摘要:
A method and an apparatus for biological wastewater treatment that includes a biological selector and a physical selector. The apparatus comprises an internal biological reactor where wastewater and recycled biomass are combined to provide a high substrate and high electron acceptor gradient for generating morphological biomass features that favor granule formation over floc and filament formation, and an external gravimetric or external screen selector operating on the biomass waste stream for collecting and retaining densified biomass aggregates including dense granule selection and for wasting lighter filaments and flocs. In the method and apparatus, particles may be added to provide cores to promote the formation of aggregates encapsulating the seeded particles. The particles may be added as various materials, for example, in the bioreactor, to initiate or seed the formation of a granule, that could then be separated by or integrated with either the external gravimetric or external screen selector. Further, organisms may be selected for biological phosphorus removal, denitrifying methane oxidizers, biological sulfur or sulfide oxidation, methanogenesis.

A liquid fuel production method of the present invention includes: a saccharification step in which a biomass is saccharified; a methane fermentation step in which a saccharified liquid acquired in the saccharification step undergoes methane fermentation; and a biogas to liquid (BTL) step in which a liquid fuel is generated from a biogas acquired in the methane fermentation step.
摘要:
The present invention is a cellulose-based biomass juicing method in which a cellulose-based biomass is chipped, and the cellulose-based biomass is juiced after a predetermined pre-treatment is performed on the cellulose-based biomass, wherein the pre-treatment is a mechanical treatment in which parenchyma constituting the cellulose-based biomass is crushed.
摘要:
A plant processing system of the present invention includes: a plant cultivation facility (1) which cultivates plants including a sugar solution; a crushing facility (2) which crushes plants felled in the plant cultivation facility (1); a juicing facility (3) which harvests sap from plant chips obtained by the crushing facility (2); a methane fermentation facility (5) which performs a methane fermentation process on the sap; and a power generation facility (6) which generates electric power using a biogas obtained by the methane fermentation facility (5) as a fuel.
摘要:
Offenbart wird ein Verfahren zum Erzeugen von Biogas durch Vergärung von pumpfähigen organischen Ausgangsmaterialien, insbesondere von Güllen und Jauchen aus der Tierhaltung, wobei - ein Zustrom des organischen Ausgangsmaterials aufgeteilt wird in einen Dickstoffanteil mit gegenüber dem Ausgangsmaterial höherem Feststoffanteil und einen flüssigkeitsdominierten Dünnstoffanteil mit gegenüber dem Ausgangsmaterial geringerem Feststoffanteil, - der Dünnstoffanteil einem Dünnstofffermenter (23), in dem Mikroorganismen auf in dem Füllvolumen des Dünnstofffermenters (23) in der Schwebe gehaltenen Aufwuchskörpern (27) aufgewachsen sind, zugeführt und dort fermentiert wird, - in dem Dünnstofffermenter (23) entstandenes Biogas aufgefangen und für eine weitere Verwendung abgeführt wird, - in dem Dünnstofffermenter (23) entstehende Gärreste abgeführt werden. Dieses Verfahren erlaubt den Betrieb von kompakten und zu günstigen Investitionskosten herzurichtenden Anlagen zur Biogasgewinnung. Eine hier ebenfalls offenbarte Vorrichtung zum Erzeugen von Biogas nach dem Verfahren ist insbesondere modular aufgebaut mit straßentransportfähigen Modulen.
摘要:
The invention relates to the use of at least one bacterial amylase and/or bacterial or fungal cellulase in combination with one or more protease(s) in substrates for anaerobic digestion processes for biogas production for improving degradation of maize, maize silages and/or other biogas substrates, in particular for improving gas yield, velocity and substrate conversion rate.
摘要:
There is provided a process for growing a phototrophic biomass in a reaction zone, wherein the reaction zone includes a reaction mixture that is operative for effecting photosynthesis upon exposure to photosynthetically active light radiation, wherein the reaction mixture includes phototrophic biomass that is operative for growth within the reaction zone. The process includes supplying at least a fraction of gaseous exhaust material, being discharged from an industrial process, to the reaction zone, exposing the reaction mixture to photosynthetically active light radiation and effecting growth of the phototrophic biomass in the reaction zone, wherein the effected growth includes growth effected by photosynthesis, and modulating distribution of a molar rate of supply of carbon dioxide, being exhausted from the reaction zone, as between a smokestack and at least another point of discharge.
摘要:
This invention pertains to a composition, which is a natural and organic pesticide, specifically for mitigating, controlling and treating fungicidal, virucidal and bactericidal pathogenic microorganisms in agricultural products such as root crops, fruits and vegetables. Examples of such disease-causing microorganisms are Mycosphaerella fijensis causing black Sigatoka disease in Cavendish (banana), Ralstonia solanacearum causing Moko disease in Cavendish (banana), Lasiodiplodia theobromae causing soft rot or fruit rot in crops and fruits, Fusarium oxysporum causing Panama wilt in fruits and crops, and many others. The composition is a fermented product of tropical plants, carbon source, protein (nitrogen) source, and a carrier agent. The fermented product may help strengthen the plant's immune system to fight pathogenic diseases. Since all the major constituents of the composition are generally regarded as safe, this natural pesticide is found to be non-toxic and safe to humans and animals, and environmentally benign.
