Dissolved air flotation machine in the operation process may appear some minor faults, I summarize the faults and solutions:
1, contact area slag surface is not flat, local bubbles or unstable water flow, should be removed to exclude blockage of the releaser; separation of the area of the flotation surface is not flat, the surface of the pool is common large bubbles rupture, it shows that the bubble A bad adhesion with flocculation particles, should check the well on the coagulation system to adjust; unqualified water back to the collection well, qualified water into the subsequent treatment system.
2, control the air flotation pool water regulator or movable weir plate, the air flotation pool water level stabilized in the slagging tank below the mouth of 5 ~ 10cm. to be stabilized after the water level, with a flow meter, water meter and other equipment to measure the amount of treated water, and in and out of the water asked the door to adjust, until it reaches the design flow rate.
3, in the early stage of operation to constantly test the main water quality indicators. Unqualified water should be passed beyond the direct water system, or still back to the collection well. Qualified, before entering the subsequent treatment structures or reuse.
4, through the pool surface and the observation window to check the air flotation pool with gas floc floating and slag accumulation. To be scum accumulates to 5-8cm, start scraping machine for scraping. Check whether it is possible to scrape slag, slag tank overflow is uniform, whether the flow of slag is difficult to scrape the slag machine traveling speed is appropriate, whether the water quality is affected.
Dissolved air flotation machine scope of application
