Buried Integrated Food Processing Sewage Treatment Equipment

Characteristics of food sewage

The food industry has a wide range of raw materials and a wide variety of products.The main pollutants in the wastewater include (1) solid substances floating in the wastewater, such as vegetable leaves, fruit skins, ground meat, and bird feathers.(2) the substances suspended in the wastewater include oil, protein, starch, colloidal substances, etc.(3) acid, alkali, salt, sugar, etc. Dissolved in the wastewater :(4) mud sand and other organic matter carried by the raw material;(5) pathogens, etc.Food industry wastewater is characterized by high content of organic matter and suspended matter, easy to decay, generally no great toxicity.Its harm is to make the water eutrophication, which causes the death of aquatic animals and fish, causes the organic matter deposited in the bottom to produce a bad smell, deteriorates the water quality, and pollutes the environment.Food sewage treatment equipment manufacturers direct

Food sewage treatment methods

In addition to proper pretreatment according to the characteristics of water quality, biological treatment should be generally adopted in the treatment of food industrial wastewater.In case of high requirements on effluent quality or high organic matter content in wastewater, two-stage aeration tank or two-stage biological filter tank or multi-stage biological rotary table can be used.Or the combination of two biological treatment devices, or the use of anaerobic - aerobic biological treatment system in tandem.

Food sewage treatment equipment -- buried sewage treatment equipment features:

1, buried below the surface, the surface above the equipment can be used for afforestation or other land, do not need to build houses, heating, insulation.

2. The secondary biological contact oxidation treatment process adopts 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 the activated sludge tank, it is small in size, has strong adaptability to water quality, good impact resistance performance, stable effluent water quality, and no sludge swelling.A new type of elastic solid filler is used in the tank, which has a large specific surface area, and the microorganism is prone to film hanging and film stripping. Under the same organic load condition, the removal rate of organic matters is high, and the solubility of oxygen in air in water can be improved.

3. The biochemical tank adopts the biological contact oxidation method, the volume load of the filler is relatively low, the microorganisms are in their own oxidation level, and the mud production is small, only three months (90 days) more than once mud (with a manure cart suction or dehydration into mud cake for transport).

4. The deodorization method of the buried domestic sewage treatment equipment adopts the conventional upper air exhaust and the soil deodorization measures.

The entire equipment processing system is equipped with automatic electrical control system and equipment fault alarm system, safe and reliable operation, usually do not need a person to manage, just timely maintenance and maintenance of equipment.
