摘　　要：采用传统的铁盐作净水剂,用NaOH调节pH值在7.0左右,生成Fe(OH)_3和Cr(OH)_3沉淀,加入阴离子表面活性剂,利用沉降达到处理含铬废水的目的。治理结果:沉降速率快,去除率达99％,Cr^(6+)浓度远低于0.5mg/L。In this paper,traditional iron salt was used as purifying water agent,pH was adjusted to about 7 with NaOH and Fe(OH)3 and Cr(OH)3 sedimentation were produced,then are that negative ion surfactant was added to,achieve the aim of treating waste water of inclusion - Cr with sedimentation. The treating result: the rate of sedimentation is fast, the rate of removing reachs 99% ,the consistency of Cr6+ is far below 0.5mg/L.
