一、产品说明
中文名称:聚合硫酸铁(简称聚铁)
英文名称:Poly Ferric 缩写为PFS
分子式:〔Fe2(OH)n(SO4)3--n/2〕m,n <2,m>10,m=f(n)
二、产品性能和用途
聚合硫酸铁按状态分为I和II型,I型是红褐色粘稠透明液体,英文缩写为L.PFS;II型是淡黄色无定型粉状固体,英文缩写为S.PFS,有较强的吸湿性,聚合硫酸铁是一种高效无机高分子混凝剂,分子量高达1 ×105无毒无害,化学性质稳定,能与水混溶,在水处理过程中,聚铁能很快水解形成大量的阳性多核络离子,中和胶体微粒表面电荷,强烈吸附胶体微粒,通过粘附、架桥、交联、卷扫作用,使微粒凝聚形成絮体而沉降,从而使水净化。
聚合硫酸铁凝聚性能好,沉降速度快,适应PH值范围广,同时还具有脱色、除臭、去除重金属离子,显著降低COD、BOD 等效果。因此广泛用于城镇生活饮用水、工业循环水的净化处理,以及化工、石油、矿山、造纸、印染、酿造、钢铁、煤制气、电镀等行业的工业废水和城市生活污水的净化处理,对不同的地区不同种类源水都能达到理想的净化效果。

四、使用方法
1、使用时,应先根据处理水量,源水性质、浊度和加药方式及工艺等配制相应浓度的聚铁药液。一般将I型
(L.PFS)配成10%-30%的水溶液。在源水浊度较高、水处理量较大时,配成50%-100%的水溶液。将II型
(S.PFS)配成5%-20%的水溶液。
2、在搅拌的同时加入稀释后的药液。
3、经过混凝沉淀、过渡后,可得到澄清的出水。
具体投加量,应根据实验数据确定。处理饮用水L.PFS原液节约消耗量参见下表。

200-500 | 8.0-11.0 |
500-800 | 11.9-16.5 |
900 | 17.9 |
1000 | 19.2 |
1000以上 | 根据实际情况投加 |
1000以上 | 根据实际情况投加 |
五、注意事项
1、聚合硫酸铁必须在较强酸性条件下才能稳定(L.PFS原液PH值0.5-1.0),运输、储存、配液和加药设备必须
使用耐酸材料或做防腐处理。
2、聚合硫酸铁在配液时酸性降低,PH值升高,当PH>3,浓度约为1%时,Fe較容易形成难溶的Fe(OH)3黄色沉淀物
。因此,聚铁的配制浓度不应低于5%,而且配制好的溶剂不要储存时间过长,最好在24小时内用完。
3、对一些酸性较强PH<5或碱性较强PH<11的源水,应先用PH调节剂调节PH值在7-10间(聚铁最佳应用范围),
再投加聚铁,进行混凝。
4、在使用II型(S.PFS)聚铁时,因其吸湿性较强,应尽量做到开包即用,但即使吸潮变形也不会影响其使用效
果。
5、如地面或衣物溅有聚铁斑迹,可用少量的草酸溶液浸洗。
六、包装和储运
聚合硫酸铁I型(L.PFS)包装成为25kg聚乙烯塑料桶或玻璃钢槽车;II型(S.PFS)采用双层袋包装,内袋采用食
品级聚乙烯薄膜袋,外包装采用塑料编织袋,每袋净重25kg。
聚合硫酸铁应储存在通风的库房内,不要暴晒,I型(L.PFS)应储存于耐酸溶器中环境温度不低于-20℃,II
型(S.PFS)有效储存期为2年,运输时要避免暴晒、雨淋受潮,避免撞击、泄漏、腐蚀,避免有毒物质污染。
