Problems solved by technology

Due to the complex structure of dyes, the production process is often accompanied by reactions such as nitrification, oxidation, and diazotization, resulting in high organic content, deep color, and complex components in dye wastewater. At the same time, the renewal speed of dye products is fast, making dye wastewater treatment more difficult. Big

Abstract

The invention discloses an effective treatment method for methyl orange dye wastewater. The effective treatment method specifically comprises the following steps: firstly, by taking an aluminum foil as a substrate, preparing a honeycomb-shaped zinc oxide nano wall array, and plating the surface of the array with a layer of silver nanoparticles so as to obtain a catalyst; secondly, by taking 2-hydroxypropyl trimethyl ammonium chloride chitosan modified activated carbon as an adsorbent, putting the adsorbent into methyl orange dye wastewater firstly when the dye wastewater is treated, performing stirring adsorption for 10 hours at a pH value of 10.5 at the room temperature, filtering, and collecting filtrate; and putting the prepared catalyst into the collected filtrate, adjusting the pH value to 6, performing stirring treatment for 1-3 hours under a light shielded condition, performing stirring treatment for 20-60 minutes with visible light, filtering after the treatment is completed, and recycling the catalyst. By adopting the effective treatment method, dye molecules in wastewater can be effectively removed, and the treatment cost is lowered.

Description

Technical field: [0001] The invention relates to the field of dye wastewater treatment, in particular to an effective treatment method for methyl orange dye wastewater. Background technique: [0002] With the continuous development of the textile printing and dyeing industry, more and more dye wastewater is produced, which seriously endangers the ecological environment. Due to the complex structure of dyes, the production process is often accompanied by reactions such as nitrification, oxidation, and diazotization, resulting in high organic content, deep color, and complex components in dye wastewater. At the same time, the renewal speed of dye products is fast, making dye wastewater treatment more difficult. Big. The treatment methods of dye wastewater mainly include physical method, chemical method and biological method, among which chemical method is the most widely used. Photocatalytic degradation has become a commonly used treatment method in chemical methods because ...
