Electrochemical Wastewater Treatment Equipment: Designed for Treating Pesticide

Product Specification

Electrochemical Wastewater Treatment Equipment: Designed for Treating Pesticide Wastewater Containing Benzene Compounds and Their Derivatives

Quick Details

The wastewater generated during the production of benzene series and derivative pesticides (e.g., phenoxycarboxylic acids, benzoylureas, triazoles, etc.) contains characteristic pollutants such as benzene,  xylene, chlorobenzene, nitrobenzene, aniline and their derivatives. Such wastewater features complex compositions, high toxicity and extremely poor biodegradability; moreover, some of its compounds carry carcinogenic, mutagenic and teratogenic risks, exerting strong inhibitory effects on traditional biological treatment processes. Although conventional chemical oxidation methods deliver certain results, they are generally plagued by problems such as high chemical consumption, elevated operational costs, and secondary pollution caused by toxic intermediates or chemical sludge.

To address the treatment bottlenecks of such highly toxic and refractory pesticide wastewater, we launch our Electrochemical Wastewater Treatment Equipment. Adopting Electrochemical Advanced Oxidation Processes (EAOPs), this system is specially designed to efficiently break down the stable benzene ring structures and achieve complete mineralization of pollutants, providing a reliable technical pathway that is independent of biological processes and produces no secondary solid waste.

Advantages of Our Equipment

Targeted Degradation of Benzene Ring Structures, Enabling Complete Purification

The equipment generates strong oxidizing hydroxyl radicals in situ through electrode reactions, which have an oxidation potential as high as 2.8V. These radicals non-selectively attack and break the stable chemical structures of benzene rings and their derivatives, gradually degrading them into small-molecule organic acids, and ultimately mineralizing them into carbon dioxide and water. No chemical oxidants need to be added during the treatment process, which avoids the massive iron sludge production and salinity accumulation issues caused by the dosing of agents such as Fenton's reagent, achieving clean treatment from the source.

Skid-Mounted Integrated Design, Realizing Rapid Deployment and Commissioning

Adopting integrated, factory-prefabricated skid-mounted modules with a highly compact structure and minimal footprint, the equipment can be transported as a whole to any project site worldwide. It allows for quick installation and system connection, significantly shortening the construction cycle. It is particularly suitable for technical renovation, emergency treatment or environmental compliance upgrading projects of pesticide manufacturers.

Flexible Configuration to Meet Diversified Treatment Objectives

With its powerful oxidation capability, the equipment can be flexibly integrated into your overall water treatment process:

As a core pre-treatment unit: It efficiently eliminates the biological toxicity of wastewater and converts refractory benzene series compounds into biodegradable intermediates, creating safe and stable operating conditions for subsequent biological treatment.

As an advanced treatment and guarantee unit: It performs deep oxidation on the effluent of biological treatment processes, ensuring that key indicators such as COD and characteristic pollutants (e.g., benzene series compounds, AOX, etc.) stably meet the strictest discharge standards.

As an independent treatment system: For high-concentration production mother liquors or wastewater from specific sections, it can form an independent treatment line to realize one-stop purification of wastewater from influent to direct discharge compliance.

Intelligent Control, Safe & User-Friendly, Instant Start-Up & Shutdown

The system features high automation with rapid start-up and shutdown, perfectly adapting to the intermittent and multi-batch production characteristics of the pesticide industry, and enabling flexible on-demand operation. The whole process involves no risks of hazardous chemical addition and storage, ensuring a safer operating environment with simple management and maintenance.

Our electrochemical wastewater treatment equipment provides pesticide chemical enterprises worldwide with an advanced solution that is efficient, eco-friendly, cost-effective and rapidly deployable for highly toxic benzene series wastewater. It is a key technical tool for addressing the challenges of complex pesticide wastewater, meeting stringent environmental requirements, and fulfilling corporate environmental responsibilities.
