| 中文摘要 |
| 阐述了ABR处理含盐变性淀粉废水的启动过程和颗粒污泥的特征；提出了ABR处理变性淀粉废水的最佳工况；对ABR处理含盐废水的运行性能进行了研究.结果表明，同时提高有机负荷和盐浓度进行污泥驯化具有可行性，能够培养出耐低盐的颗粒污泥.在氯离子浓度为8 500 mg/Ｌ，含盐量为1.6％，经过驯化，污泥能够正常降解废水中的有机物，COD去除率在85％以上.试验用变性淀粉废水的COD浓度为12 640 mg/Ｌ，最佳HRT为48 h，此时COD去除率85.9％.氯离子浓度的突然急剧降低比突然急剧增高对系统污泥微生物的影响更大.系统能够忍受氯离子浓度从8 500 mg/Ｌ直接升到12 500 mg/Ｌ和从8 500 mg/Ｌ直接降低到4 500 mg/Ｌ的变化，且抗氯离子浓度突然升高的能力比抗氯离子浓度突然降低的能力要强.ABR系统能够处理氯离子浓度在15 000 mg/Ｌ以下，含盐量在2.5％左右的废水. |
| 英文摘要 |
| The present study reports the start-up of treating metamorphic amylum production wastewater by anaerobic baffled reactor (ABR) and the bio-chemical features of granular sludge. The optimal conditions in treatment of the metamorphic amylum production wastewater were proposed, and the running performance in treating salt-containing wastewater was studied. Our results show that the common anaerobic activated sludge can be acclimated by increasing the organic loading and salt-concentration at the same time, and the granular sludge tolerant to low salt can be achieved by the acclimation. When chloric ion was 8 500 mg/Ｌ and salinity was 1.6％，the anaerobic activated sludge could degrade organic materials normally in the wastewater after the acclimation, and the COD removal is over 85％. When the concentration of metamorphic amylum production wastewater in the experiment was 12 640 mg/Ｌ and the optimal hydraulic retention time was 48 h， the removal efficiency of COD was 85.9%. Effect of sharp decrease of chloric ion concentration on sludge microorganism is larger than that of the sharp increase in the system. The system can endure the change of chloric ion concentration by increasing from 8 500 mg/Ｌ to 12 500 mg/Ｌ or decreasing from 8 500 mg/Ｌ to 4 500 mg/Ｌ, and it is more tolerant to the sudden increase than that of the sudden decrease of chloric ion concentration. The ABR system can treat the wastewater with chloric ion below 15 000 mg/Ｌ and salinity of about 2.5％. |
