Effects of combined membrane-covered systems on aerobic composting of strawberry vine and chicken manure

Abstract

A combination of semipermeable membrane-covered composting systems and greenhouses was used to investigate the effects of different insulation systems on the aerobic fermentation of mixed raw materials and changes in the characteristics of fermentation feedstock. The combination of semipermeable membrane-covered and greenhouse systems increased the peak temperature by 6.53 °C, the average fermentation temperature by 28.2%, and extended the duration of the effective high-temperature stage of fermentation (temperature ≥ 50 °C) by 14 days. The decomposition percentage of solid organic matter in the enhanced group was 11.8% higher than that in the normal group, and the fermentation cycle was shortened by 5 days. The duplication provided by using both the semipermeable membrane-covered and greenhouse systems was conducive to the harmless treatment of raw materials, promoted the maturity and efficiency of composting, and reduced the content of biologically toxic substances. This study provides a theoretical basis for improving the efficiency of aerobic fermentation and the safe treatment of solid waste.
