摘　　要：针对传统氯消毒在实际应用和运行中产生有害消毒副产物的缺点,着重将新兴消毒技术———超声波消毒技术与传统次氯酸钠消毒结合起来。二级出水的大肠杆菌数为107个/L左右,试验确定超声波与氯协同的最佳参数如下:超声波功率为0.30A×220V,超声波作用时间为30s,有效氯为2.30mg/L,氯作用时间为30min。实验采用的是同时处理方案,处理单位体积(1m3)水样的耗电量为0.55(kW.h)/m3。The traditional chlorine disinfection would produce harmful disinfection by-products （DBPs） in the practical application and operation. In views of this disadvantage, the newly developed ultrasonic disinfection technology was combined with traditional sodium hypochlorite disinfection secondary effluent. The optimum operation parameters of combination process were identified as follow：ultrasonic power was 0.30 A × 220 V, ultrasonic time was 30 s, active chlorine concentration was 2.30 mg/L,chlorine reaction time was 30min, the ultrasonic disinfection and traditional sodium hypochlorite disinfection were operated simultaneously. Under these optimum operating conditions, the energy consumption of combination process was 0.55 （kW · h）/m3.
