Problems solved by technology

[0003] At present, the methods of dealing with these fungal residues include discarding, incinerating, and processing them into feed or fertilizer. Incineration can only quickly obtain about 10% of the energy, which is an unreasonable benefit to biomass; fungal residues are rich in protein and other Random discarding of nutrients is a waste of resources, and it is also easy to cause the growth of mold and pests, causing environmental pollution; fungal residues are safe to use as feed, but their effects have not been fully recognized and accepted by consumers, so There are certain restrictions in the market; it takes a long time for the fungus residue to be used for composting, and the content of nutrient elements is uneven after the end of individual composting

Abstract

The invention discloses a wastewater treatment agent prepared from edible mushroom residue and a preparation method of same. The wastewater treatment agent includes: the edible mushroom residue, compound enzyme, fermenting bacteria, water soluble starch, ammonium persulfate, ethyl carboxylate, ethyl p-hydroxybenzoate, Fe<3+> salt and Fe<2+> salt. The method particularly includes: 1) sterilizing and enzymolyzing the edible mushroom residue; 2) fermenting the enzymolyzed material; 3) puffing the fermented material; 4) adding water to the water soluble starch for gelatinization and adding the ammonium persulfate and the puffed edible mushroom residue, heating the mixture to carry out a reaction, regulating pH value, adding the ethyl carboxylate and ethyl p-hydroxybenzoate, and heating the mixture to continuously carry out a reaction; 5) moving the product into a reaction kettle, feeding nitrogen gas, and dropwise adding a mixed solution of the Fe<3+> salt and Fe<2+> salt to carry out a reaction; 6) cooling the product to room temperature, and washing, drying and crushing the product. The wastewater treatment agent is environment-friendly and high-effective and has good removal effecton heavy metals in the wastewater.

Description

technical field [0001] The invention belongs to the technical field of mushroom residue reuse, and in particular relates to a sewage treatment agent prepared by using edible mushroom residue and a preparation method thereof. Background technique [0002] my country is a big country in the production of edible fungi. In recent years, with the development of edible fungi production, the output of edible fungus residues in the country is huge. For a large amount of edible fungus waste, if it is not handled properly, it will pollute the environment, not only waste resources, but also hinder the smooth development of the edible fungi industry. Therefore, how to effectively utilize edible fungus slag in environmental protection becomes an increasingly serious problem. [0003] At present, the methods of dealing with these fungal residues include discarding, incinerating, and processing them into feed or fertilizer. Incineration can only quickly obtain about 10% of the energy, whi...
