摘要/Abstract

摘要： 研究了不同堆肥阶段氧气浓度和耗氧速率的变化特征.结果表明,不同堆肥阶段通风补充氧气所需的时间很短,各阶段通风后氧气浓度都恢复到17%以上.堆肥升温阶段、高温阶段初期耗氧速率高,达900 μl·L^-1·s^-1以上;随着堆肥的进行,耗氧速率逐渐降低.经过5～7 d的持续高温期后,耗氧速率下降到100 μl·L^-1·s^-1以下,堆肥基本腐熟.根据耗氧堆肥的氧气动态变化特征,提出了相应的通风策略.

Abstract: Analysis with oxygen monitoring system on the variation of oxygen concentration at different stages of pig manure composting showed that in a short time after ventilation at different composting stages,the oxygen concentration increased by 17% or more,and the oxygen consumption rate at temperature increasing stage and at the beginning of high temperature stage could reach up to more than 900 μl·L^-1·s^-1,while decreased at the stages of high temperature and of dehydration as the composting process going on.The oxygen consumption rate decreased to lower than 100 μl·L^-1·s^-1 after 5～7 days at the stage of high temperature.A ventilation strategy was proposed based on the analyses.

Key words: Pig manure, Compost, Oxygen consumption rate, Ventilation
