Description

本発明は、内部に流入したバラスト水を濾過して外部へ流出させる筒状のフィルタと、前記フィルタの二次側に設けられ、前記フィルタに向かって逆洗水を噴射する逆洗水噴射ノズルと、前記逆洗水噴射ノズルに向けて逆洗水が流通する逆洗水流通ラインと、前記逆洗水流通ラインに設けられ、前記逆洗水流通ラインを流通する逆洗水を濾過する再生型濾過器と、を備えるバラスト水処理装置に関する。 The present invention includes a tubular filter which flowing out is filtered ballast water flowing therein, provided on the secondary side of the front Symbol filter backwash water injection for injecting backwash water towards the filter A nozzle, a backwash water distribution line through which the backwash water circulates toward the backwash water injection nozzle, and a backwash water distribution line provided in the backwash water distribution line to filter the backwash water flowing through the backwash water distribution line. And a regenerative filter.

また、バラストタンクに貯留されるバラスト水が、前記再生型濾過器を再生するための再生用水として利用されることが好ましい。 Further, the ballast water stored in ballast tanks, are preferably used as the regeneration water for regenerating said regenerative filter.

本発明のバラスト水処理装置の一実施形態を、図面を参照して説明する。図１は、本発明のバラスト水処理装置の一実施形態を示すフロー図である。
図１に示すように、本実施形態のバラスト水処理装置１は、バラスト水濾過装置２と、紫外線リアクタ６１と、清浄水タンク６３と、再生型濾過器７０と、逆洗水供給手段７と、制御部（図示せず）と、を備える。 An embodiment of the ballast water treatment apparatus of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart showing an embodiment of the ballast water treatment apparatus of the present invention.
As shown in FIG. 1, the ballast water treatment apparatus 1 of this embodiment includes a ballast water filtration device 2, ultraviolet reactor 61, and Kiyoshi water tank 63, a regenerative filter 70, a backwash water supply means 7 And a control unit (not shown).

本実施形態は、ラインとして、被処理水導入ラインＬ１と、被処理水排出ラインＬ２と、処理水ラインＬ１１と、貯留処理水排出ラインＬ１２と、逆洗水流通ラインＬ２１と、再生用水ラインＬ２４と、清浄水ラインＬ２５と、再生排水ラインＬ２６と、エア抜きラインＬ３１と、を備える。「ライン」とは、流路、経路、管路等の流体の流通が可能なラインの総称である。
This embodiment forms state as a line, the treated water inlet line L1, the treatment water discharge line L2, the treated water line L11, a reservoir treated water discharge line L12, and backwash water distribution lines L21, reproduction water line L24, clean water line L25, regeneration drainage line L26, and air vent line L31 are provided. “Line” is a general term for lines capable of flowing fluid such as flow paths, paths, and pipelines.
