Abstract:
1. A method of treating a liquid biological waste stream containing solid particles, and active biological or toxic waste components to provide a treated waste stream comprising the steps of: flowing said waste stream containing solid particles into a waste treatment apparatus; macerating the waste stream to reduce a size of the solid particles in the waste stream; exposing the macerated waste stream containing solid particles to metal ions to disinfect the waste stream and to promote oxidation, wherein the metal ions comprise ions selected from the group consisting of aluminum, zinc, silver, iron, and copper ions; preheating the metal ion exposed waste stream; and oxidizing the waste stream in the presence of the metal ions by exposing the waste stream to an oxygen-containing gas at a temperature effective for wet oxidation of the waste stream to provide a treated stream that is substantially devoid of toxic and active biological materials.
