Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a container for dehydration of a mixture of solid and water, for example, a water-containing mixture in which hydrophilic colloid particles are hydrophobized by treating a pollutant on a lake, the bottom of the sea floor or a pollutant with a purifying / separating agent.

[0002]

[Prior art]

 It is well known in the art to use a filter cloth to separate a mixture of solids and water. In addition, as a distribution packaging material, there has been conventionally known a packaging body including a packaging bag or a carrying bag in which a reinforcing belt and a hanging belt or rope are attached to a cloth bag made of polyethylene, polypropylene or the like.

[0003]

[Problems to be solved by the device]

 The conventional container made of a filter cloth for dehydration has only the purpose of dehydration itself, and is not only dehydrated or stored or transported, but also a dehydration bag that can be dehydrated, stored, transported and stored in one step. This is where the appearance of the body is desired.

[0004]

[Means for Solving the Problems]

 As a result of intensive studies to solve the above problems, the present invention has an outer bag and an inner bag as a storage bag for dehydration of a water-containing mixture, for example, a water-containing mixture obtained by hydrophobizing sludge, etc. The inventors have found that the problems described above can be solved by making it possible to transport and store only the same, and have reached the present invention. That is, the present invention is (1) a net-shaped storage body comprising an outer storage body and an inner storage body, the outer storage body having a suspending tool at an upper portion and an openable and closable fastener at a bottom portion, and A bottomed cloth container for dehydrating a water-containing mixture.When the inner container is housed in the outer container and the water-containing mixture is put into the inner container for dehydration, the bottom part of the outer container is A container for water removal, comprising closing the fastener and opening the bottom fastener of the outer container after dehydration so that the inner container containing the residual mixture can be taken out. (2) Outside The container for dehydration according to (1), wherein the container is a tubular mesh bag, and (3) the inside container is a tubular cloth bag made of a synthetic resin continuous filament non-woven fabric. (4) The inner container is a cloth bag made of a synthetic resin yarn knit. (1) The dewatering container according to (1), (5) the inner container is a cloth bag made of a disintegrating or corrosive material, and the dewatering container according to (1), and (6) the water-containing mixture. The present invention relates to the dewatering container according to (1), which is bottom mud or wastewater pollutants.

In the present invention, the outer container may have a tubular shape, and may be a cylindrical or polygonal tubular mesh bag. A suspending tool is provided on the upper portion of the outer container. Any hanging device can be used. A polyester or polyamide rope is used. In addition, a fastener is provided on the bottom, tighten the fastener to hold the inner container during dehydration, open the fastener after dehydration, take out only the inner container, and use it for transportation. . When the outer container is a net-like material, the material is knitted from a strong yarn, such as a synthetic resin yarn, such as a polyamide or polyester yarn. The inner container is a tubular cloth container having a bottom suitable for the outer container, for example, a bag, and a fastener is provided at the mouth of the container. The material of this inner container is made of synthetic resin fiber or cloth knitted with thread or non-woven fabric made of synthetic resin fiber for dehydration. Len continuous fiber nonwoven fabric is used. It can also be a collapsible or corrosive container. This is an inner bag for dewatering the bottom mud, and is preferably a collapsible or corrosive bag that can be reduced to the soil by being left in the soil for a long time. The material of the collapsible or corrosive inner container may be collapsible synthetic resin or cotton. Any water-containing mixture may be used, but it is particularly suitable for dehydration treatment of sediment sludge “sludge” and industrial wastewater pollutants accumulated in lakes, rivers and seabeds. For example, the purification / separation treatment agent can be put into bottom mud or industrial wastewater pollutants and used to treat a hydrous mixture obtained by hydrophobizing and separating sludges. The purification / separation treatment agent is, for example, an aqueous solution containing a divalent or trivalent iron salt, a trivalent metal salt and an alkaline earth metal salt as a main component, and a divalent or trivalent iron salt is a sulfur. Examples thereof include ferrous acid, ferric sulfate, and ferric chloride. As trivalent metal salts, aluminum sulfate [Al ₂ (SO ₄ ) ₃ ] and aluminum potassium sulfate [AlK (SO ₄ ) ₃ ]. Etc. The alkaline earth metal salts include magnesium chloride (MgCl ₂ · 6H ₂ O), calcium chloride (CaCl ₂ · 6H ₂ O) and the like.
