超高层建筑重力能纳滤雨水回用系统构想

Conception of Gravitation Energy Nanofiltration Rainwater Reuse System for Ultra-high-rise Buildings

在过去几十年中,随着城市化的不断推进,带来城市排涝日渐困难和建筑供水成本持续增加这两大典型矛盾,由此提出超高层建筑重力能纳滤雨水回用系统构想。对超高层建筑屋顶、外立面全方位收水,利用重力落差代替压力水头进行纳滤膜过滤,全程无能耗,出水达到自来水标准,阶梯式回用。重力能纳滤系统对于减少高层建筑供水能耗具有显著的经济效益,对于减少城市雨洪径流,降低排水系统成本,发挥海绵城市效应方面具有卓越的环境、生态效益。

A newly conception of using gravitation energy for nanofiltration rainwater reuse system in Ultra-high-rise buildings was proposed in the background of both the urban drainage becoming increasingly difficult and the water supply costs continue rising due to the urbanization events move forward constantly in the past few decades. Raw water was collected from both the rooftops and the outside surface of the Ultra-high-rise buildings. This process can operate without any extra energy consumption due to the gravity energy utilized to replace the pump to provide sufficient pressure for the nanofiltration process. After that treatment,the water quality can reaches the standard of drinking water. This system has significant economic benefits in reducing the energy consumption of water supply for Ultra-high-rise buildings and has excellent environmental and ecological benefits in decreasing urban rainwater runoff,cutting down drainage system cost and exerting sponge effects.
