Coal Chemical Wastewater Treatment Plant , Semi Coke Wastewater Pretreatment Equipment

Electrochemical Wastewater Treatment Equipment: Designed for Treating Semi-Coke Coal Chemical Wastewater

Quick Details

The wastewater generated during the production of semi-coke (blue charcoal) is characterized by high concentrations of phenols, ammonia nitrogen, high COD, high chroma, and refractory organic substances such as tar. It is a typical type of industrial wastewater featuring high pollution, high toxicity, and difficult treatment.

To address the core challenges in semi-coke wastewater treatment, we have launched our Electrochemical Wastewater Treatment Equipment. Adopting high-efficiency electrochemical catalytic oxidation and synergistic treatment technologies, this system is specially optimized for degrading characteristic pollutants such as phenols and tar, as well as improving wastewater biodegradability. It provides a clean, high-efficiency, and stable treatment solution that eliminates the need for complex chemical pretreatment and avoids the generation of secondary solid waste.

Core Advantages of the Equipment for Semi-Coke Wastewater Treatment

Targeted Degradation of Characteristic Pollutants with Synchronous Demulsification and Decolorization

Through electrochemical reactions, the equipment efficiently generates strong oxidizing species such as hydroxyl radicals, which can selectively attack and degrade characteristic pollutants including phenol and polyhydric phenol. Meanwhile, it achieves high-efficiency demulsification and decolorization of emulsified oil and colored substances. The entire process requires no addition of chemical demulsifiers, oxidants, or decolorants, eliminating the generation of chemical sludge and the risks associated with hazardous chemical dosing at the source, and realizing clean pretreatment.

Skid-Mounted Modular Integration for Significant Footprint and Investment Savings

Employing factory-prefabricated skid-mounted modular design, the equipment features a highly compact structure with a footprint of less than 40% of that of traditional physicochemical pretreatment systems. It can be fully and rapidly transported to production sites for quick installation and commissioning. This design is particularly suitable for semi-coke enterprises undertaking environmental protection facility upgrades or supporting newly-built projects, significantly shortening the construction cycle and reducing infrastructure investment.

Flexible Multi-Functional Configuration to Meet Diverse Treatment Requirements

According to water quality conditions and treatment targets, the equipment can be flexibly applied to different treatment stages:

As a High-Efficiency Core Pretreatment Unit: It efficiently removes toxic phenols and reduces oil content, significantly improving wastewater biodegradability and creating stable, high-efficiency operating conditions for subsequent biological treatment systems.

As an Advanced Treatment Guarantee Unit: It performs advanced oxidation on the effluent from biochemical processes, ensuring that key indicators such as COD, chroma, and ammonia nitrogen consistently meet strict discharge or reuse standards.

As a Standalone Treatment System: For wastewater from specific production sections or small-scale production needs, it can operate independently to achieve one-stop purification from influent to direct discharge compliance.

Intelligent Control, Stable Operation & Convenient, High-Efficiency Operation

Equipped with an advanced intelligent control system, the equipment can automatically optimize operating parameters based on water quality changes. It features rapid startup capability, perfectly adapting to the continuous or intermittent wastewater discharge characteristics of semi-coke production, and truly realizing on-demand operation. The process design without chemical dosing greatly reduces the complexity of daily operation and management as well as long-term operational costs.

Our electrochemical wastewater treatment equipment provides an innovative, high-efficiency, cost-effective, clean, and rapidly deployable wastewater treatment solution for the semi-coke and coal chemical industries. This technology can effectively help enterprises achieve environmental compliance, reduce comprehensive treatment costs, enhance operational stability, and serve as a reliable technological choice to drive the green transformation and upgrading of the industry.
