摘　　要：针对海水冲厕产生的高含盐生活污水,试验采用SBR工艺分别研究了不同海水盐度的污水中有机物的降解及氨氮的去除情况。结果表明,在高盐度污水的生物处理系统中,污泥的驯化是关键的一步。有机物和氨氮的去除率总体上随着盐度的增大而降低,但在海水冲厕范围内(海水比例在30%内,盐度为10500mg/L,Cl-为5700mg/L),海水盐度对有机物及氨氮的去除影响不大。This study was initiated to treat high salinity domestic sewage resulting from flushing toilet with seawater by SBR process.Experiments were conducted under different seawater salinity conditions to investigate the degradation of organics and ammonia removal efficiency.Results showed that the acclimation of the activated sludge was very important.With the increasing of seawater salinity,the removal efficiency of organics and ammonia decreased.But within flushing toilet with seawater(the seawater was within 30%;seawater salinity was 10 500 mg/L and Cl-concentration was 5 700 mg/L),the effect of seawater salinity on the removal efficiency of organics and ammonia was not serious.
