| 摘 要： | 研究了三种不同基质组合对生活污水中磷的去除效果。结果表明,柱1(天然蛭石-红壤-石灰石)对总磷和正磷酸盐的处理效果最好,去除率的均值分别达到了83%和85%,总磷出水浓度均值达到了污水综合排放标准中的Ⅰ类标准。同一基质组合不同污水去磷的去除效果研究表明,单一含P溶液的系统比生活污水的系统除磷效果好,主要原因可能在于离子竞争吸附及pH值的差异。

| Abstract: | Effect of three types of substrate combinations for removal of phosphorus from household wastewater was studied. Results showed that system 1 of natural vermiculite-red soil-limestone had the highest removal efficiency for TP and PO43-P with average removal efficiency of 83% and 85% respectively. Effluent TP concentration in system 1 met Class I of national discharge standard. Removal efficiency of phosphorus in P containing solution is higher than that in household wastewater in the same substrate combination system, which may be accounted for by the effect of low pH and adsorption competition due to presence of different ionic species in household wastewater. |
