| 摘 要： | 已有的研究证明,固定化光合细菌对污水中有机污染物的处理效果优于分散的光合细菌。本文利用从海洋中筛选分离的海洋光合细菌,以海藻酸钠为海洋光合细菌固定化基质,蒙脱石纳米材料为固定化基质添加剂,研究了固定化海洋光合细菌处理生活污水的效用。研究表明,使用海藻酸钠为基质的固定化海洋光合细菌和以蒙脱石纳米材料为添加剂的固定化海洋光合细菌对生活污水中的氮、磷均具有一定的处理效率,前者对氨氮、总氮和总磷的处理率最高分别为87.68%,70.95%和71.90%。添加蒙脱石纳米材料为添加剂后的固定化海洋光合细菌的去除率则分别为91.30%,73.51%和84.88%。添加有纳米蒙脱石的固定化海洋光合细菌比没有添加的固定化海洋光合细菌的去除率高10%左右,而且两者对氮、磷的处理速率也有大幅度的提高,在12h左右即可将处理效率提高到60%~80%。在高浓度有机废水和高氮磷浓度的废水处理中具有较强优势,同时由于该方法使用固定化光合细菌的量较少,回收简单,对污水处理中的污泥减量化也有一定的贡献。

| Abstract: | Some researches have proved that it is better to treat organic pollutants in wastewater using immobilized PSBs than PSBs.In this research,the treatment of domestic sewage by two kinds of immobilized marine PSBs isolated from sea water around Zhanqiao,Qingdao was studied,one was sodium alginate immobilized marine PSBs and the other was sodium alginate immobilized marine PSBs with nano-montmorillonite as additive.The results showed that both the two kinds of PSBs were useful to the denitrifiction and phosphorus removal.The removal rates of NH_3-N, TN and TP of the former were 87.68%,70.95% and 71.90%,respectively and the removal rates of NH_3N,TN and TP of the latter were 91.30%,73.51% and 84.88%,respectively.The results also showed that the removal rate of imobilized PSBs with nano-montmorillonite was 10% higher than that of immobilized PSBs without nano-montmorillonite.And the removal speed was also accelerated by both immobilized PSBs;within 12 hours,the removal rate was improved to 60%~80%.This method was better in treating high concentration organic wastewater,and because only a small amount of immobilized PSBs was used and it was easy to be retrieved,it contributed to sludge decrement as well. |
