摘　　要：某钢厂综合污水处理厂来水类型复杂、多样,为使混凝预处理后水质达到后序超滤膜单元进水要求,延长超滤膜系统使用寿命,针对两种不同来水水样进行了PAC和PAM混凝实验,确定了最佳药剂投放比例,黑红色水样最佳投药比例为25mg/L PAC和2mg/L PAM,黑灰色水样最佳投药量为25PAC和1.5mg/L PAM。The types of water samples are complex and diverse at a comprehensive sewage treatment plant of steelmaking plant.The PAC and PAM coagulation experiments were carried out for two different water samples,in order to make the water quality to meet the inflow requirements o£the post-sequency ultrafiltration membrane unit after coagulation pretreatment and prolong the service lifetime of ultrafiltration membrane system.The optimal dosage ratio is confimied.The best dosage ratio of black-red water sample is 25mg/L PAC and 2mg/L PAM,and the best dosage ratio of black-grey water sample is 25PAC and 1.5mg/L PAM.
