Abstract
The present invention relates to a method for preparing a fertilizer, specifically to a method for preparing a semi-organic fertilizer by using a molasses ethanol waste liquid, and belongs to the technical field of chemical industry. The method comprises: adopting a molasses ethanol waste liquid concentrated solution as a raw material, adding a fused calcium-magnesium phosphate fertilizer and potassium chloride according to a ratio of 10:1, adding sulfuric acid, carrying out dehydration curing, then carrying out breaking, drying granulation, cooling and other processes to prepare a semi-finished product, and finally matching the semi-finished product and urea according to a ratio of 10:1 to prepare the semi-organic fertilizer. The semi-organic fertilizer can be adopted as a crop fertilizer, beneficial cycle is achieved, ethanol resource utilization is achieved, and the waste is changed into treasure.
Description
Technical field
The present invention relates to a kind of method for preparing chemical fertilizer, be specifically related to the method that a kind of molasses alcohol waste liquid prepares half fertilizer, belong to chemical technology field.
Background technology
At present, all set up the Alcohol Production workshop in large-scale sugar chemical synthesis, the alcohol slops colloid of discharge is many, color and luster is dark, and the pH value is 4.3～4.6, contains solid substance 12～15, total reducing sugar 2～3, ash content 4～5, COD 12～140,000 mg/l, BOD54～60,000 mg/l, these alcohol slopss are unprocessed, directly enter rivers, severe contamination water quality, destroyed the eubiosis of water system, environmental protection hidden danger is very large.By being shown in the alcohol slops, the alcohol slops analytical test contains a large amount of nutritive substances, the alcohol slops dry substance is organic more than 60%, wherein contain sugar, protein, VITAMIN, nitrogen, phosphorus, potassium etc., how alcohol slops is effectively used, making a silk purse out of a sow's ear, is a problem that needs to be resolved hurrily.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, provide a kind of molasses alcohol waste liquid to prepare the method for half fertilizer, the method utilizes the molasses alcohol concentrated liquor to be raw material, by allocating fused(calcium magnesium)phosphate, Repone K at 10: 1, add again the sulfuric acid dehydrating and curing, make work in-process through breaing up, dry the operations such as granulation, cooling again, at last work in-process are cooperated by 10: 1 with urea, make semi-organic fertilizer.Semi-organic fertilizer with fertile, is realized benign cycle as farm crop, does like this realization alcohol effluent resource, and accomplishing turns waste into wealth.
The present invention realizes with following technical scheme: a kind of molasses alcohol waste liquid prepares the method for half fertilizer, it is characterized in that: be with alcohol slops through the neutralization after, send into four-effect evaporator system and carry out evaporation concentration, the concentration of alcohol slops from 12～15Bx, bring up to 70Bx, as raw material for standby; Utilize the molasses alcohol concentrated liquor to be raw material, allocate fused(calcium magnesium)phosphate, Repone K into by 10: 1, add again the sulfuric acid dehydrating and curing, make work in-process through breaing up, dry the operations such as granulation, cooling again, at last work in-process are cooperated by 10: 1 with urea, make semi-organic fertilizer.
This preparation method's main technologic parameters is: (1) alcohol slops concentrated solution 65-75Bx, pH=6.5～7; (2) the 35-40 minute curing reaction time; (3) oven dry tablets press outlet air temperature is 115-125 ℃; (4) revolution cooler drop temperature≤45 ℃.
Advantage of the present invention is: this preparation method's technique is simple, the method utilizes the molasses alcohol concentrated liquor to be raw material, by allocating fused(calcium magnesium)phosphate, Repone K at 10: 1, add again the sulfuric acid dehydrating and curing, make work in-process through breaing up, dry the operations such as granulation, cooling again, at last work in-process are cooperated by 10: 1 with urea, make semi-organic fertilizer.Semi-organic fertilizer with fertile, is realized benign cycle as farm crop, does like this realization alcohol effluent resource, and accomplishing turns waste into wealth.
