摘　　要：为研究序批间歇式(SBR)反应器中好氧颗粒污泥处理汽车涂装废水的可行性,采用以生活污水培养出的好氧颗粒污泥作为接种体,逐步加入汽车涂装废水驯化,考察被驯化的颗粒污泥的形态、理化性质以及反应器内污染物的去除效果。结果表明:驯化5周后的颗粒污泥未有解体,结构更致密,平均粒径可达到1.5 mm,呈白色,MLSS为8000 mg/L,SVI30值为28 mL/g,其沉降性能、生物量都提高。反应器运行至45 d左右,除污性能明显且稳定,COD、NH4+-N、PO43--P的出水浓度保持在100 mg/L、10 mg/L、1.0 mg/L以下,均达到GB8978—1996《污水综合排放标准》二级标准,保持了良好的污染物同步去除效果。In order to study the feasibility of coating wastewater treatment by aerobic granular sludge in SBR, aerobic granular sludge cultivated in domestic wastewater was used as inoculum and gradually acclimated by the coating wastewater. In this way, the shape, physicochemical properties and pollutant removal ability of acclimated granular sludge were observed. The results showed that five weeks later, the acclimated granular didn＇t disintegrate but in a more compact structure, white color with an average diameter 1.5 mm, MLSS 8000 mg/L and SVI30 28 rag/L, which represented that both the settling performance and the biomass had been improved. When the reactor operated about 45 days, the pollutant removal ability was found to be in apparent and stable state with effluent concentration of COD, NHa＋-N, PO43- -P below 100 mg/L, 10 mg/L, 1.0 mg/L, which achieved the secondary standard of ＂Integrated Wastewater Discharge Standard＂ （GB 8978--1996） as well as the good pollutant removal effect synchronization.
