摘要
采用自制新型氧化混凝药剂——无机氧化性高分子硅铁混凝剂(PSF)对腈纶废水生化出水进行处理,并与聚合硫酸铁、聚合氯化铝的混凝效果进行对比试验;以出水COD去除率为评价指标,通过单因素试验优化确定出适宜条件。结果表明,在初始pH为9、CaO投加量为1.0 g/L、PSF和聚丙烯酰胺投加量分别为900、6 mg/L的条件下,出水COD去除率可达到30%以上。采用PSF新型混凝剂可以有效去除腈纶废水生化出水中的溶解性大的难降解有机污染物,效果明显优于其它2种混凝剂,可以作为腈纶废水深度处理的一种新型预处理药剂。
Self-made new type oxidation coagulating agent-inorganic oxidizing polymer silicon iron flocculant（PSF） was used to treat the biological effluent of acrylic fiber wastewater.Through comparison testing of coagulation effect of PFS and PAC.When using the effluent COD removal rate as the evaluation index,the single factor test optimized and determined the best test condition.The results showed that： in the initial pH was 9,CaO dosage was 1.0 g/L,oxidation and coagulant dosage was 900 mg/L,PAM dosage was 6 mg/L condition,the effluent COD removal rate can reach 30% or more.PSF new type coagulating agent can effectively remove the acrylic fiber wastewater effluent solubility of refractory organic pollutants,The effect is obviously superior to the other two coagulant.it can be used a new pretreatment agent to treat deeply acrylic fiber wastewater.
