方法および水域浄化装置に関する。The present invention relates to a golf course or a pond of a park,
In water bodies such as dug, lakes, rivers, dam lakes, for example,
The present invention relates to a method and an apparatus for purifying water bodies by removing pollutants including phytoplankton such as water-blooms, and in particular, purifying water by moving pollutants in water bodies at any waterside of water bodies to purify water. The present invention relates to a water area purification method and a water area purification apparatus that can return the polluted water to a water area and cake the removed pollutants.

る。2. Description of the Related Art Conventionally, purification of water is carried out by pumping polluted water to a transfer storage tank attached to a carrier, transporting raw water containing pollutants as it is, and purifying the water away from the water. Pollutants are removed at treatment plants.

【発明が解決しようとする課題】しかしながら、このよ

ある。すなわち、従来方式によれば、水域で原水を取水
する過程と、その原水を陸上輸送する過程と、浄化処理
場等で汚染物質を除去する過程が必要であり、所要時間
や所要人員等の面から処理効率が悪いという問題があ
る。However, the conventional example having such a structure has the following problems. That is, according to the conventional method, a process of taking raw water in the body of water, a process of transporting the raw water by land, and a process of removing pollutants at a purification plant or the like are required, and it takes time and personnel. Therefore, there is a problem that processing efficiency is poor.

場との間で複数回往復させなければならず、処理効率が
極めて悪いという問題もある。In addition, for example, when water is contaminated over a wide area such as a lake or dam lake, there is a limit to the capacity of the transfer tank of the conventional vehicle for transporting raw water over land, and therefore a large number of transportations are required. There is also a problem that the treatment efficiency is extremely poor because a car must be used or a small number of transport vehicles must be reciprocated multiple times between the water area and the purification plant.

浄化水を水域に還流する過程とがさらに必要になり、処
理効率が一層悪くなるという問題がある。Furthermore, in the conventional method, since the raw water is carried away to the purification plant, it is feared that the amount of water in the water area will decrease and the environment will be adversely affected. So, for example,
It may be possible to return purified water after removing pollutants at the purification plant to the original water area, but in this case, the process of transporting the purified water from the purification area to the original water area and the transported purification water. There is a problem that the process of recirculating water to the water area is further required and the treatment efficiency is further deteriorated.

It is preferable to use an axial flow pump or the like that is less likely to be clogged with dust such as plastic contained in the raw water to be pumped. By raising the raw water suction port 11 above the water surface of the water body, it is convenient to purify the raw water containing pollutants such as water-bloom floating near the water surface of the water body. Further, if a raw water suction port that sinks into the water body is used instead of the above-mentioned water surface floating type raw water suction port 11, it is also possible to purify raw water that contains pollutants that float deep inside the water region or settle in the water region.
Furthermore, the water surface floating type raw water suction port 11 and the pump 1
2, and the water intake device 1 may be configured to include both the raw water suction port that sinks into the water area and the pump that pumps the raw water from the suction port. The raw water taken by the water intake device 1 is supplied to the filtration device 2.

Then, the raw water sent into the filtration drum 21 is the filtering material attached to the filtration drum 21 due to the differential pressure Δp between the liquid level in the filtration drum 21 and the liquid level in the filtered water receiving tank 22 lower than this. After being filtered, the filtered water is stored in the filtered water receiving tank 22, and most of it is returned to the original water area through the discharge pipe 26. Further, the filtered material (contaminant) remaining as a result of the above-mentioned filtration adheres to the filter medium and is moved between the backwash nozzle 24 and the drainage receiving tank 25 as the filter drum 21 rotates. A part of the filtered water stored in the filtered water receiving tank 22 is sent to the backwash nozzle 24 by the pump 23, and the filtered water is discharged from the back surface (outer peripheral surface side of the filtering drum 21) of the filtering material and backwashed. The filtered material attached to the filter material is collected in the drainage receiving tank 25 together with the filtered water. The water containing a large amount of the filtered material (concentrated to a higher concentration than the raw water) collected in the drainage receiving tank 25 is stored in the drainage storage tank 27.

いう特徴がある。The filter material used in the rotary drum type continuous filter device 2 is important for removing minute contaminants such as plankton such as water-bloom. For example, naps of fibers having a thickness of about 0.1 to 20 μm lie in a substantially constant direction (direction opposite to the rotation direction of the filtration drum 21) on the surface of a base material made of a woven or knitted fabric described below, A filter material that functions as a filter layer is suitable. The woven or knitted fabric that serves as the filtering material usually has a thickness of 0.1 to 2
About 0 μm polyamide, polyester, polyolefin, polyvinyl alcohol, polyfluoroethylene,
A fiber made of synthetic fiber such as polyacrylonitrile is used. The type of woven fabric or knitted fabric is not particularly limited, but a satin woven fabric is preferable for the woven fabric, and a half-knit tricot fabric is preferable for the knitted fabric because it easily stands up. The ultrafine fibers having a thickness of 0.1 μm or less have insufficient strength, and the fibers having a thickness of 20 μm or more are likely to stand upright after napping, which makes it difficult to form a good filtration layer. As the napping method, conventionally known means can be used. For example, filter cloths (filter materials) and devices described in Japanese Patent Publication No. 4-1647 and Japanese Patent Publication No. 4-9081 correspond to this. Further, this filter material is capable of suitably filtering out minute contaminants such as planktons, and is also easy to peel off the filtered material from the surface (the inner peripheral surface side of the filtration drum 21), so that the filtered material obtained by backwashing can be easily removed. It has a characteristic that it is difficult for it to be clogged for a long period of time.

However, the present invention is not limited to this, and it is possible to obtain a predetermined size from raw water. As the filtering device 2, for example, a moving bed type sand filtering device or the like that can continuously wash the filtering material may be used as long as it is a filtering device capable of filtering out minute contaminants.

The condensed flocculated water containing a large amount of the filtrate is supplied to the dehydrator 4. By coagulating flocs of the filtered material in this manner, the cake-making efficiency of the filtered material (recovery rate of the filtered material) in the dehydrator 4 described later is improved.
