| 摘 要： | 为了解决餐厨垃圾回收处理难等问题，探索餐厨垃圾资源化利用，以学校食堂餐厨垃圾作为研究对象，经过固液粗分后，重点研究了废液发酵培养粘红酵母获得菌体的可行性，最后以大豆为实验材料，分别研究了固体垃圾和发酵菌体作为生物肥料的肥效。实验结果表明，粘红酵母可以利用餐饮废水，最佳发酵时间24 h时获得菌体干重12 g/L；粘红酵母最适宜生长pH为 5.5；固体垃圾和发酵菌体对幼苗期大豆豆苗的生长有一定的促进作用，按照每公顷的最佳施用量为450 kg。 |

| Abstract: | Exploring food waste recycle as a starting point and the cafeteria food waste was the research object in this paper. After solid-liquid separation, the feasibility of cultivation fermentation of Rhodotorula glutini in the waste liquid and obtaintion of the bacteria had been studied. At last, the efficiency of biological fertilizer including soild waste and fermentation bacteria had been researched in soybean. The results showed that, Rhodotorula glutini could make use of food waste. The dry weight of bacteria was 12 g/L when it had been fermented 24 h in optimal level. The pH value of 5.5 was the best conditions. Moreover, solid waste and bacteria could promoted the growth of soybean shoots when use 450 kg per 1 m2. |
