摘　　要：培养厌氧颗粒污泥的自制反应器进水为养猪废水,进行不同惰性载体对厌氧颗粒污泥形成影响的对比实验。结果表明,添加大孔型阳离子交换树脂的反应器培养时间为39d,COD去除率达到80%,并出现粒径为2.50~3.00mm的大颗粒污泥,产甲烷量为9.75mL CH4·（gVSS·d）-1,与添加聚合铝和粉煤灰的反应器相比,产甲烷菌活性显著强;添加惰性载体与未添加载体反应器相比,培养时间缩短20%~45%,厌氧颗粒污泥活性相差14.00%±0.10%;参考Richards模型进行产甲烷量和反应器培养过程中出水COD建模,发现实验数据和模型数据对比偏差在0.50%±0.01%。The aim of this study is to investigate the effect of different inert carrier on the formation of anaerobic granular sludge, which used swine wastewater as a cultivation of anaerobic granular sludge self- made reactor flooding water. The results show that anaerobic reactor which was dosing macroporous type ion exchange resin cultivated granular sludge using 39 d and particle size was 2.50 to 3.00 mm, effluent water COD removal efficiency achieving 80%, methane-producing capacity achieving 9. 75 mL CH4 · （g VSS · d）-1, comparing with the anaerobic reactor which was dosing polymerization aluminum and fly ash had higher methanogenic activity, comparing with the anaerobic reactor which was not dosing any carrier shorten cultivation time about 20%-45% and granular sludge activity improved 14.00%±0. 10%. Referred to Richards model found relationship of methane production and effluent water COD and established mathematical model. Analysis of experimental data and model data deviation was within 0. 50% ±0. 01%.
