摘要
提出利用有机改性黏土矿物为絮凝材料,以天然海水模拟船舶压载水进行絮凝处理有害生物的方法.当有机改性黏土用量为0.10 g/L时,可以去除海水中100%的细菌和85%的浮游植物,对部分原生动物也有很强的灭杀作用.该方法具有成本低廉、使用安全有效、环境可接受等优点,具有用于船舶压载水有害生物治理中的可行性.
The synthesized organoclay is applied to remove the plankton and microorganism from ballast water. The experiments indicate that 100% bacteria and 85% phytoplankton could be killed when the content of the organoclay reaches up to 0.10 g/L. This function can be also useful to exterminate some protozoa in water. The method using organoclay flocculation treatment is cheap, environmentally acceptable and of lower dosage. As a feasible and effective method, it is prospected to be applied to treat the harmful organisms in ships＇ ballast water.
