Description

本発明は、薬剤を収容可能であり、且つ移流する被処理水が流入し得る流入口と、前記被処理水が流出し得る流出口とをその周部に備えて、流入した前記被処理水と収容された前記薬剤とを接触させ得る薬筒を、複数の処理槽間を前記被処理水が移流する移流部に取り付ける浄化槽の薬筒取付け構造に関する。   The present invention comprises an inlet that can contain a chemical and into which the treated water to be transferred can flow in, and an outlet from which the treated water can flow out. The present invention relates to a medicine cylinder mounting structure for a septic tank in which a medicine cylinder that can be brought into contact with the medicine contained therein is attached to a convection section to which the water to be treated circulates between a plurality of treatment tanks.

従来の一般的な浄化槽には、上流側から第１嫌気濾床槽、第２嫌気濾床槽、接触曝気槽、沈殿槽、及び消毒槽等が順に配置されている。
被処理水（し尿、生活雑排水等）は、原水流入部から流入し、以降、第１嫌気濾床槽、第２嫌気濾床槽、接触曝気槽において順次浄化処理された後、沈殿槽に流入する。
沈殿槽に流入した被処理水は、汚泥が沈殿分離され、その上澄み液がオーバフローして移流部を流れ、移流部に設置された薬筒内の消毒剤と接触して消毒された後、消毒槽を経て、放流口から放流される。
被処理水を消毒剤で消毒する際、消毒剤（例えば、塩素剤等）の溶解量が多過ぎると、被処理水中に残留する消毒剤量も多くなり、そのまま放流された場合、発癌性物質のトリハロメタン等が生成される危険性が増大して自然環境を害することとなる。また、消毒剤の溶解量が少なすぎても、被処理水の消毒が不十分となり、河川等を汚し、自然環境を害することとなる。
従って、浄化槽においては、被処理水中に適正な量の消毒剤を溶解させる必要がある。
一方、被処理水の汚れ度合いや、季節等（微生物が繁殖し易い夏場は、微生物の繁殖し難い冬場よりも、消毒剤を多めに溶解させる必要がある）によっても、消毒剤溶解量の適正値が変化し得るため、随時、その溶解量を調節し得るような構成であることが要求される。
そこで、従来の浄化槽においては、内筒と外筒の二重筒構造を有し、且つその下端部に、被処理水の流入口と流出口とが設けられており、内筒を外筒に対して周方向に回転させることにより流入口と流出口の開口面積を調節し得る薬筒（即ち、この薬筒は、薬筒内への被処理水の流入量を調節することによって、被処理水に対する消毒剤の溶解量を調節することができる）を、沈殿槽から消毒槽にわたる被処理水の移流部に設置する構成が提案されている。（特許文献１参照） In a conventional general septic tank, a first anaerobic filter bed tank, a second anaerobic filter bed tank, a contact aeration tank, a precipitation tank, a disinfection tank, and the like are sequentially arranged from the upstream side.
To-be-treated water (human waste, domestic wastewater, etc.) flows from the raw water inflow section, and after being sequentially purified in the first anaerobic filter bed tank, the second anaerobic filter bed tank, and the contact aeration tank, Inflow.
The treated water that has flowed into the settling tank is sludge settled and separated, the supernatant liquid overflows and flows through the advection section, and is disinfected by contacting with the disinfectant in the cartridge installed in the advection section. It is discharged from the outlet through the tank.
When disinfecting water to be treated with a disinfectant, if the amount of disinfectant (for example, chlorine agent) is too large, the amount of disinfectant remaining in the water to be treated will increase, and if released as it is, carcinogenic substances The risk of the generation of trihalomethane and the like will increase and harm the natural environment. In addition, even if the amount of disinfectant dissolved is too small, disinfection of the water to be treated becomes insufficient, polluting rivers and the like and harming the natural environment.
Therefore, in the septic tank, it is necessary to dissolve an appropriate amount of the disinfectant in the water to be treated.
On the other hand, depending on the degree of contamination of the water to be treated and the season, etc. (in the summertime when microorganisms are easy to propagate, it is necessary to dissolve more disinfectant than in winter when microorganisms are difficult to propagate). Since the value can change, it is required to be configured so that the amount of dissolution can be adjusted at any time.
Therefore, the conventional septic tank has a double cylinder structure of an inner cylinder and an outer cylinder, and an inlet and an outlet of water to be treated are provided at the lower end thereof, and the inner cylinder is used as an outer cylinder. On the other hand, by rotating in the circumferential direction, a medicine cylinder that can adjust the opening area of the inlet and outlet (that is, this medicine cylinder is treated by adjusting the amount of water to be treated into the medicine cylinder. A configuration has been proposed in which the amount of disinfectant dissolved in water can be adjusted) is installed in the transfer section of the water to be treated from the settling tank to the disinfecting tank.

しかしながら、上述の従来の浄化槽においては、被処理水に対する消毒剤の溶解量を調節するたびに、作業者は、薬筒を、移流部からいちいち取り外さなければならなかった（即ち、薬筒を一旦取り外してからでなければ、その内筒を外筒に対して周方向に回転させることができなかった）。さらに、その際、手が消毒剤や被処理水で汚れるため、予めゴム手袋等をはめなければならず、非常に面倒な作業であった。
本発明は、上記実情に鑑みてなされたものであって、被処理水に対する消毒剤の溶解量を、作業者の手等を汚すことなく容易に調節することができる浄化槽の薬筒取付け構造を提供するものである。 However, in the above-described conventional septic tank, each time the amount of the disinfectant dissolved in the water to be treated is adjusted, the operator has to remove the medicine cylinder from the advection section (that is, once the medicine cylinder is removed). Unless it was removed, the inner cylinder could not be rotated in the circumferential direction with respect to the outer cylinder). Further, at that time, the hands become dirty with the disinfectant and the water to be treated, so it is necessary to put on rubber gloves in advance, which is a very troublesome work.

By doing so, the amount of the disinfectant dissolved in the water to be treated can be adjusted.
That is, when the operator adjusts the amount of the disinfectant dissolved in the water to be treated, it is not necessary to remove the medicine cylinder from the advection section one by one, and the operator may adhere to the water to be treated and the disinfectant. Since it is possible to rotate the barrel by grasping the upper end portion of a small number of barrels, it is difficult for the operator's hands to get dirty, and it is not necessary to wear gloves or the like.

本発明の第３特徴構成は、前記流入量調整手段は、前記移流部における前記被処理水の流れに対する前記流入口の向きを変更可能とする構成からなる点にある。

図１１は、流入口２０及び流出口２１の開度を全開としたときの様子である。このとき、エアリフトポンプ１６によって揚水される被処理水Ｗのほとんどが、薬筒１４内に流入し得るため（薬筒１４内に流入する被処理水量が最大となる）、被処理水Ｗに対する消毒剤の溶解量も最大となる。
図１２は、流入口２０及び流出口２１の開度を半開としたときの様子である。このとき、エアリフトポンプ１６によって揚水される被処理水Ｗの一部が、薬筒１４内に流入し、残りは、壁部２２に設けられた落水口２２ｂより落水して消毒槽６内に流入するため、被処理水Ｗに対する消毒剤の溶解量も、上記図１１の全開の場合と比べて小さくなる。
図１３は、流入口２０及び流出口２１の開度を全閉としたときの様子である。このとき、薬筒１４に流入する被処理水量がゼロとなり、被処理水Ｗは、壁部２２に設けられた落水口２２ｂより落水して消毒槽６内に流入するため、被処理水Ｗに対する消毒剤の溶解量はゼロとなる。 FIGS. 11-13 has shown the mode which rotates the circumference of the cylinder axis in the state installed in the installation part 17b, and adjusts the opening degree of the inflow port 20 and the outflow port 21 in FIG. . 11 to 13, (a) is a perspective view of the medicine cylinder 14 and the installation part 17, and (b) is a plan sectional view of the medicine cylinder 14 and the installation part 17.
FIG. 11 shows a state where the opening degree of the inlet 20 and the outlet 21 is fully opened. At this time, most of the water to be treated W pumped by the air lift pump 16 can flow into the medicine cylinder 14 (the amount of water to be treated flowing into the medicine cylinder 14 is maximized). The amount of agent dissolved is also maximized.
FIG. 12 shows a state where the opening degree of the inlet 20 and the outlet 21 is half open. At this time, a part of the water W to be pumped by the air lift pump 16 flows into the medicine cylinder 14, and the rest flows into the disinfection tank 6 by dropping from the water outlet 22 b provided in the wall portion 22. For this reason, the amount of the disinfectant dissolved in the water to be treated W is also smaller than in the fully opened case of FIG.
FIG. 13 shows a state in which the openings of the inlet 20 and the outlet 21 are fully closed. At this time, the amount of water to be treated flowing into the medicine cylinder 14 becomes zero, and the water to be treated W falls from the water outlet 22b provided in the wall portion 22 and flows into the disinfection tank 6, so The amount of disinfectant dissolved is zero.

尚、図６〜図８、図１０〜図１３に示されるように、筒本体部１８の下部外周面には、その直径方向の相対する位置に、２つの突起部２３が設けられており、壁部の被係止部２２ａと共に、ストッパー機構を構成している。即ち、薬筒１４を回転操作する際、筒本体部の突起部２３が、壁部の被係止部２２ａにて係止することによって、薬筒１４の回転操作が、流入口２０の開度が全開（図１１）若しくは全閉（図１３）である位置（一定の回転角位置）で規制されるように構成されている。   As shown in FIGS. 6 to 8 and FIGS. 10 to 13, two projecting portions 23 are provided on the lower outer peripheral surface of the cylinder main body portion 18 at positions opposed to each other in the diameter direction. A stopper mechanism is formed together with the locked portion 22a of the wall portion. That is, when the barrel 14 is rotated, the projection 23 of the barrel main body is locked by the locked portion 22a of the wall, so that the rotation of the barrel 14 can be controlled by the opening degree of the inlet 20. Is regulated at a position (a constant rotation angle position) that is fully open (FIG. 11) or fully closed (FIG. 13).
