DAT-IAT 工艺处理城市污水

Municipal Wastewater Treatment by DAT-IAT Process

连续进水、连续—间歇曝气（ＤＡＴ—ＩＡＴ）工艺是利用单一ＳＢＲ反应池实现连续运行的新型工艺，它既有传统活性污泥法的连续性和高效性，又具有ＳＢＲ法的灵活性，适用于水质水量变化大的情况。本文首次对利用该工艺处理城市污水进行了研究和设计，介绍了该工艺的特点、工作过程和工艺设计。

Demand Aeration Tank-Intermittent Aeration Tank(DAT-IAT)process is a new process using a single Sequencing Batch Teactor(SBR)to operate continulusly.The operation of this process is between the conventional activated sludge and the typical SBR process with advantages of continulus infolw,high efficiency and tolerant of large variations in wastewater quality and quantity.The study on and design of a municipal wastewater treatment plant adopting this process were described in the paper.An introduction to the process characteristics,the working process and the design were also included. \ \
