Abstract

The invention provides a method for retreating wastewater after pueraria starch processing. The method particularly includes: collecting wastewater after pueraria starch extraction; adopting a concentration unit to heat for concentration and water volatilization to obtain puerarin size of 30-40% in water content; lyophilizing, and smashing to obtain puerarin. The concentration unit is adopted to heat for concentration and water volatilization, so that the wastewater after pueraria starch processing can be concentrated into the puerarin size of 30-40% in water content in one step, and convenience is brought to subsequently drying and smashing the puerarin size to obtain puerarin.

Description

technical field [0001] The invention relates to a method for reprocessing waste water after pueraria starch processing. Background technique [0002] At present, kudzu root starch production enterprises mostly use kudzu root as raw material, and obtain kudzu root starch through the following processing steps: 1. Clean the collected kudzu root; 2. Crush kudzu root to obtain kudzu root slurry; , to obtain starch-containing separation slurry; 4. The separation slurry is dehydrated and dried to obtain Pueraria starch, and the dehydrated waste water is directly discharged. [0003] The problem is that the production process of kudzu starch only pays attention to the single product of starch, and the discharged wastewater contains puerarin, which causes a great waste of resources. Contents of the invention [0004] In order to reuse the waste water after the pueraria starch is extracted, the invention proposes a method for reprocessing the waste water after the pueraria starch ...
