在油田的勘探和开发中,井场上往往留下大量的钻井废液及岩屑露天堆放．这些钻井废液中含有许多危害周围环境的有害组分(如高聚物、重金属离子、油类等),它们通过扩散、渗漏、溢出、淹没等各种方式污染水源,危及周围农田农作物和水生生物的生长,甚至影响到周围居民的身体健康．根据对已有的资料分析,新疆吐哈钻井废液的主要污染指标(ＣＯＤ、悬浮物、ｐＨ、挥发酚、
In the exploration and development of the oilfield, a large amount of drilling waste liquid and debris are often left on the wellsite in open storage. These drilling fluid waste contains many harmful components (such as polymers, heavy metal ions, oil, etc.) that harm the surrounding environment, which pollute the water source through various ways such as diffusion, leakage, overflow and inundation, endanger the surrounding farmland crops and The growth of aquatic organisms may even affect the health of the surrounding residents. According to the analysis of existing data, the main pollutants (COD, suspended solids, pH, volatile phenol,
