摘要
通过中试除藻试验,研究了臭氧活性炭深度处理工艺的除藻效能。结果表明,经过预臭 氧化和常规工艺处理后,深度处理工艺可再去除67％的含藻量。工艺参数:臭氧投加量2 mg／L,接 触时间15 min,活性炭滤池滤速10 m／h,停留时间12 min。探讨了预臭氧化和深度处理两种组合工 艺的除藻机理和影响因素。
Pilot experiments were conducted to investigate the algae removal efficiency of ozone- GAC process, one of advanced drinking water treatments. Results showed that for the output water of routine water purification with preozonation, an additional removal of algae of 67 % could be obtained by ozone-GAC process in case when ozone dosage was 2 mg/L, ozonation contact time was 15 min. , GAC filtration velocity was 10 m/h and HRT was 12 min. The mechanism and the affecting factors of algae removal by this combined processes of twice ozonation were also discussed in this paper, these might be beneficial to use this combined processes effectively and safety for algae removal.
