黄姜皂素工业固体废弃物的综合利用

Utilization of yam diosrenin industrial solid waste

黄姜皂素行业传统工艺产生的废渣的综合利用方法主要包括制备燃料、肥料、板材和活性炭以及栽培食用菌等,通过比较分析,提出利用废渣制备炭材料,并将其用于农业、废水处理等领域具有较好的经济技术价值,可以成为黄姜皂素行业废渣处置和利用的重要发展方向.此外,采用直接分离法生产皂素的新工艺可以减少环境和能源方面的压力,具有较高的清洁生产水平,是黄姜皂素行业的发展趋势.

We summarized the utilization methods of the residue generated by the traditional technology of extracting saponin from peltate yam rhizome,including manufacturing fuel,fertilizer,furniture materials,activated carbon,and cultivating edible fungi.Based on a comprehensive analysis of advantages and disadvantages of these methods,we proposed that using the residue to make carbon materials could be applied in agriculture and wastewater treatment,which has strong economic and technical feasibility and can be considered as an important approach of disposal and utilization of residue to yam diosgenin industry.In addition,the production of saponin using the direct separation technology can decrease the pressure on the environment and energy,showing a high level of cleaner production and being the development trend for saponin industry.
