- Abstract:
- Compared with the landfill leachate, the leachate compressed from garbage transfer station has high organic content, high BOD5 to COD ratio (more than 0.4) and good biodegradability. In addition, its pollutant composition is relatively complex, and the wastewater quality and quantity fluctuate greatly with time. A leachate treatment plant with treatment scale of 200 t/d is located in a northwestern city. The treatment process consists of mesophilic anaerobic digestion, enhanced membrane bioreactor system (two-stage A/O and MBR), nanofiltration and roll reverse osmosis, and the effluent quality is required to meet the limit in table 2 specified in Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008). The concentrated solution is treated by the process of pretreatment, high pressure reverse osmosis and submerged combustion evaporation. The actual operation shows that the effluent quality reaches the discharge standard and the full quantification treatment of leachate is realized.
