Abstract

The present invention relates to a furfural fertilizer and the preparation thereof, the furfural fertilizer is prepared from furfural residue as a main raw materal, mud and chemical fertilizers, wherein the mud and the chemical fertilizers are used for being matched with the main raw materal. The present invention solves industrial waste in an agricultural use way, provides a new method for environment treatment, and opens up a new approach for the production of fertilizers. The present invention has the advantages of wide raw material source, simple device, little investment and easy preparation, and the product is high quality fertilizer having organic substances and inorganic substances.

Description

Chaff fertilizer and its making method
The invention belongs to a kind of organic-inorganic composite fertilizer and manufacturing technology thereof, belong to field of fertilizer manufacturing, also is to administer the industrial waste new way.
The fertilizer that uses has two big classes substantially at present: the one, and inorganic chemical fertilizer, as: urea, ammonium sulfate, Repone K, ammonium nitrate etc., utilize industrial raw material, by big industrial production, its nutrient is more single, and composite chemical fertilizer rises at present, welcome by wide farmers, but composite chemical fertilizer can only solve the coordination problem of nitrogen, phosphorus, potassium three elements, fails to solve organic and inorganic dual-purpose problem.Composite chemical fertilizer employed binding agent in manufacturing processed mostly is clay, there is no fertilizer efficiency, there is not the effect of improving the soil, on the contrary, iron in the clay, aluminum ion are harmful on the contrary to soil, and minority composite fertilizer uses organism such as peat, weathered coal to be binding agent, and this class material is a natural resources, can not regenerate limited amount.
The 2nd, fertilizer: by planting, support, amass, make farm manure and green manure, this fertilizer can be increase soil fertility, keep soil fertility not wane in thousand, and present this fertiliser production level is low, of poor benefits, economic benefit is not high, heavy, have peculiar smell, unhygienic, use and transport inconvenience, be difficult to support the modern agriculture of high development.At present, it is still the important source that increases the soil organism.Industrial wastes such as furfural dregs, filter mud and coal ash in the past peasant also had by chance as base manure, because its investing method, economic benefit is low and be eliminated gradually.
Because a large amount of inputs of chemical fertilizer in recent years, and organic minimizing year by year, soil organic matter content is more and more lower, and soil is increasing to chemical fertilizer " appetite ", and the unit stimulation ratio of chemical fertilizer is more and more lower, the obvious souring hardening of soil, seriously influence the development of China's agriculture production, the chemical fertilizer industry development is fast more, and fertilizer production is many more, modern agriculture production advances more, and this contradiction is outstanding more.Depend merely on traditional kind, support, long-pending, this low input of system, the inefficient soil organism that replenishes be to be difficult to reverse the situation that the present soil organism lacks.
The composite fertilizer that purpose of the present invention provides a kind of organic and inorganic to have concurrently, this fertilizer has the fertilizer efficiency nutrient that chemical fertilizer has, and has the fertilizer efficiency effect of fertilizer again, and it is single to overcome the chemical fertilizer nutrient, and the inefficient deficiency of organic fertilizer production.The present invention adopts the agricultural use mode to handle industrial waste, makes it to form fertilizer, has both solved present industrial waste environment protection treating problem anxious to be solved, has opened up the fertiliser production new way again.
The present invention has generally investigated United States Patent (USP) (DIALOG 340) and world patent (DIALOG 351) document is not found similar patent documentation through computer search portion of institute of Guangdong Province scientific-technical information.
The present invention is that main raw material is allocated an amount of filter mud and chemical fertilizer into and is made after evenly with the furfural dregs.
Furfural dregs is meant and extracts remaining waste residue behind the furfural, comprises and use bagasse that cotton core and other farm crop are produced the waste residue behind the furfural.
Filter mud is meant and comprises sweet tea, the sugar mill mud that cane sugar manufacture filter mud and carbonatation process, sulfitation process craft production are produced.It is a raw material of producing chaff fertilizer, is again good binding agent.
Flyash: refer to industrial coal ash, as the boiler coal ash of power plant or nitrogen fertilizer plant.
Implementation method of the present invention
1, composition of raw materials
Furfural dregs: 50%-70%(weight), water content is in 60%(weight) below, the pH value is about 1.5.
Filter mud: 8-25%(weight), water content is in 40%(weight) below, between the pH value 10-7.
Flyash: can replace the 1/3-1/2 of filter mud, water content is less than 5%(weight), the pH value is about 8.0.
Chemical fertilizer 10-25%(weight) (as urea, ammonium sulfate, bicarbonate of ammonia, Repone K, calcium superphosphate, ground phosphate rock etc.).
2, manufacture craft
1. getting water content is 60%(weight) below, the pH value is in the furfural dregs 50-70%(weight about 1.5) with water content be 40%(weight) below, pH is the sugar mill mud 8-25%(weight of 10-7) behind the mixing, again with the chemical fertilizer 10-25%(weight of mixing) mix, make granular or pie, drying obtains fertilizer product.(, ground phosphate rock is put in mixes stack retting making again after two weeks in back in the furfural dregs earlier) if use ground phosphate rock.
2. getting water content is 60%(weight) below, pH is in the furfural dregs 50-70%(weight about 1.5) with water content be 40%(weight) below, pH is that 10-7 system chaff filter mud and water content are less than 5%(weight), pH is about 8.0 the common 8-25%(weight of flyash), wherein flyash accounts for 1/2-1/3, and mixing is complete, again with the chemical fertilizer 10-25%(weight of mixing) mix, make granular or pie, drying obtains fertilizer product.
Through test, of equal value or etc. under the nitrogen condition, chaff fertilizer is better than peanut press pulp to the fertilizer efficiency of vegetables, and is approaching with import composite fertilizer (15-15-15) fertilizer efficiency, but chaff fertilizer can make the vegetables stalk sturdy, the thick viridescent of leaf reaches results ahead of time, and can reduce nitrate salts content of vegetable, and prolong the vegetables preservation period, improve the quality of vegetable quality, in the low red soil of basic fertility, chaff fertilizer obviously is better than composite fertilizer to paddy rice dirt fertilizer efficiency.
Present device is simple, less investment, make easily, its main raw material is the residuum furfural dregs behind the making furfural, furfural is the very wide industrial chemicals of a kind of domestic and international demand, and factory divides cloth cover very wide, and furfural dregs environmental pollution problem still can't solve at present, the present invention solves industrial waste by agricultural use, and opens up the fertiliser production new way.
