Problems solved by technology

However, with the rapid development of the dye and printing and dyeing industries, a large amount of industrial wastewater containing dyes is discharged into the water environment every year. This type of wastewater has deep color, high content of organic pollutants, complex components, water quality changes, high biological toxicity, and is difficult to biodegrade. , the dye has strong anti-photolysis and anti-oxidation properties, and contains a variety of organic substances that are biologically toxic or cause "three causes" (carcinogenic, teratogenic, and mutagenic). It is difficult to treat sewage with conventional methods, which brings severely polluted

Description

[0001] technical field [0002] The invention belongs to the technical field of inorganic organic hybrid materials, and in particular relates to a relatively stable zinc metal organic framework material and a preparation method thereof. [0003] Background technique [0004] The continuous development of society promotes the development of the chemical industry, but industrial wastewater is also increasing in the process of development. Dye wastewater is one of the main harmful industrial wastewater. Dyes play a very important role in people's daily life, not only in textile, paper and other industries, but also in the food industry. Because of its existence, our life becomes colorful. However, with the rapid development of the dye and printing and dyeing industries, a large amount of industrial wastewater containing dyes is discharged into the water environment every year. This type of wastewater has deep color, high content of organic pollutants, complex components, w...
