摘　　要：单格滤池安装一组浊度仪,能及时反映滤后水浊度的变化,即使在现场操作人员不能观察到池面反冲洗异常情况下,也能及时诊断问题滤池。当待滤水的浊度与滤后水的浊度无明显变化时,投加助滤剂可有效降低滤后水的浊度。合理确定初滤水排放时间,降低滤后水中的颗粒物。池壁和排水槽生长藻类,可采用遮光措施,控制池内藻类生长,有利于降低饮用水中的藻类浓度,提高滤后水水质。The installation of a set of turbidimeters in single cell filter can timely reflect the change of turbidity of filtered water,even if the on-site operator is unable to observe the abnormal backwashing of the pool surface,the problem filter can be diagnosed in time.When the turbidity of the water to be filtered has no significant changes as that of the filtered water,adding filter aid can effectively reduce the turbidity of the filtered water.Reasonably determine the discharge time of the primary filtered water in order to reduce the particulate content in the filtered water.When algae grow on the pool wall and drainage pool,shading measures can be adopted to control the growth of algae in the pool and help to reduce the concentration of algea in drinking water and improve the water quality after filtration.
