Efficient degradation process for vomitoxin in corn steep liquor

The invention discloses an efficient degradation process for vomitoxin in corn steep liquor, and belongs to the technical field of corn deep processing. Comprising the following steps: (1) removing solid matters from corn steep liquor through a vertical plate-and-frame filter, adding tartaric acid and calcium hydroxide after removing impurities, and filtering through the plate-and-frame filter to remove precipitates so as to obtain corn steep liquor filtrate; (2) performing calcination reaction on sulfur to obtain sulfur dioxide; (3) performing detoxification reaction on the corn steep liquor filtrate, a catalyst and sulfur dioxide to obtain detoxified feed liquid; (4) introducing carbon dioxide into the detoxified feed liquid for reaction to obtain corn steep liquor without vomitoxin; and (5) adding hydrogen peroxide into the vomitoxin-removed corn steep liquor to react, thereby obtaining the detoxified corn steep liquor. The corn steep liquor vomitoxin can be obviously degraded, the additional value of the
