摘要
以 BOD5/CODCr值表征有机物的生物降解性 ,对影响取代苯胺生物降解性的因素进行了研究。结果表明 ,随着浓度的升高 ,取代苯胺的生物降解性降低 ,BOD5/CODcr的对数值与浓度对数值成线性关系。在较宽的 p H值范围内 ,部分取代苯胺的生物降解性变化不大。盐浓度的增大对取代苯胺的生物降解产生明显的抑制作用。
The factors affecting substituted anilines' biodegradability which was expressed by BOD 5/COD Cr were studied. The results showed that the biodegradability decreased when concentration of organic chemicals increased; logarithm of BOD 5/COD Cr and that of concentration have linear relation. Biodegradability of some substituted anilines has little changes in a wide range of pH value. Increase of salt concentration render biodegradability dramatically.
