Definitions

  • the invention relates to a process for the degradation of organic pollutants in industrial wastewater.
  • the invention also relates to the associated system for carrying out the method.
  • Industrial wastewater is known to have a high content of organic pollutants. It is known to eliminate or at least reduce such pollutants by electrochemical oxidation.
  • the COD value can be lowered.
  • This process can be carried out in particular electrochemically, but also by adding chemicals or by introducing ozone gas.
  • the object is achieved according to the invention by the measures of patent claim 1.
  • An associated device / system is specified in claim 11. Further developments of the method and the associated system are the subject of the dependent claims.
  • a method is specified, which increases the energy efficiency of the electrochemical COD degradation, especially by a prior concentration of the liquid stream to be treated.
  • the different methodological approaches known per se can be used.
  • the concentration can be effected by membrane processes - such as ultrafiltration (UF), such as nanofiltration (NF), such as reverse osmosis (RO), and / or electrodialysis (ED).
  • UF ultrafiltration
  • NF nanofiltration
  • RO reverse osmosis
  • ED electrodialysis
  • This can be used to define procedures that significantly increase the energy efficiency of an electrochemical cell, especially for COD removal.
  • the conductivity of the medium increases in a known manner, as a result of which the cell voltage is reduced.
  • the efficiency of the process can be further increased.
  • there is the possibility of optimizing the cell structure For example, larger electrode distances simplify the mixing and it can thus be easier to clean the system. Even so, the effectiveness of the system according to the invention is increased.

  • the contaminated liquid is usually an industrial water, in particular contaminated with organic substances.
  • the sum of the impurities is defined by the so-called COD degradation.
  • COD degradation In practice, there are clear legal requirements for the value of a permissible COD contamination.
  • the COD value can be reduced electrochemically in practice, for example. This is usually done by concentrating the organically contaminated water.
  • the concentration of the organically contaminated water can be realized, for example, by membrane processes (UF, NF, RO, ED).
  • UF, NF, RO, ED membrane processes
  • the so-called concentration after the concentration must be treated electrochemically, wherein a so-called permeate is obtained as a by-product.

Abstract

L'invention concerne en particulier des eaux usées industrielles qui contiennent souvent des constituants organiques sous forme de substances nocives. De telles substances nocives organiques peuvent être éliminées comme on sait par l'application de procédés électrochimiques, pour lesquels on utilise de l'oxygène. Pour la pratique, on définit une valeur CSB (besoin en oxygène chimique), qui doit être respectée par l'industrie. Selon l'invention, les substances nocives organiques sont d'abord concentrées (1, 2) et le liquide avec les substances nocives concentrées est soumis ensuite à une électrolyse (3).
