Abstract

Electrocoagulation (EC) is an effective and emerging technique for the treatment of various types of wastewaters due to its unique adaptability, simple design, low cost, and environmental compatibility. This technique uses direct current between the metal electrodes immersed in the wastewater, which leads to the dissolution of electrode plates, releasing metal ions that destabilize and coagulate contaminants for subsequent removal. The performance of EC is influenced by various factors, including electrode material, pH, current density, temperature, and time. Despite its advantages, large-scale industrial application of EC requires further optimization of these key parameters and the development of reliable process models. This manuscript also reviews recent advancements in EC technology, such as EC-biological treatment, EC-chemical coagulation, photovoltaic-EC, and EC-membrane hybrid systems. Owing to its high pollutant removal efficiency, environmental sustainability, ease of operation, and relatively low automation cost, EC shows strong potential as a future wastewater treatment technology.

电絮凝法处理废水

电絮凝技术具有适应性强、设计简单、成本低、环保等优点，是一种有效的新型污水处理技术。该技术利用浸在废水中的金属电极之间的直流电，导致电极板溶解，释放金属离子，使污染物不稳定并凝固，以便随后去除。电极材料、pH值、电流密度、温度、时间等因素对电催化性能的影响很大。尽管有其优势，但电子商务的大规模工业应用需要进一步优化这些关键参数并开发可靠的过程模型。本文还回顾了EC技术的最新进展，如EC-生物处理，EC-化学混凝，光伏-EC和EC-膜混合系统。由于其去除污染物效率高、环境可持续性好、操作简便、自动化成本相对较低等优点，EC作为未来的污水处理技术具有很强的潜力。
