Advanced Oxidation Technology For Removing Phenol In Wastewater And Its Concept Design Research

Phenolic wastewater is a kind of organic wastewater containing phenols and its derivatives. It is highly toxic and difficult to be degraded. It has attracted the attention of the wastewater treatment field. Fenton oxidation technology is a new branch of advanced oxidation technology, and shows good application prospect in the treatment of phenol wastewater. Heterogeneous Fenton oxidation technology is used to replace the solution of Fe2+ with iron containing solid catalyst, which has high oxidation efficiency, low H2O2 consumption, pH wide application range and can be recycled. Mental-organic frameworks(MOFs) is a kind of new porous material that has a broad application prospect, it can make the materials with various type of microscale skeleton neat hole structure, large specific surface area and porosity and small solid density. Therefore, MOFs has been becoming the current hot research topic in the field of material as well as in the gas storage, adsorption separation, photoelectric catalysis, ion exchange, biological activity.At present, MOFs is used for wastewater treatment with little researches and applications. Due to its excellent characteristics, it provides a new direction for the wastewater treatment especially heterogeneous Fenton technology. In addition, as a new type of functional materials, graphene is used for various fields and also provides new research in this paper.Firstly, prepared three different catalyst using activated carbon, graphite, graphene oxide as a carriers. Then, compare these catalysts effect on adsorption and degradation of phenol. Result showed the catalyst had good effect on the removal of phenol.Then, prepared Fe-BTC catalyst using 1,3,5-three benzoic acid, FeSO4·7H2O and HNO3 as raw material by hydrothermal synthesis method and characterized it. Then it was applied to phenol wastewater treatment, examining its effect factors on the degradation of phenol wastewater including the material liquid initial pH, catalyst dosage, reaction time, the concentration of waste water. The optimum reaction conditions were explored.Finally, the result of the optimum conditions was applied to industrial design process to ideal with an annual output of thousand tons of wastewater. The result of scale-up concept design has showed a potential application value.
