Oil containing wastewater water flotation machine for food factory wastewater treatment

The main pollutants in food factory wastewater include: (1) solid substances floating in the wastewater, such as vegetable leaves, fruit peels, minced meat, poultry feathers, etc. (2) substances suspended in the wastewater, such as oil, protein, starch, colloidal substances, etc. (3) acids, bases, salts, and sugars dissolved in the wastewater (4) mud, sand, and other organic matter carried by raw materials, etc. (5) pathogenic bacteria and toxins, etc

Due to the wide variety of food types and diverse sources of raw materials, wastewater from the food industry is characterized by high suspended solids and oil content, high levels of heavy metal ions, large COD and BOD values, unpredictable changes in water volume, high nitrogen and phosphorus compound content, and in some cases, high water temperature. The sewage treatment process is divided into primary treatment, secondary treatment, and tertiary treatment. For food industry wastewater, the primary treatment generally uses solid-liquid separation technology to remove suspended and floating solids from the wastewater; Secondary treatment is the main treatment process, generally using biological treatment technology to remove toxic substances such as organic matter in water, and generally using membrane treatment methods, strong oxidants, and other technologies to further evolve sewage.

The characteristics of food processing wastewater include the generation of sludge, waste oil, waste acid, waste alkali, and the harmless treatment of animal and plant waste generated during the processing of food wastewater. The food industry has a wide range of raw materials and a wide variety of products, and the processing requires a large amount of water, resulting in a lot of waste being discharged as sewage. The amount and quality of wastewater discharged vary greatly.

The main pollutants in food factory wastewater are:

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

(2) Substances suspended in wastewater include oil, protein, starch, colloidal substances, etc

(3) Acid, alkali, salt, sugar, etc. dissolved in wastewater

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

(5) Pathogenic bacteria and toxins, etc

The function of laminar air flotation sewage treatment machine

1. Horizontal air flotation has a high unit flotation capacity and high utilization rate of dissolved air, so it can be used to treat wastewater with very high suspended solids, with a value of up to 20000mg/L. Paper making wastewater with suspended solids content of thousands of mg/L can be easily reused using this equipment.

2. Can separate floating materials such as algae from 1UM-10UM.
