摘要
随着地下工程的发展,钻孔废弃泥浆含水量高不易处理,所以废弃泥浆脱水的研究很有必要.主要探讨了复合絮凝剂(石灰、石膏、粉煤灰和高分子絮凝剂4种材料组成)对废泥浆脱水性能的影响,并安排了纯有机高分子絮凝剂和复合絮凝剂的对比试验,运用先絮凝后压滤的方法解决了废泥浆脱水问题.试验表明复合絮凝剂比高分子絮凝剂具有更好的絮凝脱水效果,并通过正交试验获得了复合絮凝剂各成分最佳掺量.为复合絮凝剂在废弃泥浆脱水中的应用起一定的指导作用.
With the development of underground engineering, it is not easy to handle the problem of low water content in waste drilling mud, so research on its dehydration is necessary. Experimental method of first flocculation and then pressure filtration is used to study the rule of slurry dewatering rate with a mix of PAM lime, gypsum and fly ash as flocculant in the discarded slurry. And contrastive test was conducted between the pure organic polymer flocculant and composite floeculant of. Result shows that the complex flocculant is better than PAM on dehydration. Quadrature experiment finds out the optimal dosage of every kinds in the complex flocculent, which plays a role of guidance on its application in waste mud dehydration.
