摘　　要：采用配制的废水对内循环厌氧反应器进行了小试研究,考察了其运行状况和影响运行的特征参数。研究表明,内循环厌氧反应器处理的最高有机负荷为45.26kg[COD]/(m3.d);当控制反应器的碱度(以CaCO3计)为1000～5000mg/L,出水pH值在7.0左右,VFA的质量浓度为800mg/L以下时,可以使反应器正常运行。A small-scale experiment on intemal circulation anaerobic reactor was studied with prepared water as influent wastewater, the running state and the characteristic parameters that influence the reactor＇s running were investigated. The results of the test showed that, the highest organic loading rate of the internal circulation reactor was 45.26 kg [COD ]/（m^3·d）; Under the condition that alkalinity （calculated by CaCO3） was controlled at the range of 1 000 - 5 000 mg/L, the pH value was about 7.0, the mass concentration of VFA was below 800 mg/L, the reactor could run normally.
