[0002] Potato is an annual herbaceous plant of the Solanaceae family. Its tubers are edible and it is the fourth most important food crop in the world, second only to wheat, rice and corn. Potato is also called ground egg, potato, sweet potato, etc. The tuber of Solanaceae plants is known as the world's five major crops together with wheat, rice, corn and sorghum. In the industrial processing and production of potatoes, a large amount of water is needed to rinse them, and the used sewage carries a large amount of potato peels and residues, which contain a large amount of protein, starch, fine fiber, polypeptide, polysaccharide, ribose, organic acid and inorganic salt. If it is discharged directly without water treatment, it will cause serious environmental pollution.
