Novel single hybrid treatment of continuous clinoptilolite augmented electrocoagulation method integrated with a sequencing batch reactor (SBR) process was introduced to remove highly concentrated ammoniacal nitrogen (NH₃-N) and colour in landfill leachate. First, the crystalline structures of the clinoptilolite were characterised via BET, XRD and XRF analyses, and the effects of different clinoptilolite dosages (13–187 g/L), reaction times (5–70 min) and settling times (5–60 min) on the removal efficiency of the pollutants were investigated. The kinetic mechanism of adsorption was found to correspond to a pseudo-second-order model (R² $\approx$ 1). Next, the regeneration of the spent clinoptilolite was examined using different types of solvents (NaCl, NaOH, HCl), solvent concentrations (0.1–1.0 M), contact times (5–70 min) and reuse numbers (1–5 runs). The highest NH₃-N and colour removal rates were 83% and 95%, respectively, and the optimal removal rates were maintained over 300 min of continuous operations with a total treatment effluent amount exceeding 3750 mL. The most effective removal rates were achieved under optimum operating conditions of 147 g/L clinoptilolite, 60 min of reaction, 35 min of settling, NaCl as the regeneration solvent, 0.5 M solvent concentration, 25 min of contact and four times of reuse cycles. Cost estimations indicated that the overall operating cost for removing NH₃-N and colour using the proposed process is US$8.71/m³/cycle. Thus, the integration of physical, chemical and biological methods into a single process may be a viable option to eliminate concentrated NH₃-N and colour from landfill leachate.

介绍了一种新型的连续斜发沸石增强电凝法与顺序批处理反应器（SBR）工艺相结合的单一混合处理方法，以去除垃圾填埋场渗滤液中的高浓度氨氮（NH ₃ -N）和颜色。首先，通过BET，XRD和XRF分析表征了斜发沸石的晶体结构，以及不同斜发沸石剂量（13–187 g / L），反应时间（5–70分钟）和沉降时间（5–60分钟）的影响）对污染物的去除效率进行了研究。发现吸附的动力学机制与伪二级模型（R ² $\approx$1）。接下来，使用不同类型的溶剂（NaCl，NaOH，HCl），溶剂浓度（0.1-1.0 M），接触时间（5-70分钟）和重复使用次数（1-5次）检查废斜发沸石的再生。最高的NH ₃ -N和脱色率分别为83％和95％，并且在连续运行300分钟的过程中保持了最佳的去除率，总处理废水量超过3750 mL。在147 g / L斜发沸石，60分钟反应，35分钟沉淀，NaCl作为再生溶剂，0.5 M溶剂浓度，25分钟接触和四次重复使用周期的最佳操作条件下，获得了最有效的去除率。成本估算表明，去除NH ₃的总运营成本-N和使用建议工艺的颜色为US $ 8.71 / m ³ /循环。因此，将物理，化学和生物学方法整合到一个过程中可能是消除垃圾渗滤液中浓NH ₃ -N和颜色的可行选择。
