Embodiment 1

[0032] combined with Figure 1-2 , this embodiment provides a rotating drum mechanism, including: a rotating drum body, the rotating drum body includes an inner rotating drum 1 and an outer rotating drum 2, the outer rotating drum 2 is sleeved on the inner rotating drum 1, and the There is a gap 9 between the outer drum 2 and the inner drum 1, and the gap 9 is filled with denitrification, phosphorus removal and nitrogen removal carriers; Covered on the outer surface of the outer drum 2 .

[0033] In this application, by setting the drum body to include an inner drum 1 and an outer drum 2, there is a gap 9 between the inner drum 1 and the outer drum 2 to form a cavity, and the cavity formed by the gap 9 is filled with denitrification The dephosphorization and nitrogen removal carrier enables the drum to simultaneously remove nitrogen and phosphorus in sewage while removing large suspended solids in sewage during sewage treatment. At the same time, by setting multiple pieces o...

Embodiment 2

[0036] In a rotating drum mechanism of this embodiment, compared with the technical solution of Embodiment 1, the filter cloth and the outer rotating drum 2 are detachably connected. The arrangement is convenient for disassembly and assembly, and at the same time, it is convenient to disassemble the filter cloth for cleaning.

Embodiment 3

[0038] In the drum mechanism of this embodiment, compared with the technical solution of Embodiment 1, the inner drum 1 is formed by splicing a plurality of grid screens (not shown in the figure), which is convenient for disassembly and assembly.

Abstract

The invention discloses a rotary drum mechanism and a sewage treatment device, and relates to the technical field of sewage treatment equipment.The rotary drum mechanism comprises a rotary drum body, the rotary drum body comprises an inner rotary drum and an outer rotary drum, the outer rotary drum is connected to the inner rotary drum in a sleeving mode, and a gap is formed between the outer rotary drum and the inner rotary drum; the gap is filled with a denitrifying phosphorus and nitrogen removal carrier; the plurality of pieces of filter cloth are sequentially spliced and coated on the outer surface of the outer rotary drum. Compared with a rotary disc in a traditional cloth filter tank, the rotary drum is of a double-layer structure, in the sewage treatment process, the rotary drum has the functions of removing large-particle suspended solids in sewage and synchronously removing nitrogen and phosphorus in the sewage, the multifunctionality of the rotary drum is achieved, blocking of the filter cloth can be effectively reduced, and the filtering effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a drum mechanism and a sewage treatment device. Background technique [0002] At present, in sewage treatment, especially in advanced sewage treatment, the commonly used equipment for removing total suspended solids is the rotary disc filter cloth filter, which has the advantages of good treatment effect, stable water quality and quantity, and simple and convenient operation and maintenance. However, the existing rotary disc filter cloth filter has a single function, only has the function of removing fixed suspended solids in the terminal sewage, and cannot treat nitrogen and phosphorus in the sewage, and the filtration speed of the rotary disc is low and the cleaning is complicated. At the same time, in the existing rotary disc filter cloth filter tank, the filter cloth covered on the outer surface of the drum is basically one piece (that is, a single piece), ...
