Research on a two-room composting bioreactor
两室堆肥生物反应装置研究

A two-room composting bioreactor was designed based on mass balance,heat balance and characteristics of composting biochemistry,and its rationality was tested through composting experiments.The main components of the bioreactor were:a two-room fermentation case,a thermal insulation layer,an air supplying system,an air heating system,and a secondary pollution prevention system.The bioreactor had the following characteristics:(1)each of the two rooms of the fermentation case could complete the whole composting process independently,and could also be used as the primary and second fermentation case respectively when they were combined.(2)Discharges of odor gas and wastewater were obviously decreased by the secondary pollution prevention system.(3)The air heating system could heat composting material quickly and uniformly,to satisfy requirements of different composting technics.The bioreactor could be used in experimental studies and small-scale waste composting.
