利用机械力化学法活化固硫灰固化降解含油钻屑,研究了不同含油钻屑掺比对固化降解效果的影响,并进一步探讨了机械力化学法对含油钻屑中有机污染物的固化降解机制。研究表明,当含油钻屑掺量为50%时,球磨后样品中的含油率为1.92%,固化体常温养护28 d抗压强度为22.70 MPa,固化体石油类浸出浓度为3.875 mg/L低于GB 8978-1996中规定的限值。XRD分析表明含油钻屑中的有机污染物以物理包裹和吸附的形式被固化于含油钻屑固化体的凝胶相中。IR分析表明机械力化学法对含油钻屑中的有机污染物有较好的降解作用。
The mechanochemical method was used to activate solidified sulfur ash to solidify and degrade oil-bearing drill cuttings. The effect of different oil-bearing cuttings mixed ratio on solidification and degradation was investigated. The mechanism of mechanical chemical degradation of organic contaminants in oil- . The results show that when the content of oil-bearing cuttings is 50%, the oil content in ball-milled samples is 1.92%, the compressive strength at room temperature for 28 days is 22.70 MPa and the solidified oil is 3.875 mg / L Limits specified in GB 8978-1996. XRD analysis showed that organic contaminants in oil-bearing cuttings were physically encapsulated and adsorbed onto the gel phase of the oil-cut cuttings. IR analysis shows that mechanochemical chemistry has a good effect on the degradation of organic pollutants in oil-bearing cuttings.
