摘要
在连续流完全混合反应器(CSTR)中,采用不同进水方式,在沉淀时间为1.5 h,容积负荷分别为1、1.5、2、3、4 kgCODCr./(m3.d)时,对好氧颗粒污泥反应器的运行效能进行了试验研究。研究结果表明,采用重力流进水方式的反应器运行效能优;在沉淀时间为1.5 h时,两反应器对污染物的去除负荷随容积负荷的上升而上升;在沉淀时间为1.5 h、有机负荷为1.5 kg CODCr/(m3.d)的条件下,两反应器对CODCr、TP、NH4+-N的去除率可达到最高。
The laboratory-scale study was carried out on the operational performance of aerobic granule sludge in a continuous-flow completely stirred tank reactor(CSTR) when the settling time was 1.5 h and the volumetric organic loading rate was 1,1.5,2,3,4 kgCODCr/(m3.d) by using different influent patterns.The results showed that the operational performance of the reactor with gravity flow was excellent;the removal profile of volumetric organic loading rate increased with the increasing of volumetric organic loading rate in both reactors when the settling time was 1.5 h;the highest removal profile of CODCr,TP,NH4+-N in both reactors could be obtained when the settling time was 1.5 h and the volumetric organic loading rate was 1.5 kgCODCr /(m3.d).
