给水厂预臭氧接触池设计计算

Design and Calculation of Pre-ozonation Contact Tanks in Waterworks

探讨了水厂中预臭氧接触池各系统的设计计算方法,优化了接触池的管道布置方法。重点讨论了臭氧系统水射器增压水系统设计,给出了增压水泵的流量与扬程的计算方法,建议应优先选择沉后水作为增压水系统水源。提出了新建与改建水厂中预臭氧接触池的不同超越方式,分析了不同规模水厂预臭氧接触池更宜采用的叠合设计形式。

Design calculation of pre-ozonation contact tanks in waterworks was discussed. In the design process, the layout of pipes scheme in the contact tanks was optimized. Pressurized water system for efflux installation of ozonation unit was fully introduced. Calculation methods of pressure pump＇ s flow and head were put forward. And furthermore, the effluent of sediment was recommended as the priority of the water source of the pressure water system. In new-built water plant, the surpassing mode of pre-ozo nation contact tank which was different from that in reconstruction plant. The appropriate superposition modes of pre-ozonation contact tank based on the water plant capacity were summarized as well.
