Description of the Related Art For example, in a grease trap of a device for purifying waste water generated in a kitchen of a restaurant, when removing oil in the waste water, an oil adsorbent in a bag is put and floated on the liquid surface and left for a predetermined period. By doing so, there is a method of adsorbing and removing the oil on the liquid surface. As the oil adsorbent, there are a material composed only of natural fibers and a material in which natural fibers are impregnated with a water repellent (for example, JP-A-7-232061).

However, if most of the oil content has been removed by the previous cleaning and the bag is in the water state, when the bag-shaped oil adsorbent is loaded at this time, the bag-shaped oil adsorbent will be repelled. Since it absorbs water even if it has water, the bag-shaped oil adsorbent loses its water repellency early and easily sinks deeper than necessary in the liquid. It was lost.

かかるという問題点がある。In addition, in the material of the oil adsorbent, the oil adsorbent composed of only natural fibers can be incinerated without producing harmful substances and has good oil adsorbability, but also adsorbs water. As a result, there is a drawback that the oil adsorption rate decreases. On the other hand, the oil adsorbent in which the natural fiber is impregnated with the water repellent has an advantage that it can adsorb only the oil component without adsorbing the moisture and the oil adsorption rate can be increased, but it requires many steps in its production. However, there is a problem in that the material cost is also high.

る。A buoyant material made of closed-cell foamed plastic or the like is mixed in the crushed or crushed material in the bag body. Since this buoyant material assists the buoyancy of the oil adsorbent, immediately after cleaning, the oil adsorbent contains oil. Even if most of the water is removed and put on the surface of the drainage water, it absorbs less water and does not sink deeper than necessary at an early stage. It is possible to promote the adsorption of oil only. This oil adsorbent can avoid absorbing water as much as possible before the oil accumulates on the surface of the drainage liquid, and can adsorb only the oil as soon as the oil accumulates.

The crushed or crushed product 1 may be crushed only with a shredder or the like, but if it is further crushed with a mixer or the like, fluffing occurs on the surface of the waste paper, the surface area thereof is increased, and oil can be more easily adsorbed. However, waste paper is not preferable because if it is made into a fine powder, there will be no sufficient oil holding portion and the amount of oil absorbed will decrease.

砕物１により吸着されるのを促す効果がある。For example, as shown in FIG. 2, when one or two or more of the oil adsorbent P having the above-mentioned configuration is put into a grease trap or the like, the buoyancy of the buoyancy material 3 crushed or mixed in the crushed material 1 is exerted. As a result, it does not float above the liquid level of the drainage and does not sink deeper than necessary.Therefore, it is possible to avoid water absorption by submerging too deeply into the water as much as possible, and the floating state on the liquid level can be maintained for a long time. Since the oil is maintained, it has an effect of promoting only the oil on the liquid surface to permeate through the pores 2a of the bag body 2 and be crushed or adsorbed by the crushed material 1.

処分することが可能である。Further, the oil adsorbent P can bind the string-like member 4 to the upper edge of the tank 5 of the grease trap or the handle 7 of the upper edge of the partition plate 6 in the tank. This also prevents the oil adsorbent P from sinking deeper than necessary, so that water absorption due to deep sinking in water can be avoided as much as possible, and the floating state above the liquid level is ensured. Only the oil above can be effectively absorbed. Further, the binding of the string-shaped member 4 prevents the oil adsorbent P from flowing into or clogging the downstream tank 8 or the sewer pipe (not shown). Further, when the oil adsorbent P is collected after a predetermined use period, it can be easily collected by pulling the string-shaped member 4 and pulling it toward the hand. After collection, the oil adsorbent P can be incinerated.

It has the effect of promoting the adsorption of chisel. In addition, recycled paper can be used to save resources and can be manufactured at low cost.
After use, it can be incinerated without producing harmful substances.
