Food processing wastewater treatment
The food industry has a wide range of raw materials and a wide variety of products, and the quality of the discharged wastewater varies greatly.
The main pollutants in wastewater are:
1 Solid substances floating in waste water, such as leaves, peels, scales, minced meat, bird feathers, animal hair, etc.;
2 oil, protein, starch, colloids, etc. suspended in waste water;
3 sugar, acid, alkali, salt, etc. dissolved in waste water;
4 from the mud and sand of the raw materials and the droppings of the animals;
5 possible pathogens and the like. The main characteristics of food industry wastewater are high content of organic substances and suspended solids, easy to be spoiled, and generally non-toxic.
The main pollution hazard of the food industry wastewater is to cause the water body to cause the death of fish and Other aquatic animals, and to promote the decomposition of organic substances under the anaerobic conditions, generate odor, deteriorate the water body and pollute the environment. The animal's gastrointestinal tract is washed during the processing, so that the wastewater contains pathogenic bacteria. If it is not treated, it will be arbitrarily discharged, which will spread the disease and endanger the health of humans and animals.
