The aim of the present study is to evaluate the application of high rate integrated anaerobic-aerobic/biogranular activated carbon sequencing batch reactor (IAnA-BioGACSBR) to treat raw strong leachate from open dumping of municipal solid waste. The influence of two important and effective independent variables, COD concentrations and volumetric filling rate with GAC, onto the leachate treatment were investigated. Three responses such as TKN, BOD and COD were considered for evaluating the interaction of parameters. The results showed that maximum BOD removal of 98.9% in anaerobic zone and 99% in aerobic zone was obtained at the highest values of COD (30000 mg/L) and filling ratio (50%). The highest values of COD removal efficiency were found to be 98.54% and 98%, at COD rate of 10000 mg/L and GAC of 35%, respectively. The highest removal values of TKN was 77.2% and 78.9% in anaerobic and aerobic zone, respectively. Under optimal conditions, compared with the SBR and the GAC-SBR performances, results reveal that the application of the GAC-SBR has shown better effluent characteristics. Based on the results, it can be asserted that the application of the high rate IAnA-BioGACSBR for the treatment of biodegradable landfill leachate was more effective.
本研究旨在评估高通量集成厌氧-好氧/生物颗粒活性炭序批式反应器（IAnA-BioGACSBR）在处理来自城市固体废物露天倾倒的原始强渗滤液方面的应用。考察了两个重要且有效的独立变量，即 COD 浓度和 GAC 填充率，对渗滤液处理的影响。考虑了三个响应，即 TKN、BOD 和 COD，以评估参数的相互作用。结果表明，在最高 COD（30000 mg/L）和填充率（50%）值下，在厌氧区获得了最高的 BOD 去除率（98.9%），在好氧区获得了最高的 BOD 去除率（99%）。在 COD 速率为 10000 mg/L 和 GAC 为 35%时，发现 COD 去除效率的最高值分别为 98.54%和 98%。在厌氧区和好氧区，TKN 的最高去除值分别为 77.2%和 78.9%。在最佳条件下，与 SBR 和 GAC-SBR 的性能相比，结果表明，GAC-SBR 的应用具有更好的出水特性。基于这些结果，可以断言，高通量 IAnA-BioGACSBR 应用于可生物降解垃圾渗滤液的处理更为有效。
