Description
Technical field
The invention belongs to the biological organic complex fertilizer field, be specifically related to a kind of preparation method of phosphorous compoiste fertilizer.
Background technology
Solid white spirit waste lees is the main by product that liquor is produced, and also is the principal pollutant that liquor is produced.According to statistics, losing poor generation is 4 ~ 8 times of liquor output, and at present the whole nation needs poor the reaching more than 5,000 ten thousand tons of losing of handling.Therefore, the comprehensive utilization of vinasse has crucial meaning to development of resources and environment protection.On the one hand because the general raw materials such as Chinese sorghum, glutinous rice that adopt, lose and contain rich in protein, amino acid, VITAMINs and various trace elements etc. in poor, for the comprehensive utilization of solid white spirit waste lees provides good condition.Because special production technique is lost poor acidity height, be prone to corrupt going bad on the other hand, if untimely processing, must serious environment pollution.
Phosphate fertilizer is that Chinese agriculture is produced one of required nitrogen, phosphorus, potassium three big basic materials fertilizer; The main raw material of producing phosphate fertilizer is a Rock Phosphate (72Min BPL), and Guizhou Province's phosphate rock resource total amount is very abundant, about 2,700,000,000 t of proven reserve; Retained reserve 2,500,000,000 t are one of China three big phosphorus ore bases.But phosphorus ore will produce a large amount of chemical flotation tailings slags, wherein w (P after chemical flotation
2O
5)≤10%, w (MgO)>=15%.Such phosphorus mine tailing phosphorus content is low, belongs to the mining industry solid waste in the industrial solid castoff, and the soil pollution area that present China causes because of mine tailing reaches 1,000,000 mu, more than 1,000 ten thousand mu of indirect pollution land areas.
Therefore, the present invention combines solid white spirit waste lees with the phosphorus mine tailing, through microbial process; Prepare a kind of novel phosphorous compoiste fertilizer; Meet the needs that country greatly develops recycling economy, realize the comprehensive utilization of the two, for agriculture prodn provides favourable condition.
Summary of the invention
The objective of the invention is to pass through pretreated vinasse and mix, handle through functional microorganism again, prepare a kind of phosphorous compoiste fertilizer product with the phosphorus mine tailing.
The technical scheme that the present invention adopts: the preparation method of phosphorous compoiste fertilizer comprises specifically may further comprise the steps the preparation and the granulation packing of the pre-treatment of vinasse, phosphorous compoiste fertilizer:
(1) pre-treatment of vinasse: vinasse and water mix, and by volume weight ratio 2% ~ 6% is inoculated Aspergillus fumigatus seed culture fluid, raw material fermentation;
(2) preparation of phosphorous compoiste fertilizer: through 25 ~ 65 parts in pretreated vinasse; 35 ~ 60 parts of phosphorus mine tailings; 5 ~ 20 parts in water; More than one in weight ratio 1% ~ 6% inoculated aspergillus niger seed culture fluid, bacillus megaterium seed culture fluid, milk-acid bacteria seed nutrient solution, the white-rot fungi seed culture fluid by volume, mixing, raw material fermentation;
(3) with the above-mentioned compoiste fertilizer granulation that ferments, packing.
The preparation method of described a kind of phosphorous compoiste fertilizer, in the pre-treatment of vinasse, vinasse are 1:1 ~ 1:2 with the quality ratio.
The preparation method of described a kind of phosphorous compoiste fertilizer, in the pre-treatment of vinasse, ventilation is: cultivated 3 ~ 7 days down for 15 ~ 30%, 42 ~ 48 ℃.
The preparation method of described a kind of phosphorous compoiste fertilizer in the preparation of phosphorous compoiste fertilizer, cultivated 3 ~ 7 days down for 28 ~ 34 ℃.
The preparation method of described a kind of phosphorous compoiste fertilizer, said phosphorite tailings powder is the discarded tailing powder.
The preparation method of described a kind of phosphorous compoiste fertilizer, the concrete steps of granulation process are following:
Adopt granulating disc to carry out granulation, load weighted material is placed granulating disc, start tablets press, regulate tablets press rotating speed and disk tilt angle; After treating the abundant mixing of material, granulation 30min; Behind the tablets press out of service, granular compound fertilizer is taken out from granulating disc, be placed on drying in 70 ℃ of baking ovens, then through cooling, screening can obtain finished product just.
The beneficial effect that the present invention reaches:
(1) comprehensive utilization of waste and pollutent is turned waste into wealth
Solid white spirit waste lees is the main by product that liquor is produced, and also is the principal pollutant that liquor is produced; Phosphorus mine tailing phosphorus content is low, belongs to the mining industry solid waste in the industrial solid castoff.The present invention combines solid white spirit waste lees with the phosphorus mine tailing, through microbial process, prepare a kind of novel phosphorous compoiste fertilizer, meets the needs that country greatly develops recycling economy, realizes the comprehensive utilization of the two, for agriculture prodn provides favourable condition.
