Mariculture tail water treatment process

The invention belongs to the technical field of water treatment, and particularly relates to a mariculture tail water treatment process. According to the mariculture tail water treatment process, mariculture tail water sequentially passes through a sedimentation tank, a microfilter, an electrode catalytic oxidation module and an adjusting tank from upstream to downstream according to the treatment sequence of the mariculture tail water; the treatment process comprises the following steps: lifting the mariculture tail water to a sedimentation tank, adding a flocculating agent and a coagulant aid, and carrying out flocculent precipitation; filtering the effluent of the sedimentation tank through a microfilter; pumping the filtered water of the microfilter into an electrode catalytic oxidation module, oxidizing to remove organic matters, and oxidizing and reducing ammonia nitrogen and nitrite nitrogen in the water into nitrogen; water discharged from the electrode catalytic oxidation module is pumped into an adj
