摘要：

This The study concerned the evolution of maturity indices during the co-composting of poultry manure(P), municipal solid waste (M), corn straw(C) and lime(L) with aerobic static vessel. These indexes were pH, temperature, NH4+-N, NO3--N, water soluble total nitrogen (WSTN) and water soluble organic carbon(WSOC). The study was made three different mixtures MPC, PMCL1 and PMCL2 with M: P: C:L rations of 56:32:12:0, 61:26:9:4, 69:20:9:2, respectively(wet weight/ wet weight). The content of total nitrogen and NH3-N reduce gradually with the composting time. The content of NO3--N increases after high temperature period. The compost becomes maturity when the content of TN decreased 14.5%, NO3--N increased 67 times and WSOC below 31mg/g. Reference indices are temperature and pH.
