不同MLSS对低温低碳氮比污水处理效果的影响
Effects of Different MLSS on Sewage Treatment Efficiency by Low Temperature and Low C/N
摘要
Abstract
In the present study, we investigated active sludge acclimated by low temperature and low C/N on aerobic conditions in SBR reactor. After 30 days of acclimatization, the sludge transformed from deep black and unconsolidated into light-coloured and flocculent state. On completion of active sludge acclimatization, we also investigated the removal rate of different density MLSS and the dynamics of substrate degradation. These results show that the outflowed water quality is better than others, the removal rate of COD is 97.1 % and the removal rate of total nitrogen is 63.1 % on condition that the COD and NH_4-N concentration of inflowed water are determined and the MLSS is 3-4 g/L, and the degradation process of ammonium nitrogen accords with the Monod first order dynamic equations S_e/S_0 = e~(-KXt), R~2 = - 0.954 8 - -0.985 6.关键词
