Abstract
The present invention discloses a method for manufacturing organic compound fertilizer by fermented waste molasses liquid, particularly a method for manufacturing organic compound fertilizer by fermented waste molasses liquid with high concentration, which belongs to the technical field of treating environmental pollution. The fermented waste molasses liquid is evaporated and concentrated, and is added to 100% concentration of industrial acid of which the weight accounts for 2% to 10% of that of solid solution substances in concentrated solution to be treated by chemical digestion at a constant temperature for more than 10 hours; then, the content of components, such as N, P, K, etc., is regulated, and the fermented waste molasses liquid is added to skeletal materials of which the weight accounts for 20% to 40% of that of the solid solution substances in the waste liquid; finally, the fertilizer is manufactured after granulation and desiccation.
Description
The present invention relates to a kind of organic composite fertilizer and be made into method, especially molasses fermented waste liquid is made the method for SOLID ORGANIC compound manure.
At present, the method of handling both at home and abroad the molasses fermented waste liquid of discharging in sugar refinery has following several: 1, directly molasses fermented waste liquid is executed and irritated the farmland, because molasses fermented waste liquid contains abundant organic matter and inorganic elements N, P, K etc., can be used as agriculture fertilizer, Zhujiang River sugar refinery, China Guangdong Province, sugar refinery, Guangfeng, Guangdong Province and Aug. 1st sugar refinery, Hainan Province all are molasses alcohol waste liquid directly to be irritated execute the farmland, but applying unit needs facilities such as storage pool, transport pipe, force (forcing) pump, limited by place, auxiliary facility, China overwhelming majority sugar refinery is difficult to promote.2, some sugar refinery is mixed and made into organic fertilizer with filter mud and bagasse coal ash and waste liquid, and evenly heap fermentation with inorganic composite fertilizer and make the organic composite fertilizer use, can bulk shipment, facility is simple, but owing to be simply to be made into technology, do not have concentrating, assimilating, available nutrient is not high, unsuitable prolonged preservation, the unit surface rate of fertilizer application is big, and every mu can reach 2000 kilograms.3, the later stage seventies, Japan consonance fermentation industry stock company concentrates the molasses alcohol fermentation waste liquid evaporation, add then concentrated solution weight 30%, the sulfuric acid of concentration 98%, digested 10 hours down at 110 ℃, mix to make organic composite fertilizer with inorganic fertilizer then, owing to allocate reasonable fertilizer nutrient into, made is high-efficiency organic mixed fertilizer, but because adopt account for concentrated solution weight 30%, the sulfuric acid digestion of concentration 98%, in manufacturing processed, need too much SO
4 -2Remove, producing has pollution, soil is caused the sulfur-containing waste water that hardens environment, need further to handle, but the cost for wastewater treatment height, complex treatment process, production cost is inevitable high, is difficult to industrialization promotion and uses.
The object of the invention is to provide a kind of processing molasses fermented waste liquid, with its be made into organic composite fertilizer low acid digestion, be beneficial to the manufacturing process of environment protection, in the hope of making high density, organic composite fertilizer that social benefit is good.
The present invention is achieved in that 1) the molasses fermented waste liquid of being discharged at the bottom of the tower with molasses alcohol distilled tower earlier delivers to the solid, liquid separator, the lime-ash of removing in the waste liquid to be mingled with.2) will remove and be mingled with cindery waste liquid and send into multiple-effect evaporator and carry out evaporation concentration, making this waste liquid be concentrated into soluble solids concentration is 70%-80%.3) be that to send into temperature be in 100 ℃ the constant temperature digestion device for the waste liquid of 70%-80% with soluble solids concentration, and adding accounts for the contained soluble solids weight of waste liquid 2%-10%'s simultaneously, by concentration is 100% commercial acid (sulfuric acid, hydrochloric acid, nitric acid or phosphoric acid all can), after mixing, carry out the constant temperature chemical digestion more than 10 hours, the organic substance major part of waste liquid is converted into humate.4) Digestive system cooling back that will be above-mentioned is neutralized to PH=6-7 with alkaline matters such as ammonia or lime, and the content of its concentration of sampling analysis and N, P, K.5) adjust the content of compositions such as N, P in the solution, K, make their content reach the requirement of product specification.6) add again account for the contained soluble solids weight of waste liquid 20%-40%, exsiccant, granularity be above normal superphosphate powder or rock phosphate powder or aggregates such as double superhosphate powder or sugarcane marrow of 20 orders, makes slurry after mechanical stirring.7) slurry is delivered to tablets press granulation and being dried, made product water content＜5%.
Technology of the present invention is simple, reduce greatly digestion with the acid amount, acid consumption of the present invention only be the digestion of Japanese consonance company with acid measure 1/10, outside the reduction decapacitation of acid consumption reduces production costs, the content of sulfate radical helps using the tolerance of soil to fertilizer in can also corresponding minimizing fertilizer.
