Definitions

  • the invention refers to the electrochernical method for wet oxidation- sterilization of the liquid wastes from fish slaughtering.
  • the method due to the production of powerful oxidants during electrolysis, such as 0 2 , CI 2 , CI0 2 , 0 3 , 0 2 , H 2 0 2 , [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 riinning cost is noticeably lower than a biological treatment.
  • the liquid waste from fish slaughtering activity is created from the slaughtering department, the blood drainage department and from the c sMection procedure of the areas.
  • the invention refers to the wet oxidation - sterihzation 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 50An ⁇ p a d 500Amp.
  • the temperature during electrolysis is between 14°C and 60°C and the pH value between 2 and 9,5 points.
  • the waste water entering the cell (d) and re-circulated by the pump (c) is electrolyzed with a voltage 16 V and an intensity of lOOAmps 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).
  • redox meter (j) the wastes are neutralized from the residual oxidants by addition of sulfur dioxide from tank (k).

Abstract

L'invention a trait à un procédé électrochimique permettant l'oxydation-stérilisation humide de déchets liquides provenant de l'abattage des poissons, au cours duquel l'écoulement des eaux usées est commandé par des grilles, une tension contrôlée et une intensité contrôlée de courant continu électrique, la teneur en chlorure de sodium dans les eaux usées, la température des déchets liquides pendant l'électrolyse, la valeur du pH pendant l'électrolyse et l'élimination d'agents oxydants résiduels avec du sulfite de sodium ou du dioxyde de sulfure. Grâce à ce procédé, il est possible d'assurer l'élimination totale de tous les pathogènes et, par la même, réduire la teneur en BOD5, COD, couleur et TSS dans les limites prévues par la loi.
