Abstract
In order to solve problems of raw materialspresent in the compost reactor are compacted blocks, poorventilation performance, large ventilation resistance, anddifficulty in homogenizing the product, a helical ribbon andscrew impeller aerobic compost bioreactor was developed.Through numerical simulation of the flow field, it is proved thatthe helical ribbon and screw impeller has a good agitation andaxial flow property. The results of the composting test show thatthe time above 55°C for the top, middle, and bottom layers is 5.2,4.7, and 4.3 days. During the reaction, the oxygen concentrationwas over 8%, and the final seed germination index of each layerwas over 88%, which proved that the experimental reactor canachieve homogenization and can be effectively harmlesscompost.
