混合发酵法降解多氯联苯的研究

该法可有效地降解多氯联苯,实验表明多氯联苯在木屑—活性污泥混合物或马粪中,发酵后均有一定程度的降解,特别是在降解过程中加入有利于微生物生长的营养成份,降解率明显提高。

TREATMENT OF PCBs BY COMPOSTING FERMENTATION PROCESS

PCBs are degraded effectively by composting fermentation process. The results of laboratory experiments show that PCBs are degraded to a certain extent in the fermented mixture of the activated sludge and wood chips or in the fermented horse dung. Especially, when some nutriment which contributes to the growth of micro-organisms is added in the process of degradation, the degradation rate of PCBs is markedly increased.
