摘要：
The present invention relates to a biological treatment process where the influent to the biological treatment unit is deficient in carbon. Sludge is recovered from the wastewater stream and subjected to anaerobic digestion which produces biogas. The biogas is converted to syngas through an internal combustion engine reformer. Through a synthesis process, the syngas is converted to a carbon containing liquid stream that is utilized as a supplemental carbon source in the biological treatment process.
