Research on Salt Mine Drilling Waste Mud Treatment Technology and Engineering Application
摘要
Abstract
For the purpose of harmless treatment of drilling waste mud from a salt mine at Da'an town in Guangan city of Sichuan province,the treatment process including pretreatment,gel breaking,solidification,construction of harmless treatment and harmless exit,was designed.The results show that:(1) Polyferric aluminum chloride (PFAC) was found to be the best gel breaker,is was more effect than FeCl3,PAC and Al2 (SO4) 3;(2) After gel breaking,the average effluent COD concentration was 6.48 mg/L with corresponding degradation rate of 99.41％,and the optimal pH was 6 ～ 7;(3) Through harmless construction and exit,the drilling waste mud solidification had met the requirement of safety and harmless.This study not only solved the problem of drilling waste mud pollution in the salt mine in Daan Town,but also effectively improved the local environmental quality.关键词
