, 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 ...

Effects of organic matter, CaCl_2 and MgCl_2 on flocculation and settling of fine sediment.
, 2001 在CaCl2和MgCl2浓度为0~1.0mmol/L,泥沙浓度为10g/L时,用吸管法研究了有机质、CaCl2和MgCl2对细颗粒泥沙静水絮凝沉降的影响,结果表明,去除有机质后,细颗粒泥沙絮凝沉降加快,其絮凝所需的最佳电解质浓度降低;CaCl2和MgCl2的絮凝能力无明显差异,有机质含量对其几乎没有影响;在相同盐度下 ...

Effect of CaCl_2 on Fine Sediment Flocculation and Settling in Still Water
, 2000 细颗粒泥沙的絮凝或分散对土壤渗透性、土壤可蚀性有重要作用 ,是水土保持研究的重要内容。在 Ca Cl2 浓度为 0～ 1.0 mmol/L ,泥沙浓度为 10 g/L时 ,用吸管法研究了 Ca Cl2 对细颗粒泥沙絮凝沉降的影响。结果表明 :泥沙沉降分 2个阶段 ,分选沉降段和絮凝沉降段 ;在絮凝沉降段 ,Ca Cl2 浓度越大 ,絮凝沉降越快。但较高浓度时 ,细颗粒泥沙平均沉速反而随 Ca Cl2浓度增大而逐渐减小 ;泥沙浓度随时间呈指数衰减 ;细颗粒泥沙絮凝临界粒径为 0 .0 ...
