Characteristics and process of sewage treatment equipment in food factory

The sewage produced by food has always troubled our life. The sewage from food enterprises contains various inorganic and organic pollutants, as well as many bacteria, including Escherichia coli, possible pathogenic bacteria and miscellaneous bacteria, so the water quality is muddy and dirty. To treat food sewage, we need food sewage treatment equipment.

Features of sewage treatment equipment in food factory:

1. The complete set of equipment can be buried under the frozen layer or placed on the ground. The ground above the equipment can be used as greening or other land, without building houses, heating and thermal insulation.

2. The secondary biological contact oxidation process adopts the push-flow biological contact oxidation, and its treatment effect is better than that of the fully mixed or two-stage series fully mixed biological contact oxidation tank. Compared with activated sludge tank, it has smaller volume, strong adaptability to water quality, good impact load resistance, stable effluent quality and no sludge bulking. The new elastic solid filler is used in the tank, which has a large specific surface area and is easy for microorganisms to hang and remove the membrane. Under the same organic load conditions, the removal rate of organic matters is high, and the solubility of oxygen in the air in water can be improved.

3. The biological contact oxidation method is adopted for the biochemical tank. The volume load of its filler is relatively low, the microorganism is in its own oxidation stage, and the sludge production is small. It only takes more than three months (90 days) to discharge the sludge (pumped or dehydrated into sludge cake for outward transportation).

4. In addition to conventional high-altitude exhaust, the deodorization method of food sewage treatment equipment is also equipped with soil deodorization measures.

5. The entire equipment processing system is equipped with a fully automatic electrical control system, which is safe and reliable in operation. Usually, it does not need special personnel to manage, but only needs to maintain and maintain the equipment in a timely manner.
