摘要
研究了白泥含量为20%的混合土对COD和氨氮的去除效果及影响因素。结果表明,进水COD负荷在36.14~144.58g/（m2.d）,水力负荷15.92~191.08L/（m2.d）之间变化时,混合土对COD去除率一般为60%,对氨氮的去除率在90%以上。水力负荷和污染物负荷对渗滤液中污染物的去除率有较大的影响,水力负荷与污染物的去除率呈负相关,污染物浓度负荷与污染物的去除率呈正相关,且污染物的浓度负荷影响较大。
The removal rates and influence factors of COD and ammonia-nitrogen dealt by the mixed soil which contained 20% white mud was invested.The result shows that the removal of COD is above 60%,the removal of ammonia-nitrogen is above 90% when hydraulic loading change from 15.92 L/（m2.d） to 191.08L/（m2.d）,COD loading change from 36.14 g/（m2.d） to 144.58g/（m2.d）.The removal of COD and ammonia-nitrogen are positively correlated with the concentration,while negatively correlated with the hydraulic load.
