本発明は、くらげ等の海水取水口捕捉物の処理

製鉄所あるいは発電所などの大量の海水を利用

ような臭気が発生するとともに、その投棄箇所か
ら汚水が流出するという不都合があつた。 In facilities that use large amounts of seawater, such as steel mills or power plants, floating marine organisms such as jellyfish and seaweed are trapped on the screens at the seawater intake.
It was necessary to deal with these. In particular, jellyfish breed abnormally in the summer, and 1
Dozens of tons are captured every day. Traditionally, jellyfish were left in a hole dug in the ground, but
In the summer, when the amount of wastewater is large, there is an inconvenience in that the smell of rotting fish is emitted and sewage flows out from the dumping point.
本発明はこのような不都合を改善することを目

(B) An oxidation treatment means for purifying the liquid obtained from the compression dehydration means.

えば、ポンプの羽根にカツター機能を持たせたも
のやインラインミキサなどで十分である。 Hereinafter, embodiments of the present invention will be described in more detail with reference to FIG. Jellyfish 10 (hereinafter referred to as jellyfish, although other floating objects such as seaweed are also included) captured in the seawater intake are first placed in a dewatering basket 12 to drain the seawater, and then sent to a crusher 14. After turning into a slurry, it is sent to a compressor dehydrator 16. After capturing the jellyfish, it is possible to directly press and dehydrate them, but in order to increase the dehydration efficiency, a crushing method such as crushing them into a slurry or cutting them into small pieces is required prior to this process. It is preferable. 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. Since jellyfish are soft, there is no need for any special crushing means; for example, a pump blade with a cutter function or an in-line mixer will suffice.
圧搾脱水機１６としては、フイルタープレスな
ど圧搾式のものであればいずれも用いられ、ベル
トプレス型なども採用できる。 As the compressing dehydrator 16, any compressing type such as a filter press can be used, and a belt press type can also be used.

後、焼却その他の適当な処理が施される。 The liquid from the dehydrator 16 contains a large amount of organic components, and is discharged after being treated by a purification treatment means to a value that satisfies discharge standards. The flow sheet of FIG. 1 shows a case where the organic matter decomposition treatment of the dehydrated liquid is carried out by chemical oxidation treatment using sodium hypochlorite. First, the liquid is sent to oxidation treatment tank 1.
8, where it is oxidized with sodium hypochlorite while keeping the pH near neutral. The oxidized liquid is sent to the coagulation treatment tank 20, and the SS
is removed. In the flocculation treatment tank 20, polyaluminum chloride (PAC), a polymer flocculant, or a flocculation aid is added, and a known flocculation separation device can be used for flocculation separation. After dehydration, the aggregated solids are incinerated or otherwise subjected to appropriate treatment.
凝集処理槽２０からの清澄液は、脱塩素槽２２
に送られて、残留塩素除去処理がなされている。
この処理は、ニツケル触媒を用いて簡単に行なえ
るが、その他の公知の処理方法も採用できる。 The clarified liquid from the flocculation treatment tank 20 is transferred to the dechlorination tank 22.
The water is then sent to the factory to be treated to remove residual chlorine.
This treatment can be easily carried out using a nickel catalyst, but other known treatment methods can also be employed.
残留塩素が除去された液は、ついで活性炭処理
槽２４に送られ、さらに仕上げ処理がなされる。
活性炭処理は、液に粉末活性炭を添加混合し、液

ある。 The liquid from which residual chlorine has been removed is then sent to the activated carbon treatment tank 24, where it is further subjected to finishing treatment.
Activated carbon treatment involves adding and mixing powdered activated carbon to the liquid, allowing the COD components in the liquid to be adsorbed and removed by the activated carbon.
This is done by separating the activated carbon, and the treatment liquid is discharged. Activated carbon adsorption treatment can also be carried out by a method such as passing liquid through a column filled with powdered activated carbon.
なお、このように仕上処理として活性炭による
吸着処理を行なうときは、この処理により残留塩

省略することもできる。しかしながら、活性炭の
負荷軽減のためには、上記のフローによることが
好ましい。 Note that when adsorption treatment using activated carbon is performed as a finishing treatment in this manner, residual chlorine can also be removed by this treatment, so the dechlorination tank 22 can be omitted. However, in order to reduce the load on activated carbon, it is preferable to follow the above flow.
本発明における酸化処理手段としては、活性汚
泥を用いる生物学的手段を用いることもできる。
この場合、近くに活性汚泥処理施設があるとき
は、それを利用することも可能である。 As the oxidation treatment means in the present invention, biological means using activated sludge can also be used.
In this case, if there is an activated sludge treatment facility nearby, it is also possible to use it.
本発明のくらげの処理装置によれば、海水取水

ことができ、しかも、二次公害を引きおこすこと
もない。 According to the jellyfish processing device of the present invention, a large amount of jellyfish caught in a seawater intake can be efficiently processed without causing secondary pollution.
