Since the (electrolyte) is mixed with the manure and the seawater is introduced into the manure tank 20 in the same way that the electrolytic treatment for manure is made efficiently, a detailed description of the known technique is omitted.

As manure mixed with sea water flows into the electrolytic treatment tank 30 as described above, electrolytic treatment is performed on the manure liquid from the inside of the electrolytic treatment tank 30. The manure liquid does not contain foreign substances and the manure liquid and seawater. Since only the inflow is made, the electrolytic treatment for manure is made efficiently.

The treated water electrolytically treated in the electrolytic treatment tank 30 is transferred to the discharge tank 40, as shown in FIG. 8, and is contained in the water level sensor 41 installed in the discharge tank 40. By operating the discharge pump 43 to transfer the treated water contained in the discharge tank 40 to the filtration filter 50.

The treated water flowing into the filtration filter 50 includes debris of small particles, such as suspended solids. The debris enters the inlet 52 as shown in FIG. 5 and subsequently flows into the filter bag 56. Since the filter bag 56 is made in the form of a bag as fabric paper, small debris in the treated water is caught in the filter bag 56 and the liquid leaks out of the filter bag 56.

The liquid in the treated water leaked out of the several filter bag 56 is discharged to the outside while being discharged to the outside through the discharge port 53 installed on the lower side of the cylinder 54, or to be contained in the storage tank 60 do.

The treated water discharged to the outside of the cylinder 54 of the filtration filter 50 from above is filtered out to small debris and is discharged as it is in the general sea. In step 50, the treated water filtered again is stored in the storage tank 60 without being discharged into the sea, and then discharged into the far sea corresponding to the treatment standard of the discharged water.

When the manure treatment apparatus 1 for ships according to the present invention is used for a long time, the electrolytic treatment tank 30 and the filtration filter 50 are trapped, resulting in deterioration of the treatment efficiency of the manure and thus the electrolytic treatment tank 30 and the filtration filter ( 50), the washing process will be described with reference to FIG.

Open and close the corresponding valve so that the seawater moves only to the pipeline flowing in the direction of "D", and close the other pipeline.

When the seawater is introduced into the seawater inlet pipe 4 in this way, a separate pump (not shown) installed in the vessel is used to introduce the seawater at high pressure, and the high pressure introduced into the electrolytic treatment tank 30 as in "A" first. Dropping the residue stuck in the interior of the electrolytic treatment tank 30 by the sea water of the discharged to the conduit connected to the manure tank 20, such as "C" to remove the residue from the electrolytic treatment tank 30 to the manure tank (20) Will flow into.

As the sea water flows into the manure tank 20 while the seawater passes through the interior of the electrolytic treatment tank 30 as described above, the seawater inflow pipe through which the seawater passes at high pressure as well as the inside of the electrolytic treatment tank 30 is washed (4). ) "A" direction of the pipe line-electrolytic treatment tank 30- "C" direction of the pipe line-the manure tank 20 is to be washed.

At this time, the internal volume of the electrolytic treatment tank 30 and the manure tank 20 is designed to vary in size depending on the vessel in which the marine manure treatment device 1 is installed, the applicant of the present invention is the Since the internal volume of the manure tank 20 is made larger than the internal volume by about 20 times, the amount of seawater introduced to clean the electrolytic treatment tank 30 does not exceed the internal volume of the manure tank 20.

Next, a description will be given when the filtration filter 50 is backwashed. In this case, as shown in FIGS. 5 and 8, the seawater introduced at a high pressure through the seawater inlet pipe 4 is connected to the piping line in the “A, B” direction. Through the filtration filter 50 is introduced into the inside.

The filtration filter 50 is introduced into the lower back washing line (L1) of the cylinder 54 as shown in Figure 5, the sea water is introduced at a high pressure, such as "B", the bag support 55 in the interior of the cylinder 54 As the inner space of the cylinder 54 is partitioned, several filter bags 56 are provided below the bag holder 55, so that the seawater flowing in at high pressure can pass through the filter bag 56 made of fabric paper. do.

As the above-mentioned high pressure seawater passes through the filter bag 56 made of fabric paper, the debris stuck on the inner surface of the filter bag 56 is separated from the inner surface of the filter bag 56 while being backwashed on the upper side of the cylinder 54. It is to be discharged to the outside through the line (L2) as shown in "D" of FIG.

In addition, FIG. 7 shows a case where two filtration filters 50 are provided. In this case, the treated water contained in the discharge tank 40 through the discharge pump 43 passes through the two filtration filters 50 in two steps. As a result, the wastewater passing through the two filtration filters 50 may be discharged to the outside in a cleaner state.

When two filtration filters 50 are connected in series as described above, the treated water is immediately discharged to the outside as usual without passing through the two filtration filters 50, or two filtration filters 50 as necessary. 7), the "E" valve installed in the discharge pipe 40b in which the discharge pump 43 is installed, as shown in FIGS.
