配水系统包括管道、贮水和附属设备 ,是水输送到用户的通道 ,应多方面采取措施防止污染。过去的设计力图使管道和贮水设备的安全系数过大 ,造成停留时间长 ,余氯消失 ,出现臭和味及其他水质问题。配水系统中使用的某些材料产生了适合微生物繁殖的条件 ,如无衬里的管道 ,或暴露 Water distribution system, including pipelines, water storage and ancillary equipment, are the channels through which water can be delivered to users. Measures should be taken to prevent pollution. In the past, the design sought to make the safety factor of pipes and water storage equipment too large, resulting in long residence time, residual chlorine disappearing, odor and taste and other water quality problems. Some of the materials used in water distribution systems create conditions that are suitable for the propagation of microorganisms, such as unlined pipes or exposed
