| 摘 要： | 采用无纺布作为一种新型悬浮填料,探索无纺布填料处理污水的适用条件、运行参数及降解机理.研究认为不同容积负荷应采取不同的填料投配率:当CODCr容积负荷低于1.2kg/(m3·d)时,取填料投配率为20%;当CODCr容积负荷在1.2～2.0kg/(m3·d)之间时,取填料投配率为38%;当CODCr容积负荷达2.0 kg/(m3·d)以上时,取填料投配率为29%模型结果表明,附着微生物降解有机物的规律可用Monod方程的形式描述.

| Abstract: | Non-woven fabric was adopted as a new kind of suspended media. Adapting condition and operation parameters and biodegradation mechanism using non-woven fabric media in wastewater treatment were studied. The result of experiment shows that different CODCr volumetric load should take different media volume. When CODCr volume load was lower than 1.2 kg/(m3.d), the volume ratio of media to reactor should be 20%; the CODCr volume load between 1.2-2.0 kg/(m3.d), the volume radio of media to reactor 38%; the CODCr volume load was larger 2.0 kg/(m3.d), the volume radio of media to reactor 29%. The result of the model shows that the biodegradation rule of pollutant can be described by the format of Monod Equation. |
