中文摘要	对中国南方某城市三座重要城市地表供水和原水调蓄水库库心溶解氧的纵向分布进行了为期5个月的调查,发现各水库水体底层溶解氧含量均低于2 mg/L,处于缺氧甚至厌氧状态;同时对南方某高校人工湖湖心溶解氧进行监测,结果表明:湖心水深2.5 m左右,底层溶解氧含量低至4 mg/L。根据调查结果设计了一种用于城市地表水体底层低氧现象应急修复的强制水体循环装置,选择人工湖水体进行了中试试验,验证其效果后将其用于实际工程案例,进一步验证了其能够快速提高水体溶解氧含量、改善水质,是应用于地表水体应急处理的有效技术。; A five months investigation about dissolved oxygen vertical distribution was carried out in three important reservoirs in a city in southern China. The results showed that the bottom dissolved oxygen concentration of the three reservoirs are all lower than 2 mg /L,in anaerobic or anoxia state. At the same time,the investigation was carried out at the artificial lake in a university in southern China. The results showed that at the depth of 2. 5 m or so in lake center,the underlying dissolved oxygen content is as low as 4 mg /L. According to the survey,a forced water circulation device was designed,which can be used for urban surface water emergency repairing. Pilot test study about the device was carried out in an artificial lake and then the device was used in an actual project. All the results finally proved that it is an effective technique for urban surface water in improving dissolved oxygen concentration and water quality.
