Description
Die Erfindung betrifft ein Verfahren zur Entfernung von Schadstoffen aus Wässern durch Adsorption der Schadstoffe an Sorptionsmaterialien aus nachwachsenden Rohstoffen, wobei es sich bei den Schadstoffen um aerob biologisch schwer oder nicht abbaubare organische Verbindungen handelt. Das mit Schadstoffen beladene Sorptionsmaterial wird in einer Biogasanlage anaerob vergärt und dient somit als Substrat oder Co-Substrat zur Biogasgewinnung. Das Verfahren ist insbesondere für schadstoffbelastete Wässer mit relativ geringen Schadstoffkonzentrationen geeignet, insbesondere für Wässer mit geringen Konzentrationen an Arzneimittelrückständen, Reinigungsmittelrückständen, Rückständen von Pflanzenschutzmitteln, Lösungsmitteln und Industriechemikalien.The invention relates to a method for removing pollutants from water by adsorbing the pollutants on sorbent materials from renewable raw materials, the pollutants being organic compounds which are difficult to aerobically biodegradable or which are not biodegradable. The sorption material loaded with pollutants is fermented anaerobically in a biogas plant and thus serves as a substrate or co-substrate for biogas production. The method is particularly suitable for polluted water with relatively low concentrations of pollutants, especially for water with low concentrations of pharmaceutical residues, cleaning agent residues, residues of pesticides, solvents and industrial chemicals.
Es ist bekannt, dass organische Spurenstoffe aus Wässern mittels Filtrations-, Ab- und Adsorptionsverfahren sowie Oxidationsverfahren, beispielsweise Membranfiltration, Aktivkohlefiltration und Ozonisierung, eliminiert werden können. Als Sorptionsmittel in adsorptiven Wasseraufbereitungsanlagen werden Aktivkohlen unterschiedlicher Art, Adsorberpolymere und oxidische Adsorbentien genannt. Aktivkohlen werden in Form von Pulverkohle, Kornkohle und permeablen, synthetischen Kollektoren angewendet. Als Adsorberpolymere sind Ionenaustauscher wie Lewatit® EP 63 bekannt. Als oxidische Adsorbentien sind Kieselgel, Alumosilikate, Aktivtonerden und granuliertes Eisenhydroxid zu nennen. Eisenhydroxid dient z. B. zur Adsorption von Arsen, Schwermetallen und Phosphaten. Aktivkohle eignet sich z. B. für die Entfernung von Lösungsmitteln, Pflanzenschutzmitteln, Geschmacksstoffen und Färbungen.It is known that organic trace substances can be eliminated from water by means of filtration, absorption and adsorption processes and oxidation processes, for example membrane filtration, activated carbon filtration and ozonization. Different types of activated carbon, adsorber polymers and oxidic adsorbents are mentioned as sorbents in adsorptive water treatment plants. Activated charcoals are used in the form of powder charcoal, grain charcoal and permeable, synthetic collectors. Ion exchangers such as Lewatit® EP 63 are known as adsorber polymers. Silica gel, aluminosilicates, active alumina and granulated iron hydroxide are to be mentioned as oxidic adsorbents. Iron hydroxide is used e.g. B. for the adsorption of arsenic, heavy metals and phosphates. Activated carbon is suitable e.g. B. for the removal of solvents, pesticides, flavors and colorings.
Es ist auch bekannt, dass Biosorbentien Schwermetalle aus Wässern eliminieren. Standardgemäß werden Biosorptionsverfahren für große Wasserströme mit relativ geringen Schadstoffkonzentrationen eingesetzt.It is also known that biosorbents eliminate heavy metals from water. Biosorption processes are used as standard for large water flows with relatively low concentrations of pollutants.
Zum Beispiel beschreibt
Mit der Aufbereitung von Sorptionsmaterialien in Ziegeleien beschäftigt sich
Die Nachteile der genannten, herkömmlich angewendeten Sorptionsmaterialien zur Adsorption von Schadstoffen aus Wässern sind deren begrenzte Verfügbarkeit und der Aufwand ihrer Entsorgung bzw. Regenerierung. Dazu kommt, dass die herkömmlichen Wasseraufbereitungsverfahren zur Entfernung dieser Schadstoffe aus wässrigen Strömen für geringe Konzentrationen an Schadstoffen nicht geeignet sind.The disadvantages of the aforementioned, conventionally used sorption materials for adsorbing pollutants from water are their limited availability and the expense of their disposal or regeneration. In addition, conventional water treatment methods for removing these pollutants from aqueous streams are not suitable for low concentrations of pollutants.
Aufgabe der vorliegenden Erfindung war es deshalb, ein Verfahren zur Reinigung von schadstoffbelasteten Wässern mittels Adsorption bereitzustellen, das die Nachteile des Standes der Technik überwindet.The object of the present invention was therefore to provide a method for cleaning polluted water by means of adsorption which overcomes the disadvantages of the prior art.
Erfindungsgemäß wird ein Verfahren zur Entfernung von Schadstoffen aus Wässern mit den Merkmalen gemäß Anspruch 1 bereitgestellt, wobei es sich bei den Schadstoffen um biologisch schwer oder nicht abbaubare organische Verbindungen handelt. Das Verfahren ist dadurch gekennzeichnet ist, dass die schadstoffbelasteten Wässer einer Sorptionsstufe zur Adsorption der Schadstoffe zugeführt werden, wobei die Sorptionsstufe mindestens einen Hauptfilter mit Biomassen aus nachwachsenden Rohstoffen als Sorptionsmaterial umfasst, das mit Schadstoffen angereicherte Sorptionsmaterial als Substrat in einer Biogasanlage anaerob zu Biogas vergoren wird und der bei der Vergärung entstehende Gärrest nachbehandelt wird.According to the invention, a method for removing pollutants from water is provided with the features according to
Bei den Wässern handelt es sich insbesondere um schadstoffbelastete Oberflächen- oder Grundwässer, um schadstoffbelastete Wässer aus Krankenhäusern, Pflege- und Altersheimen, der kosmetischen und pharmazeutischen Industrie und der Landwirtschaft. Insbesondere können mit dem erfindungsgemäßen Verfahren große Wasserströme mit relativ geringen Schadstoffkonzentrationen aufbereitet werden. Die Schadstoffkonzentrationen der Wässer liegen häufig bei kleiner 1mg/l.The waters are in particular polluted surface or groundwater, polluted waters from hospitals, nursing and old people's homes, the cosmetic and pharmaceutical industry and agriculture. In particular, large water flows with relatively low concentrations of pollutants can be treated with the method according to the invention. The pollutant concentrations in the water are often less than 1 mg / l.
Bei den biologisch schwer oder nicht abbaubaren organischen Verbindungen handelt es sich im Sinne der Erfindung insbesondere um Arzneimittelrückstände,
Reinigungsmittelrückstände, Rückstände von Pflanzenschutzmitteln, Lösungsmittel und Industriechemikalien. Als Arzneimittelrückstände sind beispielhaft Carbamazepin, Natrium-Diclofenac oder Sulfamethoxazol zu nennen.The organic compounds, which are difficult to biodegrade or not biodegradable, are in particular pharmaceutical residues in the context of the invention,
Detergent residues, residues of pesticides, solvents and industrial chemicals. Carbamazepine, sodium diclofenac or sulfamethoxazole are examples of drug residues.
Als Sorptionsmaterialien werden Biomassen aus nachwachsenden Rohstoffen eingesetzt, die anaerob zu Biogas vergoren werden. Insbesondere kommen als Biomassen aus nachwachsenden Rohstoffen zellulosehaltiges oder stärkehaltiges Pflanzenmaterial oder Gemische dieser Materialien in Frage. Besonders bevorzugt kann als Biomasse Algenbiomasse, z. B. Chlorellapulver, oder Hefen-Biomasse eingesetzt werden oder als stärkehaltiges Pflanzenmaterial Getreide, wie z. B. Weizen oder Mais, verwendet werden.Biomass from renewable raw materials, which are fermented anaerobically to form biogas, are used as sorption materials. In particular, cellulosic or starchy plant material or mixtures of these materials come into consideration as biomasses from renewable raw materials. Algae biomass, e.g. B. Chlorella powder, or yeast biomass can be used or as starchy plant material cereals, such. B. wheat or corn can be used.
Es ist bevorzugt, das Sorptionsmaterial oder das Gemisch dieser Materialien im Hauptfilter schichtweise anzuordnen.It is preferred to arrange the sorbent material or the mixture of these materials in layers in the main filter.
In einer bevorzugten Ausführungsform des Verfahrens werden in der Sorptionsstufe zwei parallel geschaltete Hauptfilter verwendet, um jeweils nach Erreichen der Schadstoff-Beladungskapazität des Sorptionsmaterials des einen Hauptfilters die Wässer über den parallelen Hauptfilter mit frischem Sorptionsmaterial leiten zu können, um eine kontinuierliche Verfahrensführung zu gewährleisten.In a preferred embodiment of the method, two main filters connected in parallel are used in the sorption stage in order to be able to pass the water through the parallel main filter with fresh sorbent material after reaching the pollutant loading capacity of the sorbent material of the one main filter in order to ensure a continuous process.
In einer anderen Ausführungsform des Verfahrens umfasst die Sorptionsstufe einen Hauptfilter, dem wahlweise ein Vorfilter und/oder ein Nachfilter zugeordnet ist. Vorzugsweise wird ein Nachfilter benutzt. Bei Wässern mit nahezu gleichmäßigem Gesamtinhaltsstoffspektrum bezüglich Art und Konzentration kann auf Vor- und/oder Nachfilter verzichtet werden.In another embodiment of the method, the sorption stage comprises a main filter to which a pre-filter and / or a post-filter is optionally assigned. A post filter is preferably used. Pre- and / or post-filters can be dispensed with in the case of water with an almost uniform total range of substances in terms of type and concentration.
Gemäß einer bevorzugten Ausführungsform des Verfahrens werden als Vorfilter und/oder Nachfilter in der Sorptionsstufe vorzugsweise Pflanzenkläranlagen eingesetzt.According to a preferred embodiment of the method, the prefilter and / or postfilter in the sorption stage is preferably a plant based sewage treatment system.
Das mit Schadstoffen angereicherte Sorptionsmaterial, das als Substrat im Vergärungsprozess dient, wird vor der Vergärung in der Biogasanlage vorbehandelt. Damit kann der nachfolgende Vergärungsprozess beschleunigt werden. Das mit Schadstoffen beladene Sorptionsmaterial wird bei der Vorbehandlung mit Enzymen versetzt. Die Vorbehandlung erfolgt mit Enzymen, die die Schadstoffe und das Sorptionsmaterial hydrolysieren. Insbesondere werden Enzyme eingesetzt, die die Schadstoffe spalten.The sorption material enriched with pollutants, which serves as a substrate in the fermentation process, is pretreated in the biogas plant before fermentation. This can accelerate the subsequent fermentation process. The sorption material loaded with pollutants is treated with enzymes during the pretreatment. The pretreatment is done with enzymes that hydrolyze the pollutants and the sorbent material. In particular, enzymes are used that break down the pollutants.
Der im erfindungsgemäßen Verfahren bei der Vergärung entstehende Gärrest wird zur Entfernung gegebenenfalls noch vorhandener Schadstoffe enzymatisch nachbehandelt, um die möglicherweise verbliebenen Schadstoffe zu hydrolysieren.The fermentation residue produced in the process according to the invention during fermentation is enzymatically aftertreated to remove any harmful substances that may still be present, in order to hydrolyze the possibly remaining harmful substances.
Bevorzugt kann ein Gärrest, der Spuren von biologisch schwer oder nicht abbaubaren organischen Schadstoffen enthält, einer Nachbehandlung derart unterzogen werden, dass er mittels hydrothermaler Karbonisierung (HTC) in eine energetisch oder stofflich verwertbare Biokohle überführt wird, die Gärrestnachbehandlung also als HTC-Anlage ausgelegt ist.A digestate that contains traces of organic pollutants that are difficult to biodegrade or not biodegradable can preferably be subjected to an after-treatment in such a way that it is converted into an energetically or materially usable biochar by means of hydrothermal carbonization (HTC), i.e. the digestate after-treatment is designed as an HTC system .
Der Vorteil des erfindungsgemäßen Verfahrens besteht in der kontinuierlichen Aufbereitung von Wässern mit schwer abbaubaren Problemstoffen, die in geringen Konzentrationen gesundheits- und umweltschädlich sind. Die anfallenden problemstoffbelasteten Sorptionsmaterialien können in einem Vergärungsprozess vollständig verstoffwechselt werden und die als Endprodukt anfallende Biomasse kann bedenkenlos weiterbehandelt werden. Das Verfahren ist also Ressourcen schonend, da die vergleichsweise geringen Mengen an Reststoffen, die anfallen, stofflich und energetisch verwertbar sind.The advantage of the method according to the invention consists in the continuous treatment of water with problematic substances which are difficult to break down and which are harmful to health and the environment in low concentrations. The sorbent materials that are contaminated with problematic substances can be completely metabolized in a fermentation process and the biomass produced as an end product can be treated further without hesitation. The process is therefore resource-saving, as the comparatively small amounts of residual materials that arise can be used in terms of material and energy.
