聚丙烯酰胺在硫酸污水处理中的应用

Application of polyacrylamide to the treatment of wastewater from sulphuric acid

分析了经电石渣法处理后的硫酸污水悬浮物排放浓度的影响因素 ,通过对阴离子型聚丙烯酰胺絮凝剂的絮凝试验 ,确定了在硫酸污水处理中使用聚丙烯酰胺 (PAM )合适的剂量及絮凝工艺 ,并得到实际应用。应用后改善了硫酸污水的沉降性能 。

Affecting factors on the effluent concentration of suspended substances in sulfuric acid wastewater after treated with carbide slags are analyzed. Through flocculation tests on anionic polyacrylamide flocculant,proper amount of PAM used in sulfuric acid wastewater treatment and flocculation process are fixed and applied in practice. Its use improves sedimentation performance of sulfuric acid wastewater,thus improving the discharge quality of suspended substances.
