LEVEL OF CONVECTIONAL TECHNOLOGY Up to now the disposal of liquid waste from fish slaughtering is achieved with biological treatent. The efficlency of such a process depend on the sudden increase or decrease of the organic load in the waste, it is vulnerable to weather conditions, the result of the process is not steady and rarely with in the law, the disinfection that is completed in the last stage do not have the power to eliminate all the pathogen and creates during it's operation mud which is a huge environmental problem. The running cost of such a process is high.

ADVANTAGES OF THE INVENTION The method, due to the production of powerful oxidants during electrolysis, such as 02, CI2, CI02, 03, 02, H202, [OH], [CLOH] [O] successfully oxidize all organics in the waste mass, no mud is created, it does not depend on any outer effects such as climate conditions and the running cost is noticeably lower than a biological treatment.

DESCRIPTION The liquid waste from fish slaughtering activity is created from the slaughtering department, the blood drainage department and from the disinfection procedure of the areas.

The invention refers to the wet oxidation-sterilization of the wastes from fish slaughtering by electrolysis where the conciseness of the liquid waste and sodium chloride is between 0, 5% and 5% in weight/weight, the voltage of direct electric current is between 6V and 48V and the intensity of the direct electric current is between 50Amp and 500Amp. The temperature during electrolysis is between 14°C and 60°C and the pH value between 2 and 9,5 points. For better results of oxidation- sterilization of the wastes, before they enter the electrolytic cell or the tank where the cell is, they passed from a fine grid, type screen or cylinder, spaced between 1mm to 0, Olmm. The neutralization of the

residual oxidants is accessed by sodium sulfite, or sulfur dioxide assisted by redox meter.

EXAMPLE 1 (drawing 1) 50 liters of waste from fish slaughtering conciseness of 2% in sodium chloride are guided to screen (a) type cylinder with spacers 0,29mm to subtract any solid. The total volume is entering to the tank (b) 1001it capacity where a submersible pump (c) of re circulation 15m3/h driven this to the electrolytic cell (d). Noble and strategic metals make the anode of the cell and stainless steel 316L the cathode. The cell (d), is powered by a DC transformer (e), with controlled voltage 0, 5V to 48V and controlled intensity 0, 5Amp to 500Amp. The waste water entering the cell (d) and re-circulated by the pump (c) is electrolyzed with a voltage 16V and an intensity of 100Amps for 60 minutes. The system has a thermal exchanging device (f), which keeps temperature below 60°C and especially to 30°C. The pH is maintained between 2 and 9,5 points and specially to 8, 5 points by the support of a pH meter (g), which upon request adds oxide or base to the process from the tanks (h) or (i). At the end of electrolysis, assisted by redox meter (j), the wastes are neutralized from the residual oxidants by addition of sulfur dioxide from tank (k).

EXAMPLE2 (drawing2) 50 liters of waste from fish slaughtering conciseness of 2% in sodium chloride are guided to screen (a) type cylinder with spacers 0,29mm to subtract any solid passing towards tank (b) of 1001it capacity. In tank (b) there is an electrolytic cell (c) witch noble and strategic metals make the anode of the cell and stainless steel 316L the cathode. The cell (c) is powered by a DC transformer (d), with controlled voltage 0,5V to 48V and controlled intensity 0, 5Amp to 500Amp. The liquid waste in tank (b) is electrolyzed for 60 minutes with a voltage 16V and an intensity of lOOAmps. Through pH meter (f), I fix the value between 2 and 9,5 and especially to 4 points by addition of hydrochloric acid from tank (g). At the end of electrolysis, assisted by redox meter (j), the wastes are neutralized from the residual oxidants by addition of sulfur dioxide from tank (k)
