摘　　要：本文根据上海东区污水厂剩余活性污泥的气浮浓缩试验结果,获得了气浮法浓缩城市污水厂活性污泥的主要设计参数:溶气压力P、气固比α_s和固体负荷L_B,并论证了选取参数的依据。A study on thickening waste activated sludge was carried out in pilot-scale dissolved-air flotation unit in Shanghai East Wastewater Treatment Plant. Major parameters (air dissolving pressure, air/solid ratio and solid loading rate) for the process design were obtained. Basis of their choice are also explained in this paper.
