Electrochemical Wastewater Treatment Equipment: Designed for Treating Sulfur-Containing Petrochemical Wastewater

Quick Details

The sulfur-containing wastewater generated during industrial processes such as oil refining, natural gas processing, and petrochemical manufacturing contains reductive sulfides including hydrogen sulfide, mercaptans, and sulfides. Characterized by strong corrosivity, foul odor, and high toxicity, this type of wastewater also presents multiple challenges to traditional treatment processes: these processes typically involve high consumption of chemical oxidants and operational costs, tend to produce secondary pollutants like sulfur foam or chemical sludge, and suffer from issues such as incomplete treatment and insufficient operational stability.

To address the technical bottlenecks in sulfur-containing wastewater treatment, we have launched our Electrochemical Wastewater Treatment Equipment. Based on electrochemical catalytic oxidation technology, this system is specially designed to efficiently and thoroughly convert various reductive sulfides into harmless sulfates, providing a clean treatment solution that eliminates reliance on external chemical agents and avoids the generation of secondary solid waste.

Core Advantages of the Equipment

Advanced Catalytic Oxidation for Complete Sulfur Conversion

Through direct or indirect electrocatalysis on the electrode surface, the equipment can efficiently and stably oxidize hydrogen sulfide, mercaptans, and other sulfides in wastewater into sulfate ions (SO₄²⁻). The entire process requires no additional dosing of chemical oxidants such as sodium hypochlorite or hydrogen peroxide. This not only eliminates the safety risks and costs associated with the storage, transportation, and dosing of chemical agents, but also fundamentally prevents secondary pollution problems like sulfur foam and precipitated sludge that may arise from conventional chemical oxidation processes, achieving clean conversion and removal of sulfur.

Compact Skid-Mounted Design for Harsh Industrial Environments

Constructed with corrosion-resistant materials and adopting factory pre-assembled skid-mounted modules, the equipment features a highly integrated structure with a small footprint. It can be fully and rapidly deployed in space-constrained or environmentally sensitive areas such as petrochemical parks and refineries, enabling quick installation and commissioning. This design is particularly suitable for the upgrading of existing facilities, the construction of emergency treatment systems, or as a key pretreatment unit for zero-discharge projects.

Flexible Multi-Functional Configuration to Meet Diversified Treatment Objectives

The equipment can be flexibly adapted to different treatment scenarios according to specific water quality and regulatory requirements:

As a High-Efficiency Pretreatment & Desulfurization Core: It efficiently removes sulfides, eliminates foul odors and corrosivity, protects the stable operation of subsequent biochemical or membrane treatment systems, and significantly reduces the overall process load.

As an Advanced Treatment & Discharge Compliance Guarantee Unit: It performs polishing treatment on the effluent from preceding processes, ensuring that key indicators such as total sulfur and COD consistently meet the strictest discharge or reuse standards.

As a Standalone Integrated Treatment System: For high-concentration sulfur-containing process wastewater or small-flow wastewater sources, it can operate independently to achieve full-process high-efficiency purification from influent to direct discharge compliance.

Intelligent Control, Stable Operation & On-Demand Startup

Equipped with an intelligent control system, the equipment can respond to water quality fluctuations in real time and operate fully automatically. With rapid startup capability, it perfectly matches the continuous or intermittent wastewater discharge characteristics of petrochemical production, enabling convenient on-demand operation. The elimination of chemical dosing systems throughout the process significantly reduces operational complexity, safety risks, and long-term comprehensive costs.

Our electrochemical wastewater treatment equipment provides an innovative solution for the petrochemical, natural gas processing, and related energy industries, delivering efficient, cost-effective, safe, and flexibly deployable treatment for sulfur-containing wastewater. It serves as a reliable technological choice to help enterprises achieve stable compliance with discharge standards, reduce environmental risks, improve operational efficiency, and practice green and sustainable development.
