【摘要】 针对厌氧反应器的布水系统容易产生短流,在反应器内造成死区,从而减少反应器的有效容积的缺点,研究开发了外循环厌氧(EC)反应器并进行处理啤酒废水的试验研究．结果表明,外循环厌氧(EC)反应器采用旋流配水装置,布水均匀,存在明显的颗粒污泥区和污泥悬浮区,稳定运行时COD的容积负荷可达10～12 kg/m~3,COD去除率75%～80%左右,并具有启动速度快,颗粒污泥容易形成,耐冲击性负荷强等特点．更多还原

【Abstract】 In view of the defects of existing much“dead area”and decreased effective vol- ume caused by distribution water device of anaerobic reactor,a new type of external circular (EC) anaerobic reactor was researched and developed in this paper.By validated test study of brewage wastewater with the external circular anaerobic reactor,the results indicated that cyclone-flow distribution water device of external circular anaerobic reactor has a uniform dis- tribution water system.There are obvious particulate sludge area and suspended sludge area. The COD volume loading can reach 10～12 kg/m~3,the removal of COD is 75%～80%. The reactor have some advantages of quick start-up speed,tend to forming the particulate the sludge and enduring pulse load.更多还原
