Typical Case: Epoxy Resin Wastewater Treatment

The company addresses the pain points of epoxy resin wastewater featuring high COD, high salinity and refractory organics. We adopt a combined process of pretreatment for ring destruction and detoxification, biochemical degradation of organics and advanced resource recovery, and have served multiple bisphenol A manufacturers successfully.

Achieve a COD removal rate exceeding 95%. Supporting MVR evaporative crystallization realizes salt resource recovery and reclaimed water reuse. The system operates stably and meets discharge standards long-term, significantly cutting operation and maintenance costs, and enabling enterprises to strike a balance between green low-carbon production and economic benefits.

Detailed Explanation of Chemical Environmental Protection Technologies: Energy Saving and Resource Utilization



Wastewater Treatment — Balancing Energy Conservation and Resource Recovery

● Anaerobic Biogas Production (UASB/IC/EGSB)

Advantages: 0.35 m³ biogas generated per 1 kg COD; sludge yield only 1/5 of aerobic processes

Application: High-concentration organic wastewater (COD>3000 mg/L)

● MBR Membrane Bioreactor

Advantages: Effluent available for reuse; footprint only 1/3 of conventional processes

Application: Sites with limited space and requirements for reclaimed water reuse

● Catalytic Wet Air Oxidation (CWAO)

Advantages: Degrade refractory organics under mild conditions (150–320°C); recyclable catalyst

Application: Pretreatment of fine chemical and pharmaceutical wastewater

● Resin Adsorption & Solvent Recovery

Advantages: Recover high-value solvents such as methanol and acetic acid to turn waste into resources

Application: Wastewater containing recoverable organics

2. Waste Gas Treatment — Priority to Recovery and Guaranteed Compliance

● Regenerative Thermal Oxidizer (RTO)

Advantages: Heat recovery rate over 95%, purification efficiency over 99%; waste heat available for power generation and heating

Application: Continuously discharged waste gas with medium-to-high concentration

● Regenerative Catalytic Oxidation (RCO)

Advantages: Operating temperature 200–400°C; energy consumption reduced by 30–50% compared with RTO

Application: Organic waste gas free of catalyst poisons

● Resin Adsorption and Recovery Technology

Advantages: High selectivity, recovering high-value components containing chlorine and sulfur

Application: Complex waste gas difficult to treat by activated carbon

● Condensation Recovery Technology

Advantages: Direct solvent recovery, low cost and no secondary pollution

Application: High-concentration VOCs (>5000 ppm)

3. Systematic Approaches to Cost Reduction and Efficiency Improvement

🔹 Source Reduction

Optimize processes and implement cleaner production; treatment cost is only 1/3–1/10 of end-of-pipe treatment.

🔹 Resource Recovery

Full recovery of biogas, solvents, salts and reclaimed water to turn waste into valuable resources.

🔹 Cascade Utilization of Energy

Multi-stage reuse of RTO waste heat, steam and condensate water to improve energy self-sufficiency rate.

🔹 Intelligent Operation & Maintenance

AI control combined with digital twin technology cuts chemical costs by 20–40% and minimizes shutdowns.
