摘要
以煤系高岭石为主剂,氧化钙为助剂,酸浸一步合成聚合氯化铝铁(PAFC).并以黄河水为原水,通过与市售聚合氯化铝(PAC)做絮凝对比试验,取得了良好的絮凝效果.而且原水的pH值为5—9,去浊率达到99%以上.
Through the measure of advanced test including polycrystal X-ray diffraction, differentical thermal analysis, transmission electron microscope and so on, we determined the coal-serial kaolinite for the major reagent after analyzing its constitution, topography, composition and phase transition etc. Calcium oxide is subsidiary reagent. The synthesis method of polyaluminum ferric chloride adopted the singlestage process of acid pickling. We adopt the orthogonal experiment of five factor and four level, having seeken for the agreeable reaction condition. Chemical analysis fixes on the composition and ability of product. The pattern of infrared spectra determines the position and connect style of hydroxyl. Making a good result in the flocculating experiment, the turbid rate is more than 99% when the pH of original water（ the Yellow river water）is between 5 and 9.
