この発明は土壌浸透式廃水処理施設における地
中埋設散水管の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in underground sprinkler pipes in soil infiltration type wastewater treatment facilities.
土壌のもつ浄化能力は大きく、有機物や固形物
だけでなく、窒素やリン等の栄養塩の除去効果も
あるので、最近では廃水を土壌中に浸透させるこ
とによつて廃水の高度処理を行おうという動きが
盛んになつてきている。しかし、土壌浸透処理に
おいては、処理水を地下に進透させるため処理水
の水質のチエツクが困難であり、地下水汚染の防
止という観点からも、土壌の浄化能力以上の廃水
の散水を行わないようにしなければならない。 Soil has a great purification ability, and has the effect of removing not only organic matter and solid matter, but also nutrients such as nitrogen and phosphorus.Recently, advanced treatment of wastewater is being carried out by infiltrating wastewater into the soil. This movement is gaining momentum. However, in soil infiltration treatment, it is difficult to check the quality of the treated water because it penetrates underground, and from the perspective of preventing groundwater contamination, it is recommended not to sprinkle wastewater in excess of the soil's purification capacity. must be done.
土壌浸透処理において、散水管を土壌中に埋設
して地中で散水する方法は、美観上、衛生上好ま
しい方法であるが、反面、散水管が地中にあるた
め散水状態の確認ができず、思わぬ不均一散水が
行われ、そのため一部分だけに散水がかたより、
廃水の浄化が十分に行われないという危険性もあ
る。 In soil infiltration treatment, burying water pipes in the soil and spraying water underground is a preferable method from an aesthetic and sanitary standpoint, but on the other hand, since the water pipes are underground, it is not possible to check the watering status. , Unexpected uneven watering occurs, and as a result, watering is uneven in only one part.
There is also the risk that wastewater will not be purified sufficiently.
本発明はこの地中埋設方式の廃水散水装置の問
題点を解決し汚水の土壌中への均等散水を可能に
したものである。 The present invention solves the problems of this underground type wastewater sprinkler and makes it possible to uniformly sprinkle wastewater into the soil.
以下、本発明を図面に基づいて説明する。 Hereinafter, the present invention will be explained based on the drawings.
１は土壌中に埋設されている網目パイプで、そ
の上端には穴あき塩ビ管２が内接して取り付けら
れている。 1 is a mesh pipe buried in the soil, and a perforated PVC pipe 2 is attached to the upper end thereof.
穴あき塩ビ管２は上半分にだけ穴を設けてあり
廃水の通り道となつている。また穴あき塩ビ管２
の穴径は、廃水による目詰りがおこらない範囲内
でできるだけ小さくされている。 The perforated PVC pipe 2 has holes only in the upper half, and serves as a passage for wastewater. Also perforated PVC pipe 2
The hole diameter is made as small as possible without clogging with wastewater.
一旦貯留槽３に貯えられた廃水は、水中ポンプ
４によつて配水槽５を通つて穴あき塩ビ管２に送
水されるが、穴あき塩ビ管２の穴径が小さいた
め、すぐに穴あき塩ビ管２内は満水となり、さら
に、配水槽５の水位が上昇する。穴あき塩ビ管２
内の廃水は、この水位差によつて網目パイプ１内
に勢いよく散水され、これによりほぼ均等散水が
達成される。次に、網目パイプ１内に散水された
廃水は、通常、土壌の浸透速度に比べて散水速度
の方がかなり大きいので、一旦網目パイプ１内に
たまることになり、この網目パイプ１内にたまつ
た水は徐々に土壌中を広がりながら浸透し、土壌
による浄化を受ける。 Once the wastewater is stored in the storage tank 3, it is sent to the perforated PVC pipe 2 through the water distribution tank 5 by the submersible pump 4, but since the hole diameter of the perforated PVC pipe 2 is small, it quickly becomes perforated. The inside of the PVC pipe 2 becomes full of water, and the water level in the water distribution tank 5 further rises. Perforated PVC pipe 2
The waste water inside the mesh pipe 1 is sprayed vigorously into the mesh pipe 1 due to this water level difference, thereby achieving almost uniform water spraying. Next, the waste water sprinkled into the mesh pipe 1 will accumulate inside the mesh pipe 1 once, because the watering speed is usually much higher than the soil penetration speed. The water gradually permeates through the soil and is purified by the soil.
このように、本装置では、穴あき塩ビ管２での
水位差における散水と網目パイプ１内に一旦廃水
をためたのちの土壌への散水という二つの操作を
組み合わせることにより土壌への均等散水を確実
なものとしている。 In this way, this device can evenly water the soil by combining two operations: watering based on the water level difference in the perforated PVC pipe 2 and watering the soil after collecting wastewater in the mesh pipe 1. It is made certain.
なお、水中ポンプ４によつて一回に散水する量
は、土壌の浸透性を考慮する必要があるが、通常
は網目パイプ１内に水が充満する程度とする。ま
た土壌がシルトのように粒径が小さい場合は、土
壌粒子の網目パイプ１内への流入が考えられる
が、第１図のごとく網目パイプ１の回りに砂６な
どを敷いて土壌粒子の流入を防ぐことができる。 Note that the amount of water sprinkled at one time by the submersible pump 4 needs to take into account the permeability of the soil, but is usually set to an amount that fills the mesh pipe 1 with water. In addition, if the soil has small particle size such as silt, it is possible that the soil particles will flow into the mesh pipe 1, but as shown in Figure 1, sand 6 or the like is spread around the mesh pipe 1 to prevent the soil particles from flowing in. can be prevented.
