摘　　要：再生水是解决北京市景观用水来源的必要途径。由于富含N、P等营养盐,再生水用于景观水体易产生以绿藻为主的水华。DePAT系统由旁滤、水力改善及生态强化系统共同组成,可以成功抑制再生水水华,在夏季能够将藻计数控制在108个/L以下。试验表明优化选择DePAT工艺,可以实现良好的景观水体脱色除臭功能。Reclaimed water is an important resource for the landscape in Beijing. Green alga often breaks out in summer because of the nitrogen and phosphorus contents in wastewater. DePAT process can control the growing of green alga, it is composed of side-flow filtration, hydraulic enhancement and ecological improvement. In the pilot test, the amount of alga was less than 10^8 per liter and the color and odor of the landscape water body were best preserved.
