Waste treatment system

Abstract

A waste treatment system is herein described. A microbial additive containing a mixture of enzymes and bacteria designed to produce anoxic degradation of the waste is added to the waste composed of liquid waste containing solid content and the waste is shredded and mixed, thereby resulting in waste having a more homogeneous texture. The waste is then heated while shredding and mixing continues. The heating process eliminates pathogens. The result is that a combination of anoxic and anaerobic microbial activity within the waste is promoted while the organic portion of the solid content is largely dissolved into liquids, gases and biomass. Following heating, shredding and mixing, the treated waste separates into waste liquid and waste solid as the unsolubilized solids precipitate out of solution. Using a combination of augmenting specially formulated populations of bacteria and enzymes, shredding and mixing, anaerobic and anoxic conditions, elevated temperatures, solid liquid separation, and gas collection, the above described waste treatment system achieves the following objectives: reduce waste odour; solubilize organic waste solids into liquids, gases and biomass; reduce waste strength; stabilize waste; eliminate pathogens; separate remaining solids from liquids; remove and clean odorous gases generated by the reactions; maintain the nitrogen, phosphorus, potassium in the ratios and quantities necessary to promote the treated waste as a valuable fertilizer.
