Abstract
The papermaking black liquor of soda pulp is mixed with coagulant aid, curing agent and flucculant through stirring to separate its organic matter, inorganic salt and other nutrient matters. The nutrient matters are dewatered and mixed with proper amount of sawdust, plant straw, cane sugar, bran, gypsum, lime or calcium carbonate, etc. to produce the edible fungi culturing medium. The present invention is simple, high in effect, and can utilize black liquor to avoid its environmental pollution.
Description
Technical field
The present invention relates to a kind of method of extracting black paper-making liquid of alkali pulping nutriment compounding edible fungus culturing base-material, belong to the regeneration class of slurrying alkali lye.
Background technology
Present pulping back liquor generally all is directly to enter rivers, cause serious environmental to pollute, simultaneously, organism such as the xylogen that contains in the black liquor, part Mierocrystalline cellulose, organic acid sodium salt, polyose and a large amount of carbon, hydrogen, sulphur, nitrogen, sodium element and various inorganic salts also enter rivers thereupon, both contaminate environment, cause organism and inorganics to run off again, can not regeneration; In fact, edible fungus culturing is needed just for the nutrient that organism and various inorganic salts contained such as contained xylogen, Mierocrystalline cellulose, polyose in the black liquor, and domestic technique is not mature enough in this regard at present, can not really develop black liquor and administer black liquor pollution.
Summary of the invention
The object of the present invention is to provide a kind of extraction black liquor nutriment material, the method for compounding edible fungus culturing base-material is carried out Edible Fungi thereby make full use of black liquor nutriment material, avoids black liquor pollution simultaneously.Particular content of the present invention is: the boiling slurry carries out the slurries separation after rotary spherical digester is discharged, the alkalescence black liquor is behind fiber recovery, preliminary sedimentation, utilize volume pump that black liquor is promoted in the black liquor dosing reaction tank, successively drop into coagulant aids, solidifying agent and flocculation agent, and stir, organism in the black liquor, the curing of inorganic salts nutriment material are separated out, and these nutriment materials are after processed, and its water ratio is 60～70%; The compound method of edible fungus culturing base-material is wood chip or the plant straw bits that the requirement of cultivation base-material are equipped with its quality 25～35% in water ratio is 60～70% nutriment material according to different edible mushroomss, selectivity is equipped with suitable amount of sucrose, wheat skin, gypsum, nitrogenous substances, lime or lime carbonate simultaneously, regulate pH value to prescribed value, the cultivation base-material of edible mushrooms of different varieties; Described coagulant aids is wilkinite or gelatine, and described solidifying agent is a dilute sulphuric acid, and described flocculation agent is sodium polyacrylate or polyacrylamide or acrylamide; Described coagulant aids is the aqueous solution of 1～20% concentration, and described solidifying agent is the aqueous solution of 5～30% concentration, and described flocculation agent is the aqueous solution of 0.1～1% concentration.In the leaching process of pulping back liquor nutriment, the mass ratio of black liquor and the coagulant aids aqueous solution, aqueous solution of curing agent and flocculant aqueous solution is respectively 1: 0.01～0.1,1: 0.05～0.3,1: 0.01～0.2.
Extract nutriment material in the black liquor, press mass ratio and drop into coagulant aids, need to stir through 2～5 minutes, drop into solidifying agent again, stirred 3～10 minutes, drop into flocculation agent at last, stirred 3～10 minutes, black liquor promptly solidifies nutriment materials such as separating out xylogen, Mierocrystalline cellulose, gets final product through processed.
Key of the present invention is that the coagulant aids that drops into can promote when extracting black liquor nutriment that the nutriment material solidifies, gathers in the black liquor, can also adjust the trophic structure of base-material when separating out nutriment material, compounding edible fungus culturing base-material; The solidifying agent that drops into, flocculation agent also must keep the useful matter in the black liquor not to be destroyed except can successful curing separating out in the black liquor the nutriment material.These technical characterstics have determined the above medicament of necessary use or similar with it medicament.
The present invention compared with prior art, it is not the simple black liquor treatment that carries out, and is worth but develop it at the composition of black liquor, reaches the effect of administering black liquor pollution simultaneously.In sum, technology of the present invention is simple, processing ease, and running cost is low, and effect is remarkable, both can develop value, the creation economic benefit of black liquor, has effected a radical cure black liquor pollution again, turns waste into wealth, and is applicable to the alkaline process papermaking enterprise of various scales.
