摘　　要：采用高锰酸钾、二氧化氯、硫酸铜、生石灰4种化学药剂对水节霉(Leptomitus lacteus)共生体控制效果进行研究,以投加化学药剂前后水节霉共生体生长的生物量变化来反映控制效果,并对投加化学药剂前后水节霉共生体水溶液的水质变化及4种化学药剂的经济性进行了分析。结果表明,投加高锰酸钾、二氧化氯、硫酸铜、生石灰4种化学药剂均对水节霉共生体有一定的控制效果,当投加量分别为1.5,1.5,2.0和40mg/L时,水节霉共生体生物量降低率均达到最大值,分别为68.0%,63.1%,67.0%和76.8%。综合水节霉共生体的控制效果、经济性以及投加化学药剂前后水节霉共生体水溶液的水质变化得出,应急投加时4种化学药剂从优到劣排序为二氧化氯>高锰酸钾>硫酸铜>生石灰;收集后岸上处置时4种化学药剂从优到劣排序为生石灰>高锰酸钾>硫酸铜>二氧化氯。The chemical agents of potassium permanganate,chlorine dioxide,copper sulfate and caustic lime were used to study their effects on the growth activity of Leptomitus lacteus symbiont.The variation of microbial biomass of Leptomitus lacteus symbiont before and after dosing the chemical agents was used to reflect the control effect.The water quality variation in water solution of Leptomitus lacteus symbiont before and after dosing the chemicals and the cost of them were analyzed.The results show that the four chemical agents all have some control effects on Leptomitus lacteus symbiont,and when their dosage were 1.5,1.5,2.0 and 40 mg/L,the maximum decrease rate of Leptomitus lacteus symbiont were obtained,being 68.0%,63.1%,67.0% and 76.8%,respectively.According to comprehensive comparison of the control effect on Leptomitus lacteus symbiont,the cost and the water quality variation before and after dosing the chemical agents,the sequence of the four chemicals for emergency from good to bad is chlorine dioxide〉potassium permanganate〉copper sulfate〉caustic lime;while the sequence of treating after collection is caustic limepotasslum permanganatecopper sulfatechlorine dioxide.
