NOVELTY - An animal waste processing method by film concentrating process involves subjecting livestock and poultry manure waste to anaerobic fermentation process, where the obtained product comprises marsh gas and fermentation residue. Solid and liquid portion of the fermentation residue are separated, and the slag is concentrated. The resultant concentrated slurry is subjected to secondary anaerobic fermentation process. The fermented product comprises marsh gas and biogas. The liquid is sent outside of the system through a conveying device for agricultural applications.    USE - Method for processing animal waste by film concentrating process for agricultural applications.    ADVANTAGE - The method enables effectively processing the animal waste in a simple and economical manner.    DETAILED DESCRIPTION - An animal waste processing method by film concentrating process involves subjecting livestock and poultry manure waste to anaerobic fermentation process in a fermentation reactor, where the obtained product comprises marsh gas and fermentation residue, where the marsh gas is sent outside of the reactor through a gas pipeline. The fermentation residue is subjected to a solid-liquid separating device having a solid-liquid separator. Solid and liquid portion of the residue are separated, and the slag is sent outside of the system through a conveying device. The conveying device is film concentrating device. The slag is concentrated, and liquid is separated from the concentrated slurry and discharged. The resultant concentrated slurry is passed into a secondary anaerobic fermentation reactor, where the fermented product comprises marsh gas and biogas, where the biogas is sent outside of the system through a gas pipeline. The liquid is sent outside of the system through a conveying device for agricultural applications.
