- Abstract:
- This paper presents the zero discharge and resource recovery practices at the Nanjing Jiangbei domestic waste incineration power plant,which processes 800 m3/d leachate. The treatment system integrates multiple technologies,including pretreatment, upflow anaerobic sludge blanket filter reactor (UBF), two-stage A/O-MBR, nanofiltration(NF), and reverse osmosis(RO). The NF concentrate is treated using membrane reduction followed by back-spray incineration, while the RO concentrate undergoes softening, STRO reduction, and lime slurry treatment. Additionally, pretreated biogas is sprayed into the incinerator for co-combustion to generate electricity. The system operates stably with a recovery rate of over 83.0%. The treated effluent is reused for cooling water supplementation, and the electricity generated from biogas co-combustion meets the power demands of the leachate treatment system. This project demonstrates a successful implementation of zero discharge leachate treatment,achieving full resource recovery and wastewater reuse.
