Description
Technical field
The present invention relates to biological organic water-soluble fertilizer preparation method technical field, be specially and utilize the production of papermaking-method reconstituted tobaccos waste liquid water-soluble
Fertile method.
Background technology
Papermaking-method reconstituted tobaccos also claims tobacco sheet, is that a kind of one made after modern extraction and separation technology improves in conjunction with traditional paper-making process technology for basic substance adopts with tobacco byproduct and dead meal is like smoke product.This type of tobacco material is except having a large amount of organic matter contained by general agriculture production resistates and micro-element nutrition salt, also be rich in abundant Threonine and tryptophane, after extraction concentration technique, this part nutritive substance is transferred to produce in extracting solution to return as fragrance matter and is added on tobacco sheet substrate.But can not accomplish to backfill completely in actual production, a part of extracting solution will enter follow-up water technology as production waste liquid.Therefore, on the one hand the extracting solution that produces of leaching process can not complete-reclaiming in reconstituted tobacco production process, cause the waste of resource; On the other hand, enter water technology as production waste liquid and cause BOD, COD of producing waste liquid all very high, treatment cost of waste liquor is higher, seriously constrains the Sustainable development of each reconstituted tobacco manufacturing enterprise.
Amino acid water-soluble fertilizer is a kind of new-type fertilizer containing amino acids material, is also a kind of multifunctional fertilizers.One or more amino acid can be contained; also can need to come arranging raw material for need of production or technology, conventional is Threonine, L-glutamic acid, glycine, phenylalanine, methionine(Met), aspartic acid, proline(Pro), Isoleucine, arginine, taurine, Gamma Amino Butyric Acid etc.Polyglutamic acid, poly-aspartic-acid etc. are class of amino acid polymkeric substance, and it is hydrolyzed in the solution or can be hydrolyzed to amino acid after Crop, has amino acid whose essential property and effect.Exist with the form of amino acid salts or free acid under standard state.Research shows, poly aspartic acid can strengthen the overall absorption of crop to nitrogen, phosphorus, potassium and medium trace element, improves utilization rate of fertilizer, growth promoting effects, increase yield, improves crop quality, promotes root growth, strengthens resistance and improvement soil.Amino acid Water soluble fertilizer is generally add the liquid or solid fertilizer that one or more amino acid starting materials or stoste makes.
Containing various element needed for production estimation and abundant Threonine and tryptophane in papermaking-method reconstituted tobaccos waste liquid, it is the good raw material of producing natural amino acid acid Water soluble fertilizer.The pollution that both can reduce environment is made full use of to it, the waste of resource can be reduced again, also can obtain the amino acid water-soluble fertilizer of high added value.Therefore study a kind of method utilizing papermaking-method reconstituted tobaccos waste liquid to produce natural amino acid Water soluble fertilizer, there is very positive meaning.
Summary of the invention
The object of the invention is to the characteristic for the various element contained in the problem that papermaking-method reconstituted tobaccos industrial enterprise production treatment cost of waste liquor is high at present and papermaking-method reconstituted tobaccos waste liquid needed for production estimation and abundant Threonine and tryptophane both at home and abroad, a kind of method utilizing reconstituted tobacco waste liquid to produce natural amino acid fertilizer is provided.
