The Brief Introduction Of The Functions And Handling Precautions Of The Air Flotation Tank Equipment

The function of the air flotation tank equipment is to pre-treat the suspended solids, colloid and most organic matters in the sewage. The reaction zone alumen ustum formation effect is also very good (large and dense). The overall unity effect of the scum in the floating area is better, and scum needs to be scraped off in a timely manner. The air floating effluent is relatively clear, and the treatment load of the subsequent biochemical pool is reduced.

When using the air flotation tank equipment, attention should be paid to the reaction, dissolved gas and slag scraping three units operating points and sequence of the air flotation tank. If it is not started for the first time, it is necessary to add medicine first, open the adjusting tank to lift the pump inlet and adjust the dosage and effect. Open the air flotation system and after the slag formation, and then open the slag scraper.

When starting the dissolved air pump, be sure to close the intake valve. For dissolved air pump, it is strictly prohibited to appear idling without water. During normal operation, the pressure range of the vacuum gauge at the inlet of the dissolved air pump should be controlled within 0.01 - 0.02MPa (negative pressure). The outlet pressure of the dissolved air pump should be controlled at 0.4 - 0.5mpa..

Some problems should also be noted when the equipment of the air flotation tank equipment is shut down for a long time ( more than 3 days ) due to maintenance and other conditions.

Because of the above problems, it is necessary to timely discharge the possible bottom mud in the air flotation tank into the sludge tank to prevent the sludge from being deposited for a long time and blocking the flow channel. During normal operation of the air flotation tank equipment, the bottom mud is discharged every half a month, and the operator must keep in mind.http://www.shallowairfloatation.com/
