Industrial Park Wastewater Upgrading Solution

Technical Features

• Excellent Removal Performance

Effluent meets or exceeds the Class I discharge standard of the national “Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant” (GB18918-2002).

• Low Treatment Cost

Small footprint, low construction cost, low operating expenses, and long service life.

• Wide Applicability

Suitable for effluent from various wastewater treatment plants, ensuring compliance. Effective removal of complex chemical compounds, especially suitable for degradation and decolorization of industrial park wastewater and colored wastewater.

Technology Principle

1. Micro-electrolysis Technology Overview

Micro-electrolysis is an ideal process for treating high-strength organic wastewater, especially high-salinity, refractory, and highly colored wastewater. It significantly reduces COD and color while improving wastewater biodegradability.

2. Working Mechanism

Without applying external power, micro-electrolysis fillers inside the equipment generate a “galvanic cell” effect. When wastewater flows through, countless micro-galvanic cells with potential differences are formed, using the wastewater as electrolyte. The electrochemical reactions generate current that oxidizes and reduces pollutants, degrading organic contaminants. Active species such as ·OH, H, O, Fe²⁺, and Fe³⁺ participate in redox reactions, breaking the chromophoric or auxochromic groups in colored wastewater, leading to degradation and decolorization. Fe²⁺ is further oxidized to Fe³⁺, whose hydrated forms have strong adsorption and flocculation activity. Particularly after pH adjustment with alkali, ferrous and ferric hydroxide colloids form with superior flocculation capabilities, aggregating dispersed particles, metal ions, and organic macromolecules. This process integrates electrochemical, redox, physical, and flocculation-sedimentation effects for efficient treatment.

Applications

1、Pretreatment of high-strength, refractory, toxic organic wastewater (e.g., pharmaceutical, petrochemical, coking, coal chemical industries) to remove COD, ammonia nitrogen, and color, enhancing biodegradability.

2、Removal of heavy metals and organic pollutants from wastewater containing heavy metal ions (e.g., electroplating, PCB manufacturing, mining, smelting), stabilizing effluent quality and ensuring stable operation of subsequent biochemical systems.

3、Pretreatment of low-COD, refractory wastewater in industrial parks (pharmaceutical, chemical, electroplating, PCB) to improve biodegradability and ensure compliant discharge.

4、Suitable for upgrading existing wastewater treatment stations with low operating costs, supporting energy-saving and emission reduction goals with a broad market potential.
