Definitions
- the invention relates to a process for the degradation of biological and / or organic substances in the liquid phase, in particular for the disinfection of liquids, by bringing an all-metal catalyst into active connection with an oxidizing agent.
- biocides are added, which may contain phosphorus, bromine, chlorine or the like, among other things. These raw materials are considered toxic.
- targeted water poisoning is initially accepted, the residual water remaining after the wastewater purification, or its thickened solid components, having a high potential for pollution.
- DE-C 195 03 865 is a catalyst containing manganese, nickel and copper for the oxidation of water constituents in the presence of hydrogen peroxide and oxygen, which is obtained by thermal treatment of one of 10 to 30 wt .-% copper and 5 to 15 wt .-% % Nickel and 60 to 80% by weight of manganese existing alloy at temperatures of 400 to 1000 ° C in an oxygen-containing atmosphere for a time of 0.25 to 5 hours.
- the catalyst can additionally contain at least one of the elements iron, chromium, silicon, titanium, aluminum, molybdenum, phosphorus or nitrogen in an amount up to a total of 5% by weight.
- CH-A 605 421 is a method for disinfecting bathing, drinking and industrial water with hydrogen peroxide by adding hydrogen peroxide to the water and activating it or catalyzing its decomposition.
- the catalysis is to be carried out by means of a current cell, the electrodes of which are made of copper, iron, graphite, nickel, platinum or silver. A surface treatment of the metal electrodes is not provided. It is also proposed that the addition of at least one substance which contains copper, palladium, iron, nickel, cobalt, lead, cadmium or silver be catalyzed, as a result of which the water to be treated is contaminated with heavy metal ions.
- DE-C 196 10 345 describes a catalyst for the oxidation of waste water contaminants by means of peracids and / or hydrogen.
- An alloy consisting of 10 - 60 mass% Co, 5 - 50 mass% Ni, 5 - 20 mass% W and 5 - 25 mass% Cr is used for Temperatures in the range of 250 ° C to 1250 ° C for a time 0.5 to 3 hours in an oxygen-containing atmosphere thermally treated.
- DE-A 196 30 043 discloses a catalyst containing manganese for the oxidation of impurities in acidic waste water.
- An alloy consisting of (in mass%) 10 - 40% Mn, 10 - 25% Cr and 50 - 70% Fe as the rest is in the temperature range of 300 - 1200 ° C for 0.3 to 3 hours in an oxygen-containing atmosphere thermally treated.
- the catalyst obtained in this way is brought into contact with the waste water containing hydrogen peroxide to be treated for 1 to 60 minutes in that the waste water passes over or through it several times.
- the object of the invention is to provide a method for the degradation of biological and / or organic substances, in particular for the disinfection of liquids, which manages with at least equally good cleaning of the substances, in particular the liquids, without the addition of environmentally harmful biocides.
- heavy metal ions should also be prevented from penetrating into the aqueous phase.
- the full metal catalyst is produced from the following components:
- At least one alloy element of a group I at least one alloy element of a group II, at least one alloy element of a group IM,
- group I includes the alloying elements Ni, Mg, Ba, Ca, Sr, which form divalent oxides below the Tammant temperature in an oxygen-containing atmosphere
- group II includes the alloying elements Cr, B, Al, Ga, indium, which only form trivalent oxides below the Tammant temperature in an oxygen-containing atmosphere
- group III includes the alloying elements Fe, Cu, Mn, Mo, W, V, which in Dependence on temperature and gas atmosphere, especially that
- Oxygen partial pressure form oxides in different oxidation levels, that the full metal catalyst is annealed, and that the full metal catalyst thus obtained is in operative connection with the
- Oxidizing agent and the substance is brought.
- the subject of the invention deals with solid reactions and their interfaces. Reactions in which one or more solid phases are involved have peculiarities due to the relatively rigid fixation of their particles, in the periodic as well as the aperiodic lattice, compared to reaction between gases or liquids that are miscible with one another. In contrast to liquids and gases, solids are rarely in the normal state of thermodynamic equilibrium. Understanding solid reactions requires the elucidation of a whole Sequence of steps, whereby physical processes of substance energy and impulse transport are just as important as the actual chemical reactions. The mass transport takes place as a change of location of individual lattice building blocks either through the lattice or volume diffusion, the grain boundary diffusion and the surface diffusion or through chemical transport via the gas phase.
- the reaction rate is determined by the respective diffusion mechanism and the associated activation energy of the place change process. It is generally only worth mentioning at relatively high temperatures, so that the solid reactions, at least those which take part in the exclusively solid phases, have their domain in the case of thermally stable organic compounds. However, this does not mean that changes of location are not detectable even at relatively low temperatures.
- Tamman defined the temperature of the noticeably beginning change of location, with the Tammant temperatures for metals around one third, for oxides around two thirds and for organic compounds below three quarters of the melting temperature of these substances.
- the degradation of biological and / or organic substances in the liquid phase in particular the disinfection of liquids, can take place without the use of biocides, which in addition to an at least equally good cleaning of the substances, in particular the liquids to be disinfected, thus occurs the use of any biocides can be dispensed with.
- biocides which in addition to an at least equally good cleaning of the substances, in particular the liquids to be disinfected, thus occurs the use of any biocides can be dispensed with.
- CH-A 605 421 also prevents heavy metal ions from penetrating into the aqueous phase.
- the full metal catalyst consists of alloys that are thermodynamically capable of releasing electrons in aqueous systems. This creates a positively charged surface.
- the decisive feature of the full metal catalyst according to the invention is that, despite the positively charged surface, no metal cations leave the metallic composite. This is achieved by forming a special surface structure that only allows electrons to pass through.
- the full metal catalyst according to the invention reacts with hydrogen peroxide.
- a hydroxide anion and a hydroxyl radical are formed from one molecule of hydrogen peroxide by taking up an electron.
- the full metal catalyst is charged positively, with negatively charged germs now accumulating on the catalyst surface.
- Germs interact with the positively charged catalyst surface.
- the germ layers are disassembled on the catalyst surface with the help of hydrogen peroxide. This releases a large amount of surface-active substances.
- the germ dies and disappears from the catalyst surface within a short time.
- the full metal catalyst according to the invention recovers the previously released electrons and the cycle can start again.
- the surface-active substances are now able to replace the biofilms in the water cycle.
- the metabolic processes in the biofilm are considerably disturbed, whereby the detached components die off or are removed from the circuit by filter stages or blowdown.
- Group I forming the full metal catalyst is based on the following alloying elements: nickel, magnesium, barium, calcium, strontium.
- the group II forming the full metal catalyst is based on the following alloying element: chromium, boron, aluminum, galium, indium.
- Group III is essentially based on the following alloying elements: iron, copper, manganese, molybdenum, tungsten and vanadium.
- the alloying elements on which the latter group III is based can form oxides of different valences depending on the temperature and gas atmosphere, in particular the oxygen partial pressure.
- iron can be bivalent or trivalent
- manganese can be bivalent, trivalent or tetravalent
- molybdenum can be trivalent, tetravalent, pentavalent or hexavalent.
- the full metal catalyst which is present in tempered form, can be doped on the surface with alkali metals.
- the full metal catalyst is in the form of wire, sheet metal, foil or foam, in the form of knitted fabrics, woven fabrics, honeycomb moldings, structured packings or the like.
- the number of bacteria is determined before the start and after the 3 h.
- the disinfection rate is:
- KZ ° KZi number of bacteria after 30 min
- the catalysts of the invention consistently showed activities in the methylene blue test of over 90% and in the disinfection test a disinfection rate of at least 3 powers of ten (99.9%).
- the correspondingly selected comparison samples also showed a certain effect in both tests, but both samples showed a tendency to corrosion that was too high for practical use. But while with Copper had the intended tests carried out, the corrosion stresses in the normal steel were so pronounced after only a few hours that the tests could only be evaluated to a limited extent.
