The present invention relates to a large septic tank for effectively purifying large quantities of by-products generated in large buildings such as livestock, golf courses, and public areas such as stations and terminals.

Conventional septic tanks simply purify by installing a decay chamber, a filtration tank, and an oxidizing plate inside, but these septic tanks are often insufficient in purifying them perfectly. Especially, septic tanks in golf houses and public places where various by-products are generated are purified. There was a flaw in the inability to discharge unclean water.

Therefore, the present invention was devised to solve such a conventional drawback, so that the by-product inflow of double tide tanks can be frequently cleaned of the soil and sand accumulated inside, and the multi-stage decay chamber to improve the purification ability In this case, the sewage purified through the multi-stage decay chamber enables perfect purification by the plastic filter of the pre-filtration tank.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

An inlet 13a is formed at one side of the body 1 and is formed in the same manner as the shape of the tide protection tank 13 having a through hole 1a connected to the first decay chamber 2 so that the cover 12a is upward. It is formed and the inside of the immersion tank 12 to clean the inside, and the body (1) is divided into three, the primary compartment 2 and the secondary decay chamber 3 to the blocking plate (2a) Blocked and connected to the type purification pipe (5), the secondary corruption chamber (3) and the third corruption chamber (4) is blocked by the blocking plate (3a) and a moving hole (4a) is formed on the bottom The lid 10 is formed on the upper side of the first, second and third decayed chambers 2, 3, and 4.

And the preliminary filtration tank (6) is formed with an oxide plate (7) is formed in the upper side of the third corruption chamber 4, the crushed stone (6a) is inserted into the center and the hole is introduced into the lower side, The plastic filter 8 which is wound as if the coil is wound on the oxide plate 7, which is the outer side of the pre-filtration tank 6, and has a plurality of protrusions 8a, and purified to one side of the oxide plate 7. It consists of a large septic tank 11 which comprises the outlet 9 in which wastewater is drained.

The present invention made of such a configuration is the inlet (13a) formed in the sedimentation tank protection container 13 on one side of the body (2) after the dirt or bronze water and its external products are introduced into the soil or sand and solid masses of the sedimentation tank (12). ) Submerged and suspended in the bottom is introduced into the first chamber 2 through the through hole (1a) is decayed.

At this time, the immersion tank 12 opens and lifts the cover 12a at a predetermined time so that the immersion tank can be separated from the protection tank 13 so that the soil or sand accumulated can be removed and then inserted again and cleaned.

And the bronze water and fine dirt decayed in the first decay chamber (2) is first filtered while moving to the second decay chamber (3) through the purification pipe (5), bronze moved to the second decay chamber (3) Water and dirt are transferred to the third corruption chamber 4 through the moving hole 4a. When the bronze water rises in the third corruption chamber 4 and reaches the preliminary filtration tank 6, the hole at the bottom of the preliminary filtration tank 6 is opened. As it rises through, it is filtered secondly by the crushed stone 6a in the pre-filtration tank 6.

In addition, the sewage filtered secondarily through the crushed stone 6a flows through the preliminary filtration tank 6 into the plastic media 8 on the oxidizing plate 7 and to the projection 8a while rotating the plastic media 8. By purifying by being discharged to the outlet (9) to be filtered in the third to improve the removal rate of BOD by the first, second, and third filters, providing almost perfect purification effect and the first, second, third decay chamber (2) ( 3) The odor generated in (4) is naturally decomposed internally and is discharged to the outside by occasionally opening the upper lid 10.

The present invention as described above can be easily cleaned in sand, soil, etc. in the sedimentation tank and completely decomposed and decomposed while passing through the first, second, and third decay chambers, and firstly purified by a purification pipe, and then passed through the crushed stone of the pre-filtration tank. Secondary purification and the third purification while rotating the plastic filter provides the effect of quickly and completely purifying large amounts of sewage while improving the BOD removal rate.
