Description

technical field [0001] The invention relates to the field of desulfurization wastewater treatment, in particular to an advanced oxidation treatment device and treatment method for desulfurization wastewater in oil and gas fields. Background technique [0002] In recent years, the exploration and development of sour natural gas has been continuously intensified. In the formation water associated with gas production, in addition to sulfide, the COD value in the wastewater is relatively high, and the main components are aromatic compounds and amines. Under normal conditions, the biochemical properties are poor and difficult to degrade , making it difficult to meet the COD standard in the follow-up wastewater treatment. [0003] At present, advanced oxidation technology is mainly used for this kind of wastewater at home and abroad. Advanced oxidation technology is also called deep oxidation technology. It is characterized by the generation of hydroxyl radicals (OH) with strong o...
