Outline of Final Research Achievements

To expand the applicability of DHS bioprocess, various wastewaters were tested by using DHS bioreactor in combination with other pre-treatment technologies. Mainly, the applicability of landfill leachate and nitrification of phenol-containing wastewater was investigated. The effects of salt concentration on nitrification were quantitatively evaluated. Physico-chemical and microbial approaches were used clarify DHS treatment mechanisms.
