Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1 and 2, the shallow air flotation sewage treatment device includes a treatment tank 10 and an air flotation machine 60, wherein the treatment tank 10 is provided with an air flotation zone 11 and a sludge zone 12, and the air flotation zone 11 and the sludge zone 12 are arranged in the length direction of the treatment tank 10. Specifically, a water inlet tank 40 is arranged at the top end of the treatment tank 10, the bottom end of the water inlet tank 40 is communicated with the air floating area 11, an air floating machine 60 is arranged at the bottom end of the air floating area 11, and the air floating machine 60 is used for generating air bubbles. The top end of the air flotation zone 11 is provided with a sludge plate 20, and the sludge plate 20 is provided with a plurality of hole sites.
In addition, be equipped with on the treatment tank 10 and scrape mud subassembly, scrape mud subassembly and include actuating mechanism 32 and scrape mud piece 31, will scrape mud piece 31 and locate on mud board 20, actuating mechanism 32 is used for driving and scrapes mud piece 31 and move in order to propelling movement mud to mud district 12 along the length direction of treatment tank 10.
On the basis of the structure, use the utility model discloses a during shallow layer air supporting sewage treatment plant, can be with the leading-in water pitcher 40 of sewage, through the leading-in air supporting district 11 of sewage of the bottom of water pitcher 40, start air supporting machine 60 simultaneously, air supporting machine 60 can produce the microbubble in air supporting district 11. The bubbles can be combined with oil drops, suspended impurities and the like in the sewage to drive the impurities in the sewage to float upwards, and the floated bubble impurity combination floats upwards to the sludge plate 20 through the hole sites on the sludge plate 20 and is settled on the sludge plate 20.
So, impurity in alright the removal sewage, because the mud that forms is detained on mud board 20, therefore can start actuating mechanism 32, actuating mechanism 32 drives scrapes mud piece 31 reciprocating motion on mud board 20, and mud alright propelling movement on mud board 20 carries out centralized processing to mud district 12, prevents that mud from detaining, improves sludge treatment efficiency and quality.
It should be noted that the air floating machine 60 in the present embodiment may be selected as the dissolved air floating machine 60 in the prior art, and is purchased from the market directly, and the specific structure and the operation principle thereof do not belong to the technical content to be protected in the present application, and are not described in detail herein.
