Food And Pharmaceutical Industry

Industry Introduction

With the development of the industry, the treatment of pharmaceutical wastewater has received more and more attention. As long as the wastewater generated by the industry contains a large amount of toxic organic matter, such as side chain lipids, petroleum ether, acetone, methanol, ethanol, dichloromethane, toluene, and various acid and alkali substances, it also carries cephalosporin antibiotic residues. This type of wastewater has complex components, high organic content, and large molecular weight. The toxic substances and antibiotics in the water have a strong inhibitory effect on the strains of biochemical treatment. It is one of the most difficult wastewaters to treat.

The food industry has a wide range of raw materials and a wide variety of products. The amount and quality of the discharged wastewater vary greatly. 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 substances in wastewater include oil, protein, starch, colloids, etc.

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

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

(5) Deadly pathogens, etc.

The characteristics of food industry wastewater are a 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.
