る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating polluted water, and more specifically, the present invention relates to a method for treating polluted water, and more particularly, a hanging tail is installed in polluted water with a gap, and the water content of the polluted water to be treated is 30 to 90%.
This is a method for treating polluted water by suspending a solid or semi-solid polyacrylamide flocculant.

剤を予め水に溶かして溶液状となし、これをシヤ
ワー等により処理水域内に添加していた。 The present inventor has provided a treatment method in which hanging tails are arranged in a row with gaps and extended in a polluted water treatment area. Generally, a coagulant is used in this treatment method in order to promptly settle the pollutant particles in the polluted water. The method of adding this coagulant is to dissolve the coagulant in water in advance to form a solution, which is then added to the treated water area using a shower or the like.
しかしながら例えば凝集剤として広く使用され

所望する均一な溶液とならなかつた。そこで従来
は強力な撹拌装置や特殊な構造を有する溶解装置
によつて溶解を行つていた。このように従来水に
溶解するために煩雑な作業を要していた。 However, for example, polyacryamide, which is widely used as a flocculant, has extremely poor solubility in water and when dissolved normally, it becomes lumpy and cannot form the desired uniform solution. Therefore, in the past, dissolution was carried out using a powerful stirring device or a dissolving device with a special structure. As described above, conventional methods require complicated work to dissolve in water.
本発明者はこれら従来の煩雑な作業を要するこ
となく好適に汚濁水を処理する方法につき種々研
究を重ねた結果本発明を完成するに至つた。 The present inventor has completed the present invention as a result of repeated research on a method for appropriately treating polluted water without requiring these conventional complicated operations.

ることもできる。 That is, in the present invention, as shown in FIG. 1, for example, sheet-like hanging tails 1 are arranged and extended with a gap 2 between them. In this case, it is preferable to attach a float (not shown) at an appropriate location to hold the hanging tail 1 in the water. It is also possible to use a hanging tail 4 with a float 3 as shown in FIG.

ためには水分含量を低くすればよい。 On the other hand, the polyacrylamide flocculant used in the present invention has a solid or semi-solid form with a water content of 30 to 90%. These molded flocculants may be string-like, for example, strung together in a string shape, or may be placed in a net-like bag and suspended in water. The shape of the molded flocculant is plate-like, bead-like,
It can be formed into various shapes such as columnar or coarse grained. This flocculant can be prepared by completely dissolving granular polyacrylamide in water, then placing it in a mold or the like and drying it. It can also be prepared in a drying step in the process of producing polyacrylamide from acrylamide. The water content of the flocculant may be selected depending on the desired dissolution rate. That is, if you want to speed up the dissolution rate, you can increase the water content, and conversely, if you want to slow down the dissolution rate, you can lower the water content.

したものでもよい。 When the molded polyacrylamide flocculant is actually used, it is hung, for example, in the form of a blind 5, as shown in FIG. 3, and suspended in polluted water. If it is suspended, it may be installed near the hanging tail, but the fourth
As shown in the figure, treatment can also be carried out by spreading a coagulant in the form of a blind on the inside of a hanging tail 6 and injecting polluted water into the surrounding area from a polluted water inlet 8. It is also possible to spread multiple blind-like flocculants. Incidentally, it may be used in combination with, for example, acrylic acid soda or a sulfuric acid powder product mixed and solidified.
