[0002] Laboratory fermentation waste liquid refers to the waste liquid generated after fermentation experiments in the laboratory. These waste liquids usually contain a variety of organic and inorganic substances, including carbohydrates, proteins, amino acids, fatty acids, vitamins and minerals, as well as inorganic salts such as sodium, potassium, calcium, magnesium, phosphorus, etc. These waste liquids are difficult to treat, mainly because of their complex composition and the presence of a variety of organic wastes and microorganisms.
