Abstract：
 The present invention belongs to the field of water treating technology, and aims at providing one kind of cheap and pollution-free algae inhibitor. The preparation process of algae inhibitor includes the following steps: crushing reed as material and lixiviating with organic solvent to obtain extractive liquid; eliminating suspended grain from the extractive liquid and concentration to obtain white precipitate an and paste B; extracting the paste B with CHCl3/hydrochloric acid to obtain water phase extractive liquid C; and concentrating extractive liquid C and extracting with ethanol/petroleum ether to obtain ethanol phase with dissolved algae inhibitor in the lower layer. The said process is simple, cheap and non-toxic.
