摘要
印染废水的治理是我国现行工业废水治理领域的几大难题之一。本文以三种单体染料为研究对象,对絮凝剂聚硅酸铝铁进行改性,并对其脱色效果进行了检验。通过正交试验找出影响脱色效率的主要因素,并找出最佳配方组合。实验表明,改性聚硅酸铝铁脱色效率高,沉速快,是一种具有很好应用前景的脱色絮凝剂。
It was proved that dyeing wastewater is difficult to be treated using normal coagulant as well as PSAFS.This article introduces the preparation of modified PSAFS for dyeing wastewater treatment.Perpendicular experiments(L9(34)) were carried out.The main factors and the optimum conditions for preparing modified PSAFS was found. It proves that the discoloring efficiency preponderate over 90 percent using modified PSAFS for dyeing wastewater treatment.
