Cleaning solution after use be discharged into it is marine, but largely containing the particles such as dust (pollution particle) in cleaning solution, therefore cannot
It is directly discharged to marine.Therefore, it is separated off from the cleaning solution that washer 117 is discharged using waste water treatment system 100
It is discharged into after the purified treatment of pollution particle marine.Waste water treatment system 100 is illustrated below.
<waste water treatment system>
Then waste water treatment system 100 is illustrated.Waste water treatment system 100 has: retaining them temporarily from washer 117
The reservation tank 10 of the cleaning solution of middle discharge；The wastewater treatment portion 20 of purified treatment is carried out to cleaning solution；And from retain tank 10 to
The supply pump 30 of the supply of wastewater treatment portion 20 cleaning solution.
Herein, the discharge rate (hereinafter referred to as " discharge rate ") per unit time for the cleaning solution being discharged from washer 117
It is changed according to the operational situation of washer 117.Specifically, when EGR rate maximum, the maximum flow of EGR gas, therefore by this
When washer 117 in discharge rate as maximum throughput.
On the other hand, for the supply amount per unit time of the cleaning solution supplied from reservation tank 10 to wastewater treatment portion 20
(hereinafter referred to as " supply amount ") is controlled, so that the supply amount is during entire than the maximum throughput of washer 117

<retaining tank>
Then the composition for retaining tank 10 is described in detail.Fig. 2 is the schematic diagram of waste water treatment system 100.Such as Fig. 2 institute
Show, the reservation tank 10 of present embodiment has can body 11, floating member 12 and suction tube 13.
Can body 11 is the part for retaining cleaning solution.A part of can body 11 is formed by a part of hull 102.Specifically
Say that the bottom of can body 11 is formed by the hull bottom of hull 102 in ground.The hull bottom of hull 102 is in section vertical relative to front-rear direction
There is the curved shape protruded downwards in the view of face.Can body 11 is formed using the hull bottom of such shape.Therefore, according to
Present embodiment can effectively utilize the space near the hull bottom of the shape with deformation.
In addition, can body 11 includes inflow being formed in sidewall portion, flowing into for the cleaning solution being discharged from washer 117
Mouth 14；It is similarly formed outflux 15 in sidewall portion, flowing out for the cleaning solution supplied to wastewater treatment portion 20；And it is formed in
Top, the air scoop 16 that leads to outboard.In addition, being high pressure in washer 117, therefore flowed into the cleaning solution of washer 117
When making pressure reduction in can body 11, generated from cleaning solution it is molten deposit gas, the bubble for including in cleaning solution expands.Institute
The molten air deposited gas and constitute bubble generated is released to outboard by air scoop 16.
Floating member 12 is the portion that relative density is less than cleaning solution, the liquid level for swimming in the cleaning solution that can body 11 is retained
Part.Floating member 12 swims in the liquid level of cleaning solution, therefore even if the amount of cleaning solution changes and makes liquid level upper and lower displacement, drift
Floating component 12 also follows the liquid level and upper and lower displacement.
Suction tube 13 has flexibility, and base end portion is mounted on the outflux 15 of can body 11, and front end portion is mounted on floating
Component 12.Suction tube 13 has suction port 17, the cleaning solution that suction port 17 attracts can body 11 to be retained in front end portion.By inhaling
The cleaning solution for drawing the attraction of mouth 17 is supplied by outflux 15 and supply pump 30 to wastewater treatment portion 20.
In addition, suction port 17 is located at position corresponding to the lower surface of floating member 12 in present embodiment.Therefore, it inhales
Draw mouth 17 to be always positioned near the liquid level of cleaning solution.No matter the water level of cleaning solution as a result, suction port 17 can attract always
Cleaning solution, can be by the cleaning solution supplying attracted to wastewater treatment portion 20.
Herein, the pollution particle for including in cleaning solution be divided into relative density greater than cleaning solution sedimented particle 151 and
Relative density is less than the floating particle 152 of cleaning solution (referring to Fig. 3 etc.).Sedimented particle 151 settles in cleaning solution, floating particle
152 float in cleaning solution.That is, retaining tank 10 will be divided into pollution particle and retaining them temporarily cleaning solution concentration in cleaning solution
The high part part low with the pollution concentration of particle.It should be noted that the ratio of sedimented particle 151 and floating particle 152
It is different using fuel etc. according to used in engine 111.
In present embodiment, it is assumed that the case where pollution particle for including in cleaning solution is largely sedimented particle 151.That is,
In present embodiment, the section below for retaining the cleaning solution that tank 10 is retained is to pollute the highly concentrated part of particle, cleaning solution
Section below other than part be the low part of concentration for polluting particle.In this way, in present embodiment, the position always of suction port 17
Near the liquid level of cleaning solution, therefore pollutes cleaning solution corresponding to the low part of concentration of particle and preferentially supplied to waste water
In reason portion 20.Therefore, the pollution particle that supply includes into the cleaning solution in wastewater treatment portion 20 can be reduced, can reduce and be based on
The load of the purified treatment in wastewater treatment portion 20.
<utilization example>
Then the utilization example of the waste water treatment system of present embodiment 100 and ship 101 is illustrated.Here, ship
101 sail from the 1st port in ECA (Air Pollutants emission control sea area), by ECA outside ocean, the in ECA the 2nd
It enters a port at port.In addition, it is empty that ship 10, which when the 1st port is left the port, retains tank 10,.It should be noted that the ECA is set in close to land
It is the sea area of the discharge of polluter of the strict control comprising NOx near the bank on ground.
Firstly, ship 101 navigates by water in ECA during one section after leaving the port from the 1st port, therefore in order to reduce from starting
The NOx being discharged in machine 111 carries out EGR.Therefore, the discharge rate for the cleaning solution being discharged from washer 117 is more, at this time discharge rate
For maximum throughput.
Later, it will flow into and retain in tank 10 from the cleaning solution that washer 117 is discharged, retain tank 10 and retain cleaning solution.It is another
Aspect carries out purified treatment by the supply cleaning solution of tank 10 is retained in wastewater treatment portion 20, but supplies to wastewater treatment portion 20
Supply amount it is fewer than the maximum throughput of above-mentioned washer 117.Therefore, during ship 101 navigates by water in ECA, retain tank 10
The amount of the cleaning solution retained gradually increases.
Later, ship 101 is driven out to ECA and navigates by water outside ECA.Outside ECA, the emission control of NOx is more relaxed, therefore ship
When oceangoing ship 101 navigates by water outside ECA, stop EGR (at this point, EGR rate is 0%).Therefore, cleaning solution is not discharged from washer 117.Separately
On the one hand, continue to supply cleaning solution in wastewater treatment portion 20.As a result, the amount for retaining the cleaning solution that tank 10 is retained gradually subtracts
