摘　　要：以上海市白龙港城市污水厂初沉池污水为进水,构建A2/O试验系统。调节试验系统有机负荷(F/M),并分析负荷对A2/O工艺脱氮的影响。结果表明,COD去除最佳F/M范围为0.14～0.28gBOD5·gMLSS-1·d-1;BOD5去除最佳F/M范围为0.14～0.22gBOD5·gMLSS-1·d-1;反硝化最佳F/M范围为0.13～0.23gBOD5·gMLSS-1·d-1;硝化最佳F/M范围为0.14～0.28gBOD5·gMLSS-1·d-1。根据分析,F/M介于0.14～0.22gBOD5·gMLSS-1·d-1之间时,A2/O工艺脱氮效果最佳。The original water of Bailonggung wastewater treatment plant was used to construct A^2/O process,The influence of F/M on nitrogen removal was studied by regulating the BOD5 loading （F/M） of A2/O process. The results showed that the best range of F/M for COD remove was 0.15-0.28 gBOD5·gMLSS^-1·d^-1; the best range of F/M for BOD5 remove was 0.14-0.22 gBOD5·gMLSS^-1·d^-1;the best range of F/M for denitriflcation was 0.13 0.23 gBOD5·gMLSS^-1·d^-1. the best range of F/M for nitrification was 0.14-0.28 gBOD5·gMLSS^-1·d^-1. According the analyse,the best range of F/M for the A^2/O system was 0.14-0.22 gBOD5·gMLSS^-1·d^-1.
