Pollutant Leaching Behaviors of the Solidified Oily Sludge

Article Preview

Abstract:

Solidification is one effective method to treat the oil contained sea drill cuttings. To understand the pollutant leaching behaviors of the solidified oily sludge from Bohai drill cuttings, a series of experiments of solidification, curing, soak and analysis were carried out. The pollutant indexes of oil content and COD in the soak solution were tested. The influence of the composition of solidified agents, curing time and soak method of static soak or dynamic soak are discussed. The new concepts of C-O diagram and C/O value were proposed to present the characteristics and behaviors of pollutant leaching from the solidified oily sludge.
