| 中文摘要 |
| 以农业蔬菜和花卉废物为原料,进行了不同堆肥控制温度水平的共堆肥.试验在2m3的静态好氧床中试装置中,采用静态好氧工艺进行,研究分析了55℃,60℃,65℃3个温度控制水平下的废物减量化、底物降解、水分去除等的随时间的变化特征:总废物减量率分别为45.8%,63%和58.1%;有机质的降解率分别为23.4%、41.4%和23.8%;水分去除率分别为59.9%、79.1%和78%.60℃控温工艺的废物减量化效果最好,65℃次之,55℃最差;60℃控温工艺的底物降解能力最强,65℃和55℃工艺的底物降解效果相差不大;60℃和65℃控温工艺的水分去除能力最强,55℃条件下的水分去除能力较弱. |
| 英文摘要 |
| The effect of temperature control on vegetable waste and flower straw co-composting was investigated in pilot scale.The mixture of shredded vegetable waste and flower straw was composting in 2 m~3 static aerobic bed on the controls of three different temperature level(55℃,60℃,65℃).Of these trials,temperature,organic matter,moisture content were measured in order to research effect of temperature control on wastes reduction,biodegradation and moisture removal.As the control levels of temperature was 55℃,60℃,65℃ during composting,the ratios of wastes reduction were 45.8%,63% and 58.1%,respectively.And the ratios of wastes biodegradation were 23.4%,41.4% and 23.8%,respectively. And the ratios of water removal were 59.9%,79.1% and 78%,respectively.It was the most effective to control temperature of composting on about 60℃ among the three control levels of temperature trials,either base of biodegradation or moisture removal.The control temperature of 65℃ also have a powerful ability of moisture removal,but its biodegradation is not so efficient as that of 60℃.The control temperature of 55℃ have the worst ability to reducing wastes,degrading organic matter and removing water during the co-composting of vegetable and flower wastes. |
