Method of wastewater treatment from emulsified petroleum products

摘要

The authors developed the composition of integrated adsorbent for the disposal of wastewater containing cutting fluids and consisting of decaying steel slag and iron ore concentrate at a weight ratio of 1:1.5.It was identified that the maximum degree of cleaning from emulsified petroleum products(EOP)is observed at the size of adsorbent particles(d)in the range of 80>d>50 um.The values of the process hydrogen ion exponent pH ≤ 3 while the ratio between solid and liquid phases at the separation of water and emulsified petroleum products is equal to 0.6-0.7.The authors managed to set the parameters of the magnetic processing of a suspension consisting of complex adsorbent and water&oil emulsions with subsequent separation of the aqueous and oil phases.At this,the magnetic field intensity was equal to 180 kA/m and the magnetic field processing time - 120 seconds.
