现状某处理规模为 10× 10 4ｍ3 /ｄ的净水厂建成于 2 0世纪90年代中期 ,服务人口为 2 0余万人 ,其净水工艺和水质监测流程如图 1所示。图 1　净水工艺和水质监测流程该工艺需连续监测的数据主要包括 :原水、沉后水、滤后水和出水的浊度、ｐＨ值、余氯量。监测仪表包括 :浊度仪 Status A water treatment plant with a treatment capacity of 10 × 10 4 m 3 / d was built in the mid-1990s and serves 20 million people. The process of water purification and water quality monitoring are shown in Figure 1. Figure 1 water purification process and water quality monitoring process The process to be continuously monitored data include: raw water, sedimentation water, filtered water and water turbidity, pH, residual chlorine. Monitoring instruments include: turbidity meter
