, 2019 蓝藻水华是水体富营养化破坏性灾变的表现之一,其治理一直是国内外的研究热点。受限于水华蓝藻广泛的尺寸分布,机械过滤作为水中悬浮颗粒的去除手段尚未在水华治理中推广。微囊藻是水华蓝藻中常见的优势种,絮凝可使其形成较大尺寸的絮体,有利于机械过滤设备将其去除。通过比较不同尺寸絮体的叶绿素a浓度,可以考察聚合硫酸铝、聚合硫酸铁、聚合氯化铝、聚合氯化铝铁对微囊藻机械截留效果的影响。结果表明,絮凝效果PFS>PAS>PAC>PAFC,200 mg/L PFS的絮体有92.26%可被250μm滤网截留,97.55 ...

, 2018 淀粉改性阳离子型絮凝剂具有无毒、价廉、高效以及可生物降解等优点而被广泛关注。该研究首先采用正交法对其制备条件进行了优化,并利用该制备材料在不同条件下进行了野外蓝藻的絮凝优化实验。结果表明：当2,3-环氧丙基三甲基氯化铵（GTA）与淀粉用量比例为1∶5,中火微波条件下合成的阳离子淀粉絮凝效率最佳。在富营养化水体中,最佳的絮凝条件为：搅拌速度在120 r/min以上,搅拌时间在0.5-4 min范围内时,絮凝效率可高达90%以上,且p H在5-9范围内对絮凝效率无影响 ...
