Abstract
The invention discloses a non-mineral source humic acid water-soluble liquid fertilizer. A formula is as follows: 28-40% of biogas residue mud, 15-25% of urea, 6-12% of phosphoric acid, 7-15% of potassium hydroxide, and the balance of a supernate of biogas wastewater. A preparation method of the water-soluble fertilizer comprises the steps of conducting dry and wet separation on fecal wastewater, conducting anaerobic fermentation on obtained liquid, generating the biogas wastewater, filtering, obtaining the supernate and the biogas residue mud of the biogas wastewater, adding urea and phosphoric acid to the supernate of the biogas wastewater according to the formula, stirring to allow urea and phosphoric acid to have chelation reaction, then adding potassium hydroxide, adding the biogas residue mud after sufficient reaction, uniformly stirring, and obtaining the water-soluble fertilizer. The water-soluble fertilizer obtains humic acid by utilizing microbial fermentation; humic acid has a higher function of adjusting crop growth; the supernate of the biogas wastewater is a very good liquid fertilizer; the preparation method of the water-soluble fertilizer by taking the supernate as a raw material is energy-saving and environment-friendly; and the treatment cost of the fecal wastewater is lowered.
Description
Technical field
The invention belongs to the technical field of fertilizer and preparation thereof, particularly a kind of non-mineral source humic acid water-soluble liquid fertilizer and preparation method thereof.
Background technology
Humic acid fertilizer is a kind ofly can promote crop growthing development, improves farm crop resistance and quality thereof, the multifunctional fertilizers of increasing both production and income; In addition, be raw material with the humic acids, can derive other fertilizer that much contain humic acids.
The existing fertilizer that contains humic acids is carried out according to People's Republic of China's industry standard (NY1106-2010), and its greatest problem is that the humic acids source also only limits to natural mineral source humic acids, is to extract from the peat composed of rotten mosses, peat, brown coal or weathered coal and get.No matter be above-mentioned which kind of humic acids source, all be exploitation mineral source material, obtains humic acids through extraction, be that cost brings to sacrifice natural ecological environment all, and these resources all are limited, thereby its prospect also is limited, and its development is unsustainable.Country was since 2008, and the outlet of restriction humic acids is the decision made from regard to being based on the humic acids Mineral resources of protecting China's preciousness.Now become big source of pollution and contain excrement sewage, traditional treatment process energy consumption height, of poor benefits, and secondary pollution is arranged.
Summary of the invention
The object of the present invention is to provide a kind ofly contain that non-mineral source humic acids and preparation method are simple, the humic acid water-soluble liquid fertilizer of energy-conserving and environment-protective and preparation method thereof.
For achieving the above object, technical scheme provided by the invention is: a kind of non-mineral source humic acid water-soluble liquid fertilizer, and it is as follows to fill a prescription: natural pond slag mud 28 ~ 40%, urea 15 ~ 25%, phosphoric acid 6 ~ 12%, potassium hydroxide 7 ~ 15%, all the other are the supernatant liquor of biogas waste water.
Preferably, optimization formula is as follows: natural pond slag mud 33%, urea 21.7%, phosphatase 11 1.8%, potassium hydroxide 7.1%, the supernatant liquor 26.4% of biogas waste water.
The preparation method of non-mineral of the present invention source humic acid water-soluble liquid fertilizer is: (1) will contain excrement sewage and do wet the separation, the liquid that obtains is anaerobically fermenting in the biogas jar, produce biogas and biogas waste water, the biogas waste water filtering is made solid-liquid separation, and obtaining the supernatant liquor of biogas waste water and the non-mineral source humic acids basic content of giving money as a gift is 10% ~ 30% natural pond slag mud; (2) by described prescription, urea, phosphoric acid are joined in the supernatant liquor of biogas waste water of step (1) preparation, stir, make urea, phosphoric acid generation chelatropic reaction, add potassium hydroxide again, stir, fully after the reaction, the non-mineral source humic acids that adds step (1) the preparation basic content of giving money as a gift is 10% ~ 30% natural pond slag mud, fully mixes, and obtains containing the water soluble liq fertilizer of humic acids after stirring.
A technical scheme in the technique scheme has following advantage or beneficial effect: what this invention was different from the past utilizes the mineral source humic acids as the method and the path that produce humic acid water-soluble fertilizer, the humic acids that utilizes microbial fermentation and obtain, compare with the mineral source humic acids, its function of regulating plant growth can be stronger, in addition, in this water soluble fertilizer N-P-K content also up to 15% ~ 35%.The biogas expel liquid waste of pig-breeding industry itself is exactly a kind of good liquid fertilizer, except nitrogenous phosphorus potassium, outside the humic acids, also contain the necessary various trace elements of crop, humic acids as the raw material extraction, the every advantage that had both kept the mineral source humic acid fertilizer, possesses the biologically active substance that the mineral source humic acids does not possess again, and avoided the destruction of exploitation mineral deposit to the Nature ecotope, it also is the degree of depth utilization to pig-breeding industry liquid debris, reduced the treatment cost of waste, and the low production cost of humic acids meets the national environmental protection agricultural, the strategic objective of ecological agriculture development and industry policy.The live pig large-scale cultivation field major part in the whole nation has methane-generating pit, if can take full advantage of this technology, can satisfy the humic acid water-soluble fertiliser production fully to the demand of humic acids, realizes also solving without the mineral source humic acids target in humic acid material source.Among the present invention the preparation of natural pond slag mud be utilize that pig-breeding industry or alternate manner obtain contain excrement sewage, the non-mineral source humic acids that obtains after treatment, is produced and is contained humic acid water-soluble fertilizer, meets the requirement of national sector standard NY1106-2010.
