使用漂白粉改善对虾池水环境的研究１．漂白粉杀菌效果试验漂白粉在过滤海水与生理盐水中的杀菌率基本一致。当有效氯浓度为０．２～０．５ＰＰｍ时，其杀菌率为９３～９７％．杀菌率受水中有机质含量的影响较大，有机质含量越高，杀菌效果越差。２．漂白粉对对虾的毒性试... Study on improving the water environment of shrimp pond using bleaching powder 1. Bleaching powder bactericidal effect test Bleaching powder in the filtered seawater and saline sterilization rate is basically the same. When the effective chlorine concentration of 0.2 ~ 0.5PPm, the sterilization rate of 93 to 97%. The sterilization rate is greatly affected by the organic matter content in the water. The higher the organic matter content, the worse the bactericidal effect. 2. Bleach on shrimp toxicity test ...
