| 中文摘要 |
| 利用室内大型土柱对RI系统中微量有机化合物氯仿、四氯化碳、三氯乙烯及苯、甲苯的净化过程进行了模拟研究。结果表明,系统对3种氯代脂肪烃具有很好的净化效果,其浓度可从2000-6000μg/L降至100μg/L以下。系统对苯及甲苯的净化则与淹水时间有关,滩水初期净化效果良好,其浓度可从进水时1000-1700μg/L降至100M/L以下,但随着淹水时间延续,净化效果变基,直至出水浓度与进水浓度基本相同。 |
| 英文摘要 |
| The removal of some-organic Pollutants trichloromethane,tetrachloromethane. trichlorothylene,benzene and toluene in rapid infiltration treatment system of waste water have been simulated in large scale soil colums.The thai kinds of chlorinated aliphatic hydrocarbons were taping removed from influent concentration of 2000-6000μg/L to effluent concentration of less than 100 μg/L.The removal effects of benzene and toluene depended on the flailing time. In the early part of finding Period,bemene and toluene could be removed rapidly from influent concentration of 1000-1700 μg/L to effluent concentration of less than 100 μg/L.With the increase of flooding time, the removal effect became lower and lower until the effluent concentration of benzene and toluene almost equal to the infiuent concentration. |
