Verwendung von Amino-modifizierten Magnetkügelchen zur Behandlung von Abwässern aus Verzinkungsanlagen

Einführung

Dear zinc plating factory owners and engineers,Are you frequently troubled by the following issues?

Excessive sludge generated by traditional treatment processes, with staggering disposal costs

Limited space, yet sedimentation tanks occupy a vast area Rising chemical consumption and continuously increasing costs Don’t worry! Heute, we continue to introduce this truly powerful cutting-edge technology—theSilica-Based Magnetic Beads Wastewater Treatment Process—Making the wastewater treatment of your galvanizing plant easy and efficient!

1.Detailed Process Flow Illustration

1.1 Quality-Based Pretreatment

• Chromium-containing wastewater: Collected separately and treated using traditional reduction-precipitation (Cr⁶⁺ → Cr³⁺).
• Zinc/nickel-containing wastewater: Directed to an equalization tank for homogenization (no need to adjust pH, saving large amounts of alkali agents!).

1.2 Magnetic Bead Adsorption Reaction

• Amino-modified magnetic beads are added to the reaction tank (5-10 times the heavy metal concentration).
• Stir for 20-30 minutes—the magnetic beads precisely capture Zn²⁺ and Ni²⁺ ions.

1.3 Magnetische Trennung (Core Step)

• Wastewater enters ahigh-gradient magnetic separator (key equipment).
• Beads are fully extracted within 2 Minuten ( 60 times faster than traditional sedimentation!).
• Effluent is crystal clear, with Zn/Ni concentrations<0.5 mg/L.

1.4 Magnetic Bead Regeneration & Resource Recovery

• Beads are regenerated by soaking in dilute HCl (0.1M) for 10 Minuten.
• Beads can be reused≥10 times with consistently high performance.
• High-concentration eluate can undergo electrolytic recovery of zinc/nickel metals (turning waste into treasure).

2.Why Is This a “Breakthrough” Technology?

2.1 Breakthrough Sludge Reduction

Vorteil: Eliminates the need for large inorganic additives (z.B., lime, iron salts), reducing sludge production by70-90%. The minimal remaining sludge mainly comes from chromium pretreatment and resource recovery units, drastically cutting hazardous waste disposal costs.

2.2 High Efficiency & Compactness

Vorteil: Magnetic separation is extremely fast (<2 Minuten), replacing hours-long sedimentation processes and large sedimentation tank systems.Saves over 50% of footprint, making it ideal for space-constrained retrofit projects. High treatment efficiency and strong resistance to hydraulic shock loads.

2.3 Resource Recovery & Economic Benefits

Vorteil: Achieves concentration and recovery of heavy metals, turning waste into valuable resources. Heavy metal recycling is no longer a dream but a direct source of revenue. Water reuse rates are significantly improved.

2.4 Ease of Operation & Automatisierung

Vorteil: Short process flow easily enables full automation (PLC controls pH, bead dosing, regeneration cycles), reducing manual operations and chemical dosing uncertainties. Ensures stable and reliable operation.
