A basic information database of Gaobeidian sewage treatment plant was built based on literature research, data collection and dynamic remote sensing monitoring on the plant working condition by GF-1/GF-2 high-resolution satellites in 2015 .The results showed that there were algae in a secondary sedimentation tank in the plant according to the images by GF-1 on 16th February and 25th March 2015, and algae was found in 5 sec-ondary sedimentation tanks and the aeration tank corridor by GF-2 images on 2nd September, being suspected not working properly .8 sludge digesters and 3 sludge concentrated tanks in the west part of the plant had vanished compared the data acquired in March and September .The results were consistent with the Google Earth images during the similar period .%通过文献调研和数据搜集构建高碑店污水处理厂的基本信息库,利用GF-1/GF-2等高分辨率卫星遥感数据对2015年高碑店污水处理厂的运行状况进行动态监测.结果表明:GF-1号影像显示2015年2月16日和3月25日污水处理厂均有1个二沉池有藻类分布,疑似未正常投入使用;GF-2号影像显示9月2日污水处理厂有5个二沉池和部分曝气池的廊道有藻类分布,疑似未正常投入使用;3月和9月数据对比发现,西侧的8个污泥消化罐和3个污泥浓缩池均消失.该结果与临近时期的Google Earth影像显示情况相一致.
