Abstract

PURPOSE:To provide a purification apparatus which can be composed simply and can purify a whole reservoir without pollution even during purification by constituting the apparatus with a pump, a reaction tank, a compartment, and an ejection pipe and by forming the divided part so that flocks generated in the compartment, which are close to the surface of the water in the compartment, do not flow into the reservoir. CONSTITUTION:In an apparatus for purifying reservoir, a submersible pump 46 sends water in the reservoir to a reaction tank 45. A given amount of ozone air is sent from a magnetized ozone generator 28 to the reaction tank 45, and a given amount of dissolved coagulating agent is sent from a dissolved coagulating agent apparatus 29 to the reaction tank 45. In the reaction tank 45, water sucked, magnetized ozone air, and the coagulating agent are mixed thoroughly to be ejected into a compartment 40. In the water ejected, BOD and COD are decomposed by oxidation with the magnetized ozone, bacteria are sterilized, agricultural chemicals are decomposed, and flocks are formed from algae, SS, and others by the coagulating agent. The floating flocks being close to the surface of the water are prevented from flowing out by a float 41 to be collected in the compartment 40 to be prevented from diffusing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a purifying device for purifying a reservoir or the like.

[0002]

2. Description of the Related Art Conventionally, a reservoir attached to a golf course will be described as an example of a device for purifying a reservoir. The reservoir is equipped with a weir to prevent flooding due to heavy rain, and the weir is provided with an outlet to maintain a constant water level. However, it is formed so that it overflows from the weir and flows down in the event of heavy rainfall for one time. In recent years, environmental problems have been highlighted, and the quality of water discharged from the reservoir has become a problem. The discharged water is purified by the purification device shown in FIG. 6 and then discharged downstream. That is, the water discharged from the reservoir 1 flows into the water intake tank 5 through the through pipe 3 formed in the weir 2. Submersible pump 6 installed in intake tank 5
Sent to the biological filtration tank 7. On the other hand, air is blown into the biological filtration tank 7 through the blower 8, and the treated water is stored in the storage tank 9. The backwash water for the biological filtration tank 7 is stored in the backwash tank 11 through the pipe 10. A part of the treated water in the storage tank 9 is sprinkled on the reservoir 1 via the submersible pump 12, and the discharged amount is treated by the activated carbon adsorption device 15 via the submersible pump 13 and then discharged to the drainage channel 16. It

[0003]

Although the above-mentioned purification device can purify the discharged water, it cannot deal with the water in the reservoir. Therefore, there is a problem that the reservoir is cloudy and spoils the aesthetics. Therefore, it is conceivable to use the above-mentioned conventional equipment to circulate the water after being treated by the activated carbon adsorption device 15 to the reservoir 1, but the treatment device having the above-mentioned configuration has a problem in the treatment capacity. Not economical. Therefore, the present invention provides a purifying device that solves the above problems.

[0004]

The purification apparatus of the present invention comprises a pump for sucking and discharging water in a reservoir, a reaction tank for mixing the pumped water and a flocculant, and a partition for partitioning a part of the reservoir. And a jet pipe that guides water from the reaction tank to the partition, and the partition is formed so that flocs generated in the partition do not flow out to the reservoir near the water surface.

[0005]

The floc is formed by using a flocculant to purify the water in the reservoir, and the water containing the floc is ejected to the compartment formed in the reservoir. Since the partition part is formed so as to prevent the flocs generated in the partition part from flowing out of the vicinity of the water surface to the reservoir, the pollution occurs only in the partition part. Therefore, the reservoir can be purified without polluting the entire reservoir.

[0006]

Embodiments of the present invention will be described with reference to the drawings. (First Embodiment) FIG. 1 is an overall layout view of a water purification device, FIG. 2 is a plan view, and FIG. 3 is an enlarged view showing a side cross section of a reaction tank part. Reservoir 1 is discharge port 4 formed in weir 2.
Is kept at a constant water level. Although not necessarily required on the ground, a magnetized ozone generator 28 for reducing BOD and COD and a dissolving and aggregating agent device 29 used for removing SS as flocs are installed. The air from the air compressor 30a is adjusted to a constant amount by the constant flow valve 3 and then alternately switched to be used.
Oxygen is taken out to be further guided to, and is further ozonized by the magnetized ozone generator 32 in order to promote the oxidation, and then further magnetized, and then sent to the reaction tank 45 described later. The concentration of magnetized ozone sent to the reaction tank 45 can be adjusted,
An air compressor 30b that simply sends air to the reaction tank 45 is installed. Reference numeral 35 is a coagulant device, and the coagulant introduced into the dissolution tank 36 is dissolved by the stirrer 37 to a predetermined concentration and sent to the reaction tank 45 via the metering pump 38 and the discharge opening / closing valve 39. On the other hand, in the reservoir 1, a partition portion 40 partitioning a part of the reservoir 1 is formed by a float body 41. That is, the reservoir 1 is partitioned by the circular float body 41, and is connected to the anchor 42 so that the float body 41 does not move. Further, although not necessarily required for the float body 41, a net 43 hangs so that the formed flocs are not scattered over the entire reservoir 1 as much as possible.

A submersible pump 46 fixed on the base 54 sucks the water in the reservoir 1 and discharges the water into an inlet 47 formed so as to enter the side wall of the substantially cylindrical reaction tank 45 tangentially. The magnetized ozone air described above is also introduced into this portion through a pipe 48, and the above-mentioned dissolved coagulant is introduced into the reaction tank 45 through a pipe 49. Further, in the reaction tank 45, the ejection pipe 5 for discharging to the partition 40 is used.
1 is provided, and the ejection pipe 51 is composed of an ejection pipe 51a that discharges upward from the substantially central portion of the reaction tank 45 and an ejection pipe 51b that has a diameter larger than that of the ejection pipe 51a. A hole 52 is formed in the lower portion of the ejection pipe 51b so that the water in the reservoir 1 can be taken into the ejection pipe 51b by the jet flow of the ejection pipe 51a. Incidentally, in this embodiment, two sets of the above-mentioned devices are installed due to the processing amount,
The pair of ejection pipes 51b are fixed to each other by a connecting body 55, and are further bound to the float body 41 via a wire 56 so that they can float in water.

Explaining the operation of the above construction, the submersible pump 46 sucks the water in the reservoir 1 and sends it to the reaction tank 45. Further, a predetermined amount of ozone air is supplied to the magnetized ozone generator 28.
From the dissolution coagulant device 29 to the reaction tank 45 via the pipe 48 and from the dissolution coagulant device 29 via the pipe 49. In the reaction tank 45, the water from the submersible pump 46 enters in the tangential direction of the side surface of the reaction tank 45, so that a swirling flow occurs inside and the magnetized ozone air and the aggregating agent are sufficiently mixed and the jet pipes 51a and 51b are discharged. It is jetted to the partition section 40 through. In addition, the water in the reservoir 1 is entrained from the hole 52 by the jet flow from the jet pipe 51a and is jetted to the partition section 40 from the jet pipe 51b. BOD and COD of the water ejected into the compartment 40 are oxidatively decomposed by magnetized ozone, bacteria are sterilized, pesticides are decomposed, and algae, SS, etc. form flocs with a flocculant, and the floating flocs. Are prevented from flowing out from the vicinity of the water surface by the float body 41 and gather in the compartment 40. Therefore, only the inside of the partition 40 is clouded by the flocs, but the cloudiness is caused by the float body 41.
Prevents diffusion. As described above, the pollution treatment method in which the water in the reservoir 1 is circulated can be treated without impairing the overall aesthetic appearance because only the partition 40 is turbid and the other reservoirs 1 are not affected. It should be noted that the pollution in the reservoir 1 becomes a floc in sequence and collects in the partition 40, and the flocs eventually settle to purify the reservoir 1 as a whole to provide a beautiful appearance.

(Second Embodiment) This embodiment will be described with reference to FIG. 4 showing the overall arrangement of the purifying device for the reservoir 1 and FIG. 5 showing the plan view. In addition, this embodiment is different from the above embodiment in the reaction tank 45.
Since the position of the partition 40 is different, detailed description will be omitted. The same magnetized ozone generator 28 and dissolution coagulant device 29 as in the first embodiment are installed on the ground, and they are sent to the reaction tank 45 via pipes 48 and 49, respectively. On the other hand, in the reservoir 1, a partition section 40 partitioning a part of the reservoir 1 is arranged with a float body 41 at a position different from the reaction tank 46. A jet pipe 51b is maintained in a floating state at the center of the partition 40 via a rope. Further, the submersible pump 46, the reaction tank 45, and the ejection pipe 51a
Has the same configuration as that of the above-described embodiment, and is floated in water by a float body 63 fixed by an anchor 64.
The water ejected from the ejection pipe 51a is connected to the ejection pipe 51b through a pipe 65. According to the above configuration, the water sucked by the submersible pump 46 reacts with the magnetized ozone air and the coagulant in the reaction tank 46, and is discharged from the ejection pipe 51b into the compartment 40 through the ejection pipe 51a and the pipe 65. It The jetted water contains flocs, and the flocs are prevented from flowing out by the float body 41, and only the inside of the partition becomes turbid, and the flocs precipitate with the passage of time and the entire reservoir 1 is purified. In this embodiment, the place where the flocs are discharged can be set to any place in the reservoir 1, and for example, it can be installed in a place that cannot be seen from the road.
It can be presented in a state where 0 is not visible, and it does not spoil the appearance.

In the above-mentioned embodiment, all of the partition parts 40 are formed in a floating state via the float body. However, a weir surrounding the water surface is formed at a specific place with concrete or the like, and the weir of the weir is formed. It goes without saying that the lower part may be formed into a shape that can be inserted into the reservoir 1. That is, floating flocs can be prevented from flowing out by the weir, and water can form a circulation path from the lower part of the weir to the reservoir, and over time, the flocs settle and purify the entire reservoir. Also, the treated water is BO
Needless to say, when it is not necessary to reduce D, it is not necessary to supply ozone-containing air to the reaction tank, and it can be applied not only to a reservoir attached to a golf course, but also to a place where water is stored such as a pool.

[0011]

EFFECT OF THE INVENTION The purifying device of the present invention can be simply constructed and can purify the entire reservoir without polluting even during the purifying. In addition, by installing the partition part in an invisible place, it is possible to perform purification without impairing aesthetics.
