- 摘要:
- 为探究扬水曝气技术在调水型水库水质改善中的应用效果,在茜坑水库扬水曝气强化生物改善工程运行前、后一个月(2021年6月28日—9月2日)进行了全库水质监测。结果显示,扬水曝气系统成功提升了水体含氧量,提高了水体流动性,强化了水库自净能力。作用范围内水体热分层完全消失,底层溶解氧升高到6 mg/L以上,藻密度降低到5×106 cells/L且优势种由蓝藻转变为硅藻,铁和锰释放得到显著抑制,TP削减率增加了21%。此外,运行成本最多仅为0.02元/m3,远低于水厂处理成本。
- Abstract:
- To explore the application performance of water-lifting aeration (WLA) technology in water quality improvement of water diversion reservoirs, the water quality of the whole Xikeng reservoir was monitored before and after the operation of WLA enhanced biological improvement project from June 28 to September 2, 2021. The WLA system successfully increased the oxygen content of the water body, improved the fluidity of the water body and strengthened the self-purification capacity of the reservoir. The water thermal stratification disappeared completely, the bottom dissolved oxygen increased to more than 6 mg/L, the algae density decreased to 5×106 cells/L, and the dominant species changed from cyanobacteria to diatoms. The release of iron and manganese was significantly inhibited, and the TP reduction rate increased by 21%. In addition, the operating cost was 0.02 yuan/m3 at most, much lower than the treatment cost of waterworks.
