Description
Technical field
The invention belongs to trade waste and recycle field, relate to a kind of high comprehensive reutilization method oozing fermented waste fluid and mud.
Background technology
Molasses are syrup remaining in sugar refining technology process, and molasses fermented process reality is also the further biochemical degradation of organism, conversion process.Domestic when taking molasses as raw material production alcohol, approximately often produce 1t alcohol consumption 4t molasses, about discharge the waste liquid of 14t, the pH value of waste liquid is generally 3.0-3.5, mainly containing carbohydrate (polyose) and alcohols.The pH value of molasses yeast wastewater is generally 4.0-5.0, main containing biodegradable larger molecular organicses such as remaining sugar, nutritive salt, partial yeast cell and pectin substances.Except containing except a small amount of L-glutamic acid in molasses msg mother liquor, also there is thalline, residual sugar, high ammonium state nitrogen, pigment, colloidalmaterial and other fermentation byproduct.Current molasses fermented liquid organic waste water adopts agricultural reutilization technological line, solves waste water pollution problem, and promotes the Sustainable development of waste ecological circulation and industrial or agricultural.Papermaking and molasses fermented industrial effluent contain a large amount of organic matters and various nutrient elements, and evaluate from Plant Nutrition angle, these two kinds of waste liquids all belong to Organic Fertilizer Resources, but can not directly use in a large number as organic fertilizer.If amount of application too much, may cause plant-growth to be suppressed, injure, even death.Its major cause is molasses fermented waste liquid is high concentrated organic wastewater, and water-soluble C content is high, and biological activity is strong, containing more low molecule organic matter, as residual sugar, organic acid etc., particularly sugar easily ferment in soil, generate heat, crop of burning, and make the further acidifying of soil.Therefore molasses fermented trade waste (waste liquid and mud) agricultural before, generally all need to carry out desugar and humify further, stabilization, the i.e. harmless treatment of molasses fermented waste liquid.
Fermentation produce waste also comprise lime-ash and mud, especially cassava grain stillage mud through fermentation after containing have an appointment about 30% moisture, such material can not be pulverized and can not carry out granulation, needs further processing treatment.And a large amount of high concentrated organic wastewater is produced in cassava alcohol production process, these waste water produce biogas through anaerobically fermenting, are settled out a large amount of mud, and the efficient economy recovery and utilization technology of mud has become a problem in the urgent need to address.
Because organism most of in high concentrated organic waste liquid is not fully degraded, to be spray dried to after dry powder the easily moisture absorption, rotten and viscosity is large, to limit recycling.For the stabilization treatment of sugary organic liquid, except the anaerobe digestion degraded of routine, over the past two years, there have been developed sugar and yeast separation recovery technology, carrier adsorption solid aerobic compost new technology, basic material (lime) stabilization technology etc. that dewaters and be particularly suitable for the quick humify of organic liquid waste and batch production utilizes.
Utilize sulfuric acid stabilization waste liquid, its principle is that sulfuric acid and gas chromatography react, and comprises starch and degraded and Transglycosylation occur, generate oligose; Hemicellulose Polysaccharide class is hydrolyzed; Proteolysis becomes polypeptide, amino acid; Two pools and monose dehydration generate aldehyde material, and under concentrated acid and heating condition, polysaccharide stabilizes process is the dynamic process that organism is progressively degraded, transformed, and degree of humification and acid concentration, temperature, pressure, time are relevant., mainly there is organic alkaline hydrolysis, dehydration and partial condensates and react, though cost is low, easily denitrogenation phenomenon occurs, cause nutrient loss and stink greatly, and the acid treatment of liquid carbonized strength ratio is weak in basic material stabilization treatment organic liquid waste.
Although at present acid or alkalescence all can play humification, all there is meta-acid or meta-alkali after humify in the two, all separately will add alkali or another acid adding neutralizes, and just can make the product conforming with composite fertilizer's quality standard.So the present invention proposes the method that both employings combine, molasses fermented waste liquid concentrated solution is carried out acid, alkali humify respectively, then the fermented waste fluid after the two mitigation neutralization makes humify can be used for preparing multiple organic/inorganic mixing composite fertilizer, this organic/inorganic mixing composite fertilizer utilizes Modern microbiological technology, inoculation biological bacteria, through multistage fermentation culture, just efficient compound microbial culture starter can be produced; The lime-ash, mud etc. of adding generation in alcohol slops production, as matrix, develop fixing high-performance bio bacterial manure.
Summary of the invention
The object of the invention is to for waste molasses fermented in prior art not exclusively innoxious in for fertiliser production, humify acidifying or alkalinization single, cause humify poor effect, humify is incomplete, containing in molasses fermented waste liquid Fertilizer application process, secondary pollution is caused to soil, fertilizer for the growth etc. of crop without effect, providing one utilizes fermented waste fluid to prepare organic/inorganic mixed active composite fertilizer method, the method proposes the method adopting both acidifying or alkalization treating processes to combine, molasses fermented waste liquid concentrated solution is carried out acid respectively, alkali humify, then the fermented waste fluid after the two mitigation neutralization makes humify can be used for preparing multiple organic/inorganic mixing composite fertilizer, this organic/inorganic mixing composite fertilizer utilizes Modern microbiological technology, inoculation biological bacteria, through multistage fermentation culture, just can produce efficient compound microbial culture starter, the lime-ash, mud etc. of adding generation in alcohol slops production, as matrix, develop fixing high-performance bio bacterial manure.
