paper analyzes the local meteorological data, the use of reuse water and the adjustment of precipitation period, and collects the condensate of RO and RO of drinking water in the room as the whole Rainwater collection system is used to replenish greening water and landscape water around the teaching building.Through calculation, the amount of condensate water in summer air conditioner in teaching building is about 3.48 m3 / d, and the daily amount of reverse osmosis water for drinking water can reach 198 ~ 396 L. In the hotter summer season, it can effectively replenish the shortcomings of green watering and landscaping due to large amount of evaporation, and can also be partially supplemented in winter with less rainfall. Rainwater and condensate as well as reverse osmosis concentrated water Collected together greatly improves the economy of the entire collection system. Project data confirm the economic rationality of the system.
