Description

本発明は、汚濁水の処理等に用いられる薬注装置に係り、さらに詳しくは汚濁水の処理等に用いられる水中用薬注装置に関する。 The present invention relates to a chemical injection device used for treatment of polluted water and the like, and more particularly to an underwater chemical injection device used for treatment of polluted water and the like.

従来、汚濁水の処理方法の代表的な方法として凝集法が広く知られている。一般的な方法としては急速撹拌槽の表層水に凝集剤を添加して行われていた。しかしながら、この方法では急速撹拌槽内で汚濁水と凝集剤を全般的に混合することを形成することは困難であり、さらに短時間の混合でフロックを形成することも困難であった。 Conventionally, a coagulation method is widely known as a representative method for treating contaminated water. As a general method, a flocculant is added to the surface water of the rapid stirring tank. However, in this method, it is difficult to form a general mixing of the polluted water and the flocculant in the rapid stirring tank, and it is also difficult to form flocs by mixing in a short time.

そこでこれらの方法の改良法として処理槽内に小区画域を設け、該小区画域内には不均一性触媒の多面積接触体を内在させ、かかる小区画域内に、酸性凝集剤と、該酸性凝集剤が弱酸性から弱アルカリ性のｐＨに調整するのに必要な化学当量の均一性触媒のアルカリ剤とを添加することを特徴とする原水の処理方法が提案されている（特許文献１）。   Therefore, as an improved method of these methods, a small compartment is provided in the treatment tank, a multi-area contact body of a heterogeneous catalyst is contained in the small compartment, and the acidic flocculant and the acidic flocculant are contained in the small compartment. There has been proposed a raw water treatment method characterized by adding a chemical equivalent of a homogeneous catalyst alkaline agent necessary for adjusting the flocculant from weakly acidic to weakly alkaline pH (Patent Document 1).

特開２０１２−６１４２６号公報JP 2012-61426 A

前記特許文献１には、処理層内に小区画域を設け、該小区画域内に凝集剤を添加することが開示されている。そして小区画域として用いられるものとして、ロート形の筒状体が開示され、さらに該ロート形の筒状体の周壁面にスリットを設けることが開示されている。しかしながら、このロート形の筒状体を用いた場合、従来の小区画域を設けない場合に比べれば格段に混合効率は向上したが、未だ満足にするものではなかった。
本発明者は、さらに効率的に汚濁水中の汚濁物質をフロック化させるかについて種々研究を重ねた結果本発明を完成するに至った。 Patent Document 1 discloses that a small compartment is provided in the treatment layer and a flocculant is added to the small compartment. And as what is used as a small division area, the funnel-shaped cylindrical body is disclosed, and also providing a slit in the peripheral wall surface of the funnel-shaped cylindrical body is disclosed. However, when this funnel-shaped cylindrical body was used, the mixing efficiency was significantly improved as compared with the case where a conventional small compartment was not provided, but it was not yet satisfactory.
The inventor of the present invention has completed the present invention as a result of various studies on whether or not the pollutant in the polluted water can be more efficiently flocked.

すなわち、本発明は、逆円錐形のテーパーコーン部の先端に管状部を設け、かつ前記テーパーコーン部の側壁に水導入口を設けた水中用薬注装置および逆円錐形のテーパーコーン部の先端に管状部を設け、かつ前記テーパーコーン部の側壁に水導入口を設けてなる水中用薬注装置の下部に、間隔を設けて、逆円錐形のテーパーコーン部の先端に管状部を設けた水中用薬注装置を少なくとも１個垂設することを特徴とする水中用多段薬注装置に関する。 That is, the present invention provides a submerged chemical injection device in which a tubular portion is provided at the tip of an inverted conical tapered cone portion, and a water introduction port is provided on a side wall of the tapered cone portion, and the tip of the inverted cone tapered cone portion A tubular portion is provided at the tip of the inverted cone-shaped tapered cone portion at a lower portion of an underwater drug injection device in which a water inlet is provided on the side wall of the tapered cone portion. The present invention relates to an underwater multistage chemical injection device characterized by suspending at least one underwater chemical injection device.

本発明の薬注装置を用いることによって、凝集剤と汚濁水の接触頻度が高まることから、高濁度のフロックを形成させることができ、それに伴い汚濁水の諸条件に左右されにくいため、従来のような凝集剤の多量注入を防止することができる。また本発明の薬注装置は処理する汚濁水の水流を利用するため、特に撹拌装置等を設置する必要もないので省エネルギー化を行うことができる。 Since the contact frequency of the flocculant and the polluted water is increased by using the chemical injection device of the present invention, a high turbidity floc can be formed, and accordingly it is difficult to depend on the various conditions of the polluted water. It is possible to prevent a large amount of the flocculant from being injected. Moreover, since the chemical injection device of the present invention uses the water flow of the polluted water to be treated, it is not necessary to install a stirring device or the like, so that energy can be saved.

また図２に示すように水導入口５を有する水中用薬注装置１の下部に例えば水導入口５を有しない水中用薬注装置６を間隔を設けて垂設することもできる。この両者を固定する方法としては、例えば水導入口５を有する水中用薬注装置のテーパーコーン部２の外壁面に、ネジ穴を有する支持部７を設け、また下部に設けられた水中用薬注装置６のテーパーコーン部の外壁部にもネジ穴を有する支持部８を設ける。そしてネジ棒９によってそれぞれ支持部７と支持部８に螺着する。 The relationship between the diameter A of the upper edge of the tapered cone portion 2 and the diameter B of the tubular portion 4 in the underwater chemical injection device of the present invention is preferably in the range of A: B = 1: 0.05 to 0.5. The length C of the tubular portion 4 is preferably A: C = 1: 0.05 to 0.5 with respect to the diameter A of the upper edge portion of the tapered cone portion 2.
Further, as shown in FIG. 2, for example, an underwater chemical injection device 6 that does not have the water introduction port 5 can be suspended at a lower portion of the underwater chemical injection device 1 having the water introduction port 5. As a method for fixing both of them, for example, a support portion 7 having a screw hole is provided on the outer wall surface of the tapered cone portion 2 of the underwater drug injection device having the water introduction port 5, and the underwater drug provided at the lower portion. A support portion 8 having a screw hole is also provided on the outer wall portion of the tapered cone portion of the injection device 6. Then, the screw rod 9 is screwed to the support portion 7 and the support portion 8 respectively.

また図３に示すように、水中用薬注装置１と水中用薬注装置６との間に間隔を設けて水中用薬注装置１０を設けることもできる。これら固定方法は前記した様にそれぞれに支持部を設けネジで固定することによって構成することができる。この際水中用薬注装置１０は、水中用薬注装置６のそのテーパーコーン部の内に収容する形で設けることが好ましい。

As described above, these fixing methods can be configured by providing support portions for each and fixing them with screws. At this time, it is preferable that the underwater chemical injection device 10 is provided so as to be accommodated in the tapered cone portion of the underwater chemical injection device 6.
The relationship between the diameter A of the upper edge portion of the tapered cone portion of the underwater chemical injection device 1 and the diameter D of the upper edge portion of the tapered cone portion of the underwater chemical injection device 10 is [A: D = 1: 0.1. ~ 0.8] is preferred.

次に、本発明の水中用薬注装置の使用方法について説明する。
図４に示すように水中用薬注装置１のテーパーコーン部２の上縁部１１を水面より上に設けると共に水導入口５を前記テーパーコーン部２の接線方向から汚濁水の水流が導入されるように設ける。水導入口５からテーパーコーン部２に流入した汚濁水は渦巻流を生起する。ここに上部から例えばアルカリ剤１２と無機系凝集剤１３を添加すると渦巻流によって撹拌混合されると共に汚濁水の汚濁物質を高濃度凝集でフロック化させる。このフロック化された汚濁粒子は高濃度凝集体となり、渦巻流と共に下降し、下部に設けられたテーパーコーン部を有する水中用薬注装置１０に移行する。
またテーパーコーン部２と水中用薬注装置１０のテーパーコーン部との間に間隔を有することから、該間隔部より汚濁水が流入して、さらに渦巻流を生起させ、水中用薬注装置１０のテーパーコーン部に導入され、ここで上部から下降してきた高濃度凝集体と接し、汚濁物質が付着する。このようにして肥大化したフロックはテーパーコーン部を有する水中用薬注装置６の管状部１４から汚濁水中に均一に分散され汚濁水中に混合されて、さらにフロックが肥大化して汚濁水中の汚濁物質を除去することができる。
更に図４に示した構造とすることによって、水中用薬注装置１内の水域に水導入口５から汚濁水が入り最初の渦巻流１６が生起する。次に水中用薬注装置１と水中用薬注装置６との隙間から汚濁水が入り２段の渦巻流１７が生起する。２段の渦巻流１７は最初の渦巻流１６より速い。更に２段の渦巻流１７は水中用薬注装置１の管状部４と水中用薬注装置１０との隙間および水中用薬注装置１０と水中用薬注装置６との隙間にそれぞれ渦巻流１８、渦巻流１９を生起させる。最初の渦巻流１６は撹拌流と成り、渦巻流１８は管状部４を通る汚濁水の引き込み流と撹拌流と成り、渦巻流１９は水中用薬注装置１０の汚濁水の引き込み流と成って、汚濁水を段階的に撹拌することで、凝集剤と汚濁水の接触頻度を高め、短時間でかつ汚濁水の諸条件に左右されにくい状態でフロックの形成を確実に行う水中用薬注装置とすることができる。 Next, the usage method of the underwater chemical injection apparatus of this invention is demonstrated.
As shown in FIG. 4, the upper edge portion 11 of the tapered cone portion 2 of the submerged chemical injection device 1 is provided above the water surface, and the water introduction port 5 is introduced with a flow of contaminated water from the tangential direction of the tapered cone portion 2. Provide so that. The polluted water that has flowed into the tapered cone portion 2 from the water inlet 5 causes a spiral flow. If, for example, the alkali agent 12 and the inorganic flocculant 13 are added from the upper part, the mixture is stirred and mixed by a swirl flow, and the pollutant of the polluted water is flocked by high concentration aggregation. The flocked contaminated particles become high-concentration aggregates, descend with the swirl flow, and move to the underwater chemical injection device 10 having a tapered cone portion provided in the lower part.
In addition, since there is a gap between the tapered cone part 2 and the tapered cone part of the underwater chemical pouring device 10, the contaminated water flows in from the gap part and further causes a swirl flow. In contact with the high-concentration aggregates that have been introduced from the upper part of the taper cone part and descended from the upper part, the pollutant adheres. The flocs enlarged in this way are uniformly dispersed in the contaminated water from the tubular portion 14 of the submerged chemical injection device 6 having a tapered cone portion and mixed into the contaminated water, and the flocs are further enlarged and contaminated substances in the contaminated water. Can be removed.
Further, by adopting the structure shown in FIG. 4, contaminated water enters the water area in the underwater chemical injection device 1 from the water inlet 5, and the first spiral flow 16 is generated. Next, polluted water enters through the gap between the underwater chemical injection device 1 and the underwater chemical injection device 6 to generate a two-stage spiral flow 17. The two-stage spiral flow 17 is faster than the first spiral flow 16. Further, the two-stage swirl flow 17 is a swirl flow 18 in the gap between the tubular portion 4 of the underwater chemical injection device 1 and the underwater chemical injection device 10 and in the clearance between the underwater chemical injection device 10 and the underwater chemical injection device 6. Then, the spiral flow 19 is generated. The first swirl flow 16 becomes a stirring flow, the swirling flow 18 becomes a drawing flow and a stirring flow of the polluted water passing through the tubular portion 4, and the swirling flow 19 becomes a drawing flow of the polluted water of the submerged chemical injection device 10. In addition, the agitating device of the polluted water increases the frequency of contact between the flocculant and the polluted water, and the underwater chemical injection device ensures the formation of flocs in a short time and in a state that is not easily affected by the various conditions of the polluted water. It can be.

本発明の水中用薬注装置を水中に設置する場合、水流に対し水導入口５の角度を調整することによってテーパーコーン部２内に生起する渦巻流の流れの速さを調整することができる。 When the underwater chemical injection device of the present invention is installed in water, the flow speed of the spiral flow generated in the tapered cone portion 2 can be adjusted by adjusting the angle of the water inlet 5 with respect to the water flow. .

また汚濁水に水流がなかったり、水流が弱い場合には、図５に示すようにテーパーコーン部２を有する水中用薬注装置１の下部に撹拌装置１５を設け回転させることによって、装置全体に渦巻流を生起させることができる。 Further, when there is no water flow in the polluted water or when the water flow is weak, as shown in FIG. 5, a stirring device 15 is provided at the lower portion of the underwater chemical injection device 1 having the tapered cone portion 2 and is rotated. A spiral flow can be generated.
