摘要
屋面雨水收集利用系统主要有两种:常规和绿色屋面雨水收集利用系统。基于常规屋面雨水收集利用系统的工作原理,阐述了屋面雨水的收集、处理和回用方法,提出了虹吸雨水系统应用于屋面雨水收集利用系统所具有的特点、难点及对策。基于绿色屋面收集利用系统的结构及工作原理,阐述了绿色屋面作为雨水处理环节的预处理单元所具有的削减洪峰流量和净化水质的潜能,并结合绿色屋面的功能和局限性,提出绿色屋面的价值应综合其生态、能源、美学、商业效益来考量。归纳了常规和绿色屋面雨水收集利用系统在结构、屋面雨水处理效果、应用方面的特性,对比了二者各自的优势与不足。
There are two main types of roof rainwater collection and utilization systems: conventional and green roof rainwater collection and utilization systems. Based on the working principle of the conventional roof rainwater collection and utilization system, the methods of collection, treatment, and reuse of roof rainwater are described. The characteristics, difficulties, and countermeasures when siphon rainwater system applied to the roof rainwater collection and utilization system are proposed. Based on the structure and working principle of green roof, the potential of green roof as a pretreatment unit for rainwater treatment to reduce flood peak flow and purify water quality is expounded. Combined with the function and limitations of the green roof, it is concluded that the value of the green roof should be considered in combination with its ecological, energy, aesthetic and commercial benefits. The characteristics of conventional and green roof rainwater collection and utilization system in structure, effects, and application are summarized, and the advantages and disadvantages of the two are compared.
