Coal Chemical Industrial Wastewater Treatment Equipment For Treating High Phenol / Ammonia Wastewater

Electrochemical Wastewater Treatment Equipment: Designed for Treating High-Phenol and Ammonia Coal Chemical Wastewater

Quick Details

The high-phenol and ammonia wastewater generated during coal chemical production processes (e.g., coal gasification and coking wastewater) is characterized by its complex composition, including high concentrations of phenolic compounds (such as phenol, cresol, and polyhydric phenol), high ammonia nitrogen content, ultra-high COD levels, as well as cyanides and oils. This type of wastewater exhibits strong toxicity and significant biological inhibition.

To address the comprehensive treatment challenges of high-phenol and ammonia coal chemical wastewater, we have launched our Electrochemical Wastewater Treatment Equipment. Integrating synergistic multi-effect technologies including electrochemical oxidation and reduction, this system is specially optimized for the simultaneous advanced degradation of phenolic pollutants and enhanced ammonia nitrogen conversion. It provides an intensive treatment solution featuring a short process flow, no reliance on complex chemical dosing, and zero generation of secondary hazardous waste.

Core Advantages of the Equipment

Synergistic Treatment of Phenol and Ammonia to Simplify Process Flow

By establishing an electrochemical redox environment, the equipment can efficiently degrade various phenolic substances. Meanwhile, by adjusting pH and reaction conditions, it promotes the conversion and separation of free ammonia. The system eliminates the need for continuous dosing of large quantities of chemical oxidants (e.g., hydrogen peroxide) or acid-base agents for cumbersome pretreatment and conditioning, thereby avoiding the production of chemical sludge and high-salt wastewater. It simplifies the treatment process from the source and achieves synergistic enhancement of phenol removal and ammonia nitrogen control.

Skid-Mounted Modular Integration for Significant Footprint and Investment Savings

Adopting factory-prefabricated, functionally integrated skid-mounted modules, the equipment highly integrates core treatment functions that traditionally require multiple structural units, reducing the occupied area by more than 50%. The equipment can be fully and rapidly delivered to project sites, greatly shortening the construction cycle. It is particularly suitable for the upgrading and expansion of existing wastewater treatment plants, supporting newly-built projects, or serving as a key pretreatment unit for zero-discharge systems.

Flexible Multi-Functional Configuration to Precisely Match Different Treatment Stages

According to influent water quality and final disposal targets, the equipment can be flexibly deployed in different process links:

As a High-Efficiency Enhanced Pretreatment Core: It rapidly and effectively degrades toxic phenols, breaks down cyanides, and realizes preliminary separation and regulation of ammonia nitrogen. This significantly reduces the toxic load and nitrogen removal pressure of subsequent biochemical systems, ensuring the stable operation of biological treatment units.

As an Advanced Treatment & Discharge Compliance Guarantee Unit: It performs advanced oxidation on the effluent from biochemical processes, ensuring that key indicators such as total phenols, COD, and ammonia nitrogen consistently meet the stringent influent requirements for direct discharge or membrane concentration systems.

As a Standalone Treatment System: For certain high-concentration phenol-ammonia wastewater or small-to-medium flow scenarios, it can be configured as an independent, short-process treatment line to achieve one-stop purification from influent to stable discharge compliance.

Intelligent Control, Stable Operation & Convenient Management

Equipped with an intelligent control system, the equipment can precisely regulate key parameters such as potential and pH, adapting to the complex fluctuations of coal chemical wastewater quality. With rapid startup capability, it can handle intermittent or continuous discharge modes, enabling flexible on-demand operation. The process significantly reduces or even eliminates the need for chemical dosing, which not only drastically cuts operational costs and safety risks, but also completely relieves the burden of hazardous chemical management and hazardous waste disposal.

Our electrochemical wastewater treatment equipment provides an innovative solution for the modern coal chemical and coking industries, delivering efficient synergistic treatment, compact process flow, cost-effectiveness, reliability, and rapid deployment for high-phenol and ammonia wastewater. It serves as a reliable technological choice to help enterprises achieve stable wastewater discharge compliance, reduce the life-cycle treatment costs, break through environmental protection bottlenecks, and drive green and low-carbon transformation.
