Problems solved by technology

[0006] In a natural water body with a wider diameter, although it can be combined in series in the width direction of the river channel, the gradient aeration and directional flow of the water flow can be realized by increasing the number of aeration areas on the suspended base to form an oxidation ditch treatment mode. However, due to the complexity of the natural environment, the above-mentioned suspended rotary disc aerator is used on a wider lake, and the promotion of the water body and the effect of nitrogen and phosphorus removal are affected.

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.

Abstract

The invention discloses an arrangement type rotating disc aeration system suitable for river and lake treatment, the arrangement type rotating disc aeration system comprises a plurality of suspension type rotating disc aerators, the suspension type rotating disc aerators are rotating disc aerators mounted on a suspension type base, each rotating disc aerator comprises a rotating shaft, a driving device and rotating disc plates, and the rotating disc plates sleeve the rotating shaft at intervals; a plurality of suspension type rotating disc aerators are arranged around a circular path at intervals to form a combined body, an opening is formed in the suspension type base, the opening is arranged to be an aeration area, and the rotating disc is immersed into the river channel from the aeration area. The openings in the suspension type bases are closed openings in the suspension type bases or open openings distributed in the same direction in the radial direction facing the circle center or in the tangential direction of the circumference. A plurality of suspension type rotating disc aerators are arranged at intervals around a circular path to form a combined body, and continuous high-power aeration is carried out on a non-flowing lake, so that vortex-shaped or radial mixing of sewage in a treatment area is realized.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an arrangement-type rotary plate aeration system suitable for river and lake treatment. Background technique [0002] With the development of social production, the water quality of rivers all over the world is facing different degrees of pollution from industry, agriculture, life and other aspects. Therefore, since the 1950s and 1960s, developed countries such as Britain, Germany, and the United States have begun to consider solving the increasingly serious problem of river pollution. In recent years, the water environment quality problems of urban rivers have gradually become prominent. Some rivers fail to meet the requirements of relevant water environment targets, and even many rivers have black and odorous phenomena, which urgently need to be resolved. [0003] Therefore, different technical routes have emerged in response to the problems existing in the current river course...
