The toxicity of water rises.And electrochemical process processing waste water has efficient stable, is not necessarily to adding of agent, the advantages of non-secondary pollution,
Have become the hot spot of research applied to field of waste water treatment.
Due to the presence of nitro, it is difficult to remove that this compound structure of chloramphenicol, which is stablized,.The reaction of electrochemical oxidation technology
Efficiency is relatively low, and still has larger toxicity and stability after reacting.If first the nitro on phenyl ring can be reduced to
Then amino is carrying out oxidation processes, so that it may effectively to remove polluter.There is studies have shown that pass through reduction-oxidation before
Mode treatment of Nitrobenzene and the waste water such as chlorophenol, can generate compared to the better treatment effect of independent oxidation technology.And it will be electric
Electronation and electrochemical oxidation combine, and to handle high causing toxicity antibiotic waste water, have not been reported.
