摘　　要：陶瓷平板膜生物工艺(C-MBR)是基于陶瓷平板膜所开发的生物处理工艺,该工艺已广泛应用至生活污水、工业废水处理及回用领域。循环比是C-MBR工艺的重要设计参数之一,本文针对不同循环比对C-MBR工艺的影响进行研究。实验结果表明,在循环比150%、200%、250%、300%、350%、400%的情况下,C-MBR均有较强的有机物降解能力,出水COD均在60 mg/L以下,达到国家一级A标准;脱氮除磷方面,循环比为200%时NH4+-N去除效果最好,去除率可达83.49%;循环比为350%时,脱氮除磷效果最佳,TN、TP去除率分别可达24.99%、25.86%。Ceramic-membrane bioreactor （C-MBR） is a biological processthat is developed from ceramic fiat-sheet membrane. The C-MBR process has been widely applied in domestic sewage treatment and industrial waste water treatment. Recycle ratio is one of the important design parameters in C-MBR process. In this paper, different recycle ratios were studied on their impact on C-MBR process. Results showed that, under the ratios of 150%, 200%, 250%, 300%, 350% and of 400%, C-MBR process showed a relatively high level of organic matter degradation capabilities with effluent COD of 60 mg/L. This could meet the national primary discharge standard. For the nitrogen and phosphorus removal, the ratio at 200% showed good efficient result of ammonia nitrogen removal at 83.49%, and the ratio at 350% showed the optimal effect of nitrogen and phosphorus removal at 24.99% and 25.86%, respectively,
