The coconut processing industry generates a significant amount of liquid waste. New technologies targeting the treatment of industrial effluents have emerged, including advanced oxidation processes, the Fenton reaction, and electrochemical processes, which produce strong oxidizing species to remove organic matter. In this study we combined the Fenton reaction and electrochemical process to treat wastewater generated by the coconut industry. We prepared a synthetic wastewater consisting of a mixture of coconut milk and water and assessed how the Fenton reagents' concentration, the cathode material, the current density, and the implementation of associated technologies affect its treatment. Electrochemical treatment followed by the Fenton reaction diminished turbidity and chemical oxygen demand (COD) by 85 and 95%, respectively. The Fenton reaction followed by the electrochemical process reduced turbidity and COD by 93 and 85%, respectively. Therefore, a combination of the Fenton and electrochemical technologies can effectively treat the effluent from the coconut processing industry.
椰子加工行业会产生大量的液态废物。现在已经出现了一些针对工业废水处理的新技术，包括高级氧化工艺、芬顿反应和电化学工艺，它们会产生强氧化剂来去除有机物。在这项研究中，我们将芬顿反应和电化学工艺结合起来处理椰子加工行业产生的废水。我们制备了一种由椰奶和水混合而成的合成废水，并评估了芬顿试剂的浓度、阴极材料、电流密度以及相关技术的应用如何影响其处理效果。电化学处理后再进行芬顿反应，可分别使浊度和化学需氧量（COD）降低 85%和 95%。而芬顿反应后再进行电化学处理，可分别使浊度和 COD 降低 93%和 85%。因此，芬顿和电化学技术的组合可以有效地处理椰子加工行业的废水。
