Bioorganically-augmented high value fertilizer

摘要

The invention is directed to processes for treating biosolids that result in high-value, nitrogen-containing, slow-release, organically-augmented inorganic fertilizer that are competitive with less valuable or more costly conventional commercially manufactured fertilizers. The process involves conditioning traditional waste-water biosolids and processing the conditioned biosolids continuously in a high throughput manufacturing facility. The exothermic design and closed loop control of the primary reaction vessel decreases significantly the amount of power necessary to run a manufacturing facility. The process utilizes green technologies to facilitate decreased waste and enhanced air quality standards over traditional processing plants. The fertilizer produced from recovered biosolid waste is safe and meets or exceeds the United States Environment Protection Agency (USEPA) Class A and Exceptional Quality standards and is not subject to restrictions or regulations.

主权项

1. A method for treatment of organic matter comprising:
forming an acidified paste of dewatered organic matter and one or more first acids; adding the acidified paste to a pressure vessel such that the pressure vessel maintains a predetermined head space pressure by the injection of steam; adding one or more second acids and one or more bases to the pressure vessel to combine with the acidified paste forming an exothermic mixture; subjecting the mixture to a temperature and pressure for a retention time, wherein the moisture content of the mixture is determined by the predetermined head space pressure and organic molecules in the treated and dried organic matter are partially or completely hydrolyzed or denatured; removing the mixture from the pressure vessel; and drying the mixture.
