The raw water pool 1 is communicated with a water outlet pipe of the metering pump 9, and a water inlet pipe of the metering pump 9 is communicated with the medicine dissolving tank 8. The first medicine dissolving tank 8 is provided with a first stirring machine 10, and stirring blades of the first stirring machine 10 are arranged in the first medicine dissolving tank 8. The aeration mechanism 3 is composed of an air compressor 31, a dissolved air tank 32 and a dissolved air releaser 33, wherein an air outlet pipe of the air compressor 31 is communicated with the dissolved air tank 32, an water inlet of the dissolved air tank 32 is communicated with a water outlet pipe of the reflux pump 6, a water inlet pipe of the reflux pump 6 is communicated with the clean water tank 5, a water outlet of the dissolved air tank 32 is communicated with the dissolved air releaser 33, and the dissolved air releaser 33 is communicated with the dissolved air water pipe 43. And a second stirrer 11 is arranged on the raw water pool 1, and stirring blades of the second stirrer 11 are arranged in the raw water pool 1. Threaded rods are fixed at two ends of the notch of the groove body 41 and penetrate through waist-shaped holes in the baffle 49, and nuts are connected to the threaded rods in a threaded mode. The water inlet pipe 42 and the groove body 41 are both provided with a liquid discharge port 40.
As shown in fig. 1, the sewage to be treated is discharged into a raw water tank 1, and a raw water pump 2 pumps the sewage in the raw water tank 1 and feeds the sewage into an air flotation tank 4 through a sewage pipe 44. The aeration means 3 sends the dissolved air water into the air flotation tank 4 through the dissolved air water pipe 43 while the sewage pipe 44 sends water. The sewage and the dissolved air water are mixed in the air flotation tank 4, thereby aerating the sewage. In the aeration process, scum of oily substances, macromolecular organic matters and the like can be separated from water. The scum floats on the water surface. Finally, the air flotation tank 4 guides the scum positioned at the uppermost layer into a scum tank 7, and guides the clear water positioned below the scum into a clear water tank 5. And finally, the clean water in the clean water tank 5 is guided into other stations for treatment.
The aeration mechanism 3 is operated by feeding compressed air into the dissolved air tank 32 through the air compressor 31, feeding clean water into the dissolved air tank 32, dissolving the air in the clean water sufficiently by the dissolved air tank 32 to form dissolved air water, and finally releasing the dissolved air water into the dissolved air water pipe 43 through the dissolved air releaser 33 and feeding the dissolved air water into the air flotation tank 4 through the dissolved air water pipe 43. The clean water in the dissolved air tank 32 can be supplemented and supplied by the treated clean water in the clean water basin 5, and the clean water basin 5 is communicated with the dissolved air tank 32.
The second stirrer 11 stirs the sewage in the raw water tank 1, so that the sewage can be prevented from settling, and the sewage is more uniform.
In some kinds of sewage treatment, it is necessary to add a chemical for accelerating the separation of water and scum, and at this time, the chemical is put into the chemical dissolving tank 8 and the chemical is pumped into the sewage in the raw water tank 1 by the metering pump 9. The first stirrer 10 can stir the liquid medicine in the medicine dissolving tank 8 uniformly.
Referring to fig. 2, 3 and 4, the water and scum in the air flotation tank 4 are separated in such a manner that the air-dissolved water is fed into the water inlet pipe 42 through the air-dissolved water pipe 43 and the sewage is fed into the water inlet pipe 42 through the sewage pipe 44, and the sewage and the air-dissolved water can be more sufficiently mixed because the water outlet of the air-dissolved water pipe 43 and the water outlet of the sewage pipe 44 are vertically opposite to each other. After the water inlet pipe 42 is filled, the mixed water overflows from the trumpet-shaped opening of the water inlet pipe 42 and flows into the tank body 41. The sewage is aerated in the tank body 41 to promote separation of scum from water. Scum in the aerated sewage floats on the uppermost layer, and separated clear water is arranged below the scum.
When the water level of the scum is higher than the notch on the tank body 41, the scum flows out of the tank body 41 through the notch, and the scum flowing out of the tank body 41 directly enters the sewage area of the annular groove 48 and then enters the scum tank 7 through the sewage discharge pipe 45 communicated with the sewage area. So that the uppermost dross can be first drawn into the waste region of the annular trough 48 and removed by controlling the water level in the trough 41.
The clear water part of the tank body 41 enters the water inlet at the bottom end of the balance liquid level pipe from the through hole on the tank body 41, and flows out of the water outlet at the top end of the balance liquid level pipe into the clear water area of the annular groove 48 along with the rising of the clear water liquid level in the tank body 41. Therefore, as long as the liquid level of the scum is higher than the height of the water inlet at the bottom end of the balance liquid level pipe, the scum can not enter the clean water area. Finally, the clean water flows into the clean water tank 5 through a water production pipe 46 communicated with the clean water area.
A baffle 49 is installed at the opening of the tank 41 for flowing the dross, and the opening area of the opening can be adjusted according to the thickness of the dross. Two threaded rods are fixed on the inner wall of the groove body 41, and a notch on the groove body 41 for floating slag to flow through is positioned between the two threaded rods. Waist-shaped holes are respectively formed in two sides of the baffle 49, two threaded rods respectively penetrate through the waist-shaped holes in the two sides of the baffle 49, then the threaded rods move up and down along the waist-shaped holes when the baffle 49 moves up and down, nuts are connected to the threaded rods in a threaded mode after the baffle 49 moves in place, the baffle 49 is fixed on the inner wall of the groove body 41, and the baffle 49 at the moment shields a part of the groove opening, so that the liquid level height of scum entering a sewage area is adjusted.
The number of the clear water areas communicated with the annular groove 48 and the balance liquid level pipes 47 connected with the groove body 41 is more than one.
When the interior of the air flotation tank 4 needs to be cleaned, the cleaning solution is introduced into the air flotation tank 4 for cleaning, and the waste water after cleaning can be discharged through the liquid discharge port 40 on the water inlet pipe 42 and the liquid discharge port on the tank body 41.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
