Abstract
The present invention relates to a technology of making an organic fertilizer by using agricultural straw, more specifically to a technology of making an organic fertilizer by using papermaking waste liquid and agricultural straw, which solves the problem that the paper making waste liquid is difficult to treat in the prior art. The technology comprises the following procedures: mixing the paper making waste liquid with straw powder, heating the paper making waste liquid and the straw powder, and pressurizing and cooking the paper making waste liquid and the straw powder; neutralizing the slaked mixture by acid; adding yeast and enzymes to the neutralized mixture after biological fermentation, and drying the mixture, the yeast and the enzymes after phosphorization, ammoniation by adding ammonia to the materials and potassic alteration. The fertilizer changes traditional ideas that mineral substances are used as a carrier of effective components in making, so that the agricultural straw is used as the carrier; the fertilizer integrates the characteristics of organic fertilizers and inorganic fertilizers by adopting the processes, such as fermentation, the ammoniation, the phosphorization, etc., and organic matter and humus in the fertilizer can improve soil, prevent soil from being hardened, and enhance the progenitive activity of microbes in soil so as to enhance the aggregate structure of soil.
Description
Technical field
The present invention relates to a kind of agricultural crop straw that utilizes and make organic fertilizer technique, be specially a kind of papermaking wastewater and agricultural crop straw of utilizing and make fertilizer technology.
Background technology
At present, the method main purpose of the sewage disposal that produces after the papermaking is that the pollution substance in the water is separated with water, perhaps certain material that extracts wherein utilizes again, but because the sewage composition is extremely complicated, administer the investment enormous amount that needs, as everyone knows, some not possess the waste water of the paper mill of sewage treatment capacity discharging be the major reason that many rivers and soil are polluted; Particularly in vast Rural areas, because the cost of disposing of sewage is high and lack effective supervision, this phenomenon is more outstanding.Yet all can produce a large amount of agricultural crop straws every year in the Rural areas, handles the method for these stalks and generally abandon, or burn, and also is used as compost.Existing fertilizer mainly is three classes, and quick-acting fertilizer is as urea commonly used, carbon ammonia; Slow-release fertilizer mainly is the homemade fertilizers of some farmers'; Also having fertilizer indirectly, itself do not contain the required nutrition of crop, mainly is the potential of hydrogen by change soil, and physical and chemical index reaches the purpose that changes edatope, as bacterial manure, and lime, gypsum etc.More in the prior art relevant for the technology of directly utilizing agricultural crop straw making fertilizer, be generally crushed stalk, fermentation is mixed a certain proportion of auxiliary material again and is got final product then.
Summary of the invention
The present invention provides a kind of papermaking wastewater and agricultural crop straw of utilizing to make fertilizer technology in order to solve the problem that papermaking wastewater is difficult to handle in the prior art.
The present invention is realized that by following technical scheme a kind of papermaking wastewater and agricultural crop straw of utilizing made fertilizer technology, comprises the following steps:
1., heat after papermaking wastewater (claiming black liquid again) and straw powder are mixed, pressure cooking.900～1100 kilograms of papermaking wastewaters and 700 kilogram of 60 purpose straw powder are mixed, send in the rotary spherical digester and heat, make pressure reach 5-8 normal atmosphere, kept 4-6 hour.Purpose is the slaking straw powder.Straw powder also can replace with weeds.
2., the mixture after the slaking is neutralized with acid.Straw powder mixture after the slaking is added vitriol oil 4-10 kilogram, mixture is reached till the neutrality.
3., biological fermentation, the mixture after the neutralization is added yeast and enzyme, the mixture that is adjusted into after the neutrality is forwarded in the fermentation vat, add yeast powder by the amount of every cubic metre of 15-25 kilogram, and stalk lytic enzyme 1-2 kilogram.Mixing and stirring secondary fermentation 5-7 days.The stalk lytic enzyme is called cellulolytic enzyme again, as the biological straw zymophyte and the cellulolytic enzyme series product of the too rich youngster's biotechnology in Tangshan company limited production.
4., phosphatization, in above-mentioned material, add strong phosphoric acid 60-110 kilogram, and reaction 2-4 hour, this moment, pH value was 2-3.Phosphoric acid can quicken the decomposition of tangerine stalk and increase phosphorus element content, and can chemical reaction take place with metal in the tangerine stalk mud such as potassium sodium calcium etc., generates potassium primary phosphate, SODIUM PHOSPHATE, MONOBASIC, and calcium phosphate etc. react.
5., ammoniumization, in material, add ammoniacal liquor, in mixed reactant, add ammoniacal liquor 110-130 kilogram, airtight pressurization also keeps 5-8 normal atmosphere, regulating pH value at last is 7-8.The ammoniacal liquor phosphoric acid that neutralized, and improved nitrogen content.Airtight is in order to prevent ammonia volatilization.Adding and press air compressor machine, mainly is in order to quicken the synthetic of ammonia salt and prevent volatilization under cryogenic situation.
6., potassiumization, in material, add vitriolate of tartar 90-100 kilogram, the reaction times was controlled at 2-3 hour.Potassium is the essential element of crop growth, and it is exactly in order to improve the quality of fertilizer that this step adds sylvite.
Maximum characteristics of the present invention are exactly the waste water that papermaking produces to be handled with agricultural crop straw integrate, and have not only solved papermaking wastewater unrest environmental pollution caused by discharge problem, and have found outlet for the comprehensive utilization of agricultural crop straw.The product of making according to technology of the present invention is a Vandyke brown mucilage binding thing, and the ammonia flavor is arranged.Organic content comprises organic matter about 70%, soil ulmin, organic acid, polysaccharide, monose, materials such as Mierocrystalline cellulose.Contain the nitrogen about 10% in addition, about 10% phosphorus, about 5% potassium, and other mineral substance of 3%, it is rapid to use the back fertilizer efficiency, also can use in other fertile mixing, can play effect to each growth period of farm crop.It is the idea of effective constituent carrier with the mineral substance that this fertilizer has changed traditional on making, having formed with the agricultural crop straw is carrier, by fermentation, ammoniumization, technologies such as phosphatization are refining, combine the characteristics of fertilizer and inorganic fertilizer, the organism in the fertilizer, soil ulmin, can improve the soil, avoid soil compaction, increase the multiplication activity of microorganism in the soil, improved the crumb structure of soil.
