絮凝预处理对微囊藻机械过滤的影响

, 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 ...

介绍一种过滤蒸馏水的简易装置

Huli yanjiu, 1991
1989年2月,我们以价值仅有300元左右的器材设备成功安装了过滤蒸馏水简易装置,所滤过的蒸馏水经各种检验,其质量均达到中国药典规定,保证了供应室的正常工作,现将基本情况介绍如下: 一、作用原理 利用陶瓷矿蕊滤棒上的许多微孔,使蒸馏水由微孔渗透到滤棒内,再通过电动吸引器形成的负压,将滤棒中的蒸馏水吸至收集瓶中备用。如此除去了原蒸馏水中的杂质,保证了过滤蒸馏水的质量要求。 二、过滤系统所需器材 1、电动吸引器一台。（如供应室设有皮管过滤器,则该装置上的吸引器可利用）“Y”型接管连接,供两套装置使用 ...
