摘　　要：运用"烟囱效应"研制成一种新型引风式好氧堆肥装置,研究其对通风供氧的影响效果。通过对园林垃圾与餐厨垃圾混合堆肥试验表明:本装置能有效地改善静态堆肥过程的通风供氧效果,保证好氧堆肥的顺利进行,一次发酵周期内堆体平均氧浓度由9.7%提高至16.3%,最低氧浓度提高至12.6%,一次发酵周期由12 d缩短至10 d。Abstract：residue eo-eomposting test showed that this device had signification effect on improving ventilation and oxygen supply for static composting, and ensured the smooth progress of aerobic composting. The average oxygen concentration was raised from 9. 7% to 16. 3% while limiting oxygen concentration increased to 12. 6% in the period of one-stage composting,and periodic time reduced to 10 days from 12 days.
