Abstract:

褐潮是一种由微微型藻引发的藻华,已连续4年在渤海海域暴发,给当地带来巨大的经济损失。目前,在褐潮尚不能有效预防、预控情况下,如何控制和减少其对生态环境和沿海经济带来的危害,成为一个急需解决的问题。利用改性黏土消除藻华是一种快速有效、并得以多次现场成功应用的方法。考察比较了多种不同产地、不同类型的黏土及其改性后对褐潮生物种Aureococcusanophagefferens(抑食金球藻)的去除效果,选取5种典型的黏土作为主要的实验材料,开展了不同条件下黏土及其改性后对A.anophagefferens去除效率的影响研究。实验发现,因A.anophagefferens个体微小、藻华时密度大,相同用量的黏土或改性黏土对其去除效率低于常见的硅藻、甲藻生物;不同类型黏土对其去除效率有影响,高岭土的去除效率高于蒙脱土;而黏土改性后对A.anophagefferens的去除效率提高3倍以上。在此基础上,还考察分析了黏土粒径、分散介质等因素对A.anophagefferens去除效率的影响,为进一步研发安全、高效的褐潮应急消除材料做了有益探索。
