太阳能-生物反应器处理厨余垃圾的研究

The Research of Solar Energy-bioreactor for Kitchen Waste Disposal

通过对堆肥技术进行一定的改进,设计了厨余垃圾太阳能-生物反应器,并对其处理厨余垃圾进行了研究。结果表明,该反应器对厨余垃圾有很好的处理效果。含水率由85.3%降到61.0%;pH值由6.45升到8.48;生物可降解度由15.7%降到3.9%;C/N由24.1∶1降到16.4∶1;有机质由75.3%降到38.1%;堆肥周期缩短到20d左右,大大低于传统好氧堆肥工艺的堆肥周期。

Through improving composting technology,solar energy-bioreactor for kitchen waste was designed,and the disposal on kitchen waste was researched.The results showed that the reactor has great treatment effect on kitchen waste.Moisture content dropped from 85.3% to 61.0%;pH value raised from 6.45 to 8.48;biodegradable degree dropped from 15.7% to 3.9%;C：N dropped from 24.1∶1 to 16.4∶1 and organic matter dropped from 75.3% to 38.1%.The composting period was shortened to about 20 days,which significantly lower than the composting period of traditional aerobic composting.
