摘　　要：在水资源匮乏的当今,再生水的安全利用显得尤为重要。天津是我国严重缺水的资源性缺水城市之一,为改善资源性缺水的现状,要求城市杂用水均应使用再生水,这使得人体与再生水的直接或间接接触变得愈发频繁。本研究针对可用于室内冲厕的再生水,以天津某住宅小区为研究对象进行水力模拟分析,确定了再生水入户盲管的适宜长度,研究结果的应用可降低生物膜对水质的不利影响,提高末端用户的出水水质。The safe utilization of recycled water is particularly important in the current situation of water scarcity.Tianjin,as one of China’s resource-based cities facing severe water shortage mandates.In order to improve the current situation of resource-based water shortage,Tianjin requires the use of recycled water for municipal water,and this has led to an increasing frequent direct or indirect contact between human and reclaimed water.Aiming at the reclaimed water designated for indoor flushing,which is most directly exposed to the population,this study conducted hydraulic simulation analysis on a residential community in Tianjin.It calculated and analyzed the optimal length of the blind pipe for entering the household to ensure the biological stability of the reclaimed water.The application of the research results will reduce the adverse impact of the biofilm on the water quality and enhance the effluent quality for end-users.
