What are the key considerations when selecting water treatment chemicals for slaughterhouses?

Slaughterhouse wastewater treatment requires the following chemicals tailored to its high organic content, grease, and pathogenic characteristics: 1. Flocculants: Cationic polyacrylamide (PAM) adsorbs negatively charged proteins and fats in wastewater. When combined with polyaluminum chloride (PAC), it enhances floc strength, achieving over 80% turbidity removal. 2. Biological agents: Composite bacteria (e.g., Bacillus spp.) and nitrifying bacteria accelerate organic decomposition, reducing COD and ammonia nitrogen. Ammonia nitrogen removal rates reach 60%-90% post-addition. Requires nitrogen and phosphorus nutrients to balance microbial metabolism. 3. Adsorption Decolorizers: Activated carbon adsorbs pigments, odors, and heavy metals, achieving color reduction to <50 times through advanced treatment. Polymer decolorizers target stubborn pigments like hemoglobin, achieving 70%-90% decolorization. 4. Disinfection & Adjustment Agents: Sodium hypochlorite eliminates pathogens, ensuring fecal coliform compliance. Sodium hydroxide neutralizes acidic wastewater to facilitate biochemical reactions. 5. Demulsifiers and Defoamers: Cationic demulsifiers separate oils, while defoamers eliminate aeration tank foam to maintain smooth process flow. Chemical dosages require dynamic adjustment based on water quality to ensure efficient treatment while preventing secondary pollution.
