Embodiment 1

[0023] An environmentally friendly recycling method for golden nanmu waste sawdust, specifically comprising the following steps:

[0024] (1) Sieve the waste wood chips of Phoebe nanmu to 30 meshes, then put them into a stirring mill and grind them into powder together with a ball milling medium, and set aside;

[0025] (2) Dissolve the compound enzyme which accounts for 3% of the total amount of the above powder by mixing lignin peroxidase and bacterial enzyme softener in equal mass ratio in warm water, mix it with the above powder and place it at 30°C Carry out ultrasonic enzymolysis for 3 hours in a special ultrasonic instrument to obtain enzymolyzed sawdust for subsequent use;

[0026] (3) Soak the enzymatically hydrolyzed sawdust in the plant extract, soak at 40°C for 3h, then heat to 70°C and boil for 1h, filter to obtain the filter residue, rinse the filter residue and put it in an oven at 40°C for drying Dried to 10% moisture, set aside;

[0027] Wherein, the plant e...

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. Contents of the invention [0003] The purpose of the present invention is to: aim at the above existing problems, to provide an environmentally friendly recovery met...
