Embodiment 1
[0039] Embodiment 1: As shown in Figure 7, an arrangement-type rotating disc aeration system suitable for river and lake governance includes several suspended rotating disc aerators 1, and the suspended rotating disc aerator 1 is installed on The rotating disc aerator 2 on the suspension base, the rotating disc aerator includes a rotating shaft 2.1, a driving device 2.2 and a rotating disc disc 2.3 installed on the rotating shaft at intervals, and the driving device 2.2 is a reducer 2.2 that can be rotated forward and reverse .1 and the motor 2.2.2, the motor 2.2.2 is connected to the power supply 4 through the waterproof cable 3 to realize power-on operation, the suspension base 1.1 is provided with an opening 1.3, the opening 1.3 is set as the aeration area 5, and the rotating disc 2.3 Immerse into the river channel from the aeration area 5, the immersion depth is 0.8-2.5 m, the sensor system 9 is set on the disc 2.3 of the rotating disc, when the interception amount of organ...
Embodiment 2
[0040] Embodiment 2: as Figure 10 As shown, referring to Embodiment 1, other features remain unchanged, and the openings 1.3 on each suspension base 1.1 are arranged in the same radial direction toward the center of the circle. The direction of the opening, that is, the pushing direction 10 of the water flow in the aeration zone 5, is along the radial direction of the circle formed by the arrangement of the suspended rotary disc aerator 1, and the rotating disc 2.3 rotates to drive the deep water with the circular agitation of the shallow layer. The circular flow realizes the local vortex of the water body, thereby forming the phenomenon of negative pressure drainage, accelerating the water flow replacement in the local aeration area, which is beneficial to the transfer and diffusion of oxygen and the mixing of liquids, and can also accelerate the oxygen enrichment process of the water body, thereby improving the good Aerobic microbial dynamics form aerobic zone 6-facultative...
Embodiment 3
[0041] Embodiment 3: as Figure 13 As shown, with reference to Example 1, the rest of the features remain unchanged. Several suspended rotary disc aerators 1 are arranged at intervals around circular and linear paths to form a combination, forming an annular floating rotary disc aeration system and a linear floating rotary aerator. Compared with Embodiments 1 and 2, the arrangement pattern combined with the disc aeration system has a better water displacement effect. The rotation of the disc 2.3 greatly enhances the water flow, which is beneficial to the transfer and diffusion of oxygen and the mixing of liquids. , since the openings 1.3 on each suspension base 1.1 are as Figure 5 As shown, the two adjacent aeration zones 5 will form a local aerobic zone 6 - aerobic zone 7 - anaerobic zone 8 - aerobic zone 7 - aerobic zone 6, which can better decompose organic pollution in wastewater things.
