Compact Slaughterhouse Wastewater Treatment Plant 3.5kW-170kW Fully Automatic Operation

10 t/d EO electrochemical wastewater treatment equipment for slaughtering wastewater with high SS, oil & grease, concentration, ammonia nitrogen and pathogens

Quick Details

Slaughterhouse wastewater is a high-concentration organic effluent generated by the meat processing industry, with distinct water quality characteristics and significant treatment challenges. It contains large amounts of blood, grease, meat scraps, offal residues, animal manure, and cleaning agents, resulting in extremely high concentrations of suspended solids, abundant grease (especially emulsified grease), high loads of organic matter (primarily proteins and fats), and ammonia nitrogen. Simultaneously, the wastewater is rich in pathogenic microorganisms such as E. coli, is prone to putrefaction and foul odor, and experiences severe fluctuations and shock loads in water quality. If the traditional "screening - oil separation - air flotation - biological treatment" process is employed, it often faces issues such as incomplete pretreatment leading to biological systems being coated and shocked by grease, sludge bulking, unstable operation, and insufficient removal of characteristic pollutants (e.g., refractory organic matter, color, pathogens), making it difficult to meet increasingly stringent discharge and reuse standards.

Addressing the core treatment difficulties of slaughterhouse wastewater—"high grease, high suspended solids, and high biological contamination"—the CQDHX SERIES EO Electrochemical Oxidation Equipment, developed and manufactured by our company (AA&SS AQUA HITECH CO., LTD.), generates highly oxidizing species in-situ through electrochemical action, such as hydroxyl radicals and active chlorine. This not only efficiently degrades refractory, biodegradable organic matter in the wastewater, such as soluble protein and fat metabolites, but also achieves broad-spectrum, rapid inactivation of pathogenic microorganisms. Its prominent advantage is that the entire operation requires no addition of any chemical agents, fundamentally avoiding potential carcinogenic by-products (e.g., trihalomethanes) from chlorinated disinfectant dosing and the substantial chemical sludge issues from coagulant addition. Furthermore, the process generates no secondary chemical solid waste, achieving a clean and waste-minimized treatment process.

Wastewater first undergoes pretreatment: screens intercept large debris, hydrocyclones remove grit, followed by specially designed oil separators to remove most floating oil. Then, through efficient air flotation (e.g., dissolved air flotation) or coagulation-sedimentation, emulsified oils are thoroughly broken and the vast majority of suspended solids and colloids are removed. This enhanced pretreatment is an absolute prerequisite for ensuring the efficient and stable operation of subsequent electrochemical equipment.

The pretreated wastewater enters the front-end EC Electrochemical Equipment for comprehensive action including deep demulsification, coagulation, and partial oxidation. It efficiently captures residual fine grease particles, colloidal organic matter, and phosphates, and partially degrades sulfides while removing color and odor through redox reactions. This significantly reduces the pollutant load and markedly improves water quality, creating optimal conditions for subsequent deep oxidation.

The supernatant, after treatment and solid-liquid separation, contains primarily dissolved organic pollutants, ammonia nitrogen, and pathogenic bacteria. The wastewater then enters the CQDHX SERIES EO Electrochemical Oxidation Equipment. The electrochemical oxidation process will deeply degrade refractory organic matter remaining in the wastewater (such as certain odorants and colorants). Simultaneously, the highly oxidizing environment it creates instantly kills all pathogenic microorganisms, achieving thorough disinfection and safety assurance for the effluent. Our company's equipment is optimized for the high organic matter and high salinity (from cleaning) characteristics of slaughterhouse wastewater, ensuring it maintains efficient and stable oxidation and disinfection performance even under complex water quality conditions, enabling direct compliance with discharge standards.

The CQDHX SERIES EO Electrochemical Oxidation Equipment, independently produced by our company, simultaneously achieves deep oxidation of pollutants and instantaneous, thorough pathogen inactivation in a clean operation mode without any chemical addition. This not only ensures absolute safety and stable compliance of the effluent but also significantly reduces operational and maintenance complexity, providing a solid and efficient technical equipment guarantee for the cleaner production and sustainable development of the meat processing industry.

For wastewater with special characteristics or unique treatment objectives, our company's engineers provide technical support and solutions.
