  • Abstract
The inactivation efficiencies of Synedra sp. by NaClO and KMnO4 oxidation were investigated. The results indicated that in the range of 0~5 mg/L in the neutral condition, the inactivation efficiencies increased with the increase of NaClO dosage and the optimun dosage was 3 mg/L. Meanwhile NaClO showed a better degradation ability in acidic condition. The degradation ability of KMnO4 was not significant, indicating that KMnO4 had no effect on inactivation. Chlorination was effective for Synedra sp. inactivation, and however led to cell disintegration and organic matter release, thus endangering the safety of drinking water.
