物化法处理醇胺类污染地下水的实验分析

采用臭氧、芬顿试剂、活性炭以及组合工艺对醇胺类污染地下水(COD 2600 mg/L,氨氮100 mg/L)的COD和氨氮进行氧化分解(和吸附)实验,考察不同物化法对COD和氨氮的去除效果。结果表明,活性炭(20g)+芬顿试剂(n(Fe^(2+)):n(H_2O_2)=1:2,分4次投加)组合工艺对该污染地下水处理效果最佳,COD 315 mg/L,氨氮33 mg/L,达到上海市地方标准《污水排入城镇下水道水质标准》(DB 31/445-2009)排放标准,为醇胺类污染地下水提供可靠实用的处理方法。

A laboratory experiment was conducted to study the decomposition （and absorption） of the groundwater （COD 2 600mg/L,NH4＋-N 100 mg/L）polluted by alcohol amine compounds under the effects of ozone, fenton reagent, activated carbon and the Combination processes, aimed to obtain the removal efficiency of COD and NH4＋-N by different physical and chemical methods. The result showed that, the best of removal efficiency was the combina- tion process of activated carbon （ 20 g） and fenton reagent （ n （ Fe^2＋） ： n （H202） = 1：2, dosing for 4 times ）, COD 315 mg/ L, NH4＋-N 33 mg/L, and achieved to dards＂ （ DB 31/445-2009）, provided Shanghai standards ＂Sewage discharged a reliable and practical treatment method into urban sewage water quality stan- for the polluted groundwater.
