摘要
深井超深井聚磺钻井废水具有高色度、高悬浮物和高COD的特点,现有的物化处理技术存在的吸附剂再生困难、水处理剂用量大的缺陷。采用生物降解和膜分离技术,室内研究了物化-生物协同工艺的处理效果,并在川东北高酸性气田大湾404-1H和元坝222等井开展了现场实验。实验结果表明,处理后的水质全部达到《污水综合排放标准》(GB8978-1996)的一级标准。
Polysulfonate drilling fluid wastewater of deep wells and ultra-deep wells was treated through Physical and chemical techniques usually. But there were some drawbacks such as difficult adsorbent regenera- tion and too much consumption of water treatment agent since chroma, suspended solids content and COD of the wastewater were high. Microbial degradation and membrane separation technology were used. Effects of wastewater treatment were evaluated through experiments indoors and tests in Dawan 404-1H and Yuanba 222 high sour gas wells of Northeast Sichuan fields. The application results showed that the treated waters achieve the first standard of Sewage Comprehensive Discharge Standard（GB8978-1996）.
