为了提高废弃泥浆的压滤脱水效率，选用PAM作为絮凝剂，采用物理-化学联合的方法，研究不同类型、不同分子量和不同加药量对钻孔粘土泥浆压滤脱水性能的影响规律。试验结果表明，阴离子型PAM絮凝剂能明显改善钻孔粘土泥浆的脱水性能；相对分子量为1000万的阴离子型PAM絮凝剂效果最优，并确定不同加药量对钻孔粘土泥浆压滤脱水的影响规律；在此基础上建立最优PAM絮凝剂压滤脱水的数学模型，为指导钻孔粘土废弃泥浆的处理提供一定的参考价值。

In order to improve the filter press dewatering efficiency of waste mud , PAM was selected as floccu-lant.The influence of PAM with different kinds, different molecular weights(MW) and different doses on the fil-ter press dewatering performance of drilling clay mud was studied by the physical -chemical method .The re-sults was studied .The results showed that anionic PAM ( APAM) flocculant improves the drilling clay mud de-watering performance.The optimal flocculant is APAM with MW of 10 MDa, and the influencing rule of different doses on the filter press dewatering performance of drilling clay mud was determined .On the basis of the above results the mathematical model of optimal PAM filter press dewatering flocculant was established , which provides some reference to guiding drilling waste mud clay processing .
