Abstract
The processes of organic compound (phenol and cation-active surfactants) destruction in water solutions, which stay under the influence of plasma treatment have been investigated in different dynamic plasma-liquid systems (PLS) with discharges in droplet micro-disperse environments (DMDE). The long-lived plasma process with separate spectral properties has been observed for pulsed discharge in DMDE. The approximate computer model is being proposed for a description of this effect. According to the introduced model this long-lived process is the aggregation of correlated discharges between charged droplets.

Summary
Methods based on plasma-chemical processes in the liquid-gas environments for water treatment and purification of highly polluted wastewater are the most promising among the others. The problem of complete cleaning of the industrial wastewaters from organic highly active and toxic substances (HATS) is important enough and simultaneously difficult to apply. This problem can not be solved completely. It is necessary to take into account that chemical reactions occurring in the liquid phase can be stimulated only by particles that penetrate from plasma into the liquid They can be active radicals created as a result of recombination processes in the plasma phase. The effectiveness of plasma-liquid systems (PLS) as applications for liquid treatment is primarily determined by the size of the interaction zone between liquid phase and plasma
