Description

[Detailed Description of the Invention] [I-Shijutsu-gen-no] Kiba E14 u, Kikiga-Kinbun't 2; It concerns the manufacturing method.

[Background technology]

In Japan, where there are many acidic soils, basic soil improvement agents are used, and therefore most of the soil improvement agents that have been provided to date are basic.

Coupled with the fact that soil conditioners are often neglected, the basicity of the soil progresses gradually over the years, and the pH of the soil reaches the optimum level for crops. There are concerns about the improvement of paulownia, and this is currently being discussed as a serious problem, and it is desirable to use acidic soil for soil improvement @ Paulownia. The decline in soil fertility due to the lack of ash content is also a current problem, and the decline in soil fertility due to the lack of ash content is also a problem, and the lack of funds for soil improvement is also a problem. Even in phrases η
One that contains organic components is desired.

In recent years, the slag produced in large quantities by steel mills has been used for self-efficiency, but for more than 30 years after the war, it has been used in large numbers mainly as road slag ballast, but in recent years, due to the restraint of public investment and Due to the same increase in the road paving rate, the number of uses has drastically decreased, and new usage methods based on the perspective of self-effective use are emerging.
It is currently being used as a mine slag 1.
It is used as a soil fertilizer and as a soil conditioner. Attempts have also been made to improve this ore-saver fence using methods disclosed in Japanese Patent Publication No. 50-26454. Is the slag basic depending on the basic substance it contains? The slag raw material and the soil improvement material were the only ones that were used as basic soil improvement materials.

[Purpose of FllJ] Is it possible to add h1 to the above points and use the entire slag as a raw material and as a mulch ingredient? The granular acidic slag fertilizer and its production method are described below.
The main purpose of the present invention is to provide a granular acidic mineral fertilizer that can be easily granulated and to make the drying process less difficult, and a method for producing the same. .

[Disclosure of the invention]

The granular hostile slag fertilizer according to the present invention is a pulverized product of one ore slag, and a part or two or more types of slag, such as alcohol fermentation waste liquid, concentrated seafood processing waste liquid, seratin purification waste liquid, pulp waste liquid, etc. A compound containing acidic waste and a pre-acid,
Or is it dispersive? I! I! ! The production method is to add a part or more of 11 parts of 11 hostile waste liquids containing perilla to the pulverized product of wind shavings, alcohol ft,) t+H liquid, marine product processing waste liquid box, seratin purification waste liquid, pulp waste liquid, etc. and mineral acid,
There is also a feature characterized by the ability to adjust the dispersion, hereinafter referred to as the present invention? Explain to ffjlf in detail 4.

Blast furnace slag and 'J7' slag can be used as slag, and this slag can be used in the form of powder and granules. The particle size of this crushed slag is between 70 mm (approximately 190μ) and 260 mm (approx.
It is desirable that the grain size is about 40%. Although slag is a multi-phase material that can be obtained stably and inexpensively despite the recent decline in steel production, it is possible to obtain it stably and inexpensively. ?Mix and react.

14, fishery processing waste liquid, gelatin purification waste liquid, baru waste liquid, etc. can be used, and one of these can be used alone or in a mixture of two or more extracts.

The alcohol fermentation waste liquid, which is one of the waste liquids containing acid and sea lions, is sold at Alcoholic Fermentation Industry, with annual sales of approximately 7,000 yen.
Of the 0 tons discharged, 18,000 tons per year are subject to culm or seaweed, and this alcoholic fermentation waste has also been established and is available in the United States. Other items such as barra 1 light (fri etc.) can also be obtained at a low price of 11 pieces.

The crushed mineral acids are Tsukuda acid, phosphoric acid, and nitric acid. undesirable because of
There is also one 4' unit.

Is it possible to use acidic waste liquid and mineral acid in the ground material of sashimi and mineral acid? When added, the alkali content of the water contained in the slag powder reacts with organic acids and mineral acids, and some of it becomes magnesium acid salts, etc., and when the mineral acid is sulfuric acid, for example, it is dissolved in the slag. The component composition was changed to partial circle J to calcium and magnesium sulfate, which worsened N11 absorption. Here, the extraction pH of Alco-J and I Sakaki vinegar hL liquid is 47-5.
3, fisheries processing waste (Ikue, rice has a pH of about 4.5,
Gelatin refining waste liquid has a pH of 4 to 4.5, and pulp has a pH of 4 to 4.5, and acidic waste liquid containing some substances alone will neutralize the alkaline aroma eluted from mineral slag. This is the limit, and the alkali contained inside the grains must be adjusted to acidity by adding mineral acid.

In addition, since a mixture of pulverized mineral slag and acidic waste containing acid waste such as alcohol fermentation waste liquid is used in large quantities, it is extremely difficult to granulate it into a slurry. However, the addition of lactate further promotes the grain effect and facilitates granulation.'1- That is,
For example, when used as a mineral acid in grinding, calcium sulfate and magnesium chloride are produced;
It is good for the action of condensing S itself, and the water content becomes crystallized water.

〔Effect of the invention〕

As mentioned above, the crushed mineral slag is mixed with the acidic waste liquid containing organic matter and mineral acid, resulting in a 98-year acidity υ1.
By applying it to soil that is too basic, it is possible to improve the pH to an appropriate level. By replenishing the missing materials, it promotes the growth of microorganisms in the soil and the aggregation of the cultivated soil. Historically, it has been reported that some minerals containing acid and mineral acids are produced by reaction with components in the mine slag, and are treated as trj, I'IJ, which is a relative part of nitrogen. , ¥ acid or potassium-containing wool fertilizer J'lt is obtained. By adding mineral acid, the water molecules in the mixture h'i as crystal water.
The synergistic effect of the acid salt containing inorganic substances in addition to IX and evaporation with heat makes it easy to granulate, and therefore, the granulation becomes easy.・In the present invention, the surface portion of the crushed mineral slag is acidic. Granular acidic ore waste that has been acidified by the action of heat and mineral acids is mostly composed of neutral silicate compounds, and contains organic matter related to "non-explosion". After application, the surface of the crushed slag is used to adjust the pH of the soil to the appropriate level for crop growth, and even after application, it is a silicate compound that contains (4(iχ) acid) in the soil. Even if soil damage occurs, the fertilizer according to the present invention can be used in people's minds to prevent soil damage that is appropriate for crop growth.
A notable feature is that it can neutralize H. In addition, in the case of "unexploded or unexplored", the slag and slag that are produced in many places as industrial fruits are dumped in many places.
