摘　　要：通过对无负压供水系统的典型试用小区进行现场测试,并结合管网模型的实时模拟结果,研究了无负压供水系统的使用对市政供水管网的影响。结果表明,在市政供水量满足要求的条件下,无负压供水系统正常使用时的压力波动与市政供水管网的基本一致,该系统的使用对市政供水管网的影响不大。采用无负压供水系统时,市政供水管网在使用区域的供水量应能满足用户最大小时用水量的要求,且接入处的供水管网的管径不宜小于300mm。The effect of non-negative pressure water supply system on municipal water distribution network was studied by field testing the system in a typical residential area and based on the real time simulation result with the network model. The results show that when the municipal water supply meets the requirement, the pressure fluetuation of non-negative pressure water supply system during its normal operation is the same as that of municipal water distribution network, and its application has a negligible effect on municipal water distribution network. When the non-negative pressure water supply system is used, the water supply of municipal water distribution network in its service area should meet the consum- er requirement for the maximum hourly water consumption, and the diameter of municipal water distribution network connected with non-negative pressure water supply system should not be less than 300 mm.
