摘　　要：为解决石矿废水浊度大和固体悬浮物粒度细的问题,通过单一有机絮凝剂、无机絮凝剂、调整剂种类用量、药剂组合优化试验对该废水开展高效净化研究。结果表明,在调整剂CaO用量为200 g/m^(3),无机絮凝剂聚合氯化铝(PAC)用量为2.5 g/m^(3),有机絮凝剂PAM-新用量为12 g/m^(3)组合用药条件下,废水浊度为97.30 NTU,满足废水“零排放”生产回用要求和工业废水排放标准。In order to solve the problem of large turbidity and fine particle size of suspended solids of quarry wastewater,efficient purification experiments were conducted on this wastewater with single organic flocculant,inorganic flocculant,regulator type and dosage,and optimizing agent combination.The results showed that under the combined reagents of regulator CaO 200 g/m^(3),inorganic flocculant PAC 2.5 g/m^(3),and organic flocculant PAM-new 12 g/m^(3),the wastewater turbidity was 97.30 NTU,which met the wastewater"zero discharge"production reuse requirements and industrial wastewater discharge standards.
