Treatment of lignite-derived water produced from hot press upgrading by a combined A2/O-UBAF process
The water quality of lignite-derived water produced from Hot Press Upgrading (HPU) is in breach of the reuse standard for power plants circulating cooling water. This study assesses the water characteristics of lignite-derived water as follows: The BOD5/COD ratio is 0.85. The pH value of lignitederived water samples is from 6.65 to 6.85. The lignite-derived waters properties parameters such as turbidity, BOD5, CODCr, Mn and NH3-N are higher than the reuse standard for power plants circulating cooling water. A combined treatment process, A2/O-UBAF, was developed for remediation of the lignite-derived water in this paper. After the treatment, the lignite-derived waters quality can meet the reuse standard for power plants circulating cooling water in China.
