生物处理含氯代脂肪烃废水的研究进展

Progress in Research on the Biological Treatment of Wastewater Containing Chlorinated Aliphatics.

从降解菌种及涉及的酶体系、降解过程机理、降解动力学和所用反应器等４方面对氯代脂肪烃的生物降解的研究作了综述。文献表明：通过驯化，某些菌种能在特定条件下降解氯代脂肪族物质。还介绍了降解菌种的特征，降解的可能途径和动力学模型，并比较了各种氯代脂肪族组分的可生物降解性。同时对降解所用的反应器进行了评价。

In order to address the issue of general concern posed by chlorinated aliphatics which are toxic or even carcinogenic and have caused underground water pollution in some locations, a review based on references was made on the biodegradation of chlorinated aliphatics, including the strains and enzyme systems involved in such a degradation , the mechanisms of degradation processes,the kinetics of degradation, and the reactors used for such a purpose.The review also relates to the conditions under which some of acclimated strains can degrade chlorinated aliphatics,the features of a strain having such a function,the possible paths of such a degradation and their kinetic models, the biodegradabilities of various components of chlorinated aliphatics,and an evaluation on the reactors which have been used for such a biodegradation.
