Embodiment 1

[0041] Embodiment one, as Figure 7 As shown, the cylindrical pool body is provided with a secondary sewage inlet 112, the diameter of the through hole 113 on the first cavity 51, the diameter of the through hole 113 on the second cavity 52, and the diameter of the through hole 113 on the third cavity 53. The ratio between 113 diameters is 3:1:3.

Embodiment 2

[0042] Embodiment two, such as Figure 8 As shown, there is no auxiliary sewage inlet 112 on the cylindrical pool body, the diameter of the through hole 113 on the first cavity 51, the diameter of the through hole 113 on the second cavity 52, the diameter of the through hole 113 on the third cavity 53 The ratio between the diameters of the holes 113 is 3:1:3.

Embodiment 3

[0043] Embodiment three, as Figure 9 As shown, the cylindrical pool body is provided with a secondary sewage inlet 112, the diameter of the through hole 113 on the first cavity 51, the diameter of the through hole 113 on the second cavity 52, and the diameter of the through hole 113 on the third cavity 53. The ratio between 113 diameters is 1:1:1.

Abstract

The invention discloses a three-cavity septic tank. According to the technical scheme, the three-cavity septic tank is characterized by mainly comprising a tank main body, the tank main body comprises an upper tank body and a lower tank body which can in butt joint with each other, the upper tank body and the lower tank body are both made of plastic through integral injection molding, two partition boards are arranged in the tank main body, the partition boards separates internal space defined by the upper tank body and the lower tank body into a first cavity, a second cavity and a third cavity which can allow water flow to sequentially pass through, main sewage inlets allowing sewage to enter are formed in the two sides of the upper tank body, the main sewage inlets communicate the first cavity with the outside, and each main sewage inlet is internally provided with a flange facilitating pipe placement. By means of the upper tank body and the lower tank body which are of plastic structures, cost of the whole septic tank can be greatly saved, the septic tank is convenient to process and can be produced in batches, and sufficient corrosion resistance is achieved. In practical application, openings can be formed in the side faces at multiple angles conveniently, and pipeline connection and laying are facilitated.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a three-compartment septic tank. Background technique [0002] The application of traditional septic tanks has a history of more than 100 years. It was originally used as a feces interception facility to avoid pipeline blockage. It plays an active role in intercepting and settling large particles in sewage, preventing pipeline blockage, and protecting the environment. . The technical principle is the contact mode of sewage and sludge. The deposited sludge is digested and degraded to produce digested gas such as methane, carbon dioxide, and hydrogen sulfide. Due to the flotation of digested gas, the sludge is disturbed, and the disturbing effect of digested gas on sludge can be Let the sludge and biological flora mix more fully, which is helpful for digestion and degradation. However, the sludge at the bottom rises with the digested gas, and after the air bubbles escape...
