難事であり、実現には程遠い感がある。 Various purification devices have been developed as a means to remove wastewater pollution, and it is common to introduce wastewater into these devices, purify it, and then discharge it into a sewer, etc., but it is not possible to purify it until it becomes completely pollution-free. This is quite a difficult task, and it feels like it is far from being realized.

ものである。 In order to solve these problems, sewage that has been purified to a certain extent in a septic tank is not discharged, but is sent to the bottom of a filter tank filled with gravel or soil, and is forced to float by separately pumped air and capillary action. In recent years, a method has been used in which organic matter in sewage is digested by aerobic bacteria and soil bacteria while the water evaporates into the atmosphere. With this method, sewage is not discharged, so there is no wastewater pollution. It is something.

化して菌消化させることができるものである。(Function) Most of the device of the present invention is used by being buried underground, and insufficiently purified wastewater discharged from a septic tank, etc. is guided to a separate adjustment tank, and from this adjustment tank, a pump is pumped. When the air is fed into one end of the contact oxidation tank of the device of the present invention, the air ejected from the numerous fumarole holes provided in the aeration pipe in the contact oxidation tank rises.
The wastewater collides with the bulkhead forming the arched ceiling and bounces around, giving the wastewater a swirling flow that follows the air flow.The wastewater contains many air bubbles and is agitated as it collides with the contact oxidizing material. Through efficient aeration, the organic matter in the wastewater is adsorbed by microorganisms growing on the contact oxidizing material and oxidized and decomposed.
This method activates the action of aerobic bacteria to digest organic matter in wastewater. Wastewater that is effectively purified in this way increases the amount of dissolved oxygen, contains air bubbles, increases elasticity, and accumulates sufficient air. The liquid enters the upper filtration evaporation tank from the inlet and penetrates into the gravel and permeable soil by capillary action, and the air ejected from the fumarole of the fumarole pipe installed in this filtration evaporation tank rises and becomes sewage. The water is forced to evaporate from the surface of the filtration evaporation tank by pushing up the water from the surface of the filtration evaporation tank in conjunction with accumulated heat such as solar energy and geothermal heat. Furthermore, it is highly aerated, oxidized, adsorbed, and decomposed, and can activate and digest soil bacteria living in the filter layer.

たものである。 In addition, sludge that may settle at the bottom of the contact oxidation tank over a long period of time can be taken out of the contact oxidation tank by opening the outlet of the sludge return pipe.
そもそも、水が最も蒸発し易いのは、蒸溜水で
あり、汚水を効果的に蒸発させるためには、でき
るだけ高度に浄化することが条件となる。 In the first place, distilled water is the type of water that evaporates most easily, and in order to effectively evaporate wastewater, it is necessary to purify it to the highest possible level.
従つて汚水処理装置の浄化機能が良ければ効率
よく蒸発するから蒸発面積は小さくてよいことに
なる。 Therefore, if the purification function of the sewage treatment device is good, the evaporation area can be small because it evaporates efficiently.
この点、従来の蒸発処理方式は土壌濾過を主体
としているため浄化が不十分で広い蒸発面積を必
要としていたが、本発明では土壌濾過の前に接触
酸化処理を行うようにしたことにより、汚水を高
度に浄化した後土壌濾過させるため蒸発を著しく
促進し、上昇エアーによる通気性の増加で蒸発面
積を小さくすることができるものである。 In this regard, conventional evaporation treatment methods mainly involve soil filtration, which results in insufficient purification and requires a large evaporation area.However, in the present invention, contact oxidation treatment is performed before soil filtration, making it possible to improve wastewater After highly purified water is filtered through the soil, evaporation is significantly accelerated, and the increased air permeability due to rising air reduces the evaporation area.
実験によると、従来の濾過のみのものが汚水１
m3を蒸発させるのに平均22m2の蒸発面積を必要と
したが、本発明では平均18m2で済み、面積比約20
％の減少となつた。 According to experiments, conventional filtration alone reduces wastewater by 1
An average evaporation area of 22 m 2 was required to evaporate 3 m 3 , but with the present invention, an average evaporation area of 18 m 2 is required, and the area ratio is approximately 20 m 2 .

Air is blown out from. Then, the sewage in the tank is agitated by the air jet, and the air bounces off the ceiling formed by the arch-shaped partition wall 2 and rises again, giving the sewage a swirling flow that follows the air flow, during which catalytic oxidation occurs. The organic matter in the sewage is adsorbed by the contact oxidizing material 6 by colliding with the material 6 and aerated in a complicated flow, oxidizing and decomposing it, activating the aerobic bacteria living in the tank, and using the organic matter as food. It is something to be digested.

俟つて強性蒸発させるものである。 There are various types of aerobic bacteria, and they have the property of being able to digest certain types of organic matter particularly well. Different types of aerobic bacteria are arranged in each compartment divided by 5, and sewage enters from the sewage inlet 9 and passes through each compartment sequentially, thereby efficiently digesting many types of organic matter. The sewage that has been effectively purified in this way enters the upper filtration and evaporation tank 3 through the water inlet 10 while still containing some organic matter, and permeates into the granular materials 7 and permeable soil 8 by capillary action. The air that floats up and blows out from the fumarole hole 13a of the fumarole pipe 13 helps the infiltration of wastewater, and also causes organic matter to be aerated and adsorbed to the particulate matter 7 and the permeable soil 8, where it is oxidized and decomposed, and becomes soil bacteria. It activates and digests water, and intensely evaporates water by combining the heating effect of solar heat and geothermal heat.

It is something.
