摘　　要：This present paper studied the technological characteristics of seawater treated by sand filtering, net filtering and reserve-water disinfection.The results showed that after treatment the average filtering ratio of phytoplankton was 89.98%,and that of zooplankton was 89.5%; that it can isolate the other species of shrimp and crab by the filtering net of more than 40 mesh,and it was difficult for Copepoda to pass through the filtering net of more than 60 mesh,so it can block the horizontal disseminate pathway of WSSV; and that 6×10-6 of the efficient chlorine can kill Copepoda but most aquatic creatures were dead in the water treated by 10×10-6 of the efficient chlorine, and it can transfer algae after killing the harmful creatures by using bleaching powder when there was reserve water. The result of water culture for 4 days, in out-seawater and the water treated with sand filtering or net filtering of 60 mesh or 6×10-6of efficient chlorine, showed that the species and quantity of plankton were the most by out-sea-water culture, and it reduced respectively in the water treated by filtering with 6 mesh,sand filtering and 6×10-6 of efficient chlorine.This present paper studied the technological characteristics of seawater treated by sand filtering, net filtering and reserve-water disinfection.The results showed that after treatment the average filtering ratio of phytoplankton was 89.98%,and that of zooplankton was 89.5%; that it can isolate the other species of shrimp and crab by the filtering net of more than 40 mesh,and it was difficult for Copepoda to pass through the filtering net of more than 60 mesh,so it can block the horizontal disseminate pathway of WSSV; and that 6×10^(-6) of the efficient chlorine can kill Copepoda but most aquatic creatures were dead in the water treated by 10×10^(-6) of the efficient chlorine, and it can transfer algae after killing the harmful creatures by using bleaching powder when there was reserve water.
