Even in a clean pond with natural inflow and natural discharge, if the inflow water becomes polluted, the natural purification ability of gravel etc. will be exceeded and the pond will become acid-free, causing fish and other organisms to die and emit an odor. Conversely, the pond becomes a source of sewage. When the level of pollution is low, aerating the surface water can improve the situation, but it is difficult to purify the sludge that has accumulated on the bottom of the pond, and when the level of pollution is severe, thick sewage becomes a problem. Biological treatment using purifying microorganisms is required.

しかしながら、池全体を処理槽として浄化を行うことは
、臭気の問題もあり、また、景観上からも好ましぐない
However, using the entire pond as a treatment tank for purification poses an odor problem and is also undesirable from a landscape perspective.

Furthermore, organic matter that is relatively easy to decompose is decomposed during the inflow process and sedimentation process, but the sludge at the bottom of the pond that has accumulated over many years is a sludge that is relatively decomposable and has a high content of one element.
This alone is not enough to decompose organic matter and denitrify, but it is important to mix it with newly inflowing wastewater in a well-balanced manner.

The purpose of the present invention is to perform intermittent 4-air purification, mix the newly inflowing sewage in a balanced manner, sufficiently cultivate sewage purifying microorganisms, and gradually promote organic decomposition and denitrification (in the upper layer of Kuku Pond). To provide a method and device which can purify sludge at the bottom of a pond, suppress generation of odor, and do not damage the landscape of the pond.

In the pond water purification method according to the present invention, a wide IJEtJ product is ensured by installing an inverted funnel-shaped flexible screen from the upper surface of the central part of the pond to the periphery of the bottom of the pond. By introducing inflow water from the upstream river into the processing chamber, which is narrowed 1 m above, the inclined surface of the screen is expanded so as to curve outward, thereby maintaining the volume of the processing chamber and increasing its volume. The volume of the annular water storage part with a narrow bottom formed on the outer periphery is reduced, and the treatment chamber is aerated for a predetermined period of time, and then this is paused for a predetermined period of time, during which time the sludge is allowed to settle and the supernatant water is removed. The sloping surface of the screen is moved inwards in response to the increase in the amount of water in the annular storage section and the decrease in the amount of water in the treatment chamber due to the transfer of the above-mentioned water or inflow water from the upstream river. By contracting in a curved direction, the volume of the processing chamber is reduced and the volume of the annular water storage portion is expanded.

When the inflow water from the upstream river R1 is introduced into the processing chamber 2, the inclined surface of the flexible curtain l expands to bend outward, increasing the volume of the processing chamber 21. At the same time, the volume of the annular water storage portion 2b is reduced. This is done not only by the volume retention line of the process M2@, the difference in water volume with the annular water storage section, and the hydrostatic pressure based on the gravity distribution, but also by the water flow pressure of the air flow inside the process chamber 2a. Note that the inflow water from the upstream river R1 may be introduced into the processing chamber 23 by natural inflow due to the water level difference with the downstream side, or,
It may be carried out by forced introduction using a pump or the like.
