The wastewater treatment material produced by the present invention is a material for water purification of rivers, lakes, seas, etc., as well as water for general agriculture, factory wastewater, purification of domestic wastewater discharged from households, livestock excreta treatment, and improvement of burning. Used as.

従来、工場排水は、浄化槽を通した後、河川に放流しており、家庭から出る生活排水は、受水槽に入れて沈殿させ、上澄み水を河川に放流している。しかし、これらの排水は十分に浄化されていない状態で放流されている場合も多く、植物に生育に悪影響を及ぼしたり、深刻な環境汚染を引き起こす等の弊害が生じている。また、家畜のし尿などは、そのまま河川に放流されている場合もあり、緊急の対策が必要になっている。このような排水を処理する排水処理材として、種々のものが開発されている。   Conventionally, factory wastewater passes through septic tanks and is then discharged into rivers, and domestic wastewater discharged from households is deposited in water-receiving tanks and the supernatant water is discharged into rivers. However, these wastewaters are often discharged in a state where they are not sufficiently purified, causing adverse effects such as adversely affecting the growth of plants and causing serious environmental pollution. In addition, livestock excreta and the like may be released into rivers as they are, and urgent measures are required. Various wastewater treatment materials for treating such wastewater have been developed.

しかしながら、従来の排水処理材は、使用時に溶解することがあり、良好な排水処理を得ることができないという課題があった。   However, the conventional wastewater treatment material may be dissolved during use, and there is a problem that a good wastewater treatment cannot be obtained.

次に図面を参照して、本発明の好ましい実施の形態に係る排水処理材の製造方法について詳細に説明する。まず最初に、排水処理材の原材料を準備する。排水処理材の原材料は、腐葉土、炭素粉、一般土、貝化石、鉄粉、炭素液である。なお、腐葉土は、汚泥を含むものでもよいし、腐葉土の代わりに汚泥を用いてもよい(以下「腐葉土及び/又は汚泥」という)。原材料のうち腐葉土は、水分調整及びミネラル分補給の役目を果たす。また、炭素粉は浄化作用、一般土は水分調整、貝化石はミネラル補給、鉄粉は漁礁の鉄分補給、炭素液は固化能力の増強の役目をそれぞれ果たす。   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.

次いで、これらの原材料を所定の比率で混合して攪拌する。攪拌時間は、30秒〜180秒以上とするのが好ましい。好ましい混合比率は、腐葉土及び/又は汚泥が40〜70容量%、一般土が5〜13容量%、炭素粉が1〜5容量%、貝化石が1〜5容量%、鉄粉が1〜5容量%、炭素液が1〜2容量%である。最も好ましい混合比率は、腐葉土及び/又は汚泥が70容量%、一般土が13容量%、炭素粉が5容量%、貝化石が5容量%、鉄粉が5容量%、炭素液が2容量%である。   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.

これらの原材料のうち、炭素粉は、炭素片を砕いて粉末状にしたもの、貝化石は、貝の化石を砕いて粉末状にしたものである。また、炭素液は、径が1×10-8mm〜1×10-6mmの炭素微粒子を所定量の水に混合して攪拌することによって生成される液体である。炭素液における炭素微粒子の割合は、全体の2容量%程度であるのが好ましい。 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.

なお、原材料の混合に際しては、腐葉土及び/又は汚泥、炭素粉、一般土、貝化石、鉄粉、炭素液を一緒に混合してもよいし、炭素液以外の原材料(腐葉土及び/又は汚泥、炭素粉、一般土、貝化石、鉄粉)をまず混合して、その後、炭素液を加えて混合するようにしてもよい。   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.

なお、海に使用する排水処理材については、腐葉土及び/又は汚泥は、含水率が30%〜60%のものを用いるのが好ましい。また、海に使用する排水処理材の腐葉土及び/又は汚泥として、ミネラル分の補給のため、食物残渣や植物性残渣(植物から出る残渣)を含むものを用いるのが好ましい(この場合の混合比率は、50〜70容量%以下とするのが好ましい)。   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).

次いで、上述のように混合し攪拌した材料に、固化材を添加して攪拌する。固化材としては、無機系の固化材を用いるのが好ましい。固化材の添加量は、混合し攪拌した材料の量に対して0.3容量%〜0.4容量%であるのが好ましい。固化材を添加すると、固化材がイオン化することにより、原材料が凝集固化するため、粘着性に優れ、浄化・蘇生する効果があり、溶解しにくい排水処理材が得られる。   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.

図2は、団粒構造を説明するための図である。団粒構造は、土粒子間に小さな間隙しか存在しない単粒構造とは異なり、小さな間隙と大きな間隙を併せ有するため、土粒子同士の結合が強固であり、崩れにくい土壌が得られるとともに、水はけや通気性が良好である等の特質を備えている。団粒構造を呈するように排水処理材を製造することにより、使用時に溶解しにくいという利点が得られるとともに、土壌改良材などとしても利用することができる。   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.

なお、以上のようにして製造された排水処理材が湿潤状態である場合には、温風等を用いて乾燥させるのが好ましい。   In addition, when the waste water treatment material manufactured as mentioned above is a wet state, it is preferable to dry it using warm air etc.
