Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a sewage purifying and holding system for a ship, and more particularly, to a system and a method for holding a gray water for repairing a fault in a sewage purifying apparatus in a ship to which a clean design regulation is applied, The gray water can be used as it is by the new holding system that can be used to keep the crew members from having inconveniences in the residential life of the crew. Also, the held gray water is collectively transported according to the collecting level of the septic tank, Of course, it is possible to prevent the overload and the deterioration of the function of the wastewater treatment equipment in advance.

Generally, the treated water discharged from the residence of the ship is divided into Black Water and Gray Water.

The above-mentioned black water collectively refers to, for example, feces, urine and the treated water. The gray water is, for example, treated water generated in a sink, a bathtub, a sink, It is collectively referred to as various kinds of scum and miscellaneous.

In ships where the Clean Design regulations, which are strictly regulated by the Norwegian Society for the Classification of Shipping (DNV), do not apply, only Black Water is discharged after sanitary treatment, and Gray Water is discharged. Will be discarded into the ocean without going through a separate sewage treatment system.

However, when the above-mentioned Clean Design regulation is applied, not only black water but also gray water should be discharged through the sewage purifying treatment system for purifying treatment and then circulated after the purifying treatment.

Fig. 1 shows a sewage treatment system in a ship to which Clean Design regulations are applied.

The black water is sucked by the driving of the vacuum suction unit 12 connected to the black water line 10 and is transferred to the septic tank 18 when the waste water treatment equipment 26 is operating normally , And the gray water is also directly conveyed to the septic tank 18 through the gray water line 20.

The black water and the gray water collected by the septic tank 18 as described above are discharged to the ocean through the discharge line 28 after the purification treatment through the waste water purification treatment equipment 26.

However, as shown in FIG. 1, when the operation is stopped due to the failure of the sewage purifier 26, it is impossible to directly discharge the black water and gray water by the clean design regulations as described above, The black water is collected by the septic tank 18 while the repair for the normal operation of the purification treatment equipment 26 is performed and the use of the gray water is stopped or restricted so as not to occur as much as possible, .

In addition, for example, when the possibility of exceeding the collection capacity of the black water and the gray water is predicted to be larger than the collection capacity of the septic tank 18, the use may be stopped or limited so that the gray water no longer occurs, There was a lot of inconvenience. When the capacity of the septic tank 18 is further increased to solve the inconvenience, the problem may be solved somewhat, but the size of the septic tank 18 becomes relatively large, thereby making it difficult to secure the installation space.

This design is intended to solve the problems described in the background art. In order to solve the trouble of the sewage treatment equipment in the ship to which the Clean Design regulation is applied, it is possible to hold the Gray Water It is possible to use the gray water by the new holding system as it is, so that there is no inconvenience in the residence life of the crew, and the gray water held by the holding water is variably transferred according to the collecting level of the septic tank, The object of the present invention is to provide a septic purification and holding processing system for a ship, which can prevent an overload and a deterioration of function of the septic purification apparatus.

In the present invention, there is provided a vacuum cleaner comprising: a vacuum suction unit connected to a black water line; a purifier connected to the vacuum suction unit to collect black water; a gray water line connected to the purifier; A gray water holding tank connected to the gray water line through the holding line; An on-off valve installed on the holding line for opening and closing the gray water to be collected by the gray water holding tank; And a transfer line connected between the gray water holding tank and the septic tank for transferring the gray water held in the gray water holding tank to the septic tank.

Also, in the present invention, there is provided a marine sanitation holding and processing system in which a feeding pump for feeding gray water collected by a gray water holding tank to a transfer line is provided in a transfer line.
