The food industry includes many industries such as meat processing, seafood processing, dairy processing, canned food production, brewing, sugar production, etc. Therefore, the food industry has a wide range of raw materials, a variety of product types, and significant differences in the amount and quality of wastewater discharged. However, overall, food wastewater has strong oxygen consumption and a large amount of suspended solids are discharged with the wastewater. Due to the fact that most of the raw materials used in the food industry are organic substances that can be digested by the human body, the biodegradability of food industry wastewater is generally good.
