| 摘 要： | 在运行稳定的连续流活性污泥系统中采用超声处理剩余污泥并将其返回系统中．研究在不影响出水水质的前提下实现污泥减量化的条件。试验表明：在声能密度0．8W／mL、超声作用时间60s，系统运行稳定后，出水CODCr质量浓度为46mg／L，单位MLSS的SVI为82．6mL／g。此时，系统出水达到CB18918--2002《城镇污水处理厂污染物排放标准》一级排放标准，污泥沉降性良好，污泥减量效果明显。 |

| Abstract: | The conditions of excess sludge reduction were studied guaranteeing the water quality unchanged when excess sludge was treated by ultrasonic and returned to sludge system in stable running continuous flow activated sludge system.The results showed that the effluent COD was 46 mg/L and the SVI was 82.6 mL/g MLSS,when the system operated steadily with the sound energy density at 0.8 W/mL and ultrasonic time at 60 s.The effluent COD could achieve one-level emission standard based on contamination emission stan... |
