The aim of this research it is to show how the biogas anaerobic digestion from treatment of recycled pulp and paper wastewater industry (RPPW) can be a renewable energy. Furthermore, a kinetic study of hydrolyzed COD and productions of methane from UASB digester treating RPPW for the continuous test is established. This will allow to reduce the organic matter deposited in landfills and CO₂ emissions and to find viable solutions to minimize the environmental impact of RPPW. This study analyses the biogas products and energy recovery processes from a thermic and electric point of view from the theoretical equations. Thus, this study evaluated the performance of mesophilic methanogenic up-flow sludge blanket reactors (UASB) operating continuously in single-stage (UASB I). The maximum methane yields were 250.9 mLCH₄/gCOD removed for UASB I, corresponding to 82.7% of the maximum theoretical energy 6.336 kJ/gCOD removed, Methanogenic potential were 4 137 928 m³CH₄/year and electrical energy potential were 510 703 MWh/year. The kinetic study allowed us a hydrolysis rate kh = 0.04 indicates a correct simulation for the UASB digester treatment system for RPPW with an R = 99.668%.

这项研究的目的是表明处理制浆造纸废水行业（RPPW）产生的沼气厌氧消化物如何成为可再生能源。此外，建立了动力学研究水解的COD和UASB消化池处理RPPW的甲烷以进行连续测试。这将减少沉积在垃圾填埋场中的有机物和CO ₂排放并找到可行的解决方案以最大程度减少RPPW的环境影响。这项研究从理论方程式的热学和电学角度分析了沼气产品和能量回收过程。因此，本研究评估了在单级（UASB I）中连续运行的中温产甲烷性上流污泥床反应器（UASB）的性能。UASB I的最大甲烷产量为250.9 mLCH ₄ / gCOD，相当于最大理论能量6.336 kJ / gCOD的82.7％，产甲烷潜力为4137928 m ³ CH ₄/年和电势为510703兆瓦时/年。动力学研究使我们的水解速率kh = 0.04，表明RPPW的UASB消化器处理系统的正确模拟，R = 99.668％。
