Definitions
- the present invention relates to a method for purifying water and the use of this method.
- So-called standing water can also be cleaned to a large extent. In addition to pollution from the environment, these waters are particularly polluted by algae growth.
- Water can be mentioned in swimming pools and private households as examples.
- the invention relates to a method for the purification of water, a solution which contains a proportion of a microbiotic mixed culture being added to the water in a catalytically active environment.
- the method according to the invention is used for the purification of waste water and for the purification of water in public and private facilities.
- any catalytically active surface can serve as a catalytically active environment, provided, however, that the water to be cleaned and the microorganisms come into contact with it.
- a ceramic or polymer surface doped with catalyst substances can be used as the catalytically active surface.
- catalyst substances are organic and / or inorganic catalyst compounds.
- a ceramic surface is used which contains titanium dioxide (TiO 2) or indium tin oxide. Conveniently, such a ceramic surface can be a commercially available tile. It has been found that the method according to the invention can be used advantageously, for example, in the purification of swimming pool water. It is also possible to clean facade tiles using the method according to the invention. The use of such materials for wastewater treatment is known from DE 199 13 011 AI.
- the method according to the invention is also carried out using a solution which contains a proportion of a microbiotic mixed culture.
- the mixed culture contains photosynthetically active microorganisms and luminous bacteria in a microbiological solution.
- the photosynthetic microorganisms and the luminous bacteria are to be considered as a system.
- the interplay between the photosynthetically active microorganisms and the luminous bacteria leads to the photosynthetically active microorganisms being stimulated to photosynthesis by the light emitted by the luminous bacteria.
- the microorganisms carry out photosynthesis with hydrogen sulfide and water and release sulfur or oxygen. Further they can bind nitrogen and phosphate and break down organic and inorganic matter.
- Photosynthetic microorganisms which are optionally phototrophic are preferably used in the process according to the invention.
- Optional phototrophic means that the microorganisms can grow both under anaerobic conditions in the light and under aerobic conditions in the dark.
- Photosynthetic bacteria include gram-negative aerobic rod-shaped and circular bacteria as well as gram-positive circular bacteria. These can have endospores or be present without spores. These include, for example, gram-positive actinomycetes and related bacteria.
- nitrogen-binding organisms can also be mentioned.
- algae such as Anabena Nostoc in symbiosis with Azola.
- actinomycetes e.g. B. Frankia in symbiosis with alder and bacteria, such as Rhizobium in symbiosis with legumes.
- Aerobic algae, Azotobacter, methane oxidizing bacteria and sulfur bacteria can also be used. This also includes green sulfur bacteria and brown-green photosynthesis bacteria. Violet sulfur bacteria and violet sulfur bacteria cannot be mentioned here either.
- prochlorophytes, cyanobacteria, green sulfur bacteria, purple bacteria forms similar to chloroflexus and heliobacterium and as optional phototrophic microorganisms Heliobacillus-like shapes are included.
- the aforementioned optional phototrophic microorganisms can also be present as mixtures of two or more of them. In a very special embodiment, all six of the microorganisms mentioned are present as a mixture.
- the light that drives photosynthesis comes from the luminous bacteria, which are contained as a second essential component in the microbiological composition used in the method according to the invention.
- These luminous bacteria have a luminosity, i. H. they are able to emit light quanta. It is a system that works enzymatically.
- the luciferin-luciferase system can be mentioned here as an example.
- the mixed culture contains a proportion of microorganisms, especially bacteria that
- Microorganisms such as Archaea are used for the facile electron transfer of the reduction and other microorganisms such as slime molds protect the mixed culture and also serve to emit phosphorizing light. It is believed that there is a constant near the catalytic surface
- a variant of the method according to the invention consists in that when light is irradiated, such as daylight, it is also possible to work without microorganisms. It can be assumed that the catalytic environment, for example the catalytic surface, also effects water purification through photocatalytic intervention. The applicant reserves the right to make an exemption application at a later date.
- Such minor components are preferably plant extracts, enzymes, trace elements, polysaccharides, algin derivatives, other microorganisms as above.
- the secondary components can be present individually or in combination in the microbiological composition.
- the plant extracts can contain, for example, plantain, hops, etc.
- a solution is generally used as the nutrient solution for the microbiological composition used, which contributes to the fact that the constituents contained therein, in particular the microorganisms, can easily live in them. It is particularly important that the interaction of the photosynthetic bacteria and the luminous bacteria is fully effective. It has been shown that a biological nutrient solution with molasses, in particular raw sugar molasses or sugar beet molasses, is suitable as the main component.
- the photosynthetic microorganisms and the luminous bacteria are normally in one in the microbiological composition according to the invention
- the amount of the mixed culture solution used in the process according to the invention is not a particular one
- the components described above are homogenized so that a microbiotic culture is present as the first intermediate product of the method according to the invention, the proportion of which is adjusted depending on the water to be treated. If appropriate, the mixed culture is frozen for later use or lyophilized in vacuo with dehydration.
- the drying parameters are set so that the microorganisms are not damaged.
- Preliminary tests showed that a Cooling rate with more than 30 ° C per minute, preferably about 40 ° C per minute or faster is optimal in order to prevent damage to the microorganisms.
- the extracellular polymeric substances (EPS) surrounding the cells of the microorganisms are dehydrated, so that the slimy EPS layer is thickened and forms a protective layer which protects the microorganisms during the freezing process.
- EPS extracellular polymeric substances
- the water to be cleaned is stirred in order to ensure that the water to be cleaned and the microorganisms as a whole come into contact with the catalytically active environment. It is up to the user to stir continuously or discontinuously.
- the stirring can be carried out with conventional stirring devices, for example with a rod or a stirrer driven by a motor.
- the method according to the invention can be successfully used in the field of waste water purification.
- pump sumps and bodies of water can be cleaned in sewage treatment plants.
- the method according to the invention can also be safely used to produce drinking water from heavily contaminated or contaminated waters.
- the microorganisms should then be separated off using membranes in a conventional manner.
- the container is lined with a photocatalytically active layer, which consists, for example, of a ceramic containing titanium dioxide.
- a photocatalytically active layer which consists, for example, of a ceramic containing titanium dioxide.
- This ceramic is applied in the form of tiles - similar to a bathroom - and is accordingly easy to process.
- Organically contaminated waste water was poured into this lined container and a microbiotic solution according to the invention was added at the start of the experiment.
- this mixed culture contains a proportion of light-emitting microorganisms and a proportion of photosynthetically active microorganisms.
- the diagram shows that the oxygen content drops very quickly - within the first two days - and then slowly rises to a level that is higher than at the start of the experiment.
- the initial sharp drop in the oxygen concentration is due to the fact that the toxic components must first be broken down by the microorganisms. After the extensive breakdown of these toxic components, the oxygen content increases due to the decomposition of the organic components and the associated production of oxygen, until it reaches a largely constant level.
- a visual assessment of the wastewater shows that it has become much clearer compared to the initial cloudy state due to the decomposition of the organic components.
- the oxidation of the organic constituents is supported by the photocatalytic effect of the lining of the container, via which an additional oxidation of the organic compounds to H 2 O, C0, HC1, N 2 takes place in the interface area.
- the photocatalytic The effect of the lining is of course particularly good when the treated wastewater is exposed to light.
- the advantageous effect of the method according to the invention can also be demonstrated if the container is covered from daylight or another light source - the effect of the light-emitting bacteria is evidently sufficient to break down the organic constituents via the microorganisms and the photocatalytic effect of the lining enable.
- the redox potential of more than 700 mV in contaminated waters can be increased to a range of 350-400 mV using the method according to the invention. After the microorganisms have been separated off via a membrane, the remaining redox potential could then be set to> + 800 mV by adding minimal amounts of ozone and chlorine.
- the method according to the invention is also advantageously suitable for cleaning water in public and private facilities. These include, for example, swimming pools, fountains, etc.
- the waters contaminated with algae can be cleaned quickly and effectively using the method according to the invention. This means that bodies of water contaminated with pollutants that do not get into the sewage treatment plants can also be cleaned. This includes, for example, waste water from agriculture, such as horse channels, etc.
- the method according to the invention can be used to effectively purify water without the need for a special apparatus. The process is gentle on the environment and harmless to the people working with it.
