水分多量に含む汚泥の脱水方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a method for dewatering sludge containing a large amount of water.
従来の汚泥の脱水方法は、次の二つの方法が一
般的である。 The following two methods are generally used as conventional methods for dewatering sludge.
(イ) 現在の海汚泥繊維汚泥等は石灰粉を混入して
水部分を石灰で吸取つて水分を無くす。(b) Current sea sludge, fiber sludge, etc. are mixed with lime powder and the water portion is absorbed by the lime to eliminate moisture.
(ロ) 自然脱水をまつている。(b) Encourages natural dehydration.
しかしながら、上記(イ)の方法は、石灰粉のコス
トが高く、又、処理後の汚泥の処理に困る。又、
上記(ロ)の方法は、時間がかかりすぎる。 However, in the method (a) above, the cost of lime powder is high, and it is difficult to dispose of the sludge after treatment. or,
The method (b) above takes too much time.

れるという思想にもとづいて構成される。次に図
面にもとづいてこの発明の一実施例を説明する。 This invention was made based on these problems. That is, when an elastic material such as Styrofoam, which is discarded as waste, is crushed into small pieces and mixed into sludge, the Styrofoam pieces are sequentially compressed into the sludge, creating voids around the Styrofoam and causing the sludge to contain the styrofoam. Moisture aggregates. The system is constructed based on the idea that these voids communicate with each other one after another to form a water passage, and water that has aggregated around the Styrofoam is removed to the outside of the sludge through the dewatering holes. Next, an embodiment of the present invention will be described based on the drawings.

部に排出されるのである。 In FIG. 1, 1 is a container having dehydration holes 2 on four sides and at the bottom. As shown in Fig. 2, water-containing sludge 3 is put into this container 1, and then styrofoam particles as elastic pieces are added (third stage).
Next, the mixture is mixed using an appropriate method and left for a certain period of time. Then, water in the sludge sequentially oozes out from the dewatering holes 2, and the sludge is dehydrated. That is, the fifth
As shown in the figure, the elastic pieces (styrofoam particles) 4 thrown into the sludge 3 are compressed by the surrounding pressure to form voids 4a around them.
As the water in the sludge coagulates, the voids 4a are connected to form a kind of water passage, and only the water is discharged to the outside of the container 1 from the dewatering hole 2 in contact with the end of this water passage.
