| 摘 要： | 主要探讨臭氧对煤气废水生物处理出水的预氧化效果及其对后续生物处理过程的强化作用。实验表明,臭氧对废水的色度去除很有效,<160mg/L的臭氧投量就可去除90%的色度,废水pH较小时色度去除效果较好;臭氧氧化对废水残留COD(化学需氧量)有一定的去除作用,不同的pH条件下去除率有差异,总体每毫克臭氧可去除0.44mg￣0.64mg的COD;臭氧氧化对废水NH3-N的去除效果不明显;臭氧有效投加量为240mg/L时,废水COD去除率降低,氧化后出水BOD(生化需氧量)上升,有利于后续生物处理。

| Abstract: | This research mainly focuses on the characteristics of wastewater under lower ozone doses. Experimental results show that although pH value of wastewater affects the effectiveness, the color of wastewater could be removed by low ozone dose (<160mg/L). It is indicated that 0.44~0.64mg of COD can be removed by one milligram of O3 and low ozone dose cannot removal NH3-N whether the pH value of the wastewater is 7 or 9. Data of BOD, COD and pH show that 240mg/L O3 is the best dose for the subsequent bio-treatment. |
