Abstract

PURPOSE:To effectively prevent the diffusion of turbid substance in water by a method in which sheet films are laid at an interval on the surface and bottom of water, and an aperture is provided in the sheet laid on the surface of water. CONSTITUTION:A sheet 1 is connected to a float 2 on water surface and hung down below the water surface, and a sheet film 3 is hung down from a float 4 to the bottom under water at a give distance (h) from the sheet film 1. Since the sheet film 1 has apertures and also a aperture is provided between these sheet films 1 and 3, the flow of water is circumvented even when the amount of turbid water to be treated is increased. The flow rate of the water can thus be reduced and the sedimentation of turbid substances can be effectively attained before the sheet, films.

Description

【発明の詳細な説明】 本発明は、汚濁水処理におりる汚濁拡散防止方法に関す

従来汚濁拡散防止方法としては種々の方法が提案されて
いる。その一つの方法が一枚の辿鹸膜で汚濁発生箇所を
囲繞する方法である。しかしながらかかる方法は可及、
的に密閉状Ｊルとするため、汚濁水の処理量が多くなる
とシート膜下部と水底との僅かな間隙部より汚濁水が勢

くなって拡散速度を速める結果となり所期の目的が達成
できない欠点がある。また他の方法として垂下テールを
それぞれ間隙を設けて連設してなる処理方法が提案され
ている。この方法は汚濁水の処理量が増大しても隣接す

部迄に充分な間隔があるために前記のような欠点もなく
所期の目的を達成することができる。Conventionally, various methods have been proposed as methods for preventing pollution diffusion. One method is to surround the area where the contamination occurs with a single sapon membrane. However, such a method is possible.
Since the system is sealed, when the amount of polluted water to be treated increases, the polluted water will forcefully flow out from the small gap between the bottom of the sheet membrane and the bottom of the water, and the flow rate of the polluted water will increase. This has the disadvantage that the intended purpose cannot be achieved because the diffusion rate is increased. As another method, a treatment method has been proposed in which hanging tails are arranged one after the other with gaps between them. Even if the amount of polluted water to be treated increases, this method can achieve the intended purpose without the above-mentioned drawbacks because it creates a gap between adjacent hanging tails and there is a sufficient distance between the lower part of the hanging tail and the bottom of the water. can be achieved.

本発明者は前記した後者の処理法につきさらに種々検討
を加えた結果、本発明方法を完成するに至った。The present inventor conducted various further studies on the latter treatment method described above, and as a result, completed the method of the present invention.

すなわち、本発明はシート膜を水面部および水底部に間
隔を置いて展張した汚濁拡散防止方法である。That is, the present invention is a pollution diffusion prevention method in which sheet membranes are spread at intervals on the water surface and the water bottom.

り垂下せしめる。First, as shown in Figure 1, a sheet film l is placed on the water surface (7O-).
A sheet membrane 3 is suspended from the bottom of the water by a float 4 at a desired distance (h) from the sheet membrane 1.

することができる。This sheet film 1 has a gap 5 in the sheet film. As a specific example, for example, two hanging tail float fences (Batlesia (trade name, manufactured by Nippon Solid Co., Ltd.)) may be installed and extended. Further, the present invention can also employ a spreading method as shown in FIG.

拡散防−止を効果的に行うことができる。According to the method of the present invention, even if the amount of contaminated water to be treated increases, a gap is provided in the sheet membrane spread over the water surface, and a gap is maintained between the sheet membranes installed at the water surface and the bottom of the water. Therefore, the water flow rate can be diverted, and the water flow rate can also be reduced compared to conventional methods. According to the present invention, it is possible to effectively settle pollutants in front of the sheet membrane, and it is possible to effectively prevent the spread of pollutants by controlling the flow rate.
