Abstract

Abstract:

The A²/O-BAF two-sludge system was used to investigate the recovery of pollutant removal performance of activated sludge had been deposited for two month, when V_anaerobic: V_hypoxia: V_aerobic=3:5:2 and 1:3:1. The results showed that the two methods had little effect on the removal of COD and NH₄⁺-N. V_anaerobic: V_hypoxia: V_aerobic=3:5:2 was more conducive to the recovery of the removal performance of TN and PO₄^3--P, and the TN and PO₄^3--P concentration of the effluent reached 14.20 mg/L and 0.42 mg/L on the 7th and 4th day respectively. The removal rates were 80.47% and 92.02%. Fitting equation analysis of anaerobic phosphorus release and anoxic/aerobic phosphorus absorption test results showed that the anaerobic release of V_anaerobic: V_hypoxia: V_aerobic=3:5:2 and the phosphorus absorption of hypoxia were higher, and the phosphorus absorption rate was faster. The V_anaerobic: V_hypoxia: V_aerobic=3:5:2 was more conducive to the rapid secondary start of the A²/O-BAF system.

Key words: A²/O-BAF two-sludge system, pool capacity ratio, secondary start-up

摘要：

采用A²/O-BAF双污泥系统，考察池容比（V_厌氧：V_缺氧：V_好氧）分别为3：5：2和1：3：1时对搁置2个月的活性污泥去除污染物性能的恢复情况。结果表明，2种池容比对COD和NH₄⁺-N的去除性能恢复影响较小。V_厌氧：V_缺氧：V_好氧=3：5：2更有利于TN和PO₄^3--P的去除性能恢复，其出水TN和PO₄^3--P在第7天和第4天分别达到14.20 mg/L和0.42 mg/L，TN、PO₄^3--P去除率分别为80.47%、92.02%。拟合方程分析厌氧释磷和缺/好氧吸磷的小试结果表明：V_厌氧：V_缺氧：V_好氧=3：5：2的厌氧释磷量和缺氧吸磷量更高，且吸磷速率更快。即V_厌氧：V_缺氧：V_好氧=3：5：2更有利于A²/O-BAF系统的二次启动。
