外文摘要：Aerobic static litter composting， by using sawdust as main litter materials and adding with pig manure and pig slurry every day， under different ventilation rates of 0， 0。01 m3/min and 0。02m3/min was studied in pilot scale for obtaining the best ventilation rate。 The indexes such as temperature， C/N， germination index and microbial population were analyzed to examine effect of different ventilation on litter composting。 Re-sults show that: litter composting under ventilation rates of 0， 0。01 m3/min and 0。02m3/min can all realize high-temperature aerobic composting， and coliform bacteria accords with hygienic standard。 Ventilation can make high-temperature period prolonged， beneficial for innoxious disposal of litter composting， and ventilation rates of 0。02m3/min proved better。
