Description

  The present invention relates to a liquid fertilizer manufacturing method and a liquid fertilizer manufacturing system for manufacturing liquid fertilizer suitable for crop cultivation from organic waste.

  Currently, organic waste such as garbage is usually incinerated as combustible waste. This incineration process causes various environmental pollutions such as increased financial burden, incineration ash treatment, and generation of dioxins. In addition, livestock farmers are obliged to properly treat manure, which places a heavy burden on livestock farmers. On the other hand, if organic matter is appropriately processed and composted, it becomes an excellent organic fertilizer. It is said that the fertility of farmland has been reduced by chemical fertilizers and pesticides, and the application of organic fertilizers is becoming important.

Conventionally, a technique for generating liquid fertilizer (liquid fertilizer) from organic waste such as raw garbage is known. The processing methods used as fertilizers for organic waste can be broadly classified into four types: activated sludge method, methane fermentation, high temperature fermentation, and raw urine. In any case, the liquid fertilizer obtained from each is used in one type.
FIG. 4 shows an example of the prior art. Conventionally, as shown in FIG. 4, out of the fertilizer raw material 1 made of organic waste, the cocoon 2 or livestock manure 3 is supplied to the methane fermentation treatment device 5 and methane fermented to produce the liquid fertilizer 10. On the other hand, livestock manure 3 or manure 4 was supplied to the aerobic fermentation and enzyme treatment apparatus 7 and aerobic fermentation and enzyme treatment were performed to produce liquid fertilizer 11. Farmers use either liquid fertilizer 10 or liquid fertilizer 11 manufactured in this way.

Patent Documents 1, 2, 3 and Non-Patent Document 1 disclose examples of techniques for producing liquid fertilizer from organic waste in this way.

  By the way, in the fertilizer used by crop cultivation, the fertilization effect characteristic, ie, the duration which acts as a fertilizer, is an important factor. Depending on the cultivation conditions of the crop, you may want to apply the fertilizer quickly or slowly.If you want to use it quickly, use a fertilizer with a short fertilizer, and if you want to use it slowly, use a fertilizer with a long fertilizer. I will use it. For example, in the cultivation of rice, the first fertilizer (original fertilizer) to be used works for a long period (for example, 1 to 2 months), so-called fertilizer with a long fertilization effect is required, and fertilizer that is given in the middle of cultivation (topdressing) Requires a fertilizer with a short fertilizer effect. In addition, suitable fertilizers are required according to the crops to be cultivated.

  The liquid fertilization by methane fermentation mentioned above continues the fertilization effect for a long period (for example, 1 month or more). Liquid fertilization by high-temperature fermentation has a short fertilization effect. For example, when put in a paddy field, the fertilization effect disappears within one week. At present, only one type of treatment method is adopted in each local government and company, and even if liquid fertilizer is produced from organic waste, there is only one type, so it will be inappropriate. For example, when liquid fertilizer suitable for rice cultivation is used for vegetable cultivation, good vegetables cannot be produced.

  The production of liquid manure from organic waste is extremely beneficial because it promotes the expansion of effective use (reuse) of organic waste, activation of agriculture, and suppression of environmental pollution. However, as described above, the current liquid fertilizer is a liquid fertilizer that is limited in type and whose fertilization characteristics are specified, and thus cannot be effectively used. Moreover, it is desired that each fertilizer component contained in liquid fertilizer is also optimal.

  In view of the above, the present invention provides a liquid fertilizer that enables the control of fertilizer effect and the control of fertilizer components in the production of liquid fertilizer from organic waste, and enables the production of liquid fertilizer suitable for various crop cultivation.

The liquid fertilizer has fast-acting properties (so-called liquid fertilizer with short fertilizer effect). By selecting the processing route of the fertilizer raw material, the fertilization effect characteristics of the liquid fertilizer obtained can be controlled. Moreover, the fertilizer component of liquid fertilizer can be controlled by selectively adding the fertilizer component for adjustment to the obtained liquid fertilizer.

Methane fermentation is a methane fermenter in which organic waste such as straw is finely pulverized and slurried, and the outside air is blocked (anaerobic state) and kept at a temperature suitable for fermentation (about 35 ° C to 55 ° C). It is carried out using bacteria such as methane bacteria. The organic matter contained in the slurry is decomposed by the methane fermentation treatment to produce biogas and liquid fertilizer.
Aerobic fermentation is performed by supplying aerobic bacteria (microorganisms) and air (oxygen) to organic waste such as manure and livestock manure. Primary fermentation supplies sufficient air to increase microorganisms and rapidly decompose organic matter. In the secondary fermentation, more various microorganisms appear and mature while the temperature is lowered.
Enzymatic treatment is a method of performing aerobic fermentation by adding aerobic bacteria and degrading enzymes to organic waste such as manure and livestock manure and supplying air (oxygen).
