    摘要: The invention is directed to systems and methods of biological and chemical treatment of wastewater comprising organic nitrogen compounds. Systems may include: an aerobic reactor, a first separation module for separating liquid and solid components of the wastewater; an oxidation module for removing organic materials from the wastewater; and a post-anoxic reactor for denitrifying at least a portion of the wastewater. Systems may include a second separation module and various feedback recycle lines between the components. Methods may include: degrading by the aerobic reactor more than 95% of organic compounds to ammonia, oxidizing by the oxidation module at least a portion of the ammonia to nitrates, and degrading by the post-anoxic reactor at least a portion of the nitrates to nitrogen gas and water. Systems and methods may reduce total organic carbon of the wastewater by more than 90%, and total nitrogen of the wastewater by more than 90%.

    摘要: The present invention describes methods for the detoxification of a mixture of nitrile compounds, or a mixture of nitrile and amide compounds by conversion of the nitrile compound(s) to the corresponding amide or acid compounds using a pure culture of an induced microorganism strain capable of converting a nitrile moiety to an amide or acid moiety. If an amide is formed or is present in the mixture, the amide can be further converted, using the present methods for detoxification, to the corresponding acid. The acid can then, if desired, be further degraded to CO.sub.2, H.sub.2 O and biomass. The induced pure cultures are able to detoxify a mixture of nitriles or a mixture of nitrites and amides which are typically present, in high concentration(s), in nitrile production waste streams. The present invention further discloses methods for removing a nitrile compound from an amide preparation, such as an acetamide or acrylamide preparation containing an unwanted nitrile compound, using an induced pure culture of an induced microorganism strain capable of converting a nitrile moiety to an amide or acid moiety. The pure cultures are able to purify or reduce the toxicity of the amide preparation thus improving purity and amide product yield from the amide preparation. The present invention further discloses methods for the conversion of a mixture of amide compounds to the corresponding acid compounds using a pure culture of an induced microorganism strain capable of converting an amide moiety to an acid moiety. This invention also discloses kits, biofilters and methods for use of the kits and biofilters for detoxification containing the useful microorganism strains.

    摘要: A two-stage apparatus for the purification of cyanide-containing waste water allows relatively clean water to be obtained from waste water containing high concentrations of cyanide and solids in suspension. The apparatus in its first stage includes a bioreactor having a biocultivator (27) for cultivating microorganisms. A reservoir means (1) in communication with the cultivator (27) is provided for receiving and treating a mixture of waste water and microorganisms, having a downwardly converging conical base. Oxygenating means (8) are provided in a region proximate the conical base, for supplying oxygen to the mixture. Temperature regulating means (7) and stirring means in the form of a stirrer or pump (6) are also provided. The second stage of the apparatus comprises a sorption chamber (28) in communication with the reservoir means, for containing an ion-exchange resin, activated carbon, charcoal, or other sorption material. Oxygenation means (31) and an airlift (32) for stirring the mixture are provided in conjunction with the sorption chamber (28). Conduit means (33) are further provided to allow the mixture of sorption material and waste water at the second stage to be thrown onto an inclined straining screen (34), whereby said sorption material may roll down the screen back into chamber (28), while the cleansed water passes therethrough and may be collected.
