Problems solved by technology

At present, the reuse of edible fungus residues is mainly used as ingredients for the reproduction of edible fungi, animal feed, and moldy residues can be used as fertilizers when they are not suitable for secondary cultivation materials and animal feed. However, these utilization methods also have high investment costs and are affected by the market. Large, causing secondary pollution to the environment and other problems, so it has not been well promoted

Abstract

The invention relates to a method for preparing a sewage treatment adsorbent, and particularly relates to a method for preparing a sewage treatment adsorbent by edible fungi residues. The method comprises the steps of with the edible fungi residues as raw materials, crushing the raw materials, carrying out microwave-assisted alkali process degradation, washing, formaldehyde modification, washing, and drying. The sewage treatment adsorbent prepared by adopting the method not only solves the problem of waste of a fungi residue resource, and also can be used for adsorbing and settling suspended particles, organic dye, heavy metal ions and the like in the earlier-stage processing of sewage, thereby realizing a function of recycling the edible fungi residues.

Description

technical field [0001] The invention relates to a method for an adsorbent for sewage treatment, in particular to a method for preparing an adsorbent for sewage treatment from edible fungus residues. Background technique [0002] The compost after the cultivation of edible fungi is called fungus residue or fungus chaff. The number of fungus residues produced in our country is at least 4 million tons every year. The traditional method to deal with these fungus residues is to discard or burn them. Combustion is an unreasonable use of biomass, because only about 10% of the heat energy can be obtained quickly, and random discarding is a waste of resources, and it also leads to the growth of mold and pests, which will cause environmental pollution, so it is reasonable The development and utilization of edible fungus residues can not only turn waste into wealth, but also reduce environmental pollution. At present, the reuse of edible fungus residues is mainly used as ingredients f...
