FIELD: detergent solutions. SUBSTANCE: invention relates to regeneration of exhausted detergent solutions containing petroleum products and suspended materials produced in the process of washing automobile and rail-way transport parts and aims at lessening technogenous environmental effect through waste waters when the same solution is repeatedly utilized. Regeneration method involves electrocoagulation with dissolving iron or aluminum anodes. Novelty consists in carrying out electrocoagulation in dynamic mode in which liquid being purified is pumped through between electrodes followed by separation of solid phase from solution, overall process being carried out in closed space wherein detergent solution is repeatedly passed through interelectrode gap until required purification degree is attained. EFFECT: improved environmental condition. 1 dwg , 1 tbl
