| 摘 要： | 针对再生水回用于景观水体生长的主要藻类普通小球藻，进行了药剂抑制实验。通过实验研究发现，在小球藻生长的对数期分别投入不同剂量的2-甲基乙酰乙酸乙酯（EMA）、大麦秸萃取液（BSE）和异噻唑啉酮3种抑藻药剂后，小球藻的生长受到不同程度的抑制。其中，EMA对藻类的抑制效果甚微，最大抑藻率仅为31%，且对小球藻的生长有低促高抑的作用。BSE对小球藻有明显的抑制作用，且药效期长、不复发；当投加浓度为1 mg/L，能起到抑制藻类生长的作用；当投加浓度为10 mg/L，能起到杀灭水体藻类的作用。异噻唑啉酮可有效抑制小球藻生长，5 mg/L的投加浓度就能起到杀灭水体藻类的作用，且药效期长、不复发。

| Abstract: | The chemical inhibit test on chlorella was studied. Chlorella was the dominant alga in the landscape supplied with reclaimed water. The experimental results showed that the growth of chlorella was inhibited by dosing different concentrations of EMA, BSE and isothiazolinone. EMA could barely inhibit chlorella's growth and presented to be low-promoting and high-repressing. The inhibition rate of EMA was only 31%. BSE could significantly inhibit the growth of chlorella in a long period without relapse. When the dosing concentration was 1 mg/L, BSE could restrain the algal growth; when the dosage reached 10 mg/L, BSE could kill chlorella. Isothiazolinone had a great effect on algal control, and it could kill chlorella at 5 mg/L without relapse. |
