摘要
以完全去除类似隐孢子虫等微粒子为目标,实验选用与隐孢子虫外观尺寸相似的Crypto-tracer-1号示踪微粒子,对金属膜过滤系统在饮用水中的处理性能进行评价和研究.试验选用三种金属膜:金属薄片筛网膜过滤器(Fuji FP-0.3),金属非织网式膜过滤器(Fuji FA-3),金属粉末烧结膜过滤器(SIKA-R0.5AS).试验对金属膜处理工艺中的水质参数和膜间压力进行测试分析,结果表明,在大规模的给水处理厂中,采用金属膜过滤系统可以在高滤速下完全将类似于隐孢子虫微粒子去除.
The purpose ofthis study is to completely remove cryptosporidium particles etc. in raw waters by employing metallic membrane filtration system. Three kinds of metallic membranes, including Laminating metal mesh filter (Fuji FP- 0.3), Non-woven metal filter (Fuji FA- 3) and Sintered metal fibre filter (SIKA- R0.5AS), were applied to the experiment to evaluate water quality and membrane trans-pressure. The Crypto-tracer-1 with the similar size as C. parvum particle was added in the raw water of the experiment. The results show that C. parvum-like particle can be completely removed with the metal membrane filtration systems under high flux.
