It is a liquid produced by mixing ⁶ mm carbon fine particles with a predetermined amount of water and stirring.

  The method for producing a wastewater treatment material according to claim 5 of the present invention was produced in the method according to any one of claims 1 to 4, in the second stage, or subsequent to the second stage. It includes drying the wastewater treatment material with warm air.

  Since the wastewater treatment material produced by the method of the present invention exhibits an aggregate structure, it does not dissolve during use, and a good wastewater treatment effect can be obtained. When wastewater treatment is performed using the wastewater treatment material produced by the method of the present invention, an oxygen-rich environment can be provided, and nutrients such as minerals can be replenished.

  Next, a method for producing a wastewater treatment material according to a preferred embodiment of the present invention will be described in detail with reference to the drawings. First, prepare raw materials for wastewater treatment materials. The raw materials for the wastewater treatment material are humus, carbon powder, general soil, shell fossil, iron powder, and carbon liquid. The humus may contain sludge, or sludge may be used in place of the humus (hereinafter referred to as “humus and / or sludge”). Of the raw materials, humus plays a role in moisture adjustment and mineral supplementation. Carbon powder plays a role in purifying, general soil moisture, mineral fossil shell replenishment, iron powder replenishment of fishing reef iron, and carbon solution plays a role in enhancing solidification capacity.

  Next, these raw materials are mixed and stirred at a predetermined ratio. The stirring time is preferably 30 seconds to 180 seconds or more. The preferred mixing ratio is 40 to 70% by volume for humus and / or sludge, 5 to 13% by volume for general soil, 1 to 5% by volume for carbon powder, 1 to 5% by volume for fossil shells, and 1 to 5% for iron powder. Volume%, carbon liquid is 1-2 volume%. The most preferred mixing ratios are 70% by volume for humus and / or sludge, 13% by volume for general soil, 5% by volume for carbon powder, 5% by volume for shell fossil, 5% by volume for iron powder, and 2% by volume for carbon liquid. It is.

Among these raw materials, the carbon powder is a powder obtained by pulverizing a carbon piece, and the shell fossil is a powder obtained by pulverizing a fossil shellfish. The carbon liquid is a liquid produced by mixing carbon fine particles having a diameter of 1 × 10 ⁻⁸ mm to 1 × 10 ⁻⁶ mm with a predetermined amount of water and stirring. The proportion of the carbon fine particles in the carbon liquid is preferably about 2% by volume of the whole.

  In mixing raw materials, humus and / or sludge, carbon powder, general soil, shell fossil, iron powder, carbon liquid may be mixed together, or raw materials other than carbon liquid (humic soil and / or sludge, Carbon powder, general earth, shell fossil, iron powder) may be mixed first, and then the carbon liquid may be added and mixed.

  In addition, about the wastewater treatment material used for the sea, it is preferable to use humus and / or sludge with a moisture content of 30% to 60%. Moreover, it is preferable to use the thing containing a food residue and a vegetable residue (residue which comes from a plant) as a humus and / or sludge of the wastewater treatment material used for the sea for the supplementation of a mineral content (mixing ratio in this case) Is preferably 50 to 70% by volume or less).

  Next, the solidifying material is added to the material mixed and stirred as described above and stirred. As the solidifying material, it is preferable to use an inorganic solidifying material. The addition amount of the solidifying material is preferably 0.3% by volume to 0.4% by volume with respect to the amount of the material mixed and stirred. When the solidifying material is added, since the raw material is agglomerated and solidified by ionizing the solidifying material, a wastewater treatment material that is excellent in adhesiveness, has an effect of purifying and reviving, and hardly dissolves is obtained.

  FIG. 2 is a diagram for explaining the aggregate structure. Unlike a single-grain structure in which there are only small gaps between soil particles, the aggregate structure has both small and large gaps, so that the soil particles are strongly bonded to each other, and a soil that does not collapse easily is obtained and drained. And features such as good ventilation. By producing the wastewater treatment material so as to exhibit a aggregate structure, it is possible to obtain an advantage that it is difficult to dissolve during use, and it can also be used as a soil improvement material.
