摘　　要：建筑中水回用是缓解城市水资源短缺问题的重要途径之一,而设计秒流量计算方法是保障建筑中水系统合理设计的重要基础.但目前我国设计规范中未明确给出中水系统设计秒流量的计算方法。基于此,探讨了目前国际上设计秒流量常用计算方法亨特概率法、俄罗斯概率法以及我国现行《建筑给水排水设计标准》(GB 50015-2019)概率法的原理及其对住宅中水系统的适用性,并以此为基础,针对北京地区487户1761人开展了问卷调查,得出了中水系统中便器的用水规律,进一步提出适宜于住宅建筑中水系统的设计秒流量的计算方法。Reuse of water in buildings is one of the important ways to relieve the problem of urban water shortage,and the calculation method of design peak flow is an important foundation to ensure the reasonable design of water systems in buildings.However,the calculation method of the design peak flow rate of the reclaimed water system is not clearly given in the design standard of our country at present.Based on this,discuss the principles and applicability of the current internationally commonly used Hunter Method,Russian Method and Standard for design of building water supply and drainage(GB 50015-2019).And in this basis,a questionnaire survey was carried out for 487 households with 1761 people in Beijing,and the law of water use in the toilet in the reclaimed water system was obtained,further proposes a calculation method suitable for the design peak flow of the reclaimed water system in the residential building.
