Food - Meat Processing Wastewater Treatment Equipment

The wastewater from the food industry contains a variety of substances, including suspended oils and fats, suspended solids, dissolved substances, organic matter, and bacteria. Common food wastewater includes substances such as meat processing, vegetable leaves, fruit peels, beverages, and soy products. If the wastewater generated during the processing of food is discharged without treatment or treatment that does not meet the standards, it will cause river pollution and fish death, resulting in foul odor of organic matter deposited on the bottom of the water, blackening of water quality, and environmental pollution.

Characteristics of food wastewater quality:

1. The nitrogen and phosphorus content in wastewater is high, and during the processing of meat and beans, nitrogen is produced from proteinCODThe processing of meat can easily increase the levels of nitrogen and phosphorus in wastewater;

2. There are many high concentration wastewater. Based on the experience of testing and treating wastewater from different food processing industries, general food wastewaterCODThe concentration can reach thousands to tens of thousandsmg/L；

3. High oil content, the meat processing industry and oil processing industry will produce a large amount of oil during the production process;

4. Wastewater contains various microorganisms and bacteria, and the water quality is prone to blackening and emitting a foul odor.

Common wastewater treatment methods: physical method, biological method, chemical method

Taking Hunan Qiaojiayin Food Factory as an example:

The main source of the company's wastewater is meat processing wastewater, which contains pollutants such as COD, ammonia nitrogen, phosphorus, etc.

Based on the characteristics of the company's wastewater and the nature of the wastewater, the production wastewater is treated with an oil separator and a grille+air flotation+A2O+Coagulation sedimentation, used for discharge.

Process characteristics:

1. Stability: The processing flow is mature and reliable, and the treated effluent is stable and meets the standard;

2. Progressiveness: advanced treatment process,Strong overall facility integrity;

3. Reliability: After the processing station is built, it is easy to operate and manage, with simple operation and easy entry;

4. Economy: Try to choose low investment and low operating costs;

5. Integrity: The overall process is coordinated and optimized to adapt to the surrounding environmental conditions.
