【考案の詳細な説明】 本考案は、下水や砕石場の懸濁水などの汚濁水処理設備
における薬液供給装置の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a chemical solution supply device in a facility for treating contaminated water such as sewage or suspended water from a stone crushing plant.

一般に、砕石場などにおける濁水処理設備において、源
濁水を沈降槽で清水とスラリーとに分離する際、その分
離効果を高めるために該源濁水に薬液たとえば高分子凝
集剤溶液を連続的に注入しながら処理している。Generally, in turbid water treatment facilities such as stone crushing plants, when source turbid water is separated into fresh water and slurry in a settling tank, a chemical solution such as a polymer flocculant solution is continuously injected into the source turbid water to enhance the separation effect. I am processing it while doing so.

この場合、高分子凝集剤溶液は、凝集剤溶解槽内で水に
粉末高分子凝集剤を投入しながら攪拌し溶解して製造さ
れるが、これを充分に溶解するためには１〜２時間程度
強制攪拌する必要がある。In this case, the polymer flocculant solution is produced by stirring and dissolving the powdered polymer flocculant in water in a flocculant dissolving tank, but it takes 1 to 2 hours to fully dissolve the polymer flocculant. It is necessary to forcefully stir the mixture.

従って、単一の溶解槽で溶解しながらその溶液を順次取
出して使用するということはできず、そのため、凝集剤
の溶解と溶液の取出しとは交互に行なわなければならな
い。Therefore, it is not possible to sequentially take out and use the solution while dissolving it in a single dissolving tank, and therefore, the dissolving of the flocculant and the taking out of the solution must be carried out alternately.

すなわち単一の溶解槽だけでは凝集剤溶液を連続的に取
出して前記源濁水に連続的に注入するということはでき
ないのである。In other words, it is not possible to continuously take out the flocculant solution and continuously inject it into the source turbid water using only a single dissolution tank.

そのために、従来では一基の処理設備に対し、同じ機能
を有する二基の溶解槽を並列に接続していた。For this reason, conventionally, two dissolution tanks having the same function were connected in parallel to one processing facility.

そして、まず一方の溶解槽で凝集剤溶液を製造した後、
同種より凝集剤溶液を順次取出しながら源濁水に注入し
つつ両者を沈降槽に供給して処理せしめ、この間に他方
の溶解槽で凝集剤溶液を製造してそのまま同溶液を貯蔵
した状態で待機しておき、その後、前者の溶解槽が空に
なると、弁を切替えて後者の溶解槽より同槽内に貯蔵待
機していた凝集剤溶液を取出して前記同様の処理を引続
いて行ない、また、この間に空になった前者の溶解槽内
で凝集剤溶液を製造して貯蔵待機しておき、後者の溶解
槽が空になれば、再び前者の溶解槽より凝集剤溶液を取
出し、以下上記作用を繰返し行ないながら源濁水を処理
していた。After first producing a flocculant solution in one dissolution tank,
The flocculant solution is sequentially taken out from the same kind and injected into the source turbid water, and both are supplied to the sedimentation tank for treatment. During this time, the flocculant solution is produced in the other dissolution tank and the same solution is stored as it is on standby. Then, when the former dissolving tank becomes empty, the valve is switched to take out the flocculant solution that has been stored in the latter dissolving tank from the latter dissolving tank, and the same process as described above is continued. During this time, a flocculant solution is produced in the former dissolving tank which has become empty and is stored on standby. When the latter dissolving tank is empty, the flocculant solution is again taken out from the former dissolving tank and the above-mentioned effects are carried out. The source turbid water was treated by repeating this process repeatedly.

すなわち、一方の溶解槽から凝集剤溶液を取出している
間に、他方の溶解槽で凝集剤溶液を製造し、これを交互
に行なうことによって、両溶解槽から凝集剤溶液を交互
に取出し、結果的に該溶液を源濁水に連続的に注入しつ
つ処理するようにしていたのである。That is, while the flocculant solution is taken out from one dissolution tank, the flocculant solution is produced in the other dissolution tank, and by doing this alternately, the flocculant solution is taken out from both dissolution tanks alternately, and the result is Therefore, the solution was continuously injected into the source water for treatment.

しかしながら、この従来方法によれば、二基の溶解槽に
それぞれ凝集剤溶液の製造機能と貯蔵機能とをもたさな
ければならず、そのために各槽毎に凝集剤分散器や給水
管および攪拌機を備える必要があり、設備費が非常に高
くつく欠点があった。However, according to this conventional method, each of the two dissolution tanks must have a flocculant solution production function and a storage function, and for this purpose, a flocculant disperser, water supply pipe, and agitator are required for each tank. The disadvantage was that the equipment cost was extremely high.

しかも、二基の溶解槽を横に並べて配置しているため、
スペース上にも問題があり、実用性に乏しいものであっ
た。Moreover, since the two dissolution tanks are placed side by side,
There was also a space problem, and it was not practical.

本考案は、上記の事情に鑑みてなされたもので、その特

下段を凝集剤溶液などの貯蔵を専用とする貯蔵室となし

ようにし、この下段の貯蔵室より前記薬液を順次取出し
ながら、この間に上段の薬液製造室で該薬液を製造した
後、同薬液を下段の貯蔵室に補給できるようにした点に

きるようにしたのである。The present invention was developed in view of the above circumstances, and its characteristics are that the interior of the chemical solution tank is divided into upper and lower chambers, with the upper stage being a chemical solution production room dedicated to the production of coagulant solutions, etc.
The lower tier is used as a storage chamber dedicated to storing flocculant solutions, etc., and the chemical solution produced in the upper chamber can be transferred to the lower chamber and stored, and during this period, the chemical solution is sequentially taken out from the lower storage chamber. After manufacturing the chemical solution in the upper chemical production chamber, the chemical solution can be supplied to the lower storage chamber. In addition, by eliminating the need for one chemical dispersor, water supply pipe, and stirrer for producing chemical solutions such as flocculant solutions, which previously required two units, equipment costs can be saved. .

次に上記装置を用いて砕石プラントより発生する濁水を
処理する場合について説明する。Next, a case will be described in which the above-mentioned apparatus is used to treat turbid water generated from a stone crushing plant.

まず給水管６から薬液製造室３内に所定量の水を供給す

高分子凝集剤粉末を供給しながら攪拌機９にて充分に攪
拌し、同室３内で水に前記凝集前粉末を溶解させること
によって所定の薬液つまり凝集剤溶液を製造する。First, a predetermined amount of water is supplied from the water supply pipe 6 into the chemical manufacturing chamber 3, and the chemical, in this case, polymer flocculant powder, is supplied into the same chamber 3 from the chemical dispersion device 5 and thoroughly stirred with the stirrer 9. In the same chamber 3, the pre-agglomerated powder is dissolved in water to produce a predetermined chemical solution, that is, a flocculant solution.

室４内に流入し、同室４内に貯蔵される。Thereafter, the supply of water and flocculant powder to the chamber 3 and the operation of the stirrer are temporarily stopped, and the valve 12 is opened, so that the flocculant solution produced in the chamber 3 is transferred to the chemical solution storage chamber 4 in the lower chamber. and is stored in the same chamber 4.

その後、空になった上段の薬液製造室３において、前記
弁１２を閉じた状態で再び前記同様の薬液製造作業を開
始する。Thereafter, in the empty upper chemical manufacturing chamber 3, the same chemical manufacturing operation as described above is started again with the valve 12 closed.

is opened and taken out from the chemical extraction pipe 13, and while being injected into the source turbid water through the injection pipe 16 by the operation of the pump 15, the source turbid water and flocculant solution are supplied to the sedimentation tank 18 for treatment, and the clear water is sequentially purified. The slurry is taken out from the take-out pipe 20, and the slurry is taken out sequentially from the slurry take-out pipe 21.
