Sewage treatment device with deep oxidation tank coupled with anaerobic tank

The utility model relates to a sewage treatment device with a deep oxidation tank coupled with an anaerobic tank. The sewage treatment device consists of a deep oxidation tank system and an anaerobic decomposition tank, the deep oxidation tank system comprises a catalytic oxidation reaction tank group, an ozone supply pipe and a hydrogen peroxide-sewage premixing sample injection pipe; the catalytic oxidation reaction tank group comprises at least one reaction tank communicated through an overflow wall; an ozone supply pipe introduces ozone from the bottom of the reaction tank; the hydrogen peroxide-sewage pre-mixing sample introduction pipe is used for feeding sewage mixed with hydrogen peroxide into the bottom of the reaction tank at the initial position; the reaction tank is filled with an oxidation catalysis molecular sieve modified by a metal oxide; the anaerobic decomposition tank comprises an anaerobic decomposition tank which is arranged at the downstream of the reaction tank at the tail end position
