Thus, if the water treatment system according to the present invention is used, the apparatus is not complicated and does not become huge, so that the cost of constructing the water treatment facility can be reduced, and the water treatment points scattered in each area It has an excellent effect that it can respond with mobility.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings.

  First, the coagulating sedimentation agent 1 used in the present invention will be described.

  The coagulating sedimentation agent 1 of the present invention mainly uses wooden waste materials. For example, wood waste wood chips and the like are burned at a high temperature to cause so-called fly ashing (ashing). Then, a fine gray inorganic powdered carbide having a specific gravity of 0.60 to 0.65 can be generated.

  In the present invention, wooden waste materials are mainly used, so that the waste materials are present in large quantities, and the production cost of the coagulating sedimentation agent 1 itself can be extremely reduced.

  In addition, waste materials generated in the paper manufacturing process, so-called paper sludge, are also burned at a high temperature, and so-called fly ashing (ashing) is performed. As a result, fine gray inorganic powder carbide having a specific gravity of 0.60 to 0.65 can be produced. The paper sludge is also present in such a large amount that it becomes extremely difficult to dispose of it, and the production cost of the coagulating sedimentation agent 1 according to the present invention can be made extremely low.

Thus, the aggregated sedimentation agent of the present invention is prepared by mixing the powdered carbide of the wood waste material, the powdered carbide of the paper sludge, and a predetermined adhesive substance, for example, an additive such as an alkali adjusting agent, a buffering agent, and a solidifying aid. 1 is formed.
Here, the mixing ratio of the powdered carbide of the wood waste material and the powdered carbide of the paper sludge and the adhesive substance is approximately 70% for the powdered carbide material of the wood waste material, approximately 20% for the powdered carbide material of the paper sludge, and for bonding The substance is approximately 10%.

  However, this is only a standard mixing ratio, depending on the properties of the target water to be treated, the powdered carbide of wood waste wood is in the range of approximately 90% to 40%, and the powdered carbide of paper sludge is approximately 40%. The ratio may be changed within a range of 5%, and the proportion of the adhesive substance may be changed within a range of approximately 20% to several percent.

  Here, the manufacturing process of the powdered carbide of the said wooden waste material and the powdered carbide of paper sludge is demonstrated.

  First, it comprises a step of drying wooden waste materials and, for example, clay-like paper sludge, followed by a temperature raising step, and a carbonization step for processing into fine powdered carbides by firing at a high temperature.

  For their chemical properties, an acidity correction effect is expected. Since the powdered carbide is alkaline, it can be neutralized by reducing the acidity of the water to be treated, and for example, good growth of various crops can be expected with the water to be treated according to the present invention.

  It is thought that the pores of this powdered carbide also have pores as small as a few nanometers derived from inorganic materials. This powdered carbide is excellent in water absorption, has high functionality such as deodorization and adsorption, and is inexpensive. Can be manufactured.

  Moreover, the main feature of the coagulating sedimentation agent 1 of the present invention is that the main component thereof is so-called fly ash (ash baked at high temperature) as described above.

  In other words, powdered carbide is a fine inorganic powder with a small specific gravity, which promotes agglomeration in the water to be treated by mixing well with substances in the water to be treated, thereby forming porous soil particles. It will be.

  The fly ash and paper sludge incinerated ash, which are the main components of the coagulating sedimentation agent 1 according to the present invention, have a strong water absorption action and have a pozzolanic activity (react with water and solidify under chemical stimulation). Therefore, long-term strength can be expressed by mixing well with substances such as soil particles in the water to be treated and agglomerating.

  For fly ash and paper sludge incineration ash, an ethrin guide is generated by a hydration reaction. The generated ethrin guide is a needle-like crystal and expresses strength by combining various substances such as soil particles contained in the water to be treated.

  Furthermore, if a component having an ion exchange action is added as an additive, hydrophilic ions such as Na and K in the fine particles forming the soil particles and the like can be exchanged, and even fine particles can be further aggregated.

  Thus, since the intensity | strength of agglomeration is expressed by the production | generation of an etrin guide or a pozzolanic reaction, the soil particle etc. in process target water will agglomerate firmly, and will settle.

  By the way, the soil particles in the muddy water are floating in the water with a negative charge. Negative particles repel each other and decompose, causing turbidity.

  The muddy water contains organic impurities in addition to soil particles. In addition, the soil particles also contain ions that are easily compatible with water.

  Here, the coagulating sedimentation agent 1 according to the present invention has a positive charge, and aggregates the soil particles in water to form a floc. In addition, organic impurities and the like are aggregated, taken into the flocs, and settled as large flocs.

It should be noted that ions that are readily compatible with water are released into the water, and flocs are less likely to be compatible with water, so that they are not dispersed again in water.
That is, when the coagulating sedimentation agent 1 according to the present invention is added to the sewage, the positive ions of the coagulation sedimentation agent 1 and the negative ions of the soil particles in the sewage are electrically attracted and combined to form coupled particles. At that time, since the hydrophilic (easy to be compatible with water) ions contained in the soil particles are ion-exchanged, the binding particles are hydrophobic (not easily compatible with water).

  Further, the binding particles are electrically neutralized and lose their charge. Further, the bonded particles are adsorbed to form larger particles and settle in water.

  Since the binding particles and the particles formed by the adsorption of these particles have a strong binding force and are hydrophobic, water cannot enter between the particles, so that these particles may be dispersed in water again. There is no.

  The outline of the ettring guide will be explained. The term ettringai refers to a substance that draws long-term strength by the pozzolanic reaction with the pozzolanic substance in the soil particles in the end. Mineral name of the compound that can be expressed).

  As described above, the soil particles in the water to be treated are involved in the generation of the etrin guide while reacting with the coagulating sedimentation agent 1 according to the present invention.

  Then, after the reaction is completed, it does not exist as the size of the conventional soil particle itself, and a new mineral with a large shape is generated by the relationship of the soil particle itself.

  Therefore, even after continuous pressure or deterioration applied from the outside, it does not return to the same particle size (small size) as before.

  As described above, the fly ash constituting the coagulating sedimentation agent 1 of the present invention undergoes a hydration reaction by the hydrated mineral, and promptly generates the above-described ethrin guide.

  Since the generation of ettlin guide works to reduce the moisture content of the soil, the soil particles in the water to be treated are rapidly aggregated while surrounding fly ash and soil particles.

  Furthermore, as described above, the hydrate produced by the above-mentioned hydration reaction reacts with minerals of soil particles (pozzolanic reaction) to form stronger aggregates.

  Next, the system of the present invention will be described.

  FIG. 1 shows the system that is not mounted on a vehicle.

  FIG. 2 shows an example in which the apparatus constituting the system is an in-vehicle apparatus. A truck, a tractor, or the like is generally used as the vehicle 2, and the apparatus according to the present invention is mounted on the loading platform 3 at the rear.

  Therefore, a storage tank 4 that takes in and stores the water 5 to be treated is mounted on the loading platform 3 of the vehicle 2.

  A water absorption hose 6 is attached to the rear end of the storage tank 4, and the water to be treated 5 is sucked into the storage tank 4 by the water supply hose 6.

  After a predetermined amount of water 5 to be treated is stored in the storage tank 4, the agglomerated sedimentation agent 1 described above is sucked by the water supply hose 6 and sent into the storage tank 4 as shown in FIG. Step 100, Step 102).

  After feeding the coagulating sedimentation agent 1 as shown in FIG. 4, outside air 7 is sucked in by the pause hose 6 and air is stirred in the storage tank 4 (see FIG. 5: step 104 in FIG. 7).

Then, after this air agitation, the agglomerated sedimentation agent 1 and soil particles of the water to be treated 5 are aggregated after a predetermined time, and the aggregate 7 is located below the storage tank 4 as shown in FIG. To settle.
The supernatant of the processing target water 5 existing above the settled aggregate 8 is drained by a drain hose (not shown), and then the aggregate 8 is discharged to the outside (step 106 in FIG. 7). .

In addition, depending on the degree of treatment of the treatment target water 5, the type of treatment target water, and the like, it is conceivable to repeat the above steps a plurality of times (see FIG. 7).

  The water treatment system according to the invention is applied not only to purification of factory wastewater, water in ponds and reservoirs, but also to water and mud separation work for mud generated in civil engineering works such as tunnels. And by separating water and mud, the separated purified water can be drained without affecting the environment. Furthermore, since the separated mud becomes soil, it can be dehydrated and used in the same way as ordinary soil.

  Furthermore, in the event of a disaster, when water is needed, river water or the like can be purified by the system of the present invention and used for purposes other than drinking water.

In addition, the system of the present invention also functions effectively for the treatment of abrasive treated water, the treated water of rice and vegetables, the treatment of hot spring water, and the so-called combined septic tank water treatment.
