However, the purification of pond water and river polluted water of the prior art is mainly performed by the method of purification between gravel, but the initial cost of civil engineering work and land is low for the purification effect. The cost was high, construction costs were high, and the water treatment area for polluted water was fixed. In addition, a fountain with a float provided with a sewage purification device as a hydrophilic landscape facility is capable of purifying sewage while moving and has a scenic nature, but has a drawback of low treatment capacity. Was. The invention of the present application is an improvement of a device that can set the size of a purification unit according to the amount of pond water or lakes and marshes proposed by the applicant of the present invention and the degree of contamination, and provides a biological contact oxidation device that does not impair the landscape. It is.

SUMMARY OF THE INVENTION The gist of the present invention is to load a contact oxidizing material into a tank having open front and rear surfaces,
A plurality of tank bodies are detachably connected in the front-rear direction to form a purification unit, and the front and rear end faces of the purification unit are closed, and an inlet for pond water or the like and an outlet for treated water are provided on the wall surfaces, respectively. Pond water or the like is passed through a plurality of tanks loaded with a contact oxidizer to purify polluted water by contact oxidation with microorganisms . Then, the upper end of the tank body may be raised above the water surface, a tread plate may be provided on the upper surface thereof, and the upper part of the purification unit may be a floating pier, which may also serve as a hydrophilic landscape facility.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is constructed as described above, and the number of connected tanks is set according to the amount of water in a pond, lake or marsh to be installed and the degree of contamination, and the tanks are disposed in pond water or the like. Then, when polluted water such as pond water flows in from one end of the purification unit, the polluted substances of the influent water are adsorbed by microorganisms living in the contact oxidizing agent, and are biodegraded, and nitrogen and phosphorus are removed.
From the other end of the purification unit, the treated water is discharged into pond water.
At this time, if the inlet and outlet of the purification unit are provided near the surface of the pond water, the pump power can be reduced. Further, in the purification unit in which the front and rear surfaces of the tank body are opened into the pond water, the contact oxidizing material of each tank body directly comes into contact with the pond water, so that large-capacity pond water or the like with a low degree of pollution can be purified. If a filtration device using a floating filter material is installed in front of the purification unit, the load of polluted water such as highly polluted pond water can be reduced, the clogging of the contact oxidizing material can be prevented, and the purification ability by microorganisms can be maintained. be able to. If a tread is arranged on the upper surface of the tank body and the upper part of the purification unit is a floating pier, it can be used as a hydrophilic landscape facility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, in FIG. 1, reference numeral 1 denotes a tank body having open front and rear wall surfaces. The fibrous or honeycomb contact oxidizing material 2 is loaded.
This contact oxidizing material 2 has an upper edge supported by a hanging rod 3 provided in the front-rear direction where the tank body 1 is opened, and a tension rod 4 is connected to the lower edge thereof, so that the water flowing direction is in the tank 1. Many are hung along. Reference numeral 5 denotes a float, which is provided on both side walls of the tank body 1 as shown in FIG.
The buoyancy has been adjusted so that the upper part is above the water surface. Reference numeral 6 denotes a sludge pit provided at the bottom of the tank body 1.

As shown in FIG. 3, the tank body 1 loaded with the contact oxidizing material 2 comprises a plurality of tank bodies 1... And
Purification units 7 according to the amount of water in the ponds, lakes and marshes, and the degree of contamination.
The purification unit 7 can be moved to a suitable place such as a lake by a float 5 provided in the tank body 1. The front surface and the rear surface of the purification unit 7 are closed by wall surfaces, and an inlet 8 for polluted water such as pond water and an outlet 9 for treated water are provided at a water surface level H above each wall surface. The pond water is circulated at the level, and the power of the pump 10 is reduced. Then, the water from the lake or the like is sent to the inflow port 8 of the purification unit 7 by the pump 10, transferred between the contact oxidizing materials 2, the organic matter is decomposed by microorganisms, and the treated water is taken out from the discharge port 9 at the subsequent stage. is there. Reference numeral 11 denotes a current plate provided before and after the plurality of tank bodies 1.

In a lake with little pollution, the purification unit 7 is constructed by opening the front and rear open surfaces of the tank body 1 to face the water in the water, and detachably connecting the left and right side surfaces of the plurality of tank bodies 1. And
The polluted water may be purified by natural inflow of pond water or the like into each tank body 1. For high-concentration polluted water, a solid-liquid separator 12 may be provided in front of the purification unit 7 to supply separated water from which coarse particles have been separated to the purification unit 7. The solid-liquid separation device 12 will be described in detail with reference to FIG. 4.
The contaminated water that has flowed upward from the supply pipe 14
Then, the separated water is supplied from the treated water pipe 15 to the inlet 8 of the purification unit 7. Reference numeral 16 denotes a stirring device when the filter medium layer 13 is clogged. Note that an air supply pipe may be provided below the filter medium layer 13 to activate the aerobic fine substance.

Reference numeral 17 denotes a tread provided on the upper part of the tank body 1, which is supported on the upper part of the side wall of the tank body 1 as shown in FIG. So that it is always above the water surface. As shown in FIG. 3, a floating pier 18 is constituted by a large number of treads 17 on the purification unit 7 connected to the plurality of tanks 1. When you use it as a hydrophilic landscape facility,
It may be disposed on the shore of pond water or the like, or may be used as a floating pier 18 for an underwater observatory. Reference numeral 19 denotes a support standing upright on the upper portion of the side wall of the tank body 1 and supports a handrail 20 of the tread plate 17. The support 19 is used to fix the purification unit 7 moved to a desired position. ,
It may be driven into the bottom of the water.

[0010]

As described above, according to the present invention, a plurality of tanks provided with floats are detachably connected to each other, and the number of connections and the connection method are devised according to the amount of water in a pond, lake or marsh, and the degree of contamination. Thus, the purification unit can be reduced in size, and if a tread is provided above the tank body, it can serve as both a water purification facility and a hydrophilic landscape facility . The upper part of the purification unit can be used as floating piers, in which can be used as hydrophilic landscape facilities.
