| 摘 要： | 采用日本菊池环保株式会社生产的新型TCRI-17微气泡气浮装置混凝气浮处理北京某富营养化景观水体的含藻废水，其结果表明，当混凝剂用量分别为PAC 40 mg/L和PAM 2 mg/L，混凝2 min, 气浮2 min时，SS和COD去除率分别达到98.4%和85.7%。与混凝沉降相比，可减少PAC用量1/3，且节省处理时间。由于微小气泡停留时间长，气浮效率高，且有增加水中溶解氧的作用，可促进水体的净化，具有较强的技术优势。 |

| Abstract: | Based on coagulation-micro bubble air flotation processes, this study applied micro-bubble air floatation equipment TCRI-17 to treat algae-laden wastewater in Beijing conference center. The results show that when the combination coagulant is used and the consumption of PAC is 40 mg/L and PAM is 2 mg/L, and the process time is 2 min, the removal rates of SS and COD are 98.4% and 85.7%, respectively. Comparing with the coagulation sedimentation process, the consumption of PAC is reduced by 1/3 and process time is saved greatly by this process. Because the staying time and the floatation efficiency are improved, and DO in water are increased, it could advance purification of water and have significant technical advantages. |
