This study investigated the effectiveness of batch electrocoagulation with vibration-induced electrode plates in enhancing the role of gas bubbles in the removal of ammoniacal nitrogen (NH₃-N) from landfill leachate. The experimental setup, which consisted of an electrocoagulation reactor and electrode plates attached to a vibrator motor and connected to a DC-power supply, was employed to determine the effects of the vibration intensity, initial pH, operating time and current intensity on the percentage removal of NH₃-N. The results revealed that the removal of NH₃-N was optimum when the plates vibrated at 2.8 V. Further analysis at this optimum vibration intensity showed that the percentage removal of NH₃-N was enhanced at an initial pH of 10 for both the vibrating and stationary plates. While the treatment with stationary plates showed an increase in the percentage removal of NH₃-N with time, an optimum time of 35 min was achieved for the treatment using the vibration-induced plates. The results showed that the higher the current intensity, the higher the removal of NH₃-N. Electrocoagulation with both the stationary plates and vibration-induced plates was able to achieve 40% and 50% removal of NH₃-N, respectively at a current intensity of 4.5 A. The percentage removal of NH₃-N through electrocoagulation with the vibration-induced electrode plates was found to have improved compared with the use of stationary plates due to the better dispersion of gas bubbles, which reduced the attachment and accumulation of bubbles on the surface of the electrode plates, thereby enhancing the ionic transfer between the plates.

这项研究调查了振动诱导电极板的批量电凝在增强气泡在垃圾渗滤液中去除氨氮（NH ₃ -N）中的作用。实验装置由电凝反应器和连接到振动器电动机并连接到直流电源的电极板组成，用于确定振动强度，初始pH，工作时间和电流强度对去除百分比的影响NH ₃ -N。结果表明，当板在2.8 V振动时，NH ₃ -N的去除效果最佳。在此最佳振动强度下进行的进一步分析表明，NH ₃去除率百分比对于振动板和固定板，在初始pH值为10时-N均得到增强。尽管用固定板进行的处理显示NH ₃ -N去除百分率随时间增加，但使用振动感应板进行处理的最佳时间为35分钟。结果表明，电流强度越高，NH ₃ -N的去除率越高。电与固定板和振动引起的板都能够达到去除NH的40％和50％₃ 4.5 A的电流强度-N，分别百分比去除NH的₃发现与振动板相比，通过振动引起的电极板的电凝法产生的-N具有更好的分散性，这是因为气泡的分散性更好，从而减少了气泡在电极板表面上的附着和积累，从而增强了板之间的离子转移。
