受控生态环境中植物不可食部分固废预处理技术研究

Study on Pretreatment Technology of Inedible Biomass in Controlled Ecological Life Support System Integrated Experiment

目的开发适用于地基密闭受控生态生命保障系统内植物不可食部分固废预处理技术及设备,为地外星球基地建设提供技术储备。方法采用闭环空气干燥技术和两级粉碎技术对植物不可食部分固废进行干燥和粉碎处理。结果经干燥和粉碎预处理后的植物不可食部分,含水率降低至30%以下,减容率达到56%。实现了干燥、稳定和减容处理,同时植物不可食部分中的水分得到回收。结论闭环空气干燥技术和两级粉碎技术满足地基密闭受控生态生命保障系统的要求,经处理后的植物不可食部分固废可长期稳定保存或进一步进行资源化处理。

Objective To develop the technology and equipment for solid waste pretreatment of inedible parts of plants in controlled ecological life support systems( CELSS),and make technical reserves for the construction of extraterrestrial planet base. Methods Closed-loop air drying technology and two-stage comminuting technology were used to treat the inedible parts of plants. Results After the pretreatment,the moisture content of the inedible parts of the plant was reduced to less than 30%,and the volume of the waste was reduced to 56%.The objectives of drying,stabilization,and volume reduction were achieved and the water in the inedible parts of the plant was recovered. Conclusion The closed-loop air drying technology and the two-stage crushing technology could meet the requirements of controlled ecological life support system. After treatment,the inedible parts of plants can be stably stored for a long time or further processing.
