研究了沸石载铜(FZT)作为除藻剂对赤潮生物的灭杀和控制作用.结果表明,FZT能缓慢释放铜离子对海洋原甲藻有去除作用,延长了有效期,增强了除藻能力,并减轻了直接投放硫酸铜造成局部铜离子浓度过高而伤害鱼类的缺点.加入铁盐增效剂可提高除藻剂的除藻效果,减少除藻剂的用量. The effects of FZT as algaecide on killing and controlling red tide organisms were studied.The results showed that the release of copper ions by FZT could slow the removal of marine procambium, prolong the expiration date and enhance algae removal ability, And reduce the shortcomings of direct copper sulfate concentration caused local copper ion concentration is too high and harm the fish.Add iron salt synergist can increase algaecide algae removal effect and reduce the amount of algaecide.
