摘要
本文对由缺氧区-厌氧区-好氧区构成的新型组合式折流板反应器(CBR)处理模拟废水的过程进行了研究。通过实验研究了水力停留时间(HRT)、回流比、溶解氧浓度、碳氮比等因素对CBR去除COD、氨氮和总氮效果的影响。结果表明CBR具有良好的抗冲击负荷能力,在水力停留时间24h、回流比为200%、碳氮比为13的情况下,反应器具有最佳处理效果,COD、氨氮和总氮去除率分别达到90%,98%和80%。
This paper studied the operation characteristics of treating simulated municipal wastewater by a combined baffled reactor （CBR） composed of anoxic area/anaerobic area/aerobic area. The influence of hydraulic retention time （ HRT）, recycle ratio, DO, carbon/nitrogen ratio on COD, NH3-N and TN removal was investigated. The results indicated that CBR performance was relatively stable with respect to shock loading due to its special structure, CBR performance best in the condition of HRT = 24h, R =200%, C/N = 13. Removal rates of COD, NH3-N, TN reach 90%, 98%, and 80%, respectively.
