摘要
本文对电凝聚除铁机理进行了探讨。在电凝聚器中，Ａｌ３＋离子的水解产物吸附Ｆｅ２＋离子后，通过沉淀、过滤工艺而除铁。它不需要对Ｆｅ２＋离子进行充分氧化，并克服了常规除铁工艺初期出水不能满足国家饮用水卫生标准的缺点。试验结果表明：电凝聚除铁有效果好、操作简便。
The paper discusses the theoretical basis of the electric coaguation used in iron removal. According with the adsorption theory, Fe 2+ needs not to be fully oxidized to Fe 3+ , and the equipment can improve water quality during initial treatment. As soon as the equipment is put into operation, the quality of treated water will reach the water quality standard.
