摘　　要：以受污染地表水和曝气池出水为研究对象,考察了三氯化铁(FC)和聚合氯化铝铁(PFAC)的除磷效果及对出水pH的影响。结果表明:总磷(TP)去除率随着药剂投加量的增加而提高;药剂投加量相同时,三氯化铁对TP的去除率明显高于聚合氯化铝铁,但三氯化铁是对出水pH影响要大于聚合氯化铝铁。The Phosphorus removal effect of ferric trichloride（FC） and PFAC was studied in this paper with polluted surface water and effluent of Aeration tank as the objects of experiments,the change of pH value was also investigated.The results showed that the removal rate of total phosphorus（TP） increased with the dosage of FC and PFAC increased.The removal effect of FC is better than PFAC,however,compared with PFAC,the FC have more effects on the pH value of the effluent.

关 键 词：化学除磷 三氯化铁 聚合氯化铝铁
