Product Name: Smoked Food Wastewater Treatment Equipment

Detailed information:

The food industry has a wide range of raw materials and a wide variety of products, resulting in significant differences in the amount and quality of wastewater discharged. The main pollutants in wastewater include solid substances floating in the wastewater, such as vegetable leaves, fruit peels, minced meat, poultry feathers, etc. The suspended substances in the wastewater include oil, protein, starch, colloidal substances, etc. The dissolved acids, alkalis, salts, sugars, etc. in the wastewater, as well as sediment and other organic substances carried in the raw materials, which can cause bacteria.

The main sources of wastewater in the food industry are from three production stages.

1. Raw material cleaning section: A large amount of sand, debris, leaves, skin, scales, meat, feathers, hair, etc. enter the wastewater, causing a large amount of suspended solids in the wastewater.

2. Production section: Many components in the raw materials cannot be fully utilized during the processing, and the unused parts enter the wastewater, resulting in a large amount of organic matter in the wastewater.

3. Forming section: In order to increase the color, aroma, and taste of food and extend its shelf life, various food additives are used, and some of them are lost into the sewage, making the chemical composition of the sewage complex.

Dissolved air flotation technology has been widely used in water supply, drainage, and wastewater treatment in recent years. It can effectively remove light flocs that are difficult to precipitate in wastewater. Large processing capacity, high efficiency, small footprint, and wide range of applications. Widely used in wastewater treatment for petroleum, chemical, printing and dyeing, papermaking, oil refining, leather, steel, mechanical processing, starch, food and other industries. After the chemical addition reaction, the sewage enters the mixing zone of air flotation and comes into contact with the released dissolved air water, causing the flocs to adhere to fine bubbles before entering the air flotation zone. Under the action of buoyancy, flocs float towards the water surface to form floating scum. The clear water in the lower layer flows through the collector to the clear water tank, and a part of it is refluxed for use as dissolved water. The remaining clear water flows out through the overflow port. After the floating slag on the surface of the air flotation tank accumulates to a certain thickness, it is scraped into the sludge tank of the air flotation machine by a scraper and discharged.
