The Automatic Ink Waste Water Treatment Machine is an integrated environmental protection equipment designed for printing, packaging, ink production and coating industries. Targeting ink wastewater’s core pain points—complex composition, high chromaticity, high COD value and poor biodegradability—it achieves full-process unattended operation from collection to discharge or reuse via automatic control and multi-process purification. It helps enterprises meet environmental regulations and cut costs through water recycling, becoming essential for green industrial transformation amid tightening global environmental policies.
1. Product Overview & Core Positioning
Ink wastewater, a highly polluting industrial wastewater from equipment cleaning, residual ink discharge and printing plate cleaning, causes severe soil and water pollution if directly discharged, leading to enterprise penalties or shutdowns. This machine integrates physical separation, chemical coagulation, advanced oxidation and biological degradation into a modular design, customizable by water quality and volume. It suits both water-based and oil-based ink wastewater, offering a one-stop treatment solution with strong adaptability and stable effects.
2. Core Working Principle
The machine adopts a multi-stage combined treatment process for optimal purification, with the following key steps:
Pretreatment Stage: Wastewater is collected in a buffer tank, where large impurities are removed by grille filtration and sedimentation to reduce subsequent load and prevent blockages. The automatic dosing system adjusts pH to 6.0-9.0 for subsequent reactions.
Chemical Coagulation Stage: Pretreated wastewater is pumped into the reaction tank, where composite flocculants (e.g., PAC, PAM) are automatically added to form large flocs, separated by sedimentation or air flotation. This removes over 80% of suspended solids, 50% of COD, and significantly reduces chromaticity.
Advanced Oxidation Stage: UV/O₃ or electrocatalytic oxidation breaks down refractory organic substances (e.g., ink resins, solvents) into degradable small molecules, further removing COD (85%-95%) and chromaticity (≥90%).
Biological Degradation Stage (Optional): For higher requirements, a biological module (UASB, MBBR) decomposes macromolecules into CO₂ and water, ensuring effluent meets reuse standards.
Deep Filtration & Post-treatment Stage: Ultrafiltration or activated carbon removes residual impurities and odor. Online water quality detection ensures compliant discharge or recycling for production (e.g., equipment cleaning).
