摘要:
针对南方地区雨水资源充沛的特性,对低层住宅楼雨水资源化利用的可行性和潜力进行分析,提出通过设置屋顶与地面2个水箱进行雨水收集,利用泵管连接2个水箱实现相互补给以供住宅自压冲厕和小区景观利用的方法,从而达到节约能源、充分利用雨水资源和减少城市排涝压力的目的; 并以系统利用效率最大为目标,优化了水箱集蓄容积,可为海绵城市建设提供新思路。实例分析了扬州地区不同降雨水平年条件下,该系统每单元户楼顶水箱可自压集蓄利用雨水量60～100 m3·a-1,节省提水送到楼顶电能平均20 kWh·a-1; 楼上与楼下2个集水箱联合调度可集蓄利用雨水总量250～310 m3·a-1,也达到减少利用自来水量和减少城镇的排水压力量。由每单元户拦蓄利用雨水资源数量来看,虽数量有限,但推及整个城镇影响将十分巨大。
Abstract:
In view of the abundant characteristics of rainwater resources in south China, the feasibility and potential of rainwater resources utilization in low-rise residential buildings were analyzed. The method of collecting rainwater by setting two water tanks on the roof and the ground was put forward, and two water tanks were connected by the pump pipe to supply each other for the self pressure toilet and the use of the residential landscape in the residential area, so as to save energy, make full use of rainwater resources and reduce the pressure of urban drainage. At the same time, taking the maximum efficiency of the system as the goal, the volume of water tank storage was optimized, which could provide new ideas for the construction of sponge city. It's analyzed that under different rainfall level in Yangzhou, the water tank in the system could collect and store rainwater volume by 60～100 m3·a-1 for each unit, and the average energy of water pumping to the roof was 20 kWh·a-1. The combined operation of two water tanks on the upstairs and downstairs could collect and utilize the total amount of rainwater 250～310 m3·a-1, which could reduce the use of tap water and reduce the drainage pressure in cities and towns. The amount of rainwater resources collected by each unit was limited, but the impact on the whole town would be enormous.
