摘要
本文研究了絮凝剂类型、絮凝剂用量和渣浆浓度等对中和渣浆沉降性的影响。结果表明:选用PAM-3、用量在7.5mg/L,其絮凝沉降效果相当于现场使用的PAM-1 10mg/L,每年可节省药剂成本约13.87万元;中和渣浆的絮凝沉降过程符合Hill1方程,沉降速率呈先增后减的趋势。
The effects of flocculant type,flocculant dosage and slurry concentration on the settling performance of neutralization slugde were investigated.The results show that when the dosage of PAM-3 is 7.5mg/L,the settling performance is similar to the PAM-1 with lOmg/L,which was used in plant,and the cost of agent would be reduced about 138.7 thousand RMB annually.The settling process of slurry conforms to the form of Hilll equation,the settling velocity increases firstly,and then decrease.
