本研究的目的是通過使用升流式厭氧污泥床（UASB ）系統在環境溫度下，調查處理性和對二氧化碳和甲烷的製作評價從Carprolactam （ C6H11NO ， CPL）的廢水。該系統的循環比為1： 1和pH值保持在6.8-7.5 。該反應器60天通過2階段有不同的有機碳負荷運轉。這項研究的結果表明，在對4197毫克/升的初始COD獲得93.6 ％的最高去除效率。從UASB產生的氣體主要含有甲烷和二氧化碳。對於進水COD從2897變化到11333mg / L ， COD去除率為70.9-93.6 ％。該甲烷產率是在0.18-0.31升甲烷/ g的COD去除範圍內的範圍。二氧化碳的生產率為0.06-0.14升CO2 / g的COD去除率。這項研究表明UASB的CPL廢水處理的可行性 The objective of this study was to investigate treatability and evaluation of carbon dioxide and methane productions from Carprolactam (C6H11NO, CPL) wastewater by using up-flow anaerobic sludge blanket (UASB) system at ambient temperature. Recycle ratio of the system was 1:1 and pH was maintained at 6.8-7.5. The reactor was operated for 60 days through 2 phases with different organic carbon loading. The results of this study showed that the highest removal efficiency of 93.6% was obtained at an initial COD of 4197 mg/l. The produced gas from UASB mainly contained CH4 and CO2. For influent COD varied from 2897 to 11333mg/l, COD removal was in the range of 70.9-93.6%.The methane production rate was in the range of 0.18-0.31 liter CH4/g COD removal. The carbon dioxide production rate was 0.06-0.14 liter CO2/g COD removal. This study demonstrated the feasibility of UASB for CPL wastewater treatment
