Iron-carbon microelectrolysis was used to pre-treat straw pulp and papermaking middle stage wastewater. Effect of iron dosage, iron/carbon ratio, initial pH, aeration and aeration pattern on the pollutant removal efficiency was investigated and the biodegradability of wastewater before and after treatment were compared. The results showed that the iron dosage affected pollutant removal slightly in...
The objective of this study is to further evaluate the relationship between removal effect of dissolved organic pollutants (DOC) and their characteristics (biodegradability, adsorbability and molecular size distribution) in different running stage of BAC filter. The experimental results showed that during early period of operation, BAC filter mainly removed adsorbable DOC (that is ADOC), but after...
