Practical septic tank

Abstract

The invention discloses a practical septic tank. According to the practical septic tank, a dredging well (11) which is lower than the bottom of a cylinder (1) is arranged below a septic tank; the bottom depth of the dredging well (11) is 10cm or greater; as the dredging well (11) is lower than the bottom of the cylinder (1), a sucking tube of a fecal suction truck can stretch into the dredging well (11) to relatively easily suck out night soil inside the septic tank completely; a parallel line (5) parallel to the top surface of the cylinder (1) is arranged on the septic tank; a lever ruler (7) is moveably hinged with a mounting column (6) of the cylinder (1), and then the levelness of the septic tank can be easily adjusted; a vertical needle (10) is moveably connected with the mounting column (9) on an end surface (8) of the cylinder (1) of the septic tank, so that the perpendicularity of the septic tank can be adjusted, a glass fiber reinforced plastic septic tank can be debugged and mounted rapidly with good levelness and perpendicularity, and the practical septic tank is simple in structure, good in use effect and very easy to implement and popularize.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic septic tank, in particular to a new practical septic tank. Background technique [0002] FRP septic tank is a three-format cylindrical sewage treatment overall structure that is connected with the first-level anaerobic tank, the second-level anaerobic tank, and the third-level clarification tank. It is usually equipped with inlet and outlet pipes and dung residue Compared with the traditional brick-concrete septic tank, it has the advantages of tightness and no leakage, high compressive strength, and long service life of acid and alkali resistance. However, in the process of cleaning the septic tank, more The suction and removal of feces in the first-level anaerobic tank must reach 90%. However, the bottom of the current cylindrical fiberglass septic tank is too straight, so it is not easy to use a fecal suction truck to suck the feces. The suction is clean; and as the Chinese patent number is ...

[0002] FRP septic tank is a three-format cylindrical sewage treatment overall structure that is connected with the first-level anaerobic tank, the second-level anaerobic tank, and the third-level clarification tank. It is usually equipped with inlet and outlet pipes and dung residue Compared with the traditional brick-concrete septic tank, it has the advantages of tightness and no leakage, high compressive strength, and long service life of acid and alkali resistance. However, in the process of cleaning the septic tank, more The suction and removal of feces in the first-level anaerobic tank must reach 90%. However, the bottom of the current cylindrical fiberglass septic tank is too straight, so it is not easy to use a fecal suction truck to suck the feces. The suction is clean; and as the Chinese patent number is 2016204663802, and the invention name is "glass reinforced plastic septic tank", a level is provided on the outer wall of the septic tank cylinder, which is convenient for the staff to observe and adjust whether the two ends of the septic tank are level, but, The process of using a level to adjust whether the septic tank is horizontal is complicated and slow. In addition, the level has no function of adjusting the vertical state of the septic tank; this will easily lead to passive work.
