Abstract
The present invention relates to a comprehensive utilization and treatment method for iso electric-extrating mother liquor of glutamic acid, etc. in production of gourmet powder removing. It is characterized by including the following steps: making glutamic acid fermentation thallus flocculate; evaporating and concentrating purified liquor of thallus-removed mother liquor; using concentrated solution to make secondary extractin of glutamic acid and evaporating and concentrating mother liquor passed through secondary extraction to obtain solid fertilizer. The application of said invented technological process not only can bring pollution under permanent control, but also can recover thallus protein, residual glutamicacid, organic matter and nitrogen fertilizer from the waste mother liquor.
Description
The present invention relates in the glutamate production electricity such as L-glutamic acid and extract mother liquor comprehensive utilization improvement method.
It is the ripe mash of glutamic acid fermentation that electricity such as L-glutamic acid extract mother liquor (hereinafter to be referred as mother liquor).The remaining useless mash that the employing isoelectric point method extracts behind the L-glutamic acid belongs to high density organic acidity waste water, enters not only contaminate environment of rivers, and is the waste of resource.Usually adopt further fermentation to produce yeast or anaerobism one aerobic biology or the physical method of waiting handled for such waste water prior art, its result not only invests greatly, can not qualified discharge, and be the resource of preciousness to be treated as waste administer.
Purpose of the present invention is intended to avoid the deficiencies in the prior art and a kind of employing evaporation concentration mother liquor is provided, extracts residue in the mother liquor, the comprehensive utilization improvement method of water of productive use closed cycle and no waste discharge.
The object of the present invention is achieved like this:
Tropina in a, the recovery mother liquor, prior art adopts butterfly chip supercentrifuge to isolate thalline usually.This separation method not only invests height and separation efficiency is low, and the energy consumption height is difficult to apply.The present invention adopts chemistry or heating flocculation technique, makes trickle bacterium be condensed into floc sedimentation, thalline is removed clean with air supporting or filtering method then.In filtering removal thalline process, Mierocrystalline celluloses such as the waste bagasse of employing agricultural byproducts, sugarcane marrow, corn core, tangerine bar are processed into fine powder makes flocculating aids, and not only inexpensive strainability is good, and can guarantee the protein mass of filtered and recycled.
B, secondary extract L-glutamic acid again
L-glutamic acid residual in the mother liquor is usually at 1.5-2.0%, and the L-glutamic acid of 20-25% has emitted with mother liquor in the fermenting-ripening mash.Common employing adds acid, adds alkali, adds methods such as zinc salt or ion-exchange in the prior art, reclaims L-glutamic acid once more from mother liquor.These methods have not only increased the cost of pharmaceutical chemicals but also have increased the waste liquor amount.The present invention need not add any pharmaceutical chemicals.The iso-electric point mother liquor is a L-glutamic acid solubleness PH state hour.The present invention adopts the method for evaporation concentration, and moisture content in the mother liquor is removed, and when concentrated mother liquor was hypersaturated state, glutamic acid crystallization was separated out.Adopt this law secondary to extract L-glutamic acid again, its L-glutamic acid total yield is all higher than other method, and wastewater flow rate significantly reduces and reclaim organic for mother liquid evaporation is concentrated---and inorganic fertilizer provides condition.
C, extract mother liquor again and reclaim fertilizer
Extracting has the 40%-50% organic matter again in the mother liquor, all the other are that nitrogenous fertilizer (ammonium sulfate or ammonium chloride) secondary extracts in the mother liquor dry substance again up to 30-40%, and further evaporation concentration can make efficient organic-inorganic composite fertilizer again.
D, evaporation concentration phlegma are back to glutamate production, no waste discharge
The evaporation condensed water that produces during mother liquid evaporation concentrates is as clear as crystal, can be back to glutamate production, realizes the water of productive use closed cycle, the cleaner production no waste discharge.
Accompanying drawing is seen in technical process of the present invention.
The invention will be further described below in conjunction with embodiment:
Certain is produced the day discharging of 8000 tons of factories of monosodium glutamate per year and waits 250 tons of electric mother liquors, and dry solids content 10% in the mother liquor, residual L-glutamic acid 1.8% (L-glutamic acid 8.3% in the ripe mash), dry mycelium content 1.25%;
Adopt the technology of the present invention, be heated to 80 ℃, thalline flocculation, sedimentation, add sugarcane marrow flocculating aids in chamber filter press, filter filter cake, behind the filtration cakes torrefaction tropina.The recyclable 19kg of mother liquor per ton contains the protein fodder of crude protein 53%.
Except that adopting quadruple effect vacuum-evaporation, the mother liquor clear liquid behind the thalline is concentrated into 4-5 doubly.Cooling concentration liquid gets glutamic acid crystallization, the recyclable 15kg L-glutamic acid of mother liquor per ton, and the L-glutamic acid total yield reaches 95%, than the highest freezing iso-electric point of existing extracting glutamic acid rate-go out five percentage points from the friendship method is taller.
Secondary extracts mother liquid evaporation again and is concentrated into 75-80%, with making organic-inorganic composite fertilizer after liquefied ammonia neutralization, the curing.Mother liquor per ton can get 70kg organic-inorganic fertilizer.
The present invention compared with prior art has following advantage:
1, the present invention extracts mother liquor as resource with electricity such as glutamic acid, rather than discarded object. Whole processing procedure do not add unnecessary material can from mother liquor, reclaim thalline, glutamic acid and Organic-inorganic fertilizer. 2, the invention belongs to waste water evaporation and concentration treatment technology, is not simple Evaporation process, but reclaim around the center that is extracted as of residue of mother glutamic acid mycoprotein and The process of fertilizer. 3, the present invention adopts cheap agricultural byproducts discarded object to make filter aid, has solved Difficult problem in the separation process of mother liquor thalline. 4, the present invention does not produce new pollution discarded object, and is real Existing cleaner production.
