Definitions
- the present invention relates to a wastewater treatment process. STATE OF THE TECHNIQUE
- the biological filter comprises a container container filled with a bed of inert material, generally plastic, of variable geometry through which the stream of water to be treated is passed, which completely floods the container that acts as a biological reactor where it develops a biofiim of microorganisms, responsible for biological treatment, that carry out the purification of wastewater by oxidizing the organic matter present in the water.
- An air stream is usually provided to the filter in order to provide the oxygen necessary to support the biological purification of water.
- the role of oxygen is to consume the electrons generated in the biological oxidation of the organic matter present in the waters.
- the air supply represents an additional cost in the treatment of water, while generating a large amount of bomase or sludge due to the high cellular performance of aerobic microbial metabolisms. If the biofilter is operated on Anaerobic conditions, this is without additional oxygen supply, it is possible to reduce the production of biomass but the purification rate is slowed in the absence of electron acceptors that consume the electrons generated in the oxidation of organic matter.
- the present invention seeks to solve one or more of the drawbacks set forth above by a wastewater treatment method as claimed in the claims.
- An object of one embodiment is to provide a wastewater treatment device comprising a container container refillable with a biocompatible bed of electrically conductive inert material, namely the final acceptor of negative electrical charges or electrons produced in redox reactions.
- This conductive biocompatible bed favors the realization of biological processes for the elimination of oxidizable matter, namely organic matter or any biodegradable waste such as urban wastewater, industrial effluents, plant residues etc.
- Another aspect of the embodiment is to provide a wastewater treatment device with greater wastewater purification capacity through oxidation reactions, therefore, it has improved performance, space needs are reduced, nitrification improves by oxidation of ammonium with a view to the reuse of effluent waters so that they comply with the regulations in force.
- Another aspect of the embodiment is to provide a biocompatible bed of electrically conductive inert material that is integrated in the electron transport chain where the final acceptor thereof is generally an inorganic molecule.
- the biocompatible bed is granulated in particles with a variable grain size, or uniform, to provide an outer surface conductor that is part of the electron transport chain.
- the conductive biocompatible bed favors oxidation reactions by increasing the ability of microorganisms to transfer electrons, generated during oxidation processes, to the surface of said bed and from the bed surface to final acceptors of the electrons, generally, an inorganic molecule.
- Yet another aspect of the embodiment is to provide a biocompatible bed of electrically conductive inert material comprising a non-conductive electron core coated by an electron conducting material.
- the conductive biocompatible bed is graffiti, coal coke, or the like.
- Yet another aspect of the embodiment is to provide a simple process for the treatment of streams of contaminated water with dissolved nitrogen compounds by means of the bacterial action that transforms these compounds into gaseous nitrogen.
- the treatment device comprises a container filled with a conductive biocompatible bed of inert material and, in addition, electron transporter, which purifies wastewater through an anaerobic biological process and removes contaminating substances, such as nitrogen compounds.
- Yet another aspect of the embodiment is to provide a treatment device for the treatment of wastewater at atmospheric pressure and ambient temperature, which minimizes the production of sludge, or biomass, without the artificial contribution of oxygen to the treatment device.
- Yet another aspect of the embodiment is to apply this concept to the construction of artificial wetlands that favor oxidation or purification of matter transported by wastewater minimizing sludge or biomass production, and thus minimizing the phenomena of clogging the filter substrate.
- Figure 1 shows how the wastewater is purified by crossing a conductive biocompatible bed
- Figure 2 shows a detail of the microbial purification process; that is, oxidation of organic matter and ammonium coupled to the reduction of acceptors through the conductive biocompatible bed,
- a wastewater treatment device comprising a container container filled entirely or partially with a biocompatible bed of electrically conductive inert material, an inlet that supplies a flow of water to be purified that it totally or partially floods the container container, so that the biocompatible bed acts as a biological reactor; and an outlet for purified water.
- the biocompatible bed is a conductive hydrophilic material such as graphite, coke, etc., available in the form of particles or grains, the particle size may be variable or uniform.
- the biocompatible bed constitutes a substrate where a biofilm of microorganisms responsible for anaerobic wastewater treatment is developed.
- the biocompatible bed is adapted to favor the growth of the biofilm of microorganisms on its outer conductive surface. This surface is part of the transport chain of ions generated in the processes of microbial oxidation of the matter transported by the residual water that floods the biocompatible bed.
- the biocompatible bed is adapted to transfer the electrons generated during oxidation reactions to final acceptors, generally an inorganic molecule such as SO 4 " “ , NQ 2 ⁇ , NO 3 " , C0 2 , etc.
- biocompatible bed is saturated with water results in oxygen being consumed on the surface of the bed, so it cannot participate in oxidation processes within the biological treatment or reactor device. Consequently, the bed is anaerobic.
- the biocompatible particles within the biological reactor provide a conductive zone that favors the oxidation processes of the matter transported by the wastewater, first favoring the transfer of the electrons released during the oxidation process to the biocompatible bed itself and, subsequently, to inorganic molecules.
- Both the biological reactor and the size of the biocompatible bed particles are designed in terms of their size, and the speed of the movement of water through the same reactor, so that the residence time of the water around the Biocompatible particles are sufficient to favor oxidation reactions and, therefore, so that the transfer of electrons is substantially completed to inorganic molecules, ensuring that all residual water is treated,
- an important parameter to determine the wastewater treatment capacity is the numerical value of the outer conductive surface provided by the granulated biodegradable bed, that is, the greater the conductive surface, the greater the electron transfer capacity has the granulated biocompatible bed and, therefore, the treatment device, or biological reactor, or artificial wetland, has a greater wastewater treatment capacity.
