Description
【発明の詳細な説明】 本発明はヘドロ投棄地構築方法に関するものである。[Detailed description of the invention] The present invention relates to a method for constructing a sludge dumping site.
従来、投棄地周囲の堰堤は鋼矢板で作っていたが、これ
によると透水性が悪く、投棄したヘドロ中の水切りを迅
速に行なえず、また多数の鋼矢板を使うことから経済的
でなかった。Previously, the dams around the dumping site were made of steel sheet piles, but this had poor water permeability, made it impossible to drain the dumped sludge quickly, and was uneconomical as it required a large number of steel sheet piles. .
そこで本発明は上記問題点を解決し得るヘドロ投棄地構
築方法を提供するもので、以下その一実施例を第１図、
第２図に基づいて説明する。Therefore, the present invention provides a method for constructing a sludge dumping site that can solve the above-mentioned problems.
This will be explained based on FIG.
高含水率のヘドロの処理として、このヘドロに凝集剤を
供給したのち濃縮槽に入れて濃縮させ、そして濃縮ヘド
ロを取出して凝結剤（例えば水ガラス系凝結剤など珪酸
塩系凝結剤）を添加したのち混合させ、次いでこの濃縮
ヘドロに硬化剤（例えば酸または酸性物質などからなる
硫酸塩硬化剤）を添加し混合したのち埋立地への投棄を
行なう方法が考えられている。To treat sludge with a high water content, a coagulant is supplied to the sludge, then it is placed in a concentration tank to be concentrated, and the concentrated sludge is taken out and a coagulant (for example, a silicate coagulant such as a water glass coagulant) is added. A method has been considered in which the concentrated sludge is then mixed, and then a hardening agent (for example, a sulfate hardening agent made of an acid or an acidic substance) is added to the concentrated sludge, mixed, and then dumped in a landfill.
そして凝結剤の添加量を増すことによって、ようかん状
に固くしまったヘドロを作ることができる。By increasing the amount of coagulant added, it is possible to make sludge that is hard and hard like a beaker.
本発明では第１図に示すように、凝結剤の大量添加によ
りようかん状に固化処理したヘドロ１とこのへドロ１の
中心部に設けられる砕石などの骨材６によって、投棄地
２周囲の基盤３上に堰堤４を作るものである。In the present invention, as shown in FIG. 1, the sludge 1 that has been solidified into a funnel-like shape by adding a large amount of coagulant and the aggregate 6 such as crushed stone provided in the center of the sludge 1 are used to form the foundations around the dumping site 2. A dam 4 is constructed on top of the dam 3.
そして堰堤４で囲まれた投棄地２に対して、第２図に示
すように凝結剤の添加量が少ない（定常添加）へドロ５
を投棄するのであるが、ここで堰堤４は中心部に入れら
れた骨材６によって透水性が良いことから、ヘドロ５の
水切りは迅速に行なわれる。Then, as shown in Figure 2, for the dumping site 2 surrounded by the dam 4, the amount of coagulant added is small (constant addition).
However, since the dam 4 has good water permeability due to the aggregate 6 placed in the center, the sludge 5 can be drained quickly.
また前述のように堰堤４の中心部に砕石などの骨材６を
入れであることにより、この堰堤４の強度を増すことが
できる。Further, as described above, by placing aggregate 6 such as crushed stone in the center of the dam 4, the strength of the dam 4 can be increased.
また骨材６を取り巻くヘドロ１内に砂やバラスなどの骨
材を混合して透水性を高めてもよい。Alternatively, aggregate such as sand or ballast may be mixed into the sludge 1 surrounding the aggregate 6 to increase water permeability.
以上、実施例で述べた本発明によると、凝結剤の添加量
を多くして固化処理したヘドロとこのヘドロの中心部に
設けられる砕石などの骨材により投棄地周囲の堰堤を作
ることから、従来の鋼矢板を使用する方法に比べて、投
棄したヘドロ中の水切りを迅速に行なうことができ、ま
た凝結剤の増量は鋼矢板使用に比べて安価であることか
ら全体を経済的にできる。According to the present invention described in the examples above, a dam around a dumping site is created using sludge that has been solidified by adding a large amount of coagulant and aggregate such as crushed stone provided in the center of this sludge. Compared to the conventional method of using steel sheet piles, the water in the dumped sludge can be drained quickly, and increasing the amount of coagulant is cheaper than using steel sheet piles, making the whole process more economical.
特に本発明によれはヘドロの中心部に砕石などの骨材を
入れであることにより堰堤の透水性が一層良くなり、且
つ堰堤の強度を向上されることができるものである。In particular, according to the present invention, by putting aggregate such as crushed stone in the center of the sludge, the water permeability of the dam can be further improved and the strength of the dam can be improved.
