Slaughtering wastewater is generally reddish brown, with a large change in water quality and bad smell. It contains a large amount of blood, grease, wool, meat, bone, internal debris, undigested food, feces, etc. It is a typical "three-high" waste water. If it enters the biochemical treatment stage, it will seriously affect the operation of the equipment and the treatment effect of waste water. Therefore, it’s very important to pay attention to the pretreatment of slaughtering wastewater.
