| 摘 要： | 在实验室条件下研究了传统水处理工艺和粉末活性炭吸附、吹脱及臭氧氧化等几种常见应急净水技术对乙醛的处理效果,发现其对水中乙醛的控制效果不佳;活性炭对乙醛吸附效果不佳,导致滤池穿透时间极短,新炭也仅为10 h左右,不足以应对乙醛污染.微生物对乙醛降解作用显著,驯化后的生物活性炭滤池(BAC)13 min内可将水中1.5 mg/L的乙醛降低到标准限值0.05 mg/L以下.水厂在用活性炭滤池中的微生物菌群实验条件下驯化时间约为4～30 h,原有菌落成熟且稳定的活性炭需要的驯化、调整时间反而更长.通过抑制颗粒活性炭表面原微生物活性或人工投加驯化菌种可有效地将驯化时间从30 h左右缩短至4 h以下. |

| Abstract: | The effect of acetaldehyde removal by several kinds of water-treating technologies is experienced in laboratory and the results reveal that traditional water-treating processes have hardly any useful results and the absorption of GAC does no better either for its efficiency depending on the GAC service time greatly and with a very short leakage time.However,the micro-biological degradation process in the BAC filter can consume more than 95% acetaldehyde in 13 minutes when the biomass has been fully acclimat... |
