Description
Technical Field
The invention belongs to the technical field of preparation of Fenton catalysts, and particularly relates to a manganese oxide nanowire-supported ferroferric oxide magnetic Fenton catalyst, and a one-step synthesis method and application thereof.
Background
The information disclosed in this background of the invention is only for enhancement of understanding of the general background of the invention and is not necessarily to be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
At present, the water pollution condition in China is becoming more and more serious, in sewage treatment, high-concentration organic wastewater generated in the production processes of chemical engineering, pesticides, biological medicines, textiles and the like is a technical problem of sewage treatment technology, and the water pollution can seriously influence industrial production. First, water contamination can lead to fouling of equipment. Scaling is a phenomenon that is not beneficial to the equipment and can cause great loss to production. For example, heat exchange devices are used in almost all processes where, if the water entering the heat exchange device is of poor quality, some solid deposits may form on the heated surfaces that come into contact with the water after a period of operation. Scaling is a significant hazard to heat exchangers because metals have many times higher thermal conductivities than scale, and scale is very likely to form in tubes with high thermal loads. The metal pipe wall temperature of the scaling part is overhigh, the metal strength is reduced, and thus, serious accidents such as pipe explosion and the like are easy to happen under the action of the pressure in the pipe during production and operation. Scaling not only compromises safe operation, but also greatly reduces the economics of industrial production. And water pollution can also cause corrosion of equipment. If the water quality is poor, metal parts of operating equipment are easy to corrode, the corrosion not only shortens the service life of the equipment and causes economic loss, but also the products of metal corrosion fall into water, impurities in the water are increased, the scaling phenomenon on the heated surface with high heat load is more serious, new scaling continues to accelerate corrosion, and the vicious circle can quickly cause a pipe explosion event.
The Fenton catalytic method is widely used in sewage treatment in the industry because of the advantages of simple oxidation mechanism, high reaction speed, low cost and the like, and the research of the Fenton reaction can be traced back to the last century and has been in the past century. Fenton reaction mainly utilizes H 2 O 2 In the presence of Fe 2+ /Fe 3+ The organic matter is degraded into micromolecules through the strong oxidizing property of the hydroxyl radicals, or is directly mineralized and converted into carbon dioxide and water, so that the requirement of subsequent biological treatment is met, the method is suitable for oxidation treatment of organic wastewater which is difficult to degrade biologically or difficult to solve by common chemical oxidation, and the difficultly-degraded organic matter which cannot be removed by the traditional water treatment technology can be effectively removed. However, the traditional fenton catalytic method can only carry out the reaction in a narrow pH range, and other problems still cannot be overcome, such as the catalyst cannot be recycled after being used.
Compared with the traditional Fenton catalytic method, the novel heterogeneous Fenton catalytic technology solves the problems existing in the traditional catalytic method, has the advantages of wide pH working range, no by-product in the reaction process and the like, and is more and more concerned and more emphasized. In the heterogeneous Fenton catalytic technology, metal oxides (cerium oxide, manganese oxide and cobalt oxide) are used as catalysts, so that stable aromatic ring structures in high-concentration organic pollutants are destroyed, biodegradable micromolecular organic matters such as alcohol, aldehyde, acid or ketone, carboxylic acid and the like are gradually generated, and then other treatments such as subsequent biochemical degradation and the like are carried out. Ferroferric oxide and manganese oxide are typical heterogeneous fenton catalysts. Although the catalytic performance of the Fenton reaction is higher than that of ferroferric oxide, the manganese oxide used in sewage treatment cannot be recycled by a simple magnetic separation method like the ferroferric oxide, and the manganese oxide can be recycled by filtration or centrifugation, so that the recycling method has higher cost in industrial production, and the recycling efficiency is low compared with the magnetic separation method, thereby hindering the practical application of the manganese oxide as a Fenton reaction catalyst in the treatment of high-concentration organic wastewater. Ferrous ions in the ferroferric oxide catalyst can generate a chain reaction with hydrogen peroxide to catalyze the generation of hydroxyl radicals and start a Fenton reaction, and ferric ions generated in the reaction process are fixed on the ferroferric oxide and are not dissolved out, so that the ferrous sludge is not generated like other ferrous catalysts. More importantly, the ferroferric oxide has magnetism, and as is well known, the magnetic nanoparticles have porosity, can provide larger specific surface area and more active sites in the reaction process, and are easy to separate, recycle and reuse by a magnet due to the magnetism. Therefore, although the catalytic performance of ferroferric oxide is much poorer than that of manganese oxide, ferroferric oxide is still considered to be a promising adsorbent and catalyst carrier, for example, in the ferroferric oxide and manganese dioxide composite fenton catalyst and the preparation method thereof disclosed in patent document 201711079571.9, ferroferric oxide and manganese dioxide are supported in natural diatomite to form a three-layer structure, however, the diatomite is easy to fall off during the fenton reaction.
