Problems solved by technology

Except some of these waste fungus chaff are used as livestock and poultry feed, organic fertilizer, flower soil, most of them are discarded or incinerated according to traditional treatment methods, which not only causes waste of resources, but also leads to the breeding of mold and pests, harmful spores and pests in the air. The increase in the number will cause environmental pollution

Abstract

The invention discloses a method for preparing activated carbon from waste mushroom residue. The method is realized by the following ways: removing outer packaging bag of waste mushroom residue, grinding the waste mushroom residue, adding AlCl3, FeCl3 and water, uniformly mixing, slowly adding hydrogen peroxide, and drying after reaction; adding a waste mushroom residue mixture to a high pressure reactor, charring and activating through ultrasonic wave heating, filling SO3 steam, and further carrying out heating and activating; after cooling, washing activated carbon through strong brine and washing materials through de-ionized water until filtrate is nearly neutral; and finally, drying a sample in a drying oven to constant weight. The activated carbon disclosed by the invention is prepared from waste mushroom residue, so that the method not only reduces cost of preparing the activated carbon but also is of great significance in environmental protection.

Description

technical field [0001] The invention relates to the technical field of preparing activated carbon, in particular to a method for preparing activated carbon by using waste fungus chaff. Background technique [0002] The biggest characteristic of activated carbon different from charcoal, coke and other carbon products is that it has a very high adsorption capacity. Activated carbon is a porous carbon-containing substance with a long history of development. As a carbonaceous material with well-developed pores, activated carbon has been used in various sectors of industry and national economy, as well as in environmental protection and all aspects of human life, as well as in space navigation, marine operations and cutting-edge science. [0003] Carbonaceous substances can be used as raw materials for the preparation of shaped granular activated carbon, which are mainly divided into two categories: coal raw materials and woody raw materials. Coal raw materials mainly include an...
