摘　　要：研究高密度泥浆法（HDS）处理工艺和最佳运行参数。结果表明,在控制pH值为10.0、PAM投加量为3mg/L左右、反应时间为30min、沉淀时间为25min、底泥回流比10-20∶1,除氟剂Al2（SO4）3的投加量为0.66g/L时,出水水质满足广东省地方标准（DB44/26-2001）中的一级标准的要求。运行费用约为0.45￥/t,较石灰中和法降低10%-15%,处理能力提高50%以上,是传统石灰中和法的先进适用替代工艺。The technology and optical technical parameters of lead and zinc smelting comprehensive waste water treatment with high density sludge（HDS） method are investigated.The results show that under optimal condition of pH=10,PAM dosage 3mg/L,reaction time 30min,sedimentation time 25min,sludge reflux ratio10-20：1 and Al2（SO4）3 dosage 0.66g/L,the effluent quality meets the first class requirements of DB44/26-2001.Operating cost is 0.45 ￥/m^3 that are 10%-15% lower than that the lime neutralization method.The treatment capacities of HDS process are higher than that lime neutralization method by 50% , and HDS process is a very good alternative technology for lime neutralization method.
