| 摘 要： | 以猪粪为主要原料的沼气发酵系统中,24天的生物发酵试验结果表明:镉主要残存在不可溶的沼渣中;无论是沼渣、沼液,还是两者的自然混合体系中,其镉、铜、锌的含量均未表现出明显的动态变化趋势;沼液中的镉、铜、锌含量小于沼渣中镉、铜、锌含量,其存在比例随沼渣的含水量、沼液悬浮颗粒含量的变化而变化。

| Abstract: | With the fermentation of pig excrement in 24 days,in the fermented liquid,fermented solid and the mixture of both,a dynamical change of cadmium content,zinc content and copper content had not been observed.On the other hand,the cadmium content,zinc content and copper content of fermented liquid were greater than those of the fermented solid.Furthermore,cadmium content,zinc content and copper content of fermented solid changed with contents of water and suspended solids. |
