出するという不都合があった。At facilities that use large amounts of seawater, such as steel mills and power plants, floating marine organisms such as jellyfish and seaweed are trapped on the screens at the seawater intake, and these must be disposed of. Jellyfish in particular proliferate abnormally in the summer, and tens of tons of jellyfish are captured each day by screens at water intakes. Traditionally, jellyfish were left as waste in holes dug in the ground, but in the summer, when there are many leaves, a smell similar to rotting fish is emitted, and the place where the jellyfish is dumped smells. There was the inconvenience of sewage flowing out.
本発明はこのような不都合を改善することを目的とした

0 (hereinafter referred to as jellyfish, although other floating substances such as seaweed are included) are first placed in a dehydrator 12 to drain the seawater, then made into a slurry by a crusher 14, and then compressed and dehydrated. Sent to machine 16. After capturing the jellyfish, it is possible to directly compress and dehydrate them, but in order to increase the dehydration efficiency, it is necessary to crush the jellyfish prior to this process, such as by crushing them into a slurry or cutting them into small pieces. It is preferable to provide Furthermore, in order to transfer the jellyfish to a press-dehydrator, it is easier to transfer the jellyfish if it is in the form of a slurry.
なお、くらげは軟らかいので、破砕手段として特別なも
のは必要なく、たとえば、ポンプの羽根にカッター機能

凝集分離は公知の凝集分離装置を用いることができる。The furnace liquid from the dehydrator 16 contains a large amount of organic components, and is discharged after being treated by a purification treatment means at a value that satisfies discharge standards. Sheet 70 in FIG. 1 shows a case where the organic matter decomposition treatment of the dehydrated F liquid is carried out by chemical oxidation treatment using sodium hypochlorite. First, the P solution is sent to the oxidation treatment tank 18, where the pH is maintained near neutrality and oxidation treatment is performed using sodium hypochlorite. The oxidized liquid is sent to the coagulation treatment tank 20, where SS is removed. In the coagulation treatment tank 20, polyaluminum chloride (
PAC) or a polymer flocculant or flocculation aid is added,
A known coagulation separation device can be used for coagulation separation.
