Embodiment 1

[0023] The pueraria starch processing waste residue wastewater treatment method comprises the following steps:

[0024] (1) Pre-mixing of waste water and waste residue: Centrally collect pueraria starch processing wastewater and waste residue, and under the stirring and shearing action of stirring shaft 3 and stirring blade 4, add waste water and waste residue to the specially prepared Homogenize for 30 minutes in the premixing area 1.1 of the processing equipment to obtain the mixture. At this time, the drawing plate between the premixing area 1.1 and the filtering area 1.2 is closed, that is, the premixing area 1.1 is separated from the filtering area 1.2;

[0025] (2) Enzymolysis: add 0.5 parts of cellulase to the mixture obtained in step (1), stir evenly, and enzymolyze at 30°C for 20 minutes to obtain an enzymolysis slurry;

[0026] (3) Solid-liquid separation: Open the pull-out plate between the pre-mixing area 1.1 and the filter area 1.2, and the draw-out plate between ...

Abstract

The invention discloses a method and device for treating waste residues and waste water coming from kudzuvine root starch processing. The method comprises the working procedures: pre-mixing of waste water and waste residues, enzymolysis, solid-liquid separation, multiple iron removal, grit removal, impurity removal, seasoning, decompression concentration, and drying. Through the method, waste water and waste residues generated in the processing process of the kudzuvine root powder are recycled, so that the treated waste water meets the standard and is discharged, substances such as starch, cellulose and some saccharides are recycled, and the economic value is improved.

Description

technical field [0001] The invention relates to a method and equipment for treating pueraria starch processing waste residue wastewater and belongs to the technical field of pueraria processing. Background technique [0002] Kudzu root contains 12% flavonoids, such as puerarin, daidzein, peanut and other nutrients, as well as protein, amino acid, sugar, and minerals such as iron, calcium, copper and selenium necessary for the human body. Desirable precious tonic. The current processing method for Pueraria lobata is to clean, peel, pulverize and beat fresh Pueraria lobata, filter, wash pulp, separate sedimentation and slurry, dehydrate, dry, etc., so as to obtain Pueraria lobata starch-based Pueraria lobata powder. The waste water and slag produced in this processing also contains some starch, cellulose and some carbohydrates, which are generally discarded directly in the prior art, resulting in waste and pollution. Contents of the invention [0003] In view of the defici...
