Characteristics and Difficulties of slaughterhouse wastewater treatment

The wastewater from slaughtering sheep is generally reddish-brown with a foul smell, containing a large amount of blood, grease, hair, meat fragments, bone fragments,内脏impurities, undigested food, feces, and other pollutants, leading to high levels of organic matter and suspended solids.

Slaughter wastewater solutions and treatment process features

The ammonia-nitrogen concentration in slaughter wastewater is high, so the impact and removal of ammonia-nitrogen on wastewater treatment should be fully considered in the process design.

Processed Effect

The wastewater treatment system designed for this sheep slaughterhouse has good effluent water quality, with the main water quality indicators meeting the discharge standards of "Emission Standards for Water Pollutants from Meat Processing Industry" GB13457-1992 (for animal slaughtering and processing). It can effectively adapt to fluctuating influent water quality and solve complex water quality issues. Based on the actual requirements and the design of the A/O process (格栅+biological contact oxidation+sedimentation+electrolytic disinfection), the system emphasizes the sterilization and disinfection of wastewater and sludge to enhance water quality, meet discharge standards, and provide a low-cost operation with excellent treatment performance and convenient daily operation.
