Slaughter wastewater must be treated to meet national environmental protection requirements due to its high pollutant content.

Slaughter wastewater contains a large amount of organic matter, which is suitable for using aerobic bacteria to decompose BOD and COD in the wastewater, and then using an air flotation machine to remove SS from the water.

This process consumes less water during operation, mainly for mixing chemicals and office laboratory water. The flushing water uses treated water, and the daily water consumption can be met by the water supply facilities. The drainage can be discharged nearby. This project is a sewage treatment project for slaughterhouses. While treating wastewater, the project itself also generates certain pollutants, such as sediment sludge and waste residue. To avoid secondary pollution, sludge can be used as organic fertilizer after being dehydrated or dried by a sludge dewatering machine.
