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.
