Project location: Taixing City, Jiangsu Province
Processing scale: 10000 tons/day (new construction)
Project Background: This project is a traditional Chinese medicine wastewater, mainly composed of polysaccharides, plant proteins, alkaloids, lignin, pigments, etc. The characteristics of this type of wastewater are high organic matter and high chromaticity.
Design inlet and outlet water quality:
