摘要

The effects on algae removal imposed by ultrasound technology employing different combinations of parameters, including frequency, power and irradiation time, were estimated using response surface methodology. This technology was applied in the backwater area of Penxi river in the three Gorges Reservoirs. Results showed that, the algae removal rate by ultrasound was 64.1 %, at an optimal frequency of 45 KHz, input power of 60 W and irradiation time of 48 s. After 2 h of ultrasound irradiation on the 500 m~2 study field, the algae density dropped from (1.10 +0.02) × 10~7 to (2.1 ±0.1) × 10~6 cells/mL. Chlorophyll-a concentration dropped to 13.8 % of its initial amount algae were effectively controlled. Ultrasound technology is concluded to be effective for algae removal and can thus be applied to algal blooms.
