  • 摘要: 采用商品化的餐厨垃圾降解菌剂和自主筛选的抗酸化复合菌剂制备餐厨垃圾液态有机肥,对比分析不同菌剂对餐厨垃圾制备液态有机肥过程中固液两相物质转化的影响,阐明餐厨垃圾制备液态有机肥过程中有机质、糖类、粗蛋白等物质的转化规律。结果表明:2组菌剂均可降低餐厨垃圾中的有机质和粗蛋白浓度,提高液相游离氨基酸浓度;其中接种抗酸化复合菌剂效果更佳,处理后餐厨垃圾固相有机质、粗蛋白浓度下降比例分别为1.17%、15.41%,分别是餐厨垃圾降解菌剂组浓度下降比例的3.66和1.66倍;反应96 h时,液相游离氨基酸浓度达到770.6 mg/L,是餐厨垃圾降解菌剂组浓度的1.24倍;前48 h时,抗酸化菌剂组液相中总糖和还原糖利用率均达到91%以上,而餐厨垃圾降解菌剂组均仅为28.52%。抗酸化复合菌剂可有效促进餐厨垃圾中大分子有机物转化为可溶性小分子有机物以及游离氨基酸,有望为餐厨垃圾高值化液态有机肥的制备提供技术支撑。
