| Abstract: | Composting static vessel was set to investigate physico-chemiea properties in night-soil/waste composting with different amendments. The results showed that maize straw was the best amendment that could adjust porosity and structural strength of the compost materials in comparison with sawdust, dry leaves and rice hull. Moisture contents decreased sharply in thermophi｜ic stage, gradually in maturity stage. Higher porosity and high temperature showed positive effects to moisture volatilization. Acidification at start-up stage could be reduced by adding lime at dosage of 2%, leading to rapid rising of temperature and shorting composting period. Rational mixing rates of dewatering night-soil, domestic waste, maize straw and lime stayed at 30%/60%/8%/2%. |
