Enhancing Biological Treatment

Ultrasonic technology can improve the solid-liquid interface, enhance gas phase mass transfer and nutrient transfer, and strengthen biological treatment. o. Schlafer researchers used low power ultrasound to treat brewery industrial wastewater, and the bioreactor treated well. In the experiment, the ultrasonic power was 0.3 w/l and the frequency was 25 kHz. after ultrasonic treatment, the floc concentration was increased from 0.12 g/l to 0.4 g/l, and the treatment efficiency was increased by 50%.

Treatment Of Black Liquor Of Papermaking

Black liquor is a waste liquid composed of lignin and humic acid. Treating it is a difficult problem. Our company adopts pfs/h2o2 and ultrasonic treatment. Comparison found that the removal rate of CODCr increased by about 13%, the removal rate of PFS decreased by 14%, and the removal rate of H2O2 decreased by 50-80%. Ultrasonic technology and oxidation technology were used to treat the black liquor of paper making.

Decomposition Of Organic Matter Using Ultrasonic Physical Energy Field

Physical energy fields are widely used in water treatment. Combining ultrasound with other physical energy fields (light field, electric field, magnetic field) is one of the research directions. The combination of ultrasound and ultraviolet light is used to treat domestic sewage and decompose organic matter. Studies have shown that there are three roles in the decomposition process: ultraviolet decomposition, ultrasonic oxidative decomposition of hydroxyl groups, and ultraviolet decomposition of air to decompose ozone.
