【摘要】 针对自来水厂净水工艺特点和消毒技术现状,就二氧化氯应用于自来水消毒的使用条件、投加方式、安全控制、设备选型、投加浓度等工艺参数进行了讨论。通过分析消毒系统可能出现的二氧化氯泄漏、断料和系统过压等安全隐患,提出了系统安全运行的保证措施。另外对二氧化氯投加量设计及出厂水余量的检测方法进行了探讨,对二氧化氯的消毒成本也进行了估算,供自来水厂参考。更多还原

【Abstract】 Matched with the water treatment process and the current disinfection situation of rural area waterworks, the technical parameters such as application condition, throwing method, safety control, equipment choice and the ClO2 dosage in sanitizing process are discussed. The system insurance measure are suggested to solve the safety shoal such as leak of ClO2, lack of raw materials, and overpressure of system occurred possibly in disinfection process. In addition, the dosage and the testing method of ClO2 in drinking water are presented, and the disinfecting cost with ClO2 is estimated for waterworks to consult.更多还原
