屋面雨水利用中初期弃流装置的探讨

Discussion on the Initial Split-flow Device in Roofing Rainwater Utilization

初期雨水弃流是屋面雨水利用中的重要因素之一，而设计合理高效的弃流装置用以保证初期雨水弃流顺利进行显得非常有必要。在研究国内一些弃流池优缺点的基础上，从占据空间小、高效率等特征出发，提供了一种设计初期弃流装置的新思路。同时从工作原理上进行了可行性分析和与旧装置的比较分析。结果表明，这种新装置具有实用性强、自动控制、维护简便等优点，因而是一种值得推广应用的新型屋面雨水初期弃流装置。

Initial split-flow is one of the important factors existing in roof rainwater utilization, it is quite necessary to design proper and highly effective split-flow devices to guarantee the smooth process of initial rainwater split-flow. Based on study of domestic different split-flow devices, with regard to small occupying space, high efficiency and other features, the paper proposes a new idea of initial split-flow device design The results show that the new device, characterized by advantages of strong practicality, automatic control.easy maintenance and etc, is worthy of being promoted.
