Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a resource treatment system for beef slaughter wastewater. Background Art

[0002] In the process of slaughtering and meat processing, a large amount of water is consumed, and at the same time, wastewater containing pollutants such as blood, grease, hair, meat scraps, livestock and poultry viscera, undigested food and feces must be discharged. In addition, such wastewater also contains a large number of microorganisms that are harmful to human health. Slaughter wastewater comes from pen washing, rinsing, slaughtering and other factory floor washing, scalding, dissection, non-staple food processing, oil washing, etc. If meat processing wastewater is discharged directly without treatment, it will cause serious pollution to the water environment and harm the health of humans and animals.

[0003] There are various treatment methods for slaughterhouse wastewater in the prior art: grid filtration: used to remove large impurities in wastewater, such as hair, fat and broken bones, to prevent subsequent equipment from clogging; sand settling tank: removes sand and inorganic particles in wastewater by gravity sedimentation, reducing the burden on subsequent treatment units; flotation: releases tiny bubbles into the sewage, allowing suspended particles to float to the water surface by attaching to the bubbles, thereby separating and removing grease and suspended matter.

[0004] Coagulation and sedimentation: adding coagulants (such as polyaluminium chloride) to promote the aggregation of fine suspended particles to form larger flocs, which are easy to settle and remove. Chemical oxidation: using strong oxidants such as ozone or hydrogen peroxide to decompose organic pollutants and remove odors. Anaerobic biological treatment: using anaerobic microorganisms to decompose high-concentration organic pollutants and produce biogas as a renewable energy source. Aerobic biological treatment: providing oxygen to sewage through aeration to promote aerobic microorganisms to degrade organic pollutants. Biofilm method: such as biological filters and contact oxidation tanks, using attached and growing microbial films to further degrade organic matter in sewage.

[0005] In the prior art, only impurity removal is required in the primary stage of wastewater treatment, among which raw cattle hair, minced meat, bone residue, grease, etc. need to be processed in the primary stage. Such substances are also the most likely to cause grid blockage, and they need to be cleaned regularly by humans, resulting in slow wastewater treatment efficiency. Summary of the invention
