最近颁布的《消毒剂/消毒副产品规则》引发了人们对替代传统使用氯消毒饮用水供应的兴趣。臭氧已成为替代氯的主要候选物质，因为它不会产生现在受联邦法规监管的氯化副产品。虽然使用臭氧比使用氯有许多优点，但水和臭氧之间的适当接触至关重要。设计不当会导致臭氧损失、成本过高、运行效率低下，最重要的是，水质较差。研究了几种接触类型，以确定最佳效率、设计和尺寸限制以及操作考虑。 接触器类型包括配备多孔板的多挡板反应器、涡轮接触器、静态混合器和文丘里反应器。本文概述了它们在传递和水力特性方面的性能。最后，介绍了计算机工具，以帮助工程师更好地设计臭氧反应器，并帮助水处理厂的操作员更有效地运行臭氧装置。

The recently promulgated Disinfectant/Disinfection By-Product Rule has triggered interest in alternatives to the traditional use of chlorine for the disinfection of drinking water supplies. Ozone has emerged as a prime candidate to replace chlorine, since it does not produce the chlorination byproducts now regulated under the federal rule. Although the use of ozone offers a number of advantages over chlorine, proper contact between water and ozone is critical. Improper design can lead to ozone loss, excessive cost, inefficient operation, and most important, inferior water quality. Several contact types were investigated to determine optimal efficiency, design and size constraints, and operational considerations. Included among the contactor types were multibaffled reactors equipped with porous plates, turbine contactors, static mixers and venturi reactors. This paper is an overview of their performances in terms of transfer and hydraulic behavior. Finally, computer tools are presented to help engineers better design ozone reactors and aid operators of water treatment plants to operate an ozone installation more efficiently.
