摘　　要：为考察腐殖生态基填料对活性污泥中β-葡萄糖苷酶和脂肪酶活性的影响,在常温下将内置和外置腐殖生态基填料的SBR工艺(HS-SBR)与传统SBR工艺(cSBR)进行对比研究,探讨不同反应器中β-葡萄糖苷酶和脂肪酶活性变化规律,以期从酶学角度为腐殖生态基的推广和使用提供更多的理论基础。研究表明:内置、外置HS-SBR反应器内β-葡萄糖苷酶的活性在整个运行过程中均高于c SBR反应器,其中内置、外置HS-SBR反应器中β-葡萄糖苷酶在运行过程中的平均活性分别比c SBR反应器高出2.58%和7.08%;内置、外置HS-SBR反应器内脂肪酶的活性在整个运行过程中均高于c SBR反应器,其中内置、外置HS-SBR反应器中脂肪酶在运行过程中的平均活性分别比c SBR反应器高出23.22%和32.79%。总体来看,添加腐殖生态基可以提高活性污泥中β-葡萄糖苷酶和脂肪酶的活性,且外置腐殖生态基填料的方式对β-葡萄糖苷酶和脂肪酶活性的强化作用更为明显。In order to investigate the effect of humic soil on the activity of β-glucosidase and lipase in activated sludge, the SBR process with internal and external humic soil(HS-SBR) was compared with the conventional SBR process(cSBR) at normal atmospheric temperature. The change rule of β-glucosidase and lipase activity in different reactors was discussed, in order to provide more theories for promotion and use of the humic soil. The results showed that the activity of β-glucosidase in the internal and external HS-SBR reactors was higher than that in the cSBR reactors in the whole operation process, and the average activity of β-glucosidase in the internal and external HS-SBR reactors was higher than that in the cSBR reactors by 2.58% and 7.08%, respectively. The activity of lipase in the internal and external HS-SBR reactors was higher than that in the cSBR reactors in the whole operation process, and the average activity of lipase in the internal and external HS-SBR reactors was higher than that in cSBR reactor by 23.22% and 32.79%, respectively. In general, humic soil improved the activity of β-glucosidase and lipase in activated sludge, and the way of external humic soil enhanced the activity of β-glucosidase and lipase more obviously.
