Integrated Textile Wastewater Treatment Plant 200V-400V For Wastewater Treatment

Integrated Textile Wastewater Treatment Equipment: Used for wastewater treatment in various processes including textile printing and dyeing, sizing-dyeing/washing, printing/dyeing and finishing.

Quick Details

For the industrial wastewater of the textile printing and dyeing industry—characterized by complex components, high chromaticity, high toxicity and poor biodegradability—we provide professionally customized integrated biological treatment systems. The equipment deeply integrates high-efficiency physicochemical pretreatment and advanced bioaugmentation technology, and is specially designed to address the treatment challenges of various dyes, auxiliaries and slurries. It ensures that wastewater stably meets the strictest emission standards worldwide, and helps enterprises achieve significant water conservation and cost optimization.

Textile printing and dyeing wastewater is a typical type of complex industrial wastewater, with the following characteristics:

High Chromaticity and Poor Biodegradability: It contains large amounts of residual dyes (reactive, disperse, direct, vat dyes, etc.), resulting in extremely high chromaticity. Moreover, the molecular structure of many dyes is stable and difficult to be degraded by ordinary microorganisms.

High Concentration and Complex Composition: Rich in slurries (PVA, starch), various auxiliaries (wetting agents, leveling agents, finishing agents), alkaline agents and heavy metal ions, it features high COD (Chemical Oxygen Demand) and TDS (Total Dissolved Solids) levels, along with poor biodegradability (B/C ratio).

Severe Fluctuations in Water Quality and Quantity: Discharge is intermittent and highly shock-loaded, varying with production orders, fabric types and dyeing processes.

Environmental Toxicity Risk: Some dye intermediates and auxiliaries are biotoxic, which may affect the stability of conventional biological treatment systems.

This system adopts a targeted combined process of high-efficiency pretreatment for detoxification and solubilization + bioaugmentation with special microbial flora + advanced decolorization assurance, ensuring the efficient removal of characteristic pollutants.

Water Quality Equalization and Neutralization: An equalization tank and an automatic pH control system are installed to balance drastic fluctuations in water quality, creating stable conditions for subsequent treatment processes.

Key Physicochemical Pretreatment: Integrating electrochemical oxidation technology and high-efficiency coagulation air flotation. Oxidation effectively destroys dye chromophores, breaks the chains of complex organic matter, improves wastewater biodegradability, and synergistically removes partial chromaticity and suspended solids.

Salt-tolerant and Toxicity-resistant Special Microbial Flora: The system is dosed with and domesticates exclusive high-efficiency bacterial agents targeting refractory substances such as dyes and PVA, significantly enhancing the system's salt tolerance, toxicity resistance and degradation efficiency.

Combination of Multi-stage Biochemical Processes: Adopting the "hydrolysis acidification + multi-stage A/O (Anoxic/Oxic)" process or the "MBR (Membrane Bioreactor)" process. The hydrolysis acidification stage further converts macromolecular organic matter into small molecules; under the action of special microbial flora and optimized control, the subsequent aerobic stage thoroughly degrades pollutants and simultaneously achieves efficient nitrogen removal.

Exclusive Advanced Treatment: After biochemical treatment, the effluent is fed into a biological activated carbon filter, a special oxidation unit or a high-efficiency coagulation unit as the final guarantee. This ensures that indicators such as effluent chromaticity and COD stably meet discharge standards, satisfying the requirements for clear and transparent water suitable for reuse or discharge.

Intelligent Dosing and Control System: Based on feedback data from online colorimeters and COD monitors, it precisely controls the dosage of oxidants and coagulants, minimizing chemical costs while ensuring treatment effectiveness.

Core Product Advantages and Customer Value

Excellent Decolorization and COD Removal Performance: Specifically designed to break down dye molecules and textile chemicals, the system achieves a chromaticity removal rate of over 95%, producing clear effluent with stably up-to-standard COD levels.

Strong Shock Resistance and Stability: Strengthened design targeting the variable water quality characteristics of textile wastewater. Through the triple protection of "equalization + pretreatment + special bacterial agents", it ensures stable system operation and reliable effluent quality even during production fluctuations.

Significant Water Conservation and Cost Reduction Benefits: The high-quality effluent can be directly reused in non-critical production processes (such as rinsing and floor cleaning), greatly reducing freshwater consumption and water costs. High-efficiency biological treatment also reduces reliance on chemicals, cutting down overall operating costs.

High Integration and Intelligent Operation & Maintenance: Modular and compact design adapts to space constraints in factories. Equipped with a fully automatic intelligent control system and a remote IoT platform, it realizes unattended operation, remote monitoring and early warning, greatly reducing dependence on professional operation and maintenance personnel.

Enhanced Corporate Environmental Brand Value: Enabling customers to easily comply with environmental inspections, meet the environmental compliance requirements of international brand suppliers, and enhance their market competitiveness and green corporate image.
