Definitions
- Wastewater treatment method and apparatus for carrying out this method are
- the invention relates to a method for wastewater treatment and to a device for carrying out this method. Both find
- Procedures and equipment can also be used for raw material recovery
- phosphates and ammonium compounds should be selectively removed from the wastewater.
- AOP Advanced Oxidation Process
- Oxidizing agents such as ozone or hydrogen peroxide, for the decomposition of organic and inorganic substances in the wastewater by oxidation (Wikipedia, keyword “Advanced Oxidation Process”) .
- This AOP process sometimes does not ensure their complete purification in the treatment of heavily polluted waste water, so that a direct feed into It is also not possible because of the poor efficiency of high-voltage ozone generation.
- Electrolytic processes have proven to be more favorable in terms of energy, with inorganic (ion-forming)
- Cleaning process can be supplied. Another aspect of this task is the recovery of raw materials from agricultural and municipal wastewater or those from biogas plants.
- the inventive method and the inventive device for wastewater treatment are used in particular for the removal of organic pollutants, suspension separation, removal of biological contamination and heavy and non-ferrous metals in wastewater, according to the invention a module for performing a fort as an AEOP (advanced electrochemical oxidation process) designated method is used.
- AEOP advanced electrochemical oxidation process
- an anode cage made of the materials platinum, titanium, niobium, palladium, ruthenium or placed titanium is used.
- Anodenhimfig is dimensionally stable and preferably made of expanded metal. We then put the sacrificial metal into this anode cage. Therefore, it is called a sacrificial anode. Since this anode cage can be filled mixed with metals, this also fulfills the function of a mixing electrode that does not exist in this form. It is also possible to add metals such as magnesium and calcium to this mixing electrode. This leads to the elimination of ammonium and phosphate in the wastewater. The removal takes place in this case as Magnesium ammonium phosphate (struvite). When using iridium oxide or tantalum oxide or mixtures thereof, a disinfection of water at a salinity of> 0.2% by mass is carried out by nascent chorus.
- iron, aluminum, carbon, magnesium and calcium is used as sacrificial material according to the invention. These materials can also be mixed in the anode cage.
- the above method can also be combined with membrane technologies. This has the advantage that biofouling can be avoided.
- the waste water treatment is carried out for removal of particulate pollutants (for example suspension separation), organic ingredients, heavy metals or toxic metals in general and of pharmaceuticals.
- This purification method is preferably used in the form of oxidative precipitation using iron, aluminum; Calcium or magnesium applied. It can be used for many applications, such as oils and fats, small and finest dirt particles, heavy and toxic metals. As a result, the heavy metal content can be reduced up to the detection limit and the organic load by up to 75%.
- the combination of the AEOP process with at least one other known process ensures excellent quality of the purified wastewater.
- the process is optimally conducted at current densities between 40 and 120 mA / cm 2 .
- the voltage is 2 to 12 V and pH is preferably in the range between 5 and 9, that is to say comprises a range from acidic to neutral to basic. Since the present electrolytic conductivity depends on the ion concentration, the Current density on the voltage adjustable, with a lower limit of the electrode spacing and thus the required electrical power is given by the fact that the formed ions both signs again recombine at too small a distance. This
- Minimum distance is in the case of organically polluted municipal sewage relatively low conductivity about 1 to 3 cm, but must be made mostly larger for reasons of flow resistance and to avoid blockages.
- membrane techniques mentioned in claim 5 serve to separate the insoluble precipitates of pollutants due to their inclusion in or chemical bonding to the anodically dissolved sacrificial materials. It can also be other separation methods than those listed
- dangerous ingredients such as heavy metal compounds
- the task according to the task can be done as a fertilizer.
- Fig. 4 a schematic representation of a tubular reactor in
- Fig. 5 a schematic representation of a tubular reactor in
- FIG. 1 shows an AEOP precipitation reactor 1 followed by a filter unit 2, which is a
- Chamber filter press or can act on an automatic filter.
- FIG. 2 shows the schematic structure of the AEOP reactor 1 according to the invention. It generally has the shape of a tube 3 closed at both ends by a closure cover 7, which accommodates the anode cage 4, which is only indicated here but shown in detail in FIG. Any other geometric shape may be chosen for the AEOP reactor.
- a closure cover 7 which accommodates the anode cage 4, which is only indicated here but shown in detail in FIG. Any other geometric shape may be chosen for the AEOP reactor.
- the wastewater to be purified is introduced and the effluent treated at an outflow 6 is withdrawn.
- the tube 3 is in its entirety with the exception of the end-side closure lid 7 on cathode potential, the
- Cathode terminal 8 is connected. Therefore, it is to be ensured by not shown insulating spacers that no metalic contact between the tube 3 and the anode cage 4 occurs inside the tube 3, so that the intervening wastewater is subjected to the electrolytic treatment essential to the invention.
- Fig. 3 shows the dimensionally stable anode cage 4 in side view. It can also any, but to the shape of the reactor vessel
- Expanded metal consists, as described above, of platinum, titanium, Niobium, palladium, ruthenium or placed titanium. Inside the anode cage 4 is not specifically highlighted here, sacrificial material described in detail above.
- anode cage 4 can be seen as it is electrically insulating
- Spacers 9 centered is held therein. In the longitudinal direction it extends, as indicated in Fig. 5, over the entire length of
- Tube reactor 9 except for the cut right end of the same.
- the wall 11 of the tube reactor 9 is either itself at cathode potential or it is designed to be electrically insulating and internally coated with the cathode material.
- the wastewater to be treated flows, of course, as intended for anodic
- Pipe reactor 10 may now be at an upper outlet 13 according to purified wastewater and at a lower outlet 14 enriched precipitates are each taken to further treatment.
- the outflow of these enriched in the lower part of the tubular reactor 10 precipitations can be promoted by a knocking or vibration device 15 mounted there externally.

Abstract
L'invention concerne un procédé de traitement d'eaux usées et un dispositif associé. L'invention vise à créer un procédé et un dispositif qui garantit de façon fiable, l'élimination de polluants d'eaux usées avec un bon rendement énergétique, par lequel l'eau purifiée peut être introduite en tant qu'inducteur direct ou peut être acheminé dans des cas spéciaux, à un autre processus d'épuration. L'invention concerne également la récupération de matières premières des eaux usées de l'agriculture et des eaux usées communales ou provenant d'installations de biogaz. A cet effet, l'invention propose un procédé qui comprend un traitement électrolytique des eaux usées en utilisant une anode qui comprend, aussi bien des matériaux résistant à l'électrolyse que des matériaux sacrificiels se dissolvant lors de l'électrolyse qui sont soumis tous deux en même temps aux eaux usées. Un dispositif de réalisation du procédé présente en tant que partie résistant à l'électrolyse de l'anode, une cage d'anode de forme stable (4) en platine, titane, niobium, palladium, ruthénium ou titane plaqué qui est doté d'aluminium, de fer, de magnésium, de calcium ou de mélanges de ces métaux en tant que matériau sacrificiel. L'invention peut être utilisée pour le traitement des eaux usées.
