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 that one can promote crop growthing development, improves farm crop resistance and quality thereof, the multifunctional fertilizers of increasing both production and income; In addition, take humic acids as raw material, a lot of other fertilizer containing humic acids can be derived.
The existing fertilizer containing humic acids performs according to People's Republic of China's industry standard (NY1106-2010), and its greatest problem is that humic acids source is also only limitted to natural mineral source humic acids, is extract from the peat composed of rotten mosses, peat, brown coal or weathered coal and obtain.Be no matter which kind of humic acids source above-mentioned, be all exploitation mineral sources material, obtains humic acids through extraction, all bring for cost to sacrifice natural ecological environment, and these resources are all limited, thus its prospect is also limited, and its development is unsustainable.Country was from 2008, and the outlet of restriction humic acids is exactly the decision made based on protecting the humic acids Mineral resources of China's preciousness.And now having become large source of pollution containing excrement sewage, traditional treatment process energy consumption is high, of poor benefits, and has secondary pollution.
Summary of the invention
The object of the present invention is to provide humic acid water-soluble liquid fertilizer of a kind of, energy-conserving and environment-protective simple containing non-mineral source humic acids and preparation method 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, is characterized in that, fills a prescription as follows: 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, wherein
The preparation method of described natural pond slag mud is: will containing excrement sewage separating dry space from moist space, the liquid obtained anaerobically fermenting in tank for sewage gas, produce biogas and biogas waste water, biogas waste water filtering is made solid-liquid separation, and the supernatant liquor and the non-mineral source humic acids that obtain biogas waste water roll over the natural pond slag mud that contents on dry basis is 10% ~ 30%.
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 source humic acid water-soluble liquid fertilizer of the present invention, is characterized in that:
By described formula, urea, phosphoric acid are joined in the supernatant liquor of biogas waste water, stir, make urea, phosphoric acid generation chelatropic reaction, then add potassium hydroxide, stir, after abundant reaction, add the natural pond slag mud that non-mineral source humic acids folding contents on dry basis is 10% ~ 30%, fully mix, after stirring, obtain the Water-soluble liquid fertilizer containing humic acids.
A technical scheme tool in technique scheme has the following advantages or beneficial effect: what this invention was different from the past utilizes mineral sources humic acids as the method and the path that produce humic acid water-soluble fertilizer, utilize fermentable and the humic acids obtained, compared with mineral sources humic acids, the function of its regulating crop growth can be stronger, in addition, in this water soluble fertilizer N-P-K content also up to 15% ~ 35%.Biogas expel liquid waste inherently a kind of well liquid fertilizer of pig-breeding industry, except Nitrogen-and Phosphorus-containing potassium, outside humic acids, also containing the necessary various trace elements of crop, as the humic acids that raw material extracts, both every advantage of mineral sources humic acid fertilizer had been maintained, possesses again the biologically active substance that mineral sources humic acids does not possess, and avoid exploitation mineral deposit to the destruction of the Nature ecotope, also be the deep exploitation to pig-breeding industry liquid debris, decrease the treatment cost of waste, and the low production cost of humic acids, meet national environmental protection agricultural, the strategic objective of ecological agriculture development and industry policy.The live pig scale livestock farming major part in the whole nation has methane-generating pit, if make full use of this technology, can meet the demand of humic acid water-soluble fertiliser production to humic acids completely, realizes the target that also can solve humic acid material source without mineral sources humic acids.In the present invention the preparation of natural pond slag mud be utilize pig-breeding industry or alternate manner to obtain containing excrement sewage, the non-mineral source humic acids obtained, after treatment, produces containing humic acid water-soluble fertilizer, meets the requirement of national sector standard NY1106-2010.
