Through its water quality source, we can know that the blood in the wastewater mainly contains liquid, oil, broken meat, bone residue, hair and feces, etc. The wastewater is brown-red and has a strong odor. Organic suspended solids are high in content and easy to be corrupted. Dissolved oxygen in water will be consumed when discharged into the water body, which will destroy the ecosystem and pollute the environment. It has the characteristics of large amount of water, uneven drainage, high concentration, more impurities and suspended solids, and good biodegradability.
Organic suspended solids are high in content and easy to be corrupted. Dissolved oxygen in water will be consumed when discharged into the water body, which will destroy the ecosystem and pollute the environment.
In the process of slaughtering and meat processing, a large amount of water is consumed. At the same time, wastewater containing pollutants such as blood, grease, wool, meat scraps, visceral impurities of livestock and poultry, undigested food and excrement is eliminated. Moreover, there are a large number of microorganisms harmful to human health in this kind of wastewater. Meat processing wastewater, if discharged directly without treatment, will cause serious pollution to the water environment and harm to human and animal health.
Most of the pollutants in meat processing wastewater belong to easily biodegradable organic substances. After they are discharged into the water body, they will rapidly consume dissolved oxygen in the water, resulting in the death of fish and aquatic organisms due to hypoxia. Because of hypoxia, the water body will also be transformed into anaerobic state, which will deteriorate the water quality, produce odor and affect sanitation. At the same time, pathogenic microorganisms in wastewater will multiply in large quantities and endanger people's health. It is necessary to treat slaughter meat processing wastewater and remove its pollution to protect the ecological environment and human health.
