摘　　要：以Al-Fe混凝荆、聚丙烯酰胺（PAM）、十六烷基三甲基溴化铵（CTAB）为助凝剂，考察了水溶性膦配体间磺酸钠基三苯基膦（TPPTS）废水中化学耗氧量（COD）的去除率，以此来间接考察TPPTS的去除效果。结果表明，助凝剂的添加能提高COD的去除率。获得了化学耗氧量COD 1000～1500mg／L废水除膦的优化条件：pH=5．5，Al-Fe、CTAB、PAM的投加量分别为300mg／L、67mg／L和21mg／L时，COD去除率达92．9％。The removal of TPTS [P（m-C6H4SO3Na）3 ] in wastewater was tested indirectly by testing that of its chemical oxygen demand （COD） when Al-Fe flocculant, polyacrylamide （PAM） and cetyl trimethylammonium bromide （CTAB） were used as coagulant. The results showed that addition of coagulant could enhance the removal effect of COD. The optimum conditions of phosphine removal in wastewater with COD of 1000 - 1500 mg/L were obtained as pH =5.5, the dosage of Al-Fe flocculant, CTAB and PAM were 300, 67 and 21 mg/L, respectively. The COD removal reached up to 92.9%.
