摘要/Abstract

摘要： 研究了中试规模的一体化MBR系统处理校园生活污水的性能。该系统运行了110天,在第51-56
天停止进水,采用人工补给尿素和淀粉的方法保证污泥的存活;第57天重新进水。在连续进水的两个阶段,对该系
统不同处理段的COD、BOD5、ρ(NH4+-N)和TP进行了定期测定,平均去除率分别达到95.10%、90.96%、93.02%
和93.37%,厌氧池在去除上述指标时起主要作用。反映好氧池中污泥沉降性能的混合液悬浮固体(MLSS)的质量
浓度和污泥沉降比(SV)逐渐增大后稳定在8600mg/L和85%。污泥体积指数(SVI)一直低于112.1mg/L。反映
污泥活性的挥发性悬浮固体(MLVSS)的质量浓度与MLSS的质量浓度的比值在整个实验过程中呈较弱的下降趋
势,尤其在后期更为明显。结果说明该系统中生物污泥具有良好的生物活性和沉降性能,抗冲击负荷能力高,适合
实际生活污水的回收利用。

Abstract: A 110 days'experiment was carried out to study a pilot-scale integrative A/O(anaerobic/ aerobic) MBR treating domestic wastewater from an university. Influent wastewater was stopped from day 51 to day 56 and the activated sludge was feeded by faecula and urea, and inlet was restarted on day 57. Chemical Oxygen Demand(COD)，Biochemical Oxygen Demand(BOD5)，Ammonia Nitrogen(NH+4N) and Total Phosphorus (TP) concentration was investigated in different part of the system. The average removal efficiency of COD,BOD5, ρ(NH+4-N),TP was 95.10%，90.96%，93.02% and 93.37%, respectively, mainly digested in anoxic tank. MLSS and SV in the aeroic tank increased gradually and stayed steadily on 8 600 mg/L and 85%, respectively. SVI was lower than 112.1 mg/L during the whole experiment. The value of MLVSS/MLSS, which reflects the sludge activity, descended slightly in 110 days'study, especially on the anaphase. The results shows a promising future for the application of this system for municipal wastewater reclamation.
