固体二氧化氯杀藻实验研究

摘要

以富营养化水体为研究对象,以固体二氧化氯为杀藻剂,进行了杀藻效果研究,考察了投药量、接触时间、pH值对固体二氧化氯杀藻效果的影响,筛选出了最佳实验条件:pH值为5、接触时间为1.5h、投药量为15～25 mg/L时可获得较高的杀藻率,并讨论了将其作为教学实验的可行性.%Experiments were performed to investigate the removing efficiency of algae in eutrophic water by using solid ClO2.The influence of chemical feed dosage, reaction time and pH on the effect of algae killing is explored,and the best processing conditional limit is achieved.When pH is 5,the reaction time is 1.5 hours, and the chemical feed dosage is 15mg ·L-1~25mg·L-1 ,the higher efficiency of algaecide is achieved and the feasibility of teaching experiment is discussed.
