状態で廃棄物へ廃棄処理されていた。It removes garbage such as empty cans and bottles to obtain clean intake water, but at the same time, another major role is to remove jellyfish (water carriers) that occur in large quantities in seawater depending on the season. A large amount of jellyfish were generated, and the recovered jellyfish were disposed of as waste.

脱水固化処理方法や装置の実現が渇望されていた。However, the jellyfish that are removed and collected in large quantities contain a large amount of water with a small amount of solid content, and if they are disposed of as waste in that state, they will cause environmental pollution by emitting bad odors due to decomposition, and it will be difficult to transport the jellyfish. The economic burden of increasing costs and securing a disposal site is also extremely large, and there has been a strong desire for a simple method and device for dehydrating and solidifying these jellyfish.

あとのケーキを焼却または廃棄することとした。In order to solve the above problems, the method for dehydrating and solidifying jellyfish of the present invention involves placing jellyfish in a mixer with an impeller that rotates at high speed, crushing them into small pieces, and then adding a flocculant to the suspended water and stirring. It was decided that the coagulated and precipitated sludge would be dehydrated using a dehydrator, and the dehydrated cake would be incinerated or discarded.

The solidified sludge is discharged from the bottom of the settling tank, while
The supernatant liquid is discharged after overflowing from the upper end of the outer periphery of the settling tank. Although the discharged sludge is mainly composed of concentrated solids, it still contains a large amount of water, so it is put into a dehydrator and the dehydrated cake is incinerated or discarded. By the above operation, water can be separated from the jellyfish containing a large amount of water, and only the remaining solid matter can be incinerated or disposed of.The separated water can be discharged to the sewer, so the solid content of the jellyfish has been reduced quantitatively. It is economically advantageous because only jellyfish can be treated, and there is less environmental pollution compared to leaving jellyfish as living organisms.

の下部に設けた排出口３ｆより排出される。The jellyfish is first put into the mixer 2, where it is finely divided by the impeller 2a that rotates at high speed, and the gel-like suspension water consisting of the solid content of the jellyfish and water is sent to the settling tank 3 through the inlet 3a. For example, a polymer flocculant or an inorganic flocculant such as sulfate is added to an appropriate dissolved concentration in the range of 0.1 to 1.0% through the addition device 3d, and stirred at low speed. After about 1 hour of mixing and agitation with the impeller 3C, the sludge consisting mainly of solids is transferred to the sedimentation tank 3.
It is discharged from the discharge port 3f provided at the bottom of the.

を使用することができる。The sludge taken out from the discharge port 3f is then sent to the dehydrator 4.
The separated water is then dehydrated to form a cake, and the separated water is combined with the supernatant liquid in the settling tank 3 and discarded as described above. The dehydrated cake has most of the water removed and is either transported directly to a landfill or incinerated in a separate incinerator. As the dehydrator 4, a centrifugal dehydrator (screw decanter), a pressure dehydrator (roll press), or a vacuum dehydrator can be used.

処理することができる。According to the jellyfish dehydration and solidification treatment method and jellyfish dehydration and solidification treatment apparatus of the present invention, a flocculant is added to the turbid water after crushing the jellyfish into small pieces, and the sludge that has been concentrated, flocculated, and precipitated is dehydrated. Since the jellyfish is then disposed of or incinerated, the solid content of the jellyfish can be separated from the water and only the solid content reduced in volume and weight can be disposed of.
