Abstract

In order to treat and utilize urban fecal wastewater more effectively, a process for biochemical treatment of fecal wastewater from urban settlements was established in this study. After treating the fecal wastewater collected, solid and liquid organic fertilizers can be obtained. Compared to the commercially available urea, the solid organic fertilizer can increase the yield of okra by 12.89% at podding stage, while the liquid organic fertilizer can prolong the flowering period of Chinese orchid by 3 - 4 days compared to the untreated urine. Gases generated by various processing units are all collected to the biological deodorization system for treatment, which have no significant odor after treating through the system. The water outlet from the water reclamation system meets the national quality standards for urban miscellaneous water under urban wastewater reclamation and reuse.
