摘要:
为确定环境差异对磷去除机制影响,利用组合塘-湿地生态处理系统中各单元环境与磷形态分布的差异,分析各单元磷的主导去除机制及其对底泥和水体中磷迁移过程的影响。结果表明:悬浮磷沉积、溶解无机磷的吸附/络合和悬浮磷的截滤依次为各单元磷的主导去除机制。磷主导去除机制的差异决定了各单元底泥中磷分布遵循一定的规律性和特殊性。此外,低温期悬浮磷的沉积作用除磷效率高;高温期溶解无机磷的吸收/络合作用除磷效率高。因而,水环境差异对生态处理系统中磷去除规律影响明显。
Abstract:
In order to determine the influence of environmental variations on phosphorus removal mechanisms in a combined pond-wet land system, the dominant removal mechanisms of phosphorus in different treatment unit and their influence on phosphate transformation between sediment and water column were invest igated through analyzing the differences of phosphorus fractionation with water conditions. The results show that the precipitation of particulate phosphorous, the adsorption/ complexation of dissolved inorganic phosphorous and the filtration of particulate phosphorous were the dominant removal mechanisms of different units in turn. Variations of dominant removal mechanisms produced there were some similarities and differences exist ing in sedimentary phosphorous fract ionation in each unit. Additionally, it was the precipitat ion process of suspended phosphorus that played a relative important role in phosphorus removal in cold periods, and that was adsorption/ complexation of dissolved inorganic phosphorus in warm periods. Therefore, environmental variations evidently affects the phosphorus removal performance in the ecological treatment system.
