Before the water enters the high-efficiency air flotation, clarification, and self-flushing filtration machine 7, PAC coagulant and PAM coagulant are added, and the wastewater after reaction and coagulation in the tubular mixer enters the high-efficiency air flotation, clarification, and self-flushing filtration The all-in-one machine 7, the clear water after the integrated process of air flotation, reaction, flocculation, oil separation, slag collection, sedimentation, clarification, filtration, and self-flushing enters the clear water pool 9, and most of the water in the clear water pool 9 reaches the standard through the discharge port 10 Outward discharge, the discharged sludge water processed by the high-efficiency air flotation, clarification, self-flushing and filtering integrated machine 7 enters the sludge thickening tank 35 through the output mud pipeline 24 and then is treated separately.

In the actual use process: the water pressure of the raw water entering the water inlet of the equipment should be >0.07MPa. Two static pipeline mixers are installed in front of the high-efficiency air flotation, clarification, and self-flushing filtration machine 7, one is used for adding PAC coagulant for water treatment, and the other is used for adding PAM coagulation aid when the turbidity is high agent. The water treatment agent (PAC coagulant) is prepared in the first dosing device 4, and is metered and pumped to the static pipeline mixer (namely the first pipeline mixer 2), and the static pipeline mixer passes through the shear of its own structure. Cut and stir to make it evenly mixed, and then enter the water purification device.

After the raw water enters the high-efficiency air flotation, clarification, self-flushing and filtering integrated machine 7, it first enters the water distribution area in the middle of the device, and performs rotary tangential spraying in the first-stage separation cylinder 36 through the rotating shaft 21 to distribute water evenly. The mixing method with the function of hydraulic stirring and reaction can fully react the suspended solids and chemicals in the water, and there is a sludge return hole, so that the formed alum flowers can fully contact with the impurities to form large alum flowers, and then the rotary cut cloth The small rotary cutting water distribution device on the upper part of the water device pushes and rotates, making the formed large alum flowers denser and larger, and achieving rapid sedimentation and separation. While the water distribution reaction is stirred and separated, the compressed air is connected to release a large amount of compressed air, which makes it mix with the air flotation releaser 27 in the outer and lower part of the primary separation cylinder 36, forming the air flotation principle of air-water mixed water, rising The water and oil are discharged and separated through the top opening of the central reaction cylinder 25 and the space in the inverted cone funnel 18, the oil and scum floating on the water enter the inverted cone funnel 18, and the water enters the steady flow tube 16, which can not only improve The reaction is carried out well, and the oil and scum contained in the water can be removed, and the organic matter in the water can be removed at the same time, and precipitated and separated, and the water is discharged from the top of the central reaction cylinder 25, which is the high-efficiency air flotation function.

The water clarified through the inclined pipe enters the filtration and backwashing chamber 14 through the water collection and gravity water distribution system on the upper part of the water purification device, and is filtered from top to bottom through the filter layer, and the alum flowers in the water are intercepted by the filter layer ,filter. The filtered clean water is collected to the clean water area at the bottom of the device through the filter head, and returned to the clean water layer at the top of the device through the connecting pipe. The raw water flows into the clean water pool 9 after being purified in the water purification device, and then is sent to the water point by the secondary pump station; the discharged sludge water treated by the high-efficiency air flotation, clarification, self-flushing and filtering integrated machine 7 enters through the output mud pipeline 24 The sludge thickening tank 35 is treated additionally.
