利用硫酸矿灰研制了一种ＦＨ复合混凝剂，用于硫化染料废水，活性染料废水及混合印染废水处理，试验表明：脱色率＞９０％，ＣＯＤ去除率约为６０％～７０％。其效果不亚于ＰＡＣ，但投药费可降低约３０％，工程投资低于应用ＰＡＣ。
A kind of FH composite coagulant was developed by sulfate mineral ash for the treatment of sulfur dye wastewater, reactive dye wastewater and mixed printing and dyeing wastewater. The experiment shows that the decolorization rate is more than 90% and the COD removal rate is about 60% -70%. Its effect is as good as that of PAC, but the cost of medicine can be reduced by about 30%, and the investment in construction is lower than that of PAC.
