| 英文摘要 | Harmless treatment of livestock manure has been a pressing issue due to its contamination of heavy metals and volatilization of nitrogen(N)-containing components during processing. In this paper, the chemical species transformation, leaching characteristics of Cr, Mn, Zn, Cu and conversion of amine N and inorganic N during composting and pyrolysis of swine manure (400 degrees C, 500 degrees C, 600 degrees C and 700 degrees C) were comparatively investigated, and their integrated environmental risk ( eta) was assessed. According to the ultimate and proximate analysis, pyrolyzed char exhibited better aromaticity and richer functional groups compared with that of compost; Cr, Mn, Zn, Cu were transformed into more stable residual states (F3+F4), and better inhibition of leaching in simulated landfill experiments was shown than compost. However, deamination and cyclocondensation reactions under higher pyrolysis temperatures resulted in N escaping in the form of NH 3 and HCN. Considering various pollution coefficients, the integrated ecological risk was reduced by 59.24 % after 600 degrees C pyrolysis, which is the optimal condition for the minimization of the risk of heavy metal toxicity and N volatilization among all the compost and pyrolysis process. |
