Problems solved by technology

These traditional methods have the advantages of convenient and simple operation, but they do not solve the problem fundamentally, causing pollution to soil, water body, atmosphere and surrounding environment to a certain extent.
At the same time, most of the catalysts used in waste paper and papermaking wastewater in the prior art are units, such as pyrite, Fe2O3, etc., and the catalytic efficiency of unit catalysts is limited. The limitations of catalysts are prone to agglomeration and deactivation

Abstract

The invention provides a preparation method of an iron peat supported iron-zinc-copper catalyst, and belongs to the technical field of environmental functional materials. The method comprises the following steps of: preparation of iron peat particles: washing off impurities on the surface of iron mud by using a water solvent, then performing granulating, and conducting drying at 110DEG C, then conducting roasting for 2-3h at 500-700DEG C in a nitrogen or inert gas atmosphere, and performing cooling to room temperature to obtain the iron peat particles; preparation of an iron peat supported iron-zinc-copper catalyst: putting the iron peat particles into a mixed solution consisting of an iron salt, a zinc salt and a copper salt, performing oscillating at room temperature for 18-24h, then taking out the iron peat particles, washing off unloaded active components on the surface by using a water solvent, performing drying at 110DEG C, and conducting calcining at 550DEG C for 2-4h in a nitrogen or inert gas atmosphere to obtain the iron peat supported iron-zinc-copper catalyst. According to the iron peat particles prepared by the method, sludge resource utilization is achieved, secondarypollution of iron mud is reduced, and the iron peat particles have good adsorption characteristics.

Description

technical field [0001] The invention belongs to the technical field of environmental functional materials, and in particular relates to an iron-peat-supported iron-zinc-copper catalyst, a preparation method and an application. Background technique [0002] With the development of industry, people's demand for paper continues to increase. In 2019, there were about 2,700 paper and cardboard manufacturers nationwide, and the total national pulp production was 72.07 million tons. Pulp is divided into wood pulp, non-wood pulp, and waste paper pulp. In 2019, waste paper pulp accounted for 74.25% of the total pulp and is the main source of pulp. The rapid development of the paper industry has brought some environmental problems at the same time. A large amount of papermaking wastewater will be generated in the pulping process, and a large amount of waste paper sludge will be generated in the wastewater treatment process. According to statistics, an average of 60-100 m3 of paper is ...
