滦河水的除藻实验研究

该文针对滦河源水进行了杀藻的试验研究。研究结果表明：对引滦水而言，硫酸铜、高锰酸钾和过氧化氢三种杀藻剂的藻类去除率均随药剂投量的增加而升高；在原水含藻量较高（高于1000万个／L）情况下，硫酸铜较佳投量1．0mg／L，藻类去除率为70％～80％；过氧化氢投量4mg／L，藻类去除率为60％左右；高锰酸钾投量0．6mg/L，藻类去除率为85％；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的引滦水，三种杀藻剂的优劣排序为：高锰酸钾〉硫酸铜〉过氧化氢。

Algae Removal in Luan River Water with Chemical Method

The efficiency of algae removal by three algaecides for Luan River water was studied. The experimental results showed three adgaecides gave strong removal rate on algae, and their removal rate increased with dose increasing. When the algae density was high, in order of 10^7 eells/L in the water of Luan River, the suitable dose of copper sulfate, hydrogen peroxide and potassium permanganate are 1.0mg/L 4.0mg/L and 0.6mg/L respectively, and the removal rate of algae were 70%-80%, 60% and 85%. According to the removal rates of algae and costs, and the sequence of choice of these three algaecides are in order of potassium permanganate, copper sulfate and hydrogen peroxide.
