摘　　要：废钻井液是一种组分复杂的胶体悬浮液,对地下水源及完井后复耕影响较大。因此,对其固化处理极为关键。以工业废渣粉煤灰、磷肥、聚合铝及MgCl_(2)、CaCl_(2)的混合物为固化原料对废钻井液进行正交实验研究,通过对不同处理剂添加量处理后污染物浸出浓度进行检测,再对测得的正交实验数据进行直观分析和方差分析,最终确定废钻井液处理剂的最佳配方。废钻井液固化处理是目前国内最为普遍的一种处理方法,其对环境保护和废物再生利用具有重要意义。Waste drilling fluid is a kind of colloidal suspension with complex components,which has great influence on underground water source and second ploughing of post-well.Therefore,curing treatment is very critical.Using industrial waste slag fly ash,phosphate fertilizer,polyaluminum,MgCl_(2)and CaCl_(2)mixture as solidified raw materials,orthogonal experiment is conducted on waste drilling liquid.Through the detection of pollutants′leaching concentration after treatment with different additive amounts of treatment agents,and the intuitive analysis and variance analysis of the orthogonal experimental data,the optimal formula of treatment agents for waste drilling fluid is finally determined.Solidification treatment of waste drilling fluid is one of the most common treatment methods in China,which is of great significance to environmental protection and waste recycling.
