Gas chromatogram (the examination of biogas was done when the influent concentrations of COD, ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen were 20821 mg/L, 1503 mg/L, 3917 mg/L, and 1427 mg/L, resp.; the influent pH was 7.78, and the conductivities of the influent and catholyte were 18.01 mS/cm and 7.17 mS/cm, resp.).
