摘　　要：以针杆藻（Synedra sp 。）为研究对象，考察了 NaClO 与 KMnO4在不同投量和不同 pH 条件下对针杆藻的灭活特点以及对光合活性的影响。结果表明，在0～5 mg／L 投加范围内，NaClO对针杆藻的灭活效果随剂量的增大而提高，投加量为3 mg／L 是抑制藻活性的最佳投量，并且在酸性条件下 NaClO 能更好的发挥其氧化降解的作用；KMnO4对针杆藻的降解效果不明显，说明投加KMnO4（≤5 mg／L）对针杆藻没有很好的灭活效果。氯化对针杆藻灭活效果好，但是会造成细胞解体，引起藻内有机物的释放，危及饮用水安全。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＆nbsp;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.
