FIELD: process engineering.
SUBSTANCE: invention may be used for cleaning effluents formed in production of acetylene. For this, soot particles agglomerated to 1 mm-size are subjected to concentration of solid substances by sedimentation. Soot slime obtained in sedimentation is dehydrated at pressure. In compliance with preferable version, primary particles of soot are agglomerated to 0.001-0.05 mm-size. Immediately before sedimentation, water solution containing organic flocculant, preferably, anionic flocculant, is added to effluents. To improve wetting of floating soot particles surfactants are added before sedimentation. Besides, before filtration, water solution containing organic flocculant, preferably, anionic flocculant, is added to effluents.
EFFECT: efficient and simple process.
