采用超声波处理石化污水处理厂的剩余活性污泥。
Ultrasound process can be used in treatment of residual activated sludge from petrochemical wastewater treatment plant.
用气浮法对某工业污水处理厂的剩余活性污泥进行了浓缩研究。
Wasted activated sludge from industrial wastewater treatment plant was thickened by air flotation.
改进型涡凹气浮用于浓缩低浓度剩余活性污泥时浓缩效果好，固体负荷高，出水SS低，比涡凹气浮更适合于低浓度剩余活性污泥浓缩。
MCAF exhibits excellent thickening efficiency with high solid loading and low SS effluent, therefore is more suitable for thickening low concentration excess sludge.
