[0025] As shown in Figs. 1 to 4 The utility model provides a kind of sewage treatment horizontal tube sedimentation system, including sedimentation tank 4 and the hopper 14 of setting at the bottom of sedimentation tank, the sedimentation tank is divided into water inlet cavity 5, water distribution cavity 6, sedimentation cavity 11 and water outlet cavity 12 by partition 8, the water hole 9 that makes water flow sequentially turns back and flows through water inlet cavity, water distribution cavity, sedimentation cavity and water outlet cavity is opened on the partition, at least one layer of water distribution grid 7 is provided in water distribution cavity.

[0026] In the embodiment, the water distribution cavity is divided into a plurality of water distribution chambers by the partition, the water hole that makes water flow sequentially turns back and flows through the plurality of water distribution chambers is opened on the partition, and at least one layer of water distribution grid is provided in the water distribution chamber. Preferably, a plurality of layers of water distribution grids are provided in the water distribution chamber in the vertical direction. In this way, the water distribution time can be prolonged, and the water distribution effect can be improved. The water distribution grid functions to further mix the water outlet from the water inlet cavity with the flocculant, to make the flocculation reaction more sufficient, to make the particles further grow, and to create better conditions for subsequent sedimentation and separation.

[0027] When working, the sewage sequentially turns back and flows through the water inlet cavity, the water distribution cavity, the sedimentation cavity and the water outlet cavity, uniformly distributes water through the water distribution cavity, can make the sewage and the flocculant fully mix, improves the flocculation effect, speeds up the particle coagulation speed, and thus improves the sedimentation efficiency and effect. In specific implementation, the water outlet cavity is connected with a water outlet pipe 13, and the purified clean water can be discharged through the water outlet pipe; the hopper is connected with a sludge discharge pipe 15 with a sludge discharge valve, and the sludge is discharged from the sludge discharge pipe.

The inner wall of the stirring barrel is provided with the cyclone plate 2. In the specific implementation, the stirring barrel is arranged in the water inlet cavity, the top of the stirring barrel is higher than the top of the water inlet cavity, the sewage enters the stirring barrel through the water inlet pipe in a tangential direction, and then flows into the water inlet cavity from the bottom of the stirring barrel. The sewage is stirred by the stirring barrel, and the flow guide effect of the cyclone plate can enhance the water flow stirring and promote the preliminary mixing of the sewage and the flocculating agent, so that the suspended particles collide and gather with each other.

[0029] As a further improvement of the above technical solution, the sedimentation cavity is paved with multiple layers of horizontal sedimentation pipes 10, and adjacent layers of horizontal sedimentation pipes are arranged staggered in the paving direction. The bottom of the horizontal sedimentation pipe is open, and the horizontal sedimentation pipe is a rhombic pipe. When the sewage flows in the rhombic pipe, the sludge particles are precipitated downward under the action of gravity due to the density difference of the sludge and water, and are discharged through the bottom opening of the rhombic pipe.

[0032] High separation efficiency: the structure of the horizontal sedimentation pipe arranged in an up-down staggered array increases the sedimentation area and shortens the particle sedimentation distance, effectively improving the sludge and water separation efficiency, and thus improving the sewage treatment efficiency.

[0033] Compact structure: the overall structure of the present sedimentation system is relatively compact, and occupies a small space, which can save the occupied area in actual engineering application and facilitate installation and arrangement.
