摘　　要：研究了海水进入城市污水系统后，不同海水盐度下传统活性污泥处理系统的 Ｃ Ｏ Ｄ 去除率、耗氧率、基质氧利用率的变化。结果表明，进水中海水比例小于３６ ％ 时，盐度并没有降低系统对有机物的去除效率，应用该法处理含盐废水是可行的。海水比例超过４８ ％ 时则不然， Ｃ Ｏ Ｄ 去除率显著降低，出水 Ｃ Ｏ Ｄ 超过５０ ｍｇ／ Ｌ。The effect of salinity variation on the traditional activated sludge process is described in this paper.The COD removal,oxyen uptake rate and oxygen utilization rate of substrates were studied under different seawater concentration.The results showed that COD removal had not deteriorated when the percentage of seawater was less than 36%,but when the percentage was over 48%,the COD removal decreased significantly,and COD in effluent was over 50 mg/L.
