科罗拉多州丹佛市正在通过一个1-mgd（3.8-ML/d）的全规模示范工厂，测试将处理后的废水直接处理为饮用水的可行性。介绍了示范工厂的特点，包括处理机组、工厂的计算机系统和安全注意事项。文中给出了电厂运行的施工和启动阶段的详细信息。本文还介绍了迄今为止的研究结果和健康影响研究计划，以及获得公众接受直接再利用的项目。该项目预计将提供必要的信息，以评估直接再利用的可行性，尤其是对于位于水城地区的城市，在这些地区，开发更传统的水资源的成本越来越高，无论是在环境方面还是在资本投资方面。 包括5个参考文献、表格、图表。

The feasibility of directly treating processed wastewater plant effluent to potable quality is being tested in Denver, Colorado, with a full-scale, 1-mgd (3.8-ML/d) demonstration plant. Special features of the demonstration plant are described including the treatment train, the plant's computer system, and safety considerations. Details of the construction and start-up phases of plant operation are given. Results to-date and plans for health effects research, and programs to gain public acceptance of direct reuse are also addressed. This project is expected to provide the information necessary to evaluate the feasibility of direct reuse, especially for cities located in waterscarce areas where development of more conventional water resources is becoming increasingly costly, both in terms of the environment and in capital investments. Includes 5 references, tables, figures.
