曝气量对好氧填料床处理农家乐生活污水的影响

Influence of Different Aeration Rates on “Farm Fun” Sewage Treatment in Aerobic Packed Bed

考察了曝气量在0．1～0．5m^3／h条件下，好氧填料床对农家乐生活污水处理效果的影响；试验结果表明，CODcr和NH3-N的去除效果随曝气强度的增加呈先上升后下降的趋势，而曝气量的变化对SS和动植物油的去除效果无显著影响；在较低曝气量0．25m^3／h情况下，出水CODcr、NH3-N、SS、动植物油的去除率分别为：86％、86．6％、87％、91％，出水均可达标排放。

The capacity of ＂Farm Fun＂ Sewage Treatment in aerobic packed bed was examined under different aeration intensities （0. 1 - 0.5 m3/h）. The results showed that CODor and NH3-N removal rate increased with the increasing of aeration intensity, but excessive aeration intensity reduced CODer and NH3-N removal effect. SS and the animal and vegetable oils removal rate was not significantly affected with the aeration rate change .While in the lower aeration rate which was 0.25 m3/h, the CODer, NH3-N , SS and the animal and vegetable oils removal rate was 86%, 86.6%, 87% ,91%respectively, which reach discharge
