含油污泥微乳化处理工艺研究

INVESTIGATION ON TECHNOLOGY OF OILY SLUDGE TREATMENT THROUGH MICROEMULSIFICATION

利用微乳化法对含油污泥进行资源化处理。通过对现场采得的SLGD含油污泥样品处理,得到该油泥的最佳微乳液组成为:SDS 0.16 g/mL,OTAC 0.04 g/mL,正丁醇0.47 g/mL,NaCl 0.034 g/mL,脱油率最高可达42.53%。最佳单次处理量为12 g(以10 mL水为基准);处理温度为30℃,最佳处理时间为30 min;在保证脱油率的前提下,微乳液可重复使用3次。

Oily sludge was treated through microemulsification.By handling the samples of SLGD containing oily sludge,the best microemulsion composition was achieved as follow： SDS 0.16 g / mL,OTAC 0.04 g / mL,butanol 0.47 g / mL,NaCl 0.034 g / mL,then the deoiling rate could reach 42.53 %.The best batch treatment capacity was 12 g（on the base of 10 mL water）,at 30 ℃ in 30 min;and the microemulsion solution could be reused for three times with the guarantee of deoiling rate.
