摘要：

In order to make the animal manure resource and harmless, the effect of passivation agent on the passivation of heavy metal in the composting of animal manure was discussed. In this paper, the effects of cotton stalk wood vinegar on the speciation of Cu and Zn in cow manure composting were studied by using cow manure for high temperature aerobic composting. The results showed that the passivation effect of the added cotton stalk wood vinegar on heavy metal Cu and Zn was significantly higher than that of the control group, the passivation ability of Cu was T4 > T3 > T5 > T2 > T1 > CK, and the passivation ability of Zn was T4 > T3 > T5 > T2 > T1 > CK. The effect of heavy metal Cu and Zn Passivation was the best when the ratio of cotton stalk wood vinegar was 0.65%, and the value was 21.72% and 33.11% respectively.
