摘要:
In this study, a Fenton-like system was constructed by CaO2 and nano-Fe3O4 in the co-composting system of straw and sediment. Its effect on the passivation of heavy metals and the evolution of microbial community were investigated. The results showed that the establishment of CaO2-Fenton-like system increased the residual Cu and residual Zn by 27.62% and 16.80%, respectively. In addition, the CaO2-Fenton-like system facilitated the formation of humic acid (HA) up to 20.84 g·kg−1. Redundancy analysis (RDA) showed that the CaO2-Fenton-like syst...
