文摘

Total arsenic concentration was accumulated to 10,661.92 ± 539.63 mg/kg in the AGS.; Volatile arsenic was released at 134.93 ± 6.61 ng/d from the UASB reactor.; Most of the soluble arsenic was in the form of As(III), followed by As(V) and HAPA.; Anaerobic digestion of roxarsone-contaminated wastewater should be well managed.
