摘要:
深圳市光明区某给水厂处理工艺是常规的“混凝—沉淀—过滤—加氯消毒”工艺，滤池为V型滤池。通过研究V型滤池各类阀门严密性对滤池运行效果的影响，发现V型滤池各类阀门严密性对于滤池反冲洗强度、效果以及出水浊度、菌落总数等具有重要意义，尤其是滤池出水调节阀，对于滤池出水浊度和菌落总数的控制尤其重要。给水厂在运行维护过程中应定期排查V型滤池各类阀门的严密性，严格把控滤池出水调节阀的密闭性，加强管理，及时更新，有助于降低出水浊度和菌落总数异常的风险，确保出厂水水质安全可控。
Abstract:
The water purification process of a waterworks in Guangming District of Shenzhen City is regular “coagulation-sedimentation-filtration-chlorine disinfection”, and the filters are V-type filters. Influence of the tightness of all kinds of valves on the operation of the V-type filters was investigated. All kinds of valves in the V-type filters were of great significance to backwashing strength, backwashing effect, effluent turbidity and total bacterial count of the filters, especially for effect of outlet regulating valve on effluent turbidity and total bacterial count. During the operation and maintenance of the waterworks, the tightness of all kinds of valves in the V-type filters should be checked regularly, the closeness of the outlet regulating valve should be strictly controlled, the management should be strengthened, and the devices should be changed in time. These measures are helpful to reduce the risk of abnormal turbidity and total bacterial count to ensure the safety of effluent quality.
