摘要
主要从优化消毒的角度介绍优化清水池水力条件的必要性和原理,以及停留时间函数在清水池研究中的应用。根据Froude相似定律,以深圳市笔架山示范工程的清水池为原型设计中试模型,并进行不同条件下的示踪试验,证明不同清水池导流板设置条件对t10/T的影响,并据此建议原型清水池的设计条件。通过对深圳水务集团的若干清水池进行示踪研究,得到各清水池的停留时间分布函数和t10/T等参数,并对试验结果进行了讨论。
The principles to optimize the hydraulic state of clear water tank and the applied time retention function ( residence time distribution) for these are presented. On the basis of Froude's Similarity Law a pilot clear water tank is designed from the practice in demonstration project of Bijiashan Waterworks. Tracer tests show that parameter t10/T can be improved with baffle walls and the results have been applied to the design of full-scale clear water tank. Other discussions on residence time distribution and t10/T are presented for tracer tests done on several existing tanks in waterworks of the Shenzhen Water Supply (Group).
