摘要
根据云南腾冲科学钻探废弃钻井液的特点,确定了先絮凝破胶再固化的技术路线,筛选出絮凝破胶预处理及固化的最优配方。实验结果表明,固化效果良好,经絮凝沉降后分离出的废水、固化物浸出液污染物含量均达到污水综合排放一级标准。
According to the characteristics of waste drilling fluids of Tenchong scientific drilling project in Yunnan,the technology route of first flocculation and gel breaking then consolidation was determined,the optimal formula of flocculation and gel breaking pretreatment and solidification were screened out.The experimental results show that the solidification effects are good,the pollutnats contant in the separated waste water after flocculation sedimentation and leaching solution of cured resin meet the 1st grade integrated wasterwater discharge standared.
