We used several organic algaecides to remove the phaeocystis globosa red tide . the results showed that povidone - iodine can release iodine slowly to kill and control the p . globosa red tide . the minimum used levels are 30mg / l if we added the povidone - iodine algaecide at the prophase of logarithmic phase 本文研究了缓释除藻剂碘伏对棕囊藻的去除作用，发现碘伏有一定的除藻能力，在棕囊藻指数生长期前期加入碘伏，最低有效除藻浓度为30mg / l 。

The effects of povidone - iodine and isothiozolone on the phaeocystis globosa ' s chlorophyl , protein and sod enzyme were studied , and the modality of the algae cell was observed by sem to understand the extinguishing mechanism of algaecide 摘要通过研究碘伏和异噻唑啉酮对球形棕囊藻叶绿素、蛋白质和超氧物歧化酶( sod )的影响，并使用扫描电子显微镜观察棕囊藻的形态结构的破坏情况，初步探讨了这两种除藻剂单独作用和复配使用时灭杀球形棕囊藻的机理。

The experimental results showed that in the condition of this experiment four algaecides all had strong removing rate on algae , and their removing rate increased with dose increasing , and decreased with algae density increasing . according to the removing rate on algae and cost value or so , the sequence of four algaecides from good to bad were potassium permanganate , copper sulfate , hydrogen peroxide and sodium hypochlorite . in the condition of this experiment , the suitable dose of potassium permanganate was 0 . 8mg / l , the algal removing rate was beyond 90 % and the cost of this algaecide was only 0 . 0068 / m3 . the efficiency of algae removal by four algaecides for huanghe river water was studied . the results showed that the majority of huanghe river water was bacillaroiphyta , and the dominant genera was melosira , which reached 78 % ~ 94 % 结果表明，在实验条件下，四种杀藻剂均具有一定的杀藻效果，藻类去除率均随药剂投量的增加而提高；原水藻类数量影响杀藻剂杀藻效果，四种杀藻剂的藻类去除率均随原水藻类数量的增加而降低；通过杀藻效果、经济性以及安全性等方面的综合比较，对于以有毒蓝藻为优势藻属的引滦水，四种杀藻剂的优劣程度从优到劣排序为：高锰酸钾硫酸铜过氧化氢次氯酸钠；在实验条件下，高锰酸钾适宜投加量为0 . 8mg l ，藻类去除率高于90 ，所需的药剂费用仅为0 . 0068元m ~ 3 。
