利用聚硅硫酸铁这一新型无机高分子絮凝剂在炼钢厂除尘废水处理中可起到较好的应用效果,经试验结果证实,聚硅硫酸铁絮凝剂本身的应用剂量和所进行处理的废水酸碱值是对最终絮凝效果产生影响的主要因素,而温度因素的影响不大。在废水的p H值为6.0,且聚硅硫酸铁絮凝剂的应用量为0.25ml/L之时,废水混浊度、表层悬浮物的去除率达到了95.42%。
The use of polysilicate ferric sulfate inorganic inorganic flocculant in the steel mill dust removal wastewater treatment can play a good effect, the test results confirmed that the application of polysilicate ferric sulfate flocculant dosage and the processing The pH value of wastewater is the main factor affecting the final flocculation effect, but the influence of temperature factor is not significant. When the p H value of wastewater was 6.0, and the application amount of polysilicate ferric sulfate flocculant was 0.25ml / L, the turbidity of wastewater and the removal rate of surface suspended solids reached 95.42%.
