Open publisher page 0 citations

Abstract

Anaerobic filter and aerated filter belong to a kind of biological membrane method. Domestic wastewater was treated by anaerobic biological filter and aerated biological carbon filter under the condition of the lower temperature in spring. The objective of the research is to investigate a low-cost way of wastewater treatment. The results showed that the COD removal was as high as 83% when HRT was 14 hours. In the range of 0.4—1.2 m·h~ -1 ,the TOC removal in aerated filter was higher than in anaerobic filter, but the TN removal is reverse .
