すべてにあってもよい。The present invention will be explained below with reference to the drawings. FIG. 1 is a sectional view showing one embodiment of the dental waste liquid treatment material of the present invention. 1 is a water-disintegrating paper, 2 is a water-soluble poval (1 and 2 are bonded together), 3 is a granular water-absorbing resin, 4 is a filler, and 5 is a heat-sealed portion. Although some parts are omitted in FIG. 1, the whole bag is shaped like a bag, and there is an opening on only one of the four sides around the bag, and that part is heat-sealed. The number and position of the heat-sealing parts vary depending on the shape of the processing material, particularly the number and position of the openings, and the heat-sealing parts may be located in any position as long as the contents including the water-absorbing resin can be sealed. Therefore, for example, in the case of a rectangular bag-shaped processing material, the material may be present on one or more of the four sides, or on all four sides.

I stacked two of these and heat-sealed the three edges to make a bag. 20 g of acrylic acid starch graft-based water absorbent resin "Sunwet IM-1000" (manufactured by Sanyo Kasei Co., Ltd.) and 80 g of granular clay were placed in this, and the opening was then heat-sealed (sealed) to form the dental waste liquid of the present invention. Made processed materials. This treated material is placed in the 2 liters of dental waste fluid containing gypsum accumulated in a special processing bag (inside the lower trap) attached to the "Gypsum Trap" dental waste fluid treatment device manufactured by Tokyo Giken Co., Ltd. Inserted, length 20cm, width 3c
Stir lightly with a wooden spatula. A dry solid (gelled product) about 3 mm in size was obtained in about 1 minute, and the sludge-like waste liquid, which was difficult to handle, could be converted into a solid that was easy to handle in a short time and easily.

である。[Effects of the Invention] The dental waste liquid treatment material of the present invention has the following effects. (1) Since the water-absorbing material is wrapped in water-soluble or water-disintegratable paper or film, it does not spill or generate dust when handled, unlike conventional methods. (2) When adding it to dental waste fluid, there is no need to measure the amount and sprinkle it as required in the past, so it is less time consuming and convenient. (3) Since it has a large water absorption capacity, only a small amount is required. (4) Even if pressure is applied from the outside after absorbing water, the absorbed moisture will not be released. Because of the above effects, the present invention is useful as a dental waste liquid treatment material and a dental waste liquid treatment method.
