摘　　要：在连续流完全混合反应器(CSTR)中,采用不同进水方式,以乙酸钠作为碳源配制的人工配水作为原水,对好氧颗粒污泥的运行效能进行了试验研究。研究表明,采用不同进水方式运行的2个反应器在颗粒污泥出现后,运行效能差别不大;好氧颗粒污泥反应器运行高效稳定,在水力停留时间为1.5h、COD容积负荷为1.0kg/(m3·d)的条件下,对COD、TP、NH4+-N和TN的去除率分别为90%、85%、95%和60%,并具有明显的脱氮除磷效果;反应器中存在同步硝化反硝化现象。The laboratory-scale study was carried out for cultivating aerobic granule sludge in a continuous-flow completely stirred tank reactor （CSTR）. The synthetic raw water, with acetic acid as the carbon source, was injected in CSTR using of 2 different influent patterns. The effects of influent pattern on operational performance of CSTR and sludge granulation were investigated. The results showed that two reactors （CSTRI and CSTR2） presented little difference in sludge granulation. However, the operational performance of two reactors was similar after sludge granulation. Under the conditions of hydraulic retention tittle of 1.5 h and organic loading rate of 1.0 kg/（m^3 · d）, both reactors operated stably and efficiently, and removal rate of COD, TP, NH4^＋-N and TN were 90%, 85%, 95%and 60%. Simultaneous nitrification and denitrification （SND） was also found in the two reactors.
