Abstract

The discharge of untreated or inadequately treated wastewater from chemical factories can lead to severe environmental degradation, posing threats to aquatic ecosystems and human health. Initially, the fine chemical factory in Inner Mongolia relied on a conventional method, primarily based on electrochemical oxidation coupled with electro-Fenton oxidation, resulting in chemical oxygen demand (COD) concentrations of approximately 12,000 mg/L. This research contrasts the enhanced wastewater treatment process incorporating electrochemical oxidation with the method of electrochemical oxidation and chemical additives integrated with activated carbon adsorption. The integration of activated carbon led to a substantial improvement in wastewater treatment efficiency. After treatment with the introduction of activated carbon, COD concentrations were reduced to values ranging from 322 mg/L to 622 mg/L across different batches, indicating a reduction of up to 95% compared to the original method. The stark contrast between the two methods underscores the transformative potential of integrating activated carbon adsorption, positioning it as a pivotal solution for chemical factories in Inner Mongolia.
