【発明の詳細な説明】
本発明は、山間・丘陵地・或いは狭隘沿海地にある生活
系排水処理に関し、特に比較的過疎地或いは観光地に適
したそれに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to domestic wastewater treatment in mountainous, hilly areas, or narrow coastal areas, and particularly to treatment suitable for relatively depopulated areas or tourist areas.
最近、山間観光地の環境汚染防止について、特に上水道
水源の汚濁防止及び下流域での水系の総量規制の見地か
ら重大な関心が持たれている。Recently, there has been a great deal of interest in the prevention of environmental pollution in mountain tourist areas, especially from the standpoint of preventing pollution of water supply water sources and regulating the total amount of water in downstream areas.
とりわけ湖沼のある観光地では富栄養化による水質汚濁
が進行し、景勝地としての美観価値低下、水産漁業への
打撃、飲料水としての利用不能化等の問題が発生してい
る。In particular, in tourist areas with lakes and marshes, water pollution due to eutrophication is progressing, causing problems such as a decline in the aesthetic value of scenic spots, damage to fisheries, and the inability to use drinking water.
この対応策として、公共下水道・流域下水道・特定環境
下水道の如き下水道事業の普及対象地域はともかくとし
て、この対象となり得ない豪雪・山間その他の過疎地に
おいては、処理設備計画中の所もあるが、従来法設備で
は厖大な建設費・運転費を要し、その資金負担が地方自
治体財政を著しく圧迫するため問題となっているのが現
状である。As a countermeasure for this, apart from areas targeted for the spread of sewage works such as public sewage systems, regional sewage systems, and designated environmental sewage systems, some places are currently planning treatment facilities in areas with heavy snowfall, mountains, and other depopulated areas that cannot be targeted. The current situation is that conventional equipment requires enormous construction and operating costs, and the financial burden puts significant pressure on local government finances, creating a problem.
この対策としては、公知の移動式生活系排水処理設備ま
たは地下埋設式の排水処理設備がある。As a countermeasure against this problem, there are known mobile domestic wastewater treatment equipment or underground wastewater treatment equipment.
しかし、移動式では比較的処理量の多い場合には設置ス
ペース・運搬費用等の面から難点があり、特定キャンプ
地の如く特別の条件に合致したときのみに使用できるも
のである。However, the mobile type has disadvantages in terms of installation space and transportation costs when processing a relatively large amount, and can only be used when special conditions are met, such as at a specific campsite.
即ち、これは年間を通じ、特に寒冷期及び豪雪期を通じ
て使用できるものではない。That is, it cannot be used throughout the year, especially during periods of cold weather and heavy snowfall.
一般に山間観光地では冬期寒冷気候地或いは豪雪地が多
く、気湿の低下は厳しい上、観光人口が例えばスキー場
の如く特定期間に集中し、逆に皆無に等しい期間もある
ことを特徴とする。In general, mountain tourist areas often have cold climates or areas with heavy snowfall in the winter, where the drop in air humidity is severe, and the tourist population is concentrated during certain periods, such as at ski resorts, and conversely there are periods when there are no tourists at all. .
このような気温及び処理負荷の急変動に耐えることがで
き、且つ山間急傾地に設定可能であり、また観光上美観
も害うことなく自然環境を破壊しない排水設備の開発が
望まれている。It is desired to develop drainage equipment that can withstand such sudden changes in temperature and processing load, can be installed in steep mountainous areas, and does not harm the aesthetics of tourism or destroy the natural environment. .
即ち、生物分解による生活排水処理の最大の欠点は、水
温低下による微生物機能の低下である。That is, the biggest drawback of domestic wastewater treatment using biodegradation is the decline in microbial function due to a drop in water temperature.
特（こ山間地等において冬期の気温及び水温の低下（こ
より排水処理が不完全化することは従来法において一般
的に不可避である。Especially in mountainous areas, it is generally unavoidable in conventional methods that wastewater treatment becomes incomplete due to the drop in air and water temperatures during the winter.
地下埋設式は、移動式や地上式よりはや５温度変化に適
応力があるおは言え、例えば駐車場の如き広大な平地を
必要とするものであり山間急傾地には建設不適当な場合
が多い上、地表温度一外気渦の影響をなおうけ易く、冬
期の温度低下は避けられない。Although the underground type is more adaptable to temperature changes than the mobile or above-ground type, it requires a large area of flat land, such as a parking lot, and is not suitable for construction on steep slopes in the mountains. In addition, the ground surface temperature is susceptible to the influence of outside air vortices, and a drop in temperature in winter is unavoidable.
叙上の如く従来法においては、冬期の処理不安定化が山
間地においては避けられず排水の発生源における完全処
理・還流が困難であるという本質的欠点を有する。As mentioned above, the conventional method has an essential drawback in that treatment becomes unstable in winter in mountainous areas and complete treatment and reflux of wastewater at the source is difficult.
本発明は、以上の如き従来法の欠点を除去する新規な排
水処理設備を提供することを目的とする。An object of the present invention is to provide a new wastewater treatment facility that eliminates the drawbacks of the conventional methods as described above.
即ち、本発明は、生物処理要素を有する傾斜ずい道を処
理空間とすることを特徴とする排水処理設備を提供する

においては一定の岩盤湿度により自然流通空気の気温が
調節されるという利点がある。In this respect, the buried type is directly supplied with outside air on the ground surface, so it is easily affected by fluctuations in water temperature due to the rise and fall of air temperature, but the present invention has the advantage that the temperature of naturally circulating air can be adjusted by a constant rock humidity. be.
（３）傾斜地・出間地・壁地にも設置できる。(3) Can be installed on sloping land, land on a slope, and on walled land.
従来の設備では、このような需要を満たすことができな

置する場合が殆んどであり、地下水湧出防水工事が必要
となり、防水工事のための薬液注入等による地下水汚染
や、地下水脈の変動等の問題が発生し易い。In most cases, the buried type is installed in low-lying areas in mountainous areas, especially near the surface of lakes, and requires waterproofing work for groundwater gushing, which can lead to groundwater contamination due to chemical injection for waterproofing work, fluctuations in groundwater veins, etc. problems are likely to occur.
（７）岩盤が良好なとき、ずい道の長手方向に隔壁を設
け、岩盤面の止水処理を行う程度でもよく、設備費が節

特に小規模な埋設式ではマンホールが用いられるのが一
般的である。In particular, manholes are commonly used for small-scale underground installations.
（１１）換気孔の配設により悪臭は高所へ排出できるの
で、悪臭公害等を発生しない。(11) Odors can be discharged to high places by providing ventilation holes, so odor pollution does not occur.
