Abstract：A period of 56d of simulated pig manure and rice husk composting experiment was carried out to study the conversion and loss of carbon (C) and nitrogen (N) in the novel hyperthermophilic pre-treatment plus an in-vessel post-composting process (HPC) and the conventional in-vessel composting (CK) process, by using a self-designed hyperthermerphilic pretreatment reactor. The results showed that the maximum carbon degradation degree in CK (42.58%) was smaller than that of HPC (49.29%), but the carbon degradation rate constant in CK (0.1d-1) was greater than that of HPC (0.07d-1). The difference in C degradation in the two composting processes was not significant overall. The concentrations of NH4+-N and total N in the subsequent in-vessel composting of HPC were 143.9% and 11.2% higher than that in CK. The nitrate concentration in HPC, by contrast, was lowered by 58.8%. During composting, the content of humic acid (HA) and the ratio of HA to fulvic acid (FA) were on average 45.2%~56.8% and 59.1%~65.3% higher than that in CK duirng the later stage of composting. The carbon loss during the pretreatment process and subsequent in-vessel composting process in HPC and CK were 48% and 51%, respectively. The loss rates of N were 18% and 27% in HPC and CK, respectively. It was concluded that hyperthermophilic pretreatment could not only reduce the nitrogen loss significantly during composting process, but also promote the transformation of FA to HA, resulting in improved humification level of composting products.
