| 摘 要： | 海水冲厕是一项具有重大节水意义的工程。针对所产生的含盐生活污水的处理 ,试验研究NaCl盐度对活性污泥处理系统的综合影响。分别研究不同盐度驯化下活性污泥的生长、有机物降解和去除情况、SBR反应系统内溶解氧随时间的变化以及污泥沉降性等。试验结果表明 ,NaCl盐度影响了微生物的生长 ,降低有机物降解速率和去除率 ,但是却增强了细胞的溶胞作用和微生物的呼吸作用

| Abstract: | This study was initiated to treat saline sewage resulting from use of seawater for toilets by SBR process and to determine the NaCl salinity effects on the activated sludge treatment system.Experiments were conducted under various salt-loading conditions to investigate such as treatment culture,organic matter removal,sludge settling characteristics and the rule of DO varying with time.The study found that high salinity inhibited the microbial growth and decrease organic matter degrading velocity and removal efficiency while microbial respiration and cell lysis were strengthened. |
