摘要
采用弹性立体填料的复合式厌氧反应器处理城市污水。研究结果表明 ,该装置处理城市污水效果显著 ,当进水COD在 87~32 0mg L范围内 (平均 2 2 7mg L)变化 ,水力停留时间大于 5 .2h ,反应系统的容积负荷小于 0 .86KgCOD m3.d时 ,常温下COD去除率大于60 % ,出水COD平均为 81mg L ,SS去除率大于 77.8% ,出水SS小于 30mg L ;反应系统在试验条件下温度与溶解性COD去除率成正相关。试验还得出了系统处理城市污水溶解性BOD5去除率随HRT变化的降解动力学模式。
A pilot unit of HABR (hybrid anaerobic baffled reactor) for sewage treatment is described in this paper. The pilot experimental results show the typical removals of COD and SS: over 60% and 77.8% respectively. A degradation kinetic model of soluble BOD against HRT for sewage is also built.
