Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, the sewage treatment device of the present invention includes a sewage treatment device main body 1, the water inlet 2 is located at the top of the sewage treatment device main body 1, and two crushing rod groups are arranged at the water inlet 2, and each crushing rod group includes several crushing rod groups. rod 3, figure 1 It is shown in the figure that each breaker bar group includes two layers of five breaker bars each, a total of 10 breaker bars, and the breaker bars of the two breaker bar groups are arranged crosswise. Each group of broken rods is driven to rotate by the rotating shaft 4, and the rotating shaft 4 is supported by the first support rod. The motor 7 drives the rotating shaft 4 to rotate through the transmission shaft 6 under the transmission of two bevel gears 24 . The motor 7 drives the vertical main shaft 10 to rotate through two outer bevel gears. From top to bottom, the main shaft 10 is first fixedly conn...

Embodiment 2

[0031] Embodiment 2: The same structure as other main parts of Embodiment 1, the difference between Embodiment 2 and Embodiment 1 is that the spiral disk 15 on the main shaft 10 of Embodiment 2 is a double-layer structure, as figure 2 As shown, the spiral disk 15 has a double-layer structure, and the distance between the two layers of spiral disks 15 is 20mm. The inventors of the present invention unexpectedly found that setting the spiral discs into a double-layer structure can greatly improve the sewage treatment effect, because a large number of suspended microorganisms are gathered in the space between the two layers of spiral discs, which improves the Microbial concentration per unit volume, thus improving the sewage treatment effect per unit time.

Embodiment 3

[0032] Embodiment 3: The structure of other main parts of Embodiment 1 is the same as that of Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the surface of the spiral disk 15 has uniformly arranged grooves, and the groove patterns are arranged at intervals in a fan-shaped manner. image 3 The apex angle of the projection on the horizontal plane of the middle sector is 60°, and the angle between the projections on the horizontal plane of the grooves on two adjacent sector-shaped disks is 90°. The inventors found that by setting grooves on the spiral disc 15, the grooves in adjacent areas are connected at a certain angle, which increases the contact area between sewage and biofilm on the one hand, and on the other hand, the groove structure promotes the separation of sewage. Flow, avoiding the formation of sewage dead zone.

Abstract

The invention belongs to the field of sewage disposal and relates to a sewage disposal device. The device comprises a sewage disposal device main body (1), a crushing rod group, a main shaft (10), a separation turntable (9), spiral discs (15), water outlet pipes (19), first blades (20), second blades (17) and other structures. The sewage disposal device can improve the sewage purification efficiency, increase the volume load of a biological turntable, simplify a turntable driving device, and greatly reduce the energy consumption.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a sewage treatment device. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter, such as protein, carbohydrate, fat, ammonia nitrogen, etc. The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens in sewage multiply by using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge. [0003] There are many means of sewage treatment, such as gravity sedimentation, sedimentation tank, activated sludge method, biofilm me...
