| 中文摘要 |
| 在水处理过程中投加臭氧,可提高饮用水的可生物降解性.臭氧氧化后继的生物过滤,可以减少水中可生物降解有机物数量,提高饮用水的生物稳定性.试验表明,臭氧投加量2～8mg/L可使AOC-P17,AOC-NOX和BDOC分别增加20.9%～85.5%,42.1%～158.2%和21.4%～84.4%.臭氧投加量为3mg/L时,AOC和BDOC增加得最多,即3mg/L的臭氧投量为最佳投加剂量.生物活性炭滤柱(BAC)出水AOC浓度(乙酸碳)均低于50μg/L,在35.9～46.6μg/L之间,属于生物稳定性水质. |
| 英文摘要 |
| The ozonation can increase biodegradability of water and the biofilter after ozonation can increase biostability of water.The result shows that with different doses of ozone between 2 and 8 mg/L,ozonation can increase AOC-P17, AOC-NOX and BDOC by 20.9%～85.5%,42.1%～158.2% and 21.4%～84.4%,respectively.The optimum ozone dose for maximum AOC and BDOC formation is 3 mg/L.In the test,the AOC of effluent from BAC is lower than 50μg/L(acetate-C).The AOC concentration is between 35.9 and 46.6μg/L(acetate-C),and the effluent belongs to biostability. |
