Problems solved by technology

[0002] The traditional method uses a single material to be piled up in the box. During the sewage treatment process, the water flow bed forms a mucous membrane and is easy to coat and form a solid. The solid not only affects the flow rate of the sewage treatment, but also is easy to block, which slows down the speed of sewage treatment. , which in turn results in the inability to make full use of the additives added to the filtration of the sewage, so the machine can only be used for local aeration, but the local aeration of the machine requires the machine to supply air for a long time. After the machine is turned on for a long time, not only the utilization rate is low, but also the operating cost is high

Embodiment 1

[0033] Embodiment one: a kind of aeration ball, such as figure 1 and figure 2 As shown, it includes an outer shell 3 with a spherical outer contour, an inner cavity 2 is opened in the outer shell 3, and a plurality of through holes 1 that can realize self-aeration of the water body are arranged on the spherical surface of the outer shell 3, and the through holes 1 are connected to Inner cavity 2; the inside of the inner cavity 2 is provided with a filter filler block 6 for water filtration.

[0034]The inner cavity 2 can not only make the inner structure of the outer shell 3 hollow, but also make the outer shell 3 be divided into inner and outer layers; secondly, since the number of through holes 1 is several and runs through the outer shell 3, the through holes 1 A fishnet-like penetrating structure can be formed on the outer shell 3; and the filter layer for sewage filtration is installed in the inner cavity 2, so that the outer shell 3 has strong bioadhesion, large specif...

Embodiment 2

[0041] a fluid bed, such as Figure 1 to Figure 3 As shown, it includes an aeration ball and a bed body 7 for sewage treatment, and the bed body 7 is a fluidized bed commonly used in the field of sewage treatment. The outer casing 3 is arranged in the bed body 7 through the packed filter layer 4. The number of outer shells 3 is at least one and is evenly distributed along the axial direction of the bed body 7, and the filter layer is a filler capable of filtering water. By covering all corners of the bed body 7 evenly and fully with the outer casing 3, the bed body 7 can maintain good biological activity and void variability, and can obtain larger and larger specific surface areas during the operation process, while being able to Have a good metabolism. Secondly, by combining an aeration ball with the flow bed, the biomass per unit volume in the bed body 7 can also be increased, thereby achieving the purpose of short hydraulic flow residence time. Secondly, it is also conve...

Abstract

The invention discloses an aeration ball and a fluidized bed applying the same. The invention relates to the technical field of sewage treatment, and solves the problem that a common machine needs long-time air supply for local aeration and then the utilization rate is low and operation cost is high after the machine is operated for a long time. The key points of the technical scheme are as follows: the aeration ball comprises an outer shell with a spherical outer contour; an inner cavity is formed in the outer shell; a plurality of through holes capable of realizing self-aeration of a water body are formed in the spherical surface of the outer shell; the through holes communicate with the inner cavity; and a filtering filling block for filtering the water body is arranged in the inner cavity. Without need of a machine and only through the effects of flowing water in sewage treatment, the purposes that a self-aeration function can be realized, sewage treatment cost of an enterprise iseffectively reduced, high-activity logarithmic growth of microorganisms can be promoted, and water treatment efficiency can be further effectively improved can be achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an aeration ball. Background technique [0002] The traditional method uses a single material to be piled up in the box. During the sewage treatment process, the water flow bed forms a mucous membrane and is easy to coat and form a solid. The solid not only affects the flow rate of the sewage treatment, but also is easy to block, which slows down the speed of sewage treatment. , which in turn causes the sewage to filter and add additives can not be fully utilized, so it can only be used for partial aeration of the machine, but the partial aeration of the machine requires the machine to supply air for a long time. After the machine is turned on for a long time, not only the utilization rate is low, but also the operating cost is high. Contents of the invention [0003] The purpose of the present invention is to provide an aeration ball, which can realize the function of...
