| Abstract: | Based on the turbidity,lower temperater and micropolluted of cellar water in towns ,using powdered activated carbon combined with for enhanced coagulation. The effect of powdered activated carbon to remove organic matter comparing them with coagulant PAC adding at separate are investigatel, the effect of their enhanced coagulation are studied. The result shows ： under the condtion PAC dosage 70 mg/L, the mixed - stirring rate 300 r/min, the stirring time 0.5 min, the flocculation - stirring rate 60 r/min, the stirring time 20 min, the settling time 15 min, by activated carbon dosage in 3 min after adding coagulant, the removal rate of turbidity and CODMn are increased 12% and 15.3% compared with conventional coagulation, the experiment also proved that there have synergies between them. |
