摘要
以河沙、页岩、石灰石等3种重庆常见基质为人工湿地填料,探讨了磷负荷和有机负荷对基质动态除磷效果的影响。结果表明,在同等磷负荷和有机负荷情况下,3种填料的去除效果依次为石灰岩(河沙(页岩;有机负荷对各填料除磷有重要的影响,随着有机负荷的增加,填料除磷率均有不同程度的降低。有机负荷对石灰岩除磷的影响较大,对河沙除磷的影响相对较小。
Three kinds of materials that are common in Chongqing,i.e.,river sands,shale and limestone were used as packing medium for constructed wetland.The effects of phosphorus loading and organic loading on dynamic adsorption phosphorus were studied.The results showed that at same loading rates of phosphorus and organic,the phosphorus removal of the three materials were observed as limestone river sands shale.Organic loading affected removal of phosphorus significantly.Actually phosphorus removal decreased in different rate with increasing of organic loading.Organic loading affected phosphorus removal significantly for limestone as packing material but relatively lower for river sands.
