NOVELTY - An organosulfate wastewater processing device comprises shell (18), water inlet pipe (1), acid and sulfate reducing area (2), methane area (4), settling zone (6), inner circulation system, first level three phase separator, second level three phase separator, and outside circulation system. The water inlet pipe is located in the shell bottom portion. The first level three phase separator is located in acid and sulfate reducing area and methane production zone. The second level three phase separator is located in methane production area and settling zone.    USE - Organosulfate wastewater processing device.    ADVANTAGE - The device avoids complex process and has low processing cost.    DETAILED DESCRIPTION - Organosulfate wastewater processing device comprises shell (18), water inlet pipe (1), acid and sulfate reducing area (2), methane area (4), settling zone (6), inner circulation system, first level three phase separator, second level three phase separator, and outside circulation system. The water inlet pipe is located in the shell bottom portion. The first level three phase separator is located in acid and sulfate reducing area and methane production zone. The second level three phase separator is located in methane production area and settling zone. The settling zone comprises overflow weir and reactor water outlet. The reactor water outlet is located in shell upper part. An overflow weir is located in the reactor water outlet. The inner circulation system comprises gas liquid separator, discharge pipe, first level rising pipe, second level rising pipe and descending pipe. The gas-liquid separator is located in shell outer side top. The discharge pipe is located in the gas-liquid separator top part. The first level three phase separator is connected to second level rising pipe. The second level three phase separator is connected through descending pipe to methane production zone.
