铁碳微电解-Fenton氧化处理海上废弃钻井液液相实验
摘要
Abstract
To protect ecological environment of Bohai gulf, waste drilling fluid must be disposed in offshore oilfield. Fe/C microelectrolysis-Fenton oxidation method was investigated for the wastewater of organic positive gel drilling, which was applied widely in Bohai bay oilfield. The influence of reaction time to microelectrolysis, the dosage of H2O2 and reaction time to Fenton reaction are investigated. The optimal conditions of the treatment were determined as follows: reaction time 3 h for microelectrolysis method, while the dosage of hydrogen peroxide 0. 5%, and reaction time 120 min for the Fenton method. Because of high COD value of wastewater, treatment by Fe/C Microeletrolysis-Fenton oxidation cannot meet the requirement of discharge standard. Process integration of Fe/C Microeletrolysis-Fenton oxidation-sodium hypochlorite can decrease the COD value of wastewater significantly. After process of Fe/C Microeletrolysis-Fenton oxidation-sodium hypochlorite, multi-time treatment can meet secondary discharge standard by process integration of Fe/C Microeletrolysis-Fenton oxidation.关键词
