摘要
为确定生物炭对生活污水的净化效果,往模拟废水中添加稻壳生物炭,研究了生物炭添加量、pH值、温度和时间对模拟沼液的化学需氧量(COD)、总氮(TN)和总磷(TP)的去除效果。研究结果显示,适宜的净化条件为:生物炭用量为2 g/L,温度为30℃,pH为6. 8,时间4h。在此条件下,模拟污水的最大COD、TN和TP的去除率分别为43. 44%±1. 12%、44. 51%±0. 59%和46. 51%±0. 95%。本研究结果对未来应用生物炭对污水的净化提供了重要的理论参考。
In order to explore the effect of biochar on the removal of pollutants in domestic wastewater,rice husk biochar was added into domestic wastewater,the effects of dosage,pH,temperature and time on removal efficiency of chemical oxygen demand( COD),total nitrogen( TN) and total phosphorus( TP) in domestic wastewater were discussed. The results showed that the maximum COD,TN and TP removal efficiencies of synthetically domestic wastewater were 43. 44%±1. 12%,44. 51%±0. 59% and 46. 51%±0. 95%,respectively at the biochar amount of 2 g/L,the temperature of 30 ℃,pH of 6. 8,and the time of 4 h. This will provide a theoretical basis for the future study of biochar to remove pollutants from sewage.
