Embodiment 1
[0025] In this embodiment, a wool activated carbon-loaded adsorbent includes wool activated carbon and iron oxide, and the activated carbon body is loaded with iron oxide, wherein the wool activated carbon is made of wool through pre-carbonization and carbonization; the load iron oxide is loaded on wool The iron nitrate in the activated carbon body is calcined at high temperature.
[0026] Specifically in this embodiment, this embodiment uses wool with a length of about 10mm as the raw material. First, the waste wool of about 10mm is placed in a high-temperature tube furnace. Under the protection of nitrogen, the temperature rises by 10°C per minute to 240. ℃, and pre-carbonized at high temperature for 2 hours under the protection of nitrogen, and then lowered the temperature to room temperature under the protection of nitrogen. Mix the high-temperature pre-carbonized wool with potassium carbonate at a ratio of 4:4, put it into a high-temperature tube furnace again, and raise ...

Abstract
The invention relates to a preparation method of a wool activated carbon-loaded adsorbent, and belongs to the technical field of solid adsorbent compositions used for preparation, regeneration or reactivation. Using wool as the body, the wool is pre-carbonized-activated-re-carbonized to form wool activated carbon. After the wool activated carbon is adsorbed with iron nitrate, it is calcined to form a wool activated carbon-loaded adsorbent with iron oxide carrier. In this application, wool activated carbon is used as the base material to load iron oxide onto the activated carbon substrate through suitable preparation means to prepare a new type of adsorption to remove harmful substances in dyeing and finishing wastewater, which is easy to realize. The adsorption rate of this loaded adsorbent to simulated dyeing and finishing wastewater reaches 99 More than %, the effect is obvious, and the preparation process is simple and easy.
Description
technical field [0001] The invention relates to a preparation method of a wool activated carbon-loaded adsorbent, and belongs to the technical field of solid adsorbent compositions used for preparation, regeneration or reactivation. Background technique [0002] Dyeing and finishing wastewater is a liquid containing complex components such as dyes, sizing agents, additives, organics, acids and bases, fiber impurities, and inorganic salts. If the wastewater is discharged directly without treatment, it will cause serious pollution to the environment, especially in recent years. The printing and dyeing industry needs dyes to develop in the direction of anti-oxidation, anti-photolysis, and anti-biodegradation, which further increases the difficulty of printing and dyeing wastewater treatment; at the same time, most textiles are non-degradable substances. With the formation of a large amount of textile waste, it will affect the environment Pollution and increased costs for its us...
