Description
Technical field
The invention belongs to trade waste and recycle field, relate to a kind of high comprehensive reutilization method that oozes fermented waste fluid and mud.
Background technology
Molasses are syrup remaining in sugar refining technology process, and molasses fermented processing reality is also the further biochemical degradation of organism, conversion process.Domestic during taking molasses as raw material production alcohol, about every production 1t alcohol consumption 4t molasses, approximately discharge the waste liquid of 14t, and the pH value of waste liquid is generally 3.0-3.5, mainly contains carbohydrate (polyose) and alcohols.The pH value of molasses yeast wastewater is generally 4.0-5.0, mainly containing biodegradable larger molecular organicses such as remaining sugar, nutritive salt, part yeast cell and pectin substances.In molasses msg mother liquor, except containing a small amount of L-glutamic acid, 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 resource technology route, 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, evaluate from Plant Nutrition angle, and 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 is too much, may cause plant-growth be suppressed, injure, even dead.Its major cause is that molasses fermented waste liquid is high concentrated organic wastewater, and water-soluble C content is high, and biological activity is strong, contain more low molecule organic matter, as residual sugar, organic acid etc., the particularly sugar crop of easily fermenting in soil, generate heat, burn, 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 further humify, stabilization, the i.e. harmless treatment of molasses fermented waste liquid.
The waste that fermentation produces also comprises lime-ash and mud, and especially cassava grain stillage mud is containing the moisture of 30% left and right of having an appointment after fermentation, and such material can not be pulverized and can not carry out granulation, needs further processing treatment.And in cassava alcohol production process, produce a large amount of high concentrated organic wastewaters, 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.
Due to not fully degraded of most of organism in high concentrated organic waste liquid, be spray dried to after dry powder easily the moisture absorption, rotten and viscosity is large, limited recycling.For the stabilization treatment of sugary organic liquid, except conventional anaerobe digestion degraded, over the past two years, sugar and yeast separation recovery technology, carrier adsorption solid aerobic compost new technology, basic material (lime) dehydration stabilization technology etc. have also been developed and have been particularly suitable for quick humify and the batch production utilization of organic liquid waste.
Utilize sulfuric acid stabilization waste liquid, its principle is that sulfuric acid and gas chromatography react, and comprises that degraded and Transglycosylation occur starch, generate oligose; The hydrolysis of Hemicellulose Polysaccharide class; Proteolysis becomes polypeptide, amino acid; The dehydration of two pools and monose generates aldehyde material, and under concentrated acid and heating condition, polysaccharide stabilizes processing 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 part condensation reaction in basic material stabilization treatment organic liquid waste, though cost is low, denitrogenation phenomenon easily occurs, and causes nutrient loss and stink large, and the acid treatment of liquid phase charing strength ratio want a little less than.
Although at present acidity or alkalescence all can play humification, all there is meta-acid or meta-alkali after humify in the two, all will separately add alkali or another acid adding neutralizes, and just can make the product that conforms with composite fertilizer's quality standard.So the present invention proposes to adopt the method for the two combination, molasses fermented waste liquid concentrated solution is carried out respectively to acid, alkali humify, then the two relaxes neutralization and makes fermented waste fluid after humify can be used for preparing multiple organic/inorganic to mix composite fertilizer, this organic/inorganic mixes composite fertilizer and utilizes modern microbial technique, inoculation biological bacteria, through multistage fermentation culture, just can produce efficient compound microbial culture starter; Add the lime-ash, the mud etc. that in alcohol slops production, produce as matrix, develop fixing high-performance bio bacterial manure.
Summary of the invention
The object of the invention is to for molasses fermented waste in prior art innoxious not exclusively for fertiliser production, humify acidifying or alkalization process are single, cause humify poor effect, humify is incomplete, contain in molasses fermented waste liquid Fertilizer application process soil is caused to secondary pollution, fertilizer for growth of crop etc. without effect, provide one to utilize fermented waste fluid to prepare organic/inorganic mixed active composite fertilizer method, the method proposes to adopt the method for acidifying or the two treating processes combination of alkalizing, molasses fermented waste liquid concentrated solution is carried out respectively to acid, alkali humify, then the two relaxes neutralization and makes fermented waste fluid after humify can be used for preparing multiple organic/inorganic to mix composite fertilizer, this organic/inorganic mixes composite fertilizer and utilizes modern microbial technique, inoculation biological bacteria, through multistage fermentation culture, just can produce efficient compound microbial culture starter, add the lime-ash, the mud etc. that in alcohol slops production, produce as matrix, develop fixing high-performance bio bacterial manure.
