摘要
通过对涂铁砂 (Fe -CS)和未涂层石英砂 (US)的过滤对比试验 ,对Fe -CS去除有机物的规律进行了探讨 ,同时对Fe -CS去除有机物的影响因素 (空床停留时间EBCT、进水有机物浓度、pH值、Ca2 + 浓度等 )进行了试验研究 ,并提出了Fe -CS的再生方法。
By carrying out comparison tests on filtration with iron coated sand (ICS) and uncoated sand (US) as media, removal of organic matter by ICS filtration was studied. Some factors influencing the removal of organic matter with ICS filtration, such as empty bed detention time, influent concentration of organic matter, pH, Ca 2+ concentration were investigated. A method for ICS regeneration was also put forward.
