    摘要： The invention is a method of two-phase anaerobic digestion where monitoring and adjusting the nitrogen status (carbon to nitrogen molar ratio, i.e. C/N molar ratio or total or ammoniacal nitrogen content) enables maintaining optimum conditions during the process. The method improves the use of a variety of feedstock materials or facilitates monodigestion of one feedstock. Especially the introduction of nitrogen rich feedstock materials in the process is amended. A community of hydrolyzing and acidogenic microorganisms in the first phase digester performs ammonification i.e. release of organic nitrogen as ammonia. Nitrogen and phosphorus are removed and recovered from the digestate which then undergoes biogasification in the second phase of the process. Reject water from biogasification can be recycled within the process.

    摘要翻译： 本发明是一种两相厌氧消化的方法，其中监测和调节氮状态（碳与氮的摩尔比，即C / N摩尔比或总氮或氨含量）能够在该过程中保持最佳条件。 该方法改善了各种原料的使用或促进一种原料的一次消化。 特别是在此过程中引入富含氮的原料。 第一阶段消化器中的水解和致酸微生物群落进行氨化，即作为氨释放有机氮。 从消化物中除去氮和磷，然后在该过程的第二阶段进行生物气化。 生物气化废水可以在生产过程中回收利用。

    摘要： The invention provides a process for producing ammonia or ammonium from an organic material, the method by contacting the organic material with at least one hydrolytic enzyme, in a medium, to produce a medium including hydrolyzed or partially hydrolyzed organic material suitable for microbial fermentation. The hydrolyzed or partially hydrolyzed medium with organic material is then fermented in the presence of at least one microorganism capable of ammonification, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product that comprises ammonia or ammonium. The organic material includes nitrogenous compounds suitable for conversion to ammonia or ammonium.
