Description

Ballast water clean-up device and load the boats and ships of this device

(1) technical field

The present invention relates to usually being stored in the ballast water clean-up device that ballast water in the boats and ships purifies usefulness.

(2) background technology

In general, in boats and ships such as oil oil tanker, cargo ship, oil and other items is transported to importer, after relevant goods is unloaded at the harbour, the seawater of same weight is stored in the in board storage bin.This seawater is stored in board, thereby be that the situation of unstability produces because lighten under sail in the back ship that will prevent from advance to unload.That is, because if the ship weight out of reach just can not navigate by water to a certain degree.

The seawater that this realization boats and ships stationarity is used (perhaps fresh water also can) is called ballast water.Foregoing goods importer can be described as so-called ballast water exporting country.

On the other hand, store the boats and ships that ballast water is arranged, to navigation such as goods exporting countries, ballast water is discharged in the coastal waters of this exporting country from importer.Therefore, exporting country of goods etc. can be described as so-called ballast water importer.

, ballast water often contains the special pernicious germ that survives in the ballast water exporting country coastal waters, bacterium etc.For example, known in the coastal waters of Japan, surviving be called the planktonic germ of red tide.Therefore, when the Japan as exporting country is transported to its other country with ballast water, can reckon with a large amount of planktonic situations of red tides that take place in its other country coastal waters.And, malignant bacteria such as cholera bacteria can occur and take place to wait hydrobiont to carry out the problem of International Migration by ballast water unusually in its other country.

Therefore, be used to limit and manage the ballast water of boats and ships and sedimentary international treaties (below, abbreviate the ballace treaty as), passed through by 74 participating nations in Britain (London) on February 13rd, 2004.In this treaty, the effluent standard when discharging ballast water as the coastal waters in ballast water importer has been formulated the biological standard of so-called ballast water draining.As not satisfying this standard, then the draining of ballast water just can be refused by the importer of ballast water, promptly excludes ballast water.

As the biological standard of ballast water draining, be meant that specifically germs such as animals and plants plankton are at " 10/m ³" below.And, when bacterium is cholera bacteria below " 1/100ml ", when being coliform below " 250/100ml ", when being big enterococcus below " 100/100ml ".

Processing about above such ballast water, propose a kind ofly before storing ballast water in board, to purify, the ballast water that will purify loads in board ballast water purification techniques (for example, with reference to the open communique 2004-25040 communique of Japan's special permission) again.By utilizing such ballast water purification techniques, thereby for example navigate by water ballast water importer, after this importer approaches, when discharging the ballast water of storing in port, can discharge the ballast water that has purified at freighter.

In addition, as ballast water purification method in the past, propose a kind of ballast water clean-up device that heat treatment is the master that is configured in board, ballast water in the ship is carried out the ballast water purification techniques (for example, with reference to the open communique 2004-284481 communique of Japan's special permission) of circularly purifying.In addition, as ballast water clean-up device in the ship, a kind of ballast water clean-up device (for example, with reference to the open communique 4-322788 communique of Japan's special permission) that comprises the device of bactericidal agent adding apparatus that bactericidal agent can be added in the ballast water and the ballast water that air can be injected draining is proposed.

In the mode of utilizing aforesaid ballast water purification techniques, there is following problem.

Even 1 ballast water after will purifying loads in board, but the not thorough and remaining germ of sterilization propagation under sail often.At this moment, just ballast water can not be discharged in the port of importer etc.

In general, even utilize clean-up devices such as filtering installation, sterilizing unit to purify ballast water, but because the germ, the bacterium that contain in the ballast water exist in a large number, perhaps exist in these germs or the bacterium to clean-up device have resistivity germ, bacterium etc., so the possibility of remaining germ, bacterium is very high in the in board ballast water of loading.

2, under sail, there are germ, bacterium from air, to sneak into to store possibility in the ballast water in the in board storage bin.Especially in ballast water exporting country coastal waters, marine germ etc. becomes the spittle and swims in gas phase, therefore, exists and sneaks into the possibility in the storage bin in the ship.

Therefore, after ballast water after the purification loaded in board, the germ of sneaking into from air, bacterium can breed under sail, and situation appears ballast water can not being discharged in the port of importer etc. in the result.

(3) summary of the invention

What therefore, the object of the present invention is to provide that a kind of germ that will be contained and bacterium can satisfy standard value in the time will being stored in ballast water in the boats and ships and discharging, in the ballast water can realize the ballast water clean-up device that ballast water purifies.
