| 摘 要： | 针对反硝化聚磷菌的生物学特性,设计并制作了硝化反硝化除磷气升式环流生物膜反应器,并就其对生活污水的脱氮、脱碳和除磷过程进行了试验.试验结果表明,当进水COD为309.8 mg/L、NH4 -N为116.0 mg/L、PO34-P为10.5 mg/L时,它们的去除率分别为95.3%、94.6%和73.1%.通过间歇试验表明该反应器可以实现反硝化除磷.

| Abstract: | A airlift loop sequencing batch biofilm reactor was developed to enhance biological nitrogen and phosphorus removal by integrating nitrification and denitrifying dephosphatation.Long term experiment was carried out on synthetic wastewater.The results showed that when the mean concentrations of influent were about COD 309.8(mg/L),NH~+_4-N(116.0) mg/L and PO~(3-)_4-P 10.5 mg/L,and the removal efficiencies of them were about 95.3%,(94.6%) and 73.1%,respectively.Batch experiments show that denitrifying dephosphatation could occur in the reactor. |
