含氯代烃废水的生物毒性与处理方法探讨

卤代烃是在有机物分子中的碳原子上，用卤素基团取代出氢的卤化产物，这个变化使有机物的生物毒性增大，这是卤素有机态毒性的体现；另一方面，卤代烃在生物水解或降解过程中，又会重新释放出带正电荷的卤素，与水结合后成为次卤酸而具有无机态卤素的生物毒性。作者在提出这种卤代烃生物毒性学说的基础上，提出了一系列在含卤代烃废水预处理与生物处理中的解毒、降毒、抗毒和减荷及提高可生化性的措施，以提高含卤代烃废水的综合处理效率。

Discussion on the Bio-toxicity and Treatment of Wastewater with Chlorinated Hydrocarbon

When the Hydrogen in the organic molecule's carbon group is substituted by halogen,the compound is called halohydrocarbon.This substitution enhances the bio-toxicity of the organic compound(the toxicity of organic halogen).On the other side,halohydrocarbon can release electropositive halogen again in the process of bio-hydrolysis or bio-degradation,the released electropositive halogen can combine with water and show inorganic halogen bio-toxicity.Based on the halohydrocarbon's bio-toxicity theory,this paper...
