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。

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.
