| 摘 要： | 利用砂滤-超滤组合工艺处理景观湖水,对5种常用水质指标进行了连续15 d的监测.经组合工艺处理后,湖水的浊度及COD、TOC、TN和TP的去除率分别达到99%、51%、91%、89%和92%,处理后的水质达到国家地表水Ⅳ类水质标准,能够满足景观用水要求.整个运行期间,卷式超滤膜过滤平均通量维持在95 L/（m2·h）左右,组合工艺运行稳定可靠.

| Abstract: | An integrated sand filter-uhrafiltration process was carried out to treat landscape water pollution, and 5 common water quality indexes were continuously monitored for 15 days. The turbidity, COD, TOC, TN and TP removal efficiencies in lake water treatment achieved 99 %, 51%, 91%, 89% and 92%, respectively. The quality of treated lake water meets the requirements for Level 1V in the national surface water quality standard, and that for landscape water. In addition, the membrane flux maintained about 95 L/（ m2- h） during the operation period, indicating that the integrated process was stable and reliable. |
