Food Factory Wastewater

The main pollutants in wastewater are:

(1) Solid matter floating in wastewater, such as vegetable leaves, fruit peels, minced meat, poultry feathers, etc.;

(2) Suspended matter in wastewater includes oil, protein, starch, colloid, etc.;

(3) Acids, alkalis, salts, sugars, etc. dissolved in wastewater;

(4) Mud and sand and other organic matter carried by raw materials;

(5) Pathogenic bacteria and viruses, etc. The characteristics of food industry wastewater are high content of organic matter and suspended matter, easy to corrupt, and generally non-toxic. Its main harm is to cause eutrophication of water bodies, resulting in the death of aquatic animals and fish, causing organic matter deposited on the bottom of the water to produce odor, deteriorating water quality, and polluting the environment.
