生化—电催化氧化—炭吸附工艺处理水基泥浆压滤液
Biodegradation-electrocatalytic oxidation-carbon adsorption treatment of water-based drilling mud filtrate
摘要
Abstract
A biodegradation-electrocatalytic oxidation-carbon adsorption combination process was used to treat the water-based drilling mud filtrate.COD was used as the main indicator,and other pollutants were used as auxiliary indicators.The removal process of organic matter was analyzed by GC-MS and FTIR,and elemental changes were analyzed by XRF.The characterization results show that most organic matters can be removed by this combination process,but cis-7-tetradecyl acetate,3-amino-6-methylpyridin-2(1H)-one,and 2-decylthiophene are organic matters that are difficult to be removed by this combination process.The experimental results show that COD in the effluent of the water-based drilling mud filtrate treated by this combination process is less than 50 mg/L,and all indicators can meet the standard of DB 21/1627-2008.The content of elements Ca,C,Cl,S,and O in the filtrate decreases after the treatment of the combination process.关键词
