鱼粉废水中固体物质含量约占23％，其主要成分是鱼粉、鱼油、碎鱼骨等，鱼粉废水蒸发后为糊状物（固体物质含量约占65％）．考察不同的革取剂、用料比（糊状原料／萃取剂）、温度、离心分离时间、萃取次数等工艺条件．回收鱼粉的最佳萃取剂是乙醇、用料比1／2g·mL－1、室温、离心分离10min、萃取三次为最佳试验条件．20g糊状物可制备6g鱼粉，且符合SC／T-3501－1996鱼粉标准． The content of solid substances in fishmeal wastewater accounts for about 23%. The main components are fishmeal, fish oil and broken fishbone. The fishmeal wastewater is evaporated into paste (solid content about 65%). Investigate different leather, material ratio (pasty material / extractant), temperature, centrifugation time, extraction times and other process conditions. The best extractant for recovering fishmeal was ethanol. The optimal conditions were as follows: 1 / 2g · mL-1, room temperature, centrifugation 10min, extraction three times. 20g paste can be prepared 6g fish meal, and in line with SC / T-3501-1996 fish meal standards.
