Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water treatment apparatus which can be moved and transported, and more particularly to a container type sewage which can be easily installed or exchanged and collected near a sewage source without special construction. It relates to a processing device.

[0002]

2. Description of the Related Art Conventionally, an activated sludge method is known as a typical method of sewage treatment. This method has a BOD of about 300
If the amount is less than mg / l, a large amount of sewage can be treated, so that it is mainly used in large facilities such as water purification plants. However, even if it says water treatment, it is miscellaneous such as treatment of river water marsh, seawater, domestic wastewater or industrial wastewater, and it is necessary to devise a treatment method which is considered to be optimal depending on the object and individually cope with it.

Under such circumstances, a sewage treatment method using microorganisms adhered to a biological carrier is capable of denitrification by anaerobic bacteria and the like, which are compact and highly efficient in reducing BOD.
The activated sludge method has advantages such as removal of fats and oils that could not be removed by the activated sludge method. Under such circumstances, demands for small-scale equipment and test equipment are increasing, but no mobile wastewater treatment equipment is known.

[0004]

Accordingly, a first object of the present invention is to provide a movable and transportable container-type sewage treatment apparatus which can be easily installed without any special construction. It is in. A second object of the present invention is to provide a small, easily movable and transportable container-type sewage treatment apparatus suitable for experimental use in accordance with the type of sewage. Further, a third object of the present invention is to provide a container-type sewage treatment apparatus which is suitable for wastewater treatment from a food store or the like and can be used immediately and easily even in an urban area.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to provide a water treatment apparatus having a biological carrier in one or more containers having a water inlet and a drain, and for operating the water treatment apparatus. This has been achieved by a container-type sewage treatment apparatus characterized by comprising a power unit and a control unit.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The wastewater treatment apparatus of the present invention is compact,
In order to achieve high efficiency, a treatment tank having a biological carrier is essential. In addition, a container is always provided with a pair of water inlets and drains, and when the entire processing apparatus is composed of, for example, two container-type apparatuses, the drains of the first container and the inlets of the second container are provided. The water outlet is connected. Of course, the entire apparatus may be stored in one container, or it may be designed to connect three or more container apparatuses. A water suction means for sucking sewage from a sewage source is appropriately designed and connected to the source water inlet of the container, and a bellows-like means which is easily deformed is preferable.

[0007] The size of the container may be an optimal one according to the required water treatment capacity. However, in consideration of the nationwide road conditions, the width is 2.2 m, the length is 6 m, and the height is 2.2.
It is preferable to store in a container that can be loaded on a 4-ton truck within m. However, it is not necessary to limit to this size. For example, when installing in a small-scale food store or the like, a housing of an appropriate size can be designed. Therefore, the concept of the container in the present invention is not limited to the container of the existing standard.

[0008] The container type sewage treatment apparatus of the present invention is a water supply pump for pumping sewage, a fixed quantity pump for quantitatively flowing treated water, a blower for aerating the sewage treatment tank, or a microfilter device. And a power unit for operating the reverse osmosis device. This power unit is an electric power unit that normally functions by receiving power supply. The container-type sewage treatment apparatus of the present invention is preferably provided with a power generator for supplying the above-mentioned electric power, from the viewpoint of ensuring mobility.

The configuration of a sewage treatment apparatus having a biological carrier according to the present invention, the size of a treatment tank, and the like depend on the type of sewage to be treated, the degree of contamination, and target values of check items required for the treated water. May be determined as appropriate. In the simplest case, it is a case where it comprises only one treatment tank provided with an aeration device and provided with a biological carrier. Depending on the situation, a sedimentation tank is provided in the subsequent stage, or a biological carrier is provided in the preceding stage. May be provided. When the BOD in the sewage is high, a reaction tank for sprinkling sewage onto a biological carrier suspended in the air between a pre-stage of a settling tank or between the pretreatment tank and a processing tank having an aeration device and a biological carrier. (Bioreactor) can be further provided.

Further, if a microfilter device is disposed downstream of the settling tank, the treated water can be used as clean water. In the case of seawater, a reverse osmosis device can be disposed downstream of the microfilter device. For example, it is possible to obtain purified water from desalted seawater. The control device is for operating the sewage treatment device in which these are combined under a certain condition, and a warning device may be added as needed.

[0011]

The container type sewage treatment apparatus of the present invention is transportable and equipped with all necessary equipment for sewage treatment in advance. Can be used. Since small ones can be prepared as appropriate, it is possible to quickly and surely respond to needs in urban areas. In addition, by providing a power generation device, mobility can be further enhanced, and it is particularly effective in securing middle water and clean water during a disaster.

EXAMPLES The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the present invention is limited thereto.
FIG. 1 is a conceptual side view of a container-type sewage treatment apparatus 1 of the present invention mounted on a truck. In the case of the present embodiment, as shown in the figure, the water treatment unit having a biological carrier is composed of a pretreatment tank, a bioreactor, an aeration tank having a biological carrier (BM), and a sedimentation tank. In addition, in the sedimentation tank,
Usually no biological carrier is provided.

FIG. 2 is a conceptual plan view of the container type sewage treatment apparatus of FIG. As is clear from this figure, in the case of this example, a blower is provided alongside the generator, and the pretreatment tank has a two-stage structure, and a treatment system having a biological carrier and an aeration device. There are three tanks. Furthermore,
A pump for watering the bioreactor is housed in a pump room adjacent to the bioreactor together with other pumps such as a water supply pump and a constant flow pump.

In the case where waste water does not flow constantly as in the case of waste liquid, a waste liquid receiving tank is required. Usually, this tank is provided separately from the apparatus of the present invention, and the wastewater retained here is pumped up and treated by the apparatus of the present invention. However, a waste liquid receiving tank may be provided as a part of the apparatus of the present invention. That is natural. FIG. 3 is a conceptual diagram showing an example of a processing step by the apparatus of the present invention when a waste liquid receiving tank is provided.
