The environment surrounding final disposal sites has changed significantly over the past few years. As a result of the upgrading of incineration facilities, incineration residues account for more than 78% of the landfill volume, resulting in a highly saline and highly alkaline environment. For this reason, physical-chemical rather than biological treatment has become the main leachate treatment method. However, there are also problems with the treatment of persistent organic matter and nitrogen derived from organic chelates used in fly ash stabilisers. Against this background, the authors have focused on the possibility of decomposing persistent organic matter by electrolysis and have conducted empirical studies. In this study, it was found that the introduction of an electrical treatment system centred on electrolysis and electrodialysis membranes, instead of the current leachate treatment system, can significantly shorten the treatment process and reduce electricity costs.
