海水浓度对生物接触氧化法处理废水的影响

The impact of sea-water concentration on biologicaloxidation effluent treatment

研究了海水浓度对生物接触氧化法处理废水的影响。结果表明 ,在淡水中添加海水超过35%时 ,生物接触氧化法去除废水的化学耗氧量 (COD)的效果随着海水浓度的增加而降低 ,添加海水10%～25%时 ,COD的去除效果好 ,25%时COD最高总去除率可达87.8 % ,处理效果几乎与纯淡水的对照组 (COD总去除率88.6 % )等同。

This paper investigates the effect of sea-water concentration on the biological oxidation method of waste water treatment.Results showthat if sea-water content exceeds35%of total,seawater concentration is inversely proporˉtional to chemical oxygen depletion(COD).When the proportion of sea-water is between10%-25%of the total COD rate is good.At25%the highest removal rate is achieved at87.8%almost equal to that of the control(pure fresh water)at88.6%.
