Embodiment 1

[0018] like figure 1 As shown, an aeration tank includes an annular tank 1. A partition plate located in the center of the annular tank 1 is arranged in the horizontal direction in the annular tank 1. A first step aeration part 3 is arranged on the top of the partition plate. The first step aeration The air part 3 includes at least 3 first aeration tanks arranged horizontally, and the at least 3 first aeration tanks are arranged in steps from right to left, and a second step aeration part 2 is arranged at the lower part of the partition. The two-step aeration part 2 includes at least 3 second aeration tanks arranged horizontally, and the at least 3 second aeration tanks are arranged downward in steps from left to right.

[0019] Above the inner partition of the annular tank 1, on the right side of the first step aeration part 3, a rotating brush aeration device 4 is arranged.

[0020] The first aeration tanks are provided with first aerators, and the number of aerators in eac...

Abstract

The invention discloses an aeration tank which comprises an annular groove, wherein a separation plate positioned in the center of the annular groove is arranged in the annular groove in the horizontal direction; a first step aeration part is arranged at the upper part of the separation plate, and comprises at least three first aeration grooves in horizontal arrangement; the at least three first aeration grooves are in step downward distribution from the right side to the left side; a second step aeration part is arranged at the lower part of the separation plate, and comprises at least threesecond aeration grooves in horizontal arrangement; and the at least three second aeration grooves are in step downward distribution from the left side to the right side. Through the arrangement of thefirst step aeration part and the second step aeration part in the annular groove, the aeration efficiency of the aeration tank can be effectively improved; and meanwhile, the aeration can be flexiblyand reasonably performed.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an aeration tank. Background technique [0002] The aeration tank is to stir the sewage through the aeration equipment to speed up the transfer of oxygen in the air to the sewage, thereby increasing the oxygen content in the sewage, and oxidizing and decomposing the organic matter in the sewage. Aeration is one of the main methods of water treatment work and an effective measure to improve the quality and efficiency of water treatment work. [0003] The working principle of the aeration tank is to inject oxygen into the water to be treated to ensure sufficient oxygen supply for the microorganisms in the tank. When the existing aeration tank is in operation, there are aeration blind areas and dead angles, and it is necessary to stir and mix with plug-flow stirring equipment to make the aeration diffuse completely. The aeration efficiency of the existing aeration tank is...
