| 摘 要： | 以聚铝(PAC)为参照比较研究了聚合氯化铁(PFC)在微絮凝深床过滤工艺中的应用效果.结果表明PFC投药量少(Fe:Al=3:5),其水头滤程可达63h,周期产水率可达1504m3/m2,而PAC的水头滤程为53h,周期产水率为1266 m3/m2;PFC表现出利于延长运行周期,提高产水率等优势.通过截污机理研究表明,PFC具有形成絮体快,与滤料作用迅速,脱水性能好等特点,与PAC相比PFC更适用于微絮凝-深床过滤工艺.

| Abstract: | Compared with polyaluminium chloride (PAC), the application efficiency of polyferric chloride (PFC) were investigated by pilot micro-flocculation deep bed filtration. The results show that, under the condition of lower dosage (Fe:Al = 3:5), the headloss cycle of PFC was 63 h, and its output in a cycle was 1504 m3/m2, but PAC headloss cycle was 53 h with its output 1266 m3/m2. It is concluded that PFC was benefit to prolong operation cycle and improve output. The research on particle removal mechanism shows that PFC could enhance the floc growth, and the PFC flocs could be effectively entrapped and dehydrated. Therefore PFC is more suitable for the micro-flocculation deep bed filtration process than PAC. |
