Abstract:

This study takes the landfill leachate nanofiltration and reverse osmosis concentrate as the treatment object, adopts the flocculation precipitation electro process to pre-treat the nanofiltration concentrate, and the mixed solution of reverse osmosis concentrate as the treatment object, and adopts the combined process of A/OMBR process Fenton deep treatment, with 30 mg/L sodium chloride acclimatized sludge as the seed sludge, to investigate the removal of the main pollutants COD and total nitrogen in the mixed solution of nanofiltration and reverse osmosis concentrate. The results show that after the mixed solution of nanofil and reverse osmosis concentrate is treated by this combined process, the effluent can meet the discharge requirements of Table 4 in the Pollution Control Standards for Municipal Solid Waste Land Site (GB16889-2024).
