摘要：

　为提高混凝剂对印染废水的处理效果,用煤矸石和硫铁矿烧渣作原料制备一种无机高分子混凝剂聚硅酸铝铁(PSAF) ,并将其用于印染废水的处理。结果表明: pH 值为6～9 范围内,PSAF 混凝剂对印染废水有很好的处理效果;在常温,pH 值为712 ,PSAF 混凝剂质量浓度为75 mgPL 的条件下,SS、色度及CODCr的去除率分别为9411 %‘8816 %和8112 %;与传统混凝剂PAC(聚合氯化铝) 和PFS(聚合硫酸铁) 相比,PSAF 混凝剂具有混凝沉降速度快,污泥体积小,处理废水后水中残余量低,处理费用低等特点

Abstract: A new type of inorganic polymer coagulant polysilicate aluminiumferric (PSAF) was prepared from
coal gangue and pyrite slag and used as coagulant in the treatment of dyeing effluent , aiming at improving the
treatment effect of dyeing effluent with coagulant . The experimental results showed that PSAF had a good
coagulation effect in the treatment of dyeing effluent under the pH value ranging from 6 to 9. The removal rate
of SS , colority and CODcr was 9411 % , 8816 % and 8112 % respectively under such conditions as room
temperature , pH value = 712 and dosage of the coagulant 75 mgPL. In comparison with the conventional
coagulants , such as PAC (polyaluminium chloride) and PFS (polyferric sulfate) , the coagulation performance
of PSAF is characterized by higher settlement rate , smaller sludge volume , lower remains of pollutants in the
treated dyeing effluent and lower cost of treatment
