Description

[0001] Apparatus for on-site treating night soil in vessels [

The present invention relates to a sewage treatment apparatus for a ship, and more particularly, to a sewage treatment apparatus for a ship which can be easily installed in a narrow space such as a ship or the like, and has excellent sewage treatment efficiency.

Generally, in order to treat manure or wastewater generated from a ship, a large number of manure storage tanks are made and stored and oxidized. In addition, a method of treating the manure or the wastewater generated by the microorganisms floating in the tank (tank) There is a method of treating wastewater by biologically activated sludge in which air is introduced into a blower so that decomposition and cell synthesis are performed, and an electrolytic treatment method.

The above-mentioned storage-type treatment method requires a large-capacity tank because a large amount of marine wastewater is stored and oxidized, and the amount of sludge is increased, which causes a problem of sludge treatment.

The biological active sludge treatment method is disadvantageous in that since fibrous microorganisms are generated during the treatment process, sludge bulking occurs, and excessive sludge formation causes problems in treating the sludge, However, there is a problem that it is not easy to install in a place where a small space such as a ship or the like should be usefully utilized because the processing apparatus becomes large for complete processing.

The electrolytic treatment method comprises the steps of crushing manure or the like, passing the manure (sewage) and seawater through the electrode plates formed at narrow intervals between the electrodes, and decomposing and oxidizing the organic material by the hypochlorous acid produced by electrolysis of seawater However, it is not easy to break down, and the corrosion of the structure is easy due to the strong oxidizing power of the generated hypochlorous acid (HClO ₃ ) generated when electrolyzing a large amount of seawater, and the treatment water contains hypochlorous acid And may become a secondary source of pollution.

In order to solve the above problems, the ship wastewater treatment apparatus proposed in the Utility Model Registration No. 219789 has a compact and compact structure suitable for a special environment of a ship, has a good sewage treatment capacity, and is installed in a narrow space Easy to maintain, easy to adapt to load fluctuations and temperature changes of manure and wastewater, and to produce a small amount of surplus sludge.

1 is a schematic view showing a conventional ship wastewater treatment apparatus.

That is, as shown in FIG. 1, the conventional sewage and wastewater treatment apparatus of Utility Model Registration No. 219789, which is a prior art, fixes the irregular shaped contact material 13 in the hollow sewage tank 12 provided with the inlet 11, The aeration tank 14 and the treatment water tank 15 are installed in the center of the inside of the sewage tank and the aerobic tank 14 is disposed at the lower side of the aeration tank 14 16 and a guide plate are installed in a spiral shape to allow the microorganisms to suck the microorganisms efficiently and to sterilize the coliform bacteria of the treated water stored by the ultraviolet lamps 17 provided in the treatment water tank 15, And is automatically discharged to the outside by the discharge pump 19 operated by the water level sensor 18 installed in the treatment water tank 15. [

Conventionally, the conventional wastewater treatment apparatus is designed to sterilize E. coli of the treated water by the ultraviolet lamp 17. However, since the manure of the ship is very turbid and the penetration of ultraviolet rays is difficult, the disinfection effect can not be expected And the sewage and wastewater of the ship are decomposed and treated by various microorganisms attached to the contact material 13 and discharged to the sea automatically by the discharge pump 19. However, 13), the microorganisms desorbed by the excessive proliferation do not satisfy the discharge allowance of the suspended solids (SS), and some microorganisms of the undissolved organic matter are directly discharged to the sea and not subjected to a separate disinfection process There is a problem that marine pollution prevention effect is insignificant.

Conventionally, the biofilm filter medium is used to treat organic matters of ship manure and wastewater, but the volume of the settling tank is increased as the sludge in the treated water is concentrated by sedimentation in gravity sedimentation tank.

2, the purified water stored in the discharge tank 140 may be finally discharged through the third pump 160, and the final discharge of the purified water may be controlled through the third valve 161 And the presence or absence of the third valve 161 is not limited in the present invention.

2, the sewage treatment apparatus according to the present invention may include a plurality of level sensors.

More specifically, the sewage treatment apparatus according to the present invention may include a first level sensor 153a to a fourth level sensor 153d located inside the filter tank unit 130, And a fifth level sensor 154a to a seventh level sensor 154c located inside the discharge tank 140.

The controller may further include a level sensor controller 150 for controlling the first level sensor 153a to the seventh level sensor 154c.

Hereinafter, the operation of the sewage treatment apparatus according to the present invention and the functions of these level sensors will be described.

The sewage treatment apparatus according to the present invention can be automatically treated from inflow of manure and wastewater to treatment water, that is, discharge of purified water. First, the manure and sewage introduced into the sewage tank unit 120 Is uniformly processed by the natural flow through the partition located at the sewage tank part 120 and flows into the filter tank part 130 by the natural flow.

When the water level in the filter tank unit 130 reaches L3 153c, the second pump 137, that is, the suction pump is automatically activated by the water level sensor, And is passed through the filter unit 132 by the suction force. In this process, the filtered water is filtered by the clean water of high quality and is also transferred to the discharge tank unit 140.

At this time, when the water level in the tank reaches L2 (153b), the operation of the suction pump can be stopped.

In addition, when the water level falls to L1 (153a), the water level sensor can operate a separate valve to protect the filter portion, and fresh water can be filled up to the level of L2 (153b).

Accordingly, the present invention may include a fresh water supply unit for introducing the fresh water.

On the other hand, if the water level reaches the high water level L4 (153d), a high water alarm may be sounded, and in this case, the flow of manure and wastewater can be stopped any more.

2, the purified water passing through the filter tank unit 130 is transferred to the discharge tank unit 140, and the purified water introduced into the discharge tank unit 140 flows into the discharge tank unit 140 140, the third pump 160, i.e., the discharge pump, can be automatically controlled.

For example, the discharge pump senses the level from the level sensor L5 (154a) to the level sensor L6 (154b), and can automatically stop and automatically stop.

When the water level of the discharge tank portion 140 reaches the high water level portion L7 (154c), a high water level alarm may be sounded. In this case, the flow of still water can be stopped.

As described above, in general, in order to treat manure or wastewater generated in a ship, a large number of manure storage tanks are made and stored and oxidized, and a storage type treatment method in which a manure of a ship or a tank (tank) There is a wastewater treatment method using a biologically active sludge in which air is blown into a blower so that substrate decomposition and cell synthesis can be performed by microorganisms, and an electrolytic treatment method.

In such a general method, there is a problem that it is not easy to install in a place where a small space, such as a ship, should be usefully used. In addition, not only does it not satisfy the emission allowance of suspended solid (SS) The microorganisms of the substance are directly discharged into the sea, and the disinfection process is not performed, so that the marine pollution prevention effect is insignificant.

However, in the present invention, suspended solids (SS), total nitrogen (T-N), total phosphorus (T-P) and the like in sewage can be effectively treated through a fine hollow fiber membrane having a microvoid size of about 0.04 micrometer.
