As a preference, there are several annular grooves, which are evenly distributed along the axial direction of the cylinder;

As a preference, the pool body is composed of an upper pool body and a lower pool body. A flange is provided at the connection between the upper pool body and the lower pool body, and fastening bolts are arranged on the flange side. Between the upper pool body and the lower pool body Fasten the connection by fastening bolts;

As a preference, the end caps at the left and right ends of the pool body are respectively provided with a water inlet and a water outlet;

As a preference, the inner surface of the end cap is provided with a corrugated plate-shaped groove that is the same as the end surface of the separator;

As a preference, a reinforcement block is provided between the flange and the pool body;

Preferably, the reinforcing block is a trapezoidal reinforcing rib;

As a preference, the gap between the upper tank body and the lower tank body, and the connection between the annular groove and the partition are all filled with a resin cement layer for sealing and fixing;

Preferably, the fastening bolts are covered with resin cement sleeves.

Compared with the prior art, the utility model has the advantages that: through the annular grooves on the upper pool body and the lower pool body, as well as the corrugated plate-shaped grooves on the partition plate and the end cover, the circular arc formed in the closed pool body corrugated belt. Slow down the washing speed of sewage. Can effectively adsorb anaerobic bacteria. It provides the necessary conditions for the oxygenation of the anaerobic bacteria, so that the harmful microorganisms in the sewage can fully contact and ferment the anaerobic bacteria. From the water inlet to the water outlet, the pool body is divided into one-level and one-level chambers by partition boards for reaction, so as to achieve the purpose of sewage treatment and purification after discharge.

Detailed ways

The utility model will be further described below.

Embodiment: Referring to Fig. 1, a high-strength FRP septic tank includes a cylindrical tank body 1, and end caps 3 are provided at the left and right ends of the tank body 1, and along the inner wall of the tank body 1 The circumferential direction is provided with an annular groove 2, which not only greatly enhances the overall rigidity and strength of the septic tank body, but also forms a complete installation ring for the installation of the partition plate 7. The annular groove 2 There are several, and they are evenly spaced along the axial direction of the cylinder body. A partition 7 is vertically arranged in the pool body 1. The partition 7 is a corrugated plate. The groove shape of the annular groove 2 is the same as The edge shape of the partition 7 matches, and the partition 7 is installed and fixed in the pool body 1 through the annular groove 2; the inner surface of the end cover 3 is provided with a corrugated plate-like groove with the same end surface of the partition 7; The new circular arc-shaped corrugated belt formed in the airtight pool body 1 slows down The scouring speed of sewage can effectively absorb anaerobic bacteria and will not be washed away by sewage, so that the most effective way for dirt and sewage to fully contact with anaerobic bacteria to produce biochemical reactions is to provide oxygen for anaerobic flora The necessary conditions are met so that the harmful microorganisms in the sewage can fully contact and ferment the anaerobic bacteria. From the water inlet 4 to the water outlet 5, the pool body 1 is divided into one-level and one-level chambers for reaction by using partitions 7, so as to achieve the purpose of sewage treatment and discharge after purification.

Described pool body 1 is made up of upper pool body 8 and lower pool body 9, and upper pool body 8 and lower pool body 9 joints are provided with flange edge, and flange edge is provided with fastening bolt 12, and described upper pool body 8 is connected with lower pool body 9.
