The paper industry is a major environmental polluter due to paper waste sludge (PWS), often disposed of in hazardous ways. The techniques are employed to disposing of PWS are posing significant environmental hazards and risks to well-being. This study aims to evaluate PWS as a potential replacement for commercial adsorbents like AC and ZEO in treating stabilized leachate. Contact angle analysis of PWS was 92.60°, reveals that PWS to be hydrophobic. Batch adsorption experiments were conducted with parameters set at 200 rpm stirring speed, 120 min contact time, and pH 7. Optimal conditions for COD and NH₃–N removal were identified at 120 min contact time, 200 rpm stirring speed, pH 7, and 2.0 g PWS ratio. Removal percentages for COD and NH₃–N were 62% and 52%, respectively. Based on the results of the isotherm and kinetic studies, it was observed that the Langmuir and Pseudo second order (PSO) model exhibited greater suitability compared to the Freundlich and Pseudo first order (PFO) model, as indicated by higher values of R-squared (R²). The R-squared of Langmuir for COD and NH₃–N were 0.9949 and 0.9919 and for Freundlich model were 0.9855 and 0.9828 respectively. Whereas the R-squared of PFO for COD and NH₃–N were 0.9875 and 0.8883 and for PSO were 0.9987 and 0.9909 respectively.

由于造纸废污泥 (PWS) 经常以危险的方式处置，造纸工业成为主要的环境污染源。用于处理 PWS 的技术对环境造成了严重的危害和健康风险。本研究旨在评估 PWS 作为 AC 和 ZEO 等商用吸附剂处理稳定渗滤液的潜在替代品。 PWS 的接触角分析为 92.60°，表明 PWS 具有疏水性。批量吸附实验的参数设置为 200 rpm 搅拌速度、120 分钟接触时间和 pH 7。确定了 COD 和 NH ₃ –N 去除的最佳条件为 120 分钟接触时间、200 rpm 搅拌速度、pH 7 和 pH 值。 2.0克PWS比例。 COD和NH ₃ –N的去除率分别为62%和52%。根据等温线和动力学研究的结果，可以看出，与 Freundlich 和伪一阶 (PFO) 模型相比，Langmuir 和伪二阶 (PSO) 模型表现出更大的适用性，如更高的 R 平方值所示（R ²）。 COD 和 NH ₃ –N的 Langmuir R 平方分别为 0.9949 和 0.9919，Freundlich 模型的 R 平方分别为 0.9855 和 0.9828。而 COD 和 NH ₃ –N的 PFO 的 R 平方分别为 0.9875 和 0.8883，PSO 的 R 平方分别为 0.9987 和 0.9909。
