Abstract: The invention refers to ammonia sulfate utilization patterns in the process of lysine, the characters of which include the evaporation and concentration of wastewater (mother liquid) after refining and separating lysine; in which the ammonia sulfate separated by crystallization is recrystallized, purified and separated, afterwards is sent back to fermentation production used as raw material; the waste mother liquid after fractional crystallization of ammonia sulfate is used for raw material in producing composite fertilizer. The technical project in recycle of ammonia sulfate introduced in the invention realizes the reasonable recycle and the cycle comprehensive utilization of useful ammonia sulfate in wastewater (mother liquid), that not only reduces the solid in wastewater and also realizes the cycle comprehensive utilization of raw material. That has suitable control condition and obvious economic value.
