Abstract :
In order to enhance the coagulation pretreatment of a reclaimed water plant, an experiment was employed by means of the Polymerization Aluminum Chloride (PAC), the Polyferric Sulfate (PFS) and the Ferric Trichloride (FeCl3). The performances of Powder Active Carbon (PAC) and Pre-coagulation Chlorine Addition using as coagulant aids were also discussed. The results showed, turbidity removal could reach 87.5% by using PACl as coagulant, optimum dosage should be 12~ 16mg/L; Compound of PSF and PACl had better performance than Compound of FeCl3 and PACl; PAC and Pre-coagulation Chlorine Addition could enhance the effect of coagulation process.
