Translated fromJapanese

本発明は、船舶や海上から含油廃水を回収し浄化処理する含油廃水処理船に関する。  The present invention relates to an oil-containing wastewater treatment ship that collects and purifies oil-containing wastewater from a ship or the sea.

船舶の船底には、エンジン等からの油を含有したビルジ水、水バラスト(錘)、タンク洗浄水等が含油廃水として溜まる。従来、この含油廃水は回収後、陸上の廃油処理施設まで移送され、そこで油水分離処理が行われている。
しかしながら、このように陸上に設置された処理施設まで含油廃水を移送するのは、作業に掛かるコストと時間とを多大に要するため効率的ではなかった。
On the bottom of the ship, bilge water containing oil from an engine or the like, water ballast (weight), tank washing water, and the like collect as oil-containing wastewater. Conventionally, this oil-containing wastewater is collected and transferred to a land-based waste oil treatment facility where oil-water separation treatment is performed.
However, it is not efficient to transfer the oil-containing wastewater to the treatment facility installed on land in this way because it requires a lot of work cost and time.

このような問題に対し、特許文献1(特許第3428898号公報)には、船舶内に設置され、その船舶の船底に溜まる含油廃水(油含有ビルジ水)の油分と水分とを分離して回収する船舶ビルジ用浮遊油回収装置が開示されている。この浮遊油回収装置によれば、船舶内のビルジタンク等に溜まった含油廃水の水面に浮遊する浮遊油を、ビルジポンプによって吸引して油水分離槽に収容し、ここで油分と水分とに分離し、油分は廃油タンクに収容し、水分は船舶内のビルジタンク等に帰還するようになされる。
特許第3428898号公報
In order to solve such a problem, Patent Document 1 (Japanese Patent No. 3428898) discloses an oil-containing wastewater (oil-containing bilge water) that is installed in a ship and accumulates at the bottom of the ship, and separates and collects the oil and water. A floating oil recovery device for ship bilge is disclosed. According to this floating oil recovery device, floating oil floating on the surface of oil-containing wastewater collected in a bilge tank or the like in a ship is sucked by a bilge pump and stored in an oil / water separation tank, where it is separated into oil and water, Oil is stored in a waste oil tank, and moisture is returned to a bilge tank or the like in the ship.
Japanese Patent No. 3428898

特許文献1に開示された浮遊油回収装置によれば、含油廃水を生じる船舶内にその装置を設置することにより、含油廃水に浮遊する油分を取り除くことができ、ビルジ廃油処理のメンテナンスが容易となる。
しかしながら、そのような浮遊油回収装置は一般には未だ普及しておらず、殆どの船舶においては、前記したように含油廃水は地上の処理施設まで移送回収後、その処理施設において廃油水分離処理が行われている。

Has been done.

また、船舶の座礁、沈没等の海難事故により船舶から海上に流出した多量の燃料油、積荷油等に対しては、特許文献1に示される浮遊油回収装置程度の処理能力では対処できず、回収船による油水回収後、地上における処理施設において廃油水分離処理が行われている。
即ち、現況にあっては、殆どの船舶での含油廃水や、海難事故等により海上に流出した油に対しては、油回収船等による回収後、その油水分離処理等は地上の廃油処理施設で行われており、その結果、作業に掛かるコストと時間とを多大に要し、効率的な含油廃水処理環境が提供されているとは云えない。
Also, a large amount of fuel oil, cargo oil, etc. that have flowed out of the ship due to marine accidents such as ship landing, sinking, etc. cannot be handled with the processing capacity of the floating oil recovery device shown in Patent Document 1, After oil and water recovery by the recovery vessel, waste oil and water separation processing is performed at a treatment facility on the ground.
In other words, in the present situation, oil-containing wastewater in most ships and oil that has flowed out to the sea due to maritime accidents, etc. are recovered by oil recovery vessels, etc., and then the oil-water separation processing is performed on the ground waste oil treatment facility. As a result, the cost and time required for work are greatly required, and it cannot be said that an efficient oil-containing wastewater treatment environment is provided.

The purified wastewater storage tank 16 is provided with an oil detector (oil content inspection means) 50 for measuring the concentration of oil contained in the purified waste water to be stored (oil content rate). In other words, it is possible to determine on the spot whether the purified wastewater can be returned to the sea. When the oil content of the purified wastewater in the purifiedwastewater storage tank 16 is within a predetermined value in theoil detector 50, the purified wastewater is discharged from thedischarge line 35 to the sea.
On the other hand, when the oil concentration is higher than a predetermined value (reference value), the oil content is further removed by the granular activatedcarbon cartridge filter 51 as filtering means, and the purified seawater is re-contained in the purified wastewater storage tank 16. Then, after the oil concentration is within the predetermined value, it is discharged to the sea.

また、廃油収容タンク12に回収された廃油のうち、タンク底部に溜まったスラッジやゴミは回収ライン40を介して陸上のタンクローリー201等に送出され、その他の廃油は回収ライン41を介して陸上の他のタンクローリー202等に送出されるように構成されている。尚、回収ライン40、41は夫々、図示しないポンプ等を備え、そのポンプにより廃油が送出される。  Of the waste oil collected in the wasteoil storage tank 12, sludge and dust collected at the bottom of the tank are sent to theland tank truck 201 etc. via thecollection line 40, and other waste oil is sent to the land via thecollection line 41. It is configured to be sent out to anothertank lorry 202 or the like. Each of the collection lines 40 and 41 includes a pump (not shown) and the like, and waste oil is sent out by the pump.

尚、前記したパイプ23、24、26、27、30、31、33、34と、それらパイプを通じて処理廃水を送出させるための図示しないポンプ等により流水路形成手段が構成されている。  The above-describedpipes 23, 24, 26, 27, 30, 31, 33, 34, and a pump (not shown) for sending treatment wastewater through these pipes constitute a water flow path forming means.

続いて、このように構成された廃油処理機構10を備えた含油廃水処理船100が、例えば他の船舶200から含油廃水を回収し処理する場合の工程について図3、図4に基づいて説明する。
図3は、廃油処理機構10における廃油処理工程を説明するため、その構造をより模式的に示した図である。図4は、廃油処理機構10における処理工程の流れを示すフロー図である。
Subsequently, a process in a case where the oil-containingwastewater treatment ship 100 including the wasteoil treatment mechanism 10 configured as described above collects and treats oil-containing wastewater from anothership 200 will be described with reference to FIGS. 3 and 4. .
FIG. 3 is a diagram schematically showing the structure of the waste oil treatment process in the wasteoil treatment mechanism 10 in order to explain it. FIG. 4 is a flowchart showing the flow of processing steps in the wasteoil processing mechanism 10.

先ず、含油廃水処理船100は、回収ライン20を介して船舶200から含油廃水を回収し、原水収容タンク11に収容する(図4のステップS1)。
ここで、原水収容タンク11に収容された含油廃水(原水)のうち、上層部に自然分離浮上した油分はスキマー装置36により捕集され、廃油収容タンク12に回収される(図4のステップS2)。
First, the oil-containingwastewater treatment ship 100 collects oil-containing wastewater from theship 200 via therecovery line 20 and stores it in the raw water storage tank 11 (step S1 in FIG. 4).
Here, of the oil-containing waste water (raw water) stored in the rawwater storage tank 11, the oil that naturally separated and floated on the upper layer is collected by theskimmer device 36 and collected in the waste oil storage tank 12 (step S2 in FIG. 4). ).

また、原水収容タンク11に収容された含油廃水のうち、下層部の含油廃水は、パイプ23を介して油水分離器22に送出され、油分と含油水分(処理廃水)とに分離される(図4のステップS3)。
そして、油水分離器22により分離された油分は、廃油収容タンク12に収容され、一方、前記油分が分離された処理廃水(含油水分)は、フィルタボックス25により廃水内に残存する油分が低減される(図4のステップS4)。
フィルタボックス25により油分が低減された処理廃水は、先ず処理タンク14に収容される。そして、処理タンク14に収容された処理廃水に対し、残存する油分をさらに低減するため、サンドフィルタ29によるフィルタリング処理がなされる(図4のステップS5)。
Of the oil-containing wastewater stored in the rawwater storage tank 11, the oil-containing wastewater in the lower layer is sent to the oil-water separator 22 via thepipe 23 and separated into oil and oil-containing water (treated wastewater) (FIG. 4 step S3).
The oil separated by the oil /water separator 22 is stored in the wasteoil storage tank 12, while the treated waste water (oil-containing moisture) from which the oil has been separated is reduced in the oil remaining in the waste water by thefilter box 25. (Step S4 in FIG. 4).
The treated wastewater whose oil content has been reduced by thefilter box 25 is first accommodated in thetreatment tank 14. Then, a filtering process by thesand filter 29 is performed on the processing wastewater stored in theprocessing tank 14 in order to further reduce the remaining oil (step S5 in FIG. 4).

サンドフィルタ29によりさらに油分が低減された処理廃水は、処理タンク15に収容された後、さらにカートリッジフィルタ32によるフィルタリング処理がなされ、そこで殆どの油分が除去される(図4のステップS6)。
そして、カートリッジフィルタ32によりフィルタリング処理された廃水は、浄化済廃水として浄化済廃水収容タンク16に収容され、そこで油検出器50により水質検査が行われる(図4のステップS7)。
The treated wastewater whose oil content has been further reduced by thesand filter 29 is stored in thetreatment tank 15 and further filtered by thecartridge filter 32, where most of the oil content is removed (step S6 in FIG. 4).
The wastewater filtered by thecartridge filter 32 is stored in the purifiedwastewater storage tank 16 as purified wastewater, and a water quality test is performed by theoil detector 50 there (step S7 in FIG. 4).

この検査の結果、浄化済廃水の油分濃度(油分含有率)が所定値(基準値)内であれば(図4のステップS8)、その浄化済廃水は海上に放流される(図4のステップS9)。
一方、油分濃度が所定値より高ければ、再度、所定値内の油分濃度となるまで、粒状活性炭カートリッジフィルタ51によりフィルタリング処理がなされ、所定値内の油分濃度となった場合に、その浄化済廃水は海上に放流される(図4のステップS6)。
尚、廃油収容タンク12内に回収された廃油のうち、タンク底部に溜まったスラッジやゴミは、回収ライン40を介して陸上のタンクローリー201等に送出され、その他の廃油は回収ライン41を介して陸上の他のタンクローリー202等に送出される。
As a result of this inspection, if the oil concentration (oil content) of the purified wastewater is within a predetermined value (reference value) (step S8 in FIG. 4), the purified wastewater is discharged to the sea (step in FIG. 4). S9).
On the other hand, if the oil concentration is higher than the predetermined value, filtering processing is performed by the granular activatedcarbon cartridge filter 51 again until the oil concentration becomes within the predetermined value. Is discharged to the sea (step S6 in FIG. 4).
Of the waste oil collected in the wasteoil storage tank 12, sludge and dust collected at the bottom of the tank are sent to theonshore tank truck 201 etc. via therecovery line 40, and other waste oil is sent via therecovery line 41. It is sent toother tank trucks 202 on the land.

以上のように本実施の形態によれば、航行可能な船体の上部及び内部に、多量の含油廃水を処理可能な廃油処理機構を備えているため、他の船舶で生じた含油廃水や海難事故等により海上に流出した含油水を回収し、その場で油水分離処理を行い、処理廃水を浄化し、浄化済廃水として海上に還元することができる。
即ち、従来は、一旦、回収船等により含油廃水を回収し陸上の廃油処理施設で処理を行っていた作業を回収現場で行うことができるため、掛かるコストや作業時間が低減され、効率的な含油廃水処理を行うことができる。
また、海上で移動作業を行うため、既存する陸上の廃油処理施設に比べ、廃水を運搬するための作業車両の作業エリア等の土地確保が不要であり、小さい設置面積で廃油処理機構を形成することができる。これにより、廃油処理機構の設置に要するコストの面でも低減することができる。
As described above, according to the present embodiment, since the waste oil treatment mechanism capable of treating a large amount of oil-containing wastewater is provided in the upper and inside of the navigable hull, oil-containing wastewater and maritime accidents that have occurred in other ships It is possible to collect oil-containing water that has flowed out to the sea by means of the above, perform oil-water separation treatment on the spot, purify the treated wastewater, and return it to the sea as purified wastewater.
In other words, in the past, once the oil-containing wastewater was recovered by a recovery ship or the like and processed at the waste oil treatment facility on land, it can be performed at the recovery site. Oil-containing wastewater treatment can be performed.
In addition, since the work is carried out at sea, it is not necessary to secure land such as the work area of the work vehicle for transporting waste water compared to existing land waste oil treatment facilities, and a waste oil treatment mechanism is formed with a small installation area. be able to. Thereby, the cost required for installing the waste oil treatment mechanism can also be reduced.

尚、前記実施の形態においては、他の船舶や海上から含油廃水を回収する回収手段としてパイプや図示しないポンプ等からなる回収ライン20により、船舶等から直接、含油廃水を回収する例を図示等により示したが、他の回収手段として、図示しない自走式回収船を用いて含油廃水を回収し、含油廃水処理船100に持ち込むようにしてもよい。  In the above-described embodiment, an example in which oil-containing wastewater is directly recovered from a ship or the like by arecovery line 20 including a pipe or a pump (not shown) as a recovery means for recovering oil-containing wastewater from another ship or the sea is illustrated. However, as another recovery means, oil-containing wastewater may be recovered by using a self-propelled recovery ship (not shown) and brought into the oil-containingwastewater treatment ship 100.

本発明は、他の船舶で生じた含油廃水や、海難事故等により海上に流出した含油廃水を回収し、浄化処理する含油廃水処理船に関し、産業廃棄物処理業界において好適に用いることができる。  The present invention relates to an oil-containing wastewater treatment ship that collects and purifies oil-containing wastewater that has flowed out of the sea due to a marine accident or the like, and can be suitably used in the industrial waste treatment industry.
