摘要：

Removal of poliovirus 1 by activated sludge treatment in batch experiments was investigated. Virus counts were reduced by more than 99% under conditions of 0. 2 to 0. 4 kg BOD multiplied by (times) kg MLSS** minus **1 multiplied by (times) day** minus **1 and MLSS (mixed liquor suspended solids) concentrations of 1000 to 2000 mg multiplied by (times) 1** minus **1. There were no distinct relationships between BOD-SS loadings or total organic carbon of the effluent and virus inactivation rates. MLSS levels of more than 800 mg multiplied by (times) 1** minus **1 were necessary for more than 99% reduction in viral counts. although MLSS levels of more than 2000 mg multiplied by (times) 1** minus **1 reduced viral counts by 4 log values, factors such as low temperatures and anaerobic conditions which adversely affect the efficiency of activated sludge processes, resulted in prolonged virus survival.
