Silkwood waste dust environment-friendly recycling method

Abstract

The invention relates to the technical field of waste wood dust recovery, in particular to a silkwood waste dust environment-friendly recycling method. The method comprises the steps of (1) crushing and grinding wood dust; (20 conducting enzymolysis on the wood dust through a compound enzyme formed by mixing lignin peroxidase and a lysozyme softening agent; (3) soaking the zymolytic wood dust intoa plant extract, heating, boiling and filtering the wood dust to obtain filter residues, and rinsing, cleaning and drying the filter residues for standby application, wherein the plant extract is mainly prepared from the raw materials such as peach leaves, onions, oleander leaves, lemon peels, tung oil, radix sanguisorbae, radix rubiae, puffball and lemon essential oil; (4) bleaching the wood dust; (5) conducting jordaning, latency elimination, washing, screening and pulping to obtain wood dust serous fluid for paper making. The wood dust serous fluid has special fragrance and has the functions of sterilizing and avoiding ants and cockroaches, so that made-up paper sheets have the special fragrance and can be prevented from being gnawed by the cockroaches and the ants, and the service life of the paper sheets is effectively prolonged. Accordingly, the environment-friendly recycling use value of the wood dust is effectively increased.

Description

technical field

[0001] The invention relates to the technical field of recycling waste sawdust, in particular to an environmentally friendly recycling method for waste golden nanmu sawdust. Background technique

[0002] Jinsinnan is a kind of nanmu with golden threads and satin-like luster in some materials. The wood has aroma, straight texture and fine structure, and is not easy to deform and crack. It is an excellent wood for construction and high-end furniture. When golden nanmu is processed into various special-shaped furniture, sawdust will be produced, and most of the sawdust is used as firewood for direct combustion, which cannot be recycled well, and direct combustion will produce a large amount of carbon monoxide and carbon dioxide, which will pollute the environment , very environmentally friendly.
